1 INTRODUCTION AND OVERVIEW

These Firmware Release Notes describe the current state of firmware for the U700 Series Product families of HSDPA modems. The products covered in this release are the Merlin U730 and U740 Cardbus modems, and the Expedite EU730 and EU740 MiniCard modems.

2 RELEASE LABEL

The firmware revision present in a particular modem can be ascertained by executing the ‘AT+GMR’ or the ‘ATI’ command. The revision string is formatted as follows:

‘a-b [yyyy-mm-dd hh:mm:ss]’

where ‘a’ is the build number of the application code; ‘b’ is the build number of the boot code; and ‘yyyy-mm-dd hh:mm:ss’ is the date and time that this build was created. Note that not all builds will be released externally. That is, the releases supplied to end-users may not be consecutively numbered.

The release described in this document is labeled as:

‘27.2-27.2-00 [2006-04-28 11:27:20]’

Note that the same release label is used on sets of releases for different models. Each firmware “model” is targeted to a particular hardware platform and is not interchangeable. The model number of a particular firmware release can be ascertained by executing the ‘AT+GMM’ or the ‘ATI’ command.

3 CHANGES FROM PREVIOUS RELEASES

3.1 Build 27.2

The following changes were introduced in Build 27.2

456/457Integrated in Qualcomm Patch Release SBA_M6275BKMRZ326002_A_Novatel_042706

The following items were addressed within this patch:

USB issue:

CR 89722: STMR TTI 7 CFN 6 mismatch - Possible INTLOCK()




CR 817249: Intermittent USB enumeration failure.

2G-3G issue:

CR 88558: Incorrect QSearch_I passed by RR ( No 3G measurements)

CR 91668 GSM BCCH decode Failure

450 Integrated in Qualcomm Patch Release SBA_M6275BKMRZ326002_A_Novatel_042406.

This patch correct the SR #818351 issue (FACH – DCH transition causes UE to reset (associated CR #88032)

447 While PDP context activated the LED indication was not properly updated when transitioning between EDGE to GPRS and GPRS to EDGE.

3.2 Build 27.1

The following changes were introduced in Build 27.1

440. Correction to LED indication of High-Speed Service

- EDGE service was not properly indicated (when attached to the Agilent 8960).

- PDP Context activation while operating on the Agilent 8960 would not display the Yellow indication for HSDPA.

442 Merged in Qualcomm Patch Release SBA_M6275_Novatel_326002_A_040506.(addressed: CR: 89847 Test case 8.3.5.3 failure)

3.3 Build 27.0

The following changes were introduced in Build 27.0.

434. Added new LED support for EDGE and HSDPA indication.




The following table summarizes the LED Cadence and Color supported by this build. In addition, a custom AT command ($NWHLED) was added to set the hysteresis value for the HSDPA LED indication. The default hysteresis value is set to 250 msec. The hysteresis value (if changed) will be stored in NV RAM and will be maintained during power off. Carriers can specify the time value of the HSDPA hysteresis through the Customer PRI document.

AT$NWHLED=0, <hysteresis> Where <hysteresis> is an unsigned integer value in milliseconds. This is the delay from when a HSDPA session is terminated to when the HSDPA indication is removed from the modem. The minimum hysteresis default value is currently set at 250 milliseconds.

Example: AT$NWHLED=0,10000This will set the HSDPA LED hysteresis to 10 seconds.

LED Cadence & Color

PDP YELLOW ON The modem is currently PDP context activated on the HSDPA system.

PDP MAGENTA ON The modem is currently PDP context activated on the EDGE system.

433. Added fix for the Cell Broadcast configuration file (EFCBMI) overwrite issue. The Cell Broadcast Configuration information is read from NV RAM and the USIM, which is then merged together, and then written back to the USIM. NV RAM may contain more entries than the USIM which when written back to the USIM could overwrite the original entries. Under certain conditions the re-write would replace the original USIM information.

432. Enhanced support for GSM 7-bit alphabet. Carriers that use the EFPNN file to store/display network names would have encountered this issue. The problem became apparent when packing ASCII characters greater than 0x7F into the equivalent GSM 7-bit alphabet. The expected character would not have been properly displayed.

431. Added customer request for change to Cell Reselection to new LAI after reception of reject cause #15. An NV item has been created to allow carriers to decide on the method used for cell reselection after receiving the REJECT CAUSE #15. The desired setting of this NV item can be chosen through the Customer PRI document. Carriers may choose between the default implementation (search current RAT only) or the alternative implementation (search all RATs – WCDMA, GSM - which will take a bit more time).

430. Merged in Qualcomm Patch Release SBA_M6275_Novatel_326002_A_032206. This patch address’ CR 88961 (PS sessions dropped due to UE originated Cell-Update Message (100% BLER) ) and CR 88714 (Test case 7.2.3.35 (34.123) fails).

428/424. Added fix for the SIM and USB Suspend issue. It was noted that with some SIMs the data card would loose the ability to communicate with the SIM upon returning from the USB Suspend state (+CPIN would return SIM FAILURE). Also, once the SIM issue was resolved, it was discovered that the USB Suspend State design was missing a critical state that would allow normal mode of operation upon returning from the “deep sleep” state.

426. Merged in Qualcomm software patch to address the following issue:

SR# 796467 - Data Card resets upon receiving a USSD message from the network.




SR# 796473 - MT USSD are not properly displayed.

423. Addressed issue with AT+CPIN? It returned an improper error when PUK2 is permanently blocked. PIN 2 permanently blocked is now displayed for this error condition instead of SIM FAILURE.

422. Fixed Band Preference NV corruption issue when an internal NV backup is performed (observed when flashing to Build 26.0).

421. Merged in the AMSS 6275 Release 3.2.60 (M6275BKMRZ3260) code from Qualcomm. All of the changes (SR and CR) are described within Qualcomm Document “AMSS 6275 Release 3.2.60”. The document number and release date are “80-V8100-57 A” and “March 3, 2006” respectively.

Merged in the AMSS 6275 Release 3.2.6002 (M6275BKMRZ326002) code from Qualcomm. All of the changes (SR and CR) are described within Qualcomm Document “AMSS 6275 Release 3.2.60”. The document number and release date are “80-V8100-63 A” and “March 17, 2006” respectively.

420. Added support for the “_” (underscore) character in the APN String.

418. Fixed AT Argument Pointer Issue (raised from the AT$CNTI=0 issue that would return ERROR instead of the current RAT).

416. Fixed issue with +CPBR. Using an Axalto SIM and the +CPBR command would always returns SIM BUSY.

Fixed issue with being unable to read the FDN List.

3.4 Build 26.0


413. Qualcomm created a feature that causes the SIM to be powered down when AT+CFUN=0 is executed. This prevents the modem from being reinitialized with AT+CFUN=1, since the modem has to be reset (AT+CFUN=7) before it can start up again. This feature has been disabled to prevent this behavior.

412. Added in USB Selective-Suspend (Host enabled Selective Suspend) functionality.

403. Merged in the AMSS 6275 Release 3.2.50 (M6275BKMRZ3250) code from Qualcomm. All of these changes are described in Qualcomm Document “AMSS




6275 Release 3.2.50”. The document number and release date are “80-V8100-55 A” and “January 31, 2006” respectively.

3.5 Build 25.0


407. Removed the check within the procedure "nvio_write_fid", that would only allow the factory ID to be written to once.

Removed "SIM Secure" addition from the partition table (added from the Qualcomm 3.2.401/.40 merge and restored the start blocks back to the old partition table setting. This restoration was performed to ensure we had backwards compatibility with previous release builds.

3.6 Build 24.0


404. AT+CPBS=? displays the available phonebook memory storage. Currently, there is no support to read the FDN list (amongst others). A change has been incorporated to allow users with the ability to read any phonebook memory on the SIM.

402. Add support for 2 AT ports using clear text (no DM on secondary port).

397. A temporary change was made to address the issue with the AT+CPBR (read phonebook) returning +CME ERROR: unknown when a 'special character' is encountered. The phonebook read shops with the CME ERROR response, even though there are valid phonebook records after the record containing the special character. The workaround is to ignore the special character (> 0x7F) and display a “best representation” of the character. This in not an ideal fix but it will due until Qualcomm has completed their PBM re-development work.

396. (SCR 368) Added fix for 2G-3G issue (removal of: FEATURE_IMMEDIATE_RESEL_AT_LOW_CPICH_ECIO)

(SCR 372) AT+COPS? now supports the SIM SPN Elementary File for displaying the Carrier Name.

(SCR 386) Added the custom AT$NWHFP command to allow one to specify a WCDMA downlink frequency.




The format of the custom AT$NW command is as follows:

Command: AT$NWHFP <enabled>, <frequency>

Description: HSDPA Frequency Prioritization. Allows the user to set a preferred frequency. Intended for testing purposes only.

Syntax: AT$NWHFP=0 disables frequency prioritization

AT$NWHFP=1,<freq> enables frequency prioritization at a specified frequency

AT$NWHFP? <0-1>, <freq>

(SCR 389 from SCR286) – Corrected AT+CPBW write to phonebook issue.

(SCR280) – Added AT$NWCSQ command (displays RSSI, Ec/Io and BLER information.

(SCR273) – Fixed issue with secondary port command processor.

When commands are being executed on the primary and secondary port simultaneously, occasionally a blank response will be returned to the secondary port. The next command issued on the secondary port will get responses for the previous and current commands.

Also, sometimes a command executed on the secondary port will timeout before returning, but will contain a response when it returns (that was ready long before the time-out period).

395. Merged in the AMSS 6275 Release 3.2.401 (M6275BKMRB32401) code from Qualcomm. All of these changes are described in Qualcomm Document “AMSS 6275 Release 3.2.401” (Thin UI, NAND). The document number and release date are “80-V1736-39 A” and “January 9, 2006” respectively.

This merge also incorporates the changes that occurred within the AMSS 6275 Release 3.2.40 (M6275BKMRB3240). Details of additions and fixes can be found in the “AMSS 6275 Release 3.2.40” (Thin UI, NAND). The document number and release date are “80-V1736-37 A” and “December 2005” respectively.

3.7 Build 23.0





393. Merged in the AMSS 6275 SBA Patch Release 3.0.3498 (M6275BKMRB303498) code from Qualcomm (see following notes from Qualcomm).

SBA FOCUS: Additional, consolidated and updated fixes for the following mostly based on actual and replicated carrier acceptance tests deemed essential for carrier launch.

1. A pair of critical GERAN issues sought by OEMs and/or revealed in tests.

2. A simple UMTS change to avoid a fatal-error.

GERAN modem updates:

CR 85213: PSI2 decode failure leading to reset on UECR 81912: Band Indication change on fly is not informed to L1 by RR resulting in HO

failure.

383. Merged in the AMSS 6275 SBA Patch Release 3.0.3497 (M6275BKMRB303497) code from Qualcomm (see following notes from Qualcomm).

SBA FOCUS: Additional, consolidated and updated fixes for the following mostly based on actual and replicated carrier acceptance tests deemed essential for carrier launch.

1. GLLC fixes to address potential out-of-bound array access

2. PBM access optimization - first cut - to reduce SIM access times

3. Fix for device reset when USB remains connected across power-cycle

4. Fix for data-abort in GPRS physical-layer in transfer mode

5. UIM fix to not let call continue after SIM is removed




6. Additional script, binary and release packaging cleanups

7. Faster initialization of phone-book manager (SR 779681)

8. Restoration of test-box level compatibility for PCA-2 (but without any functional or performance guarantee).

9. CR 82579: FFA resets if USB to UART cable is inserted while FFA is on (SR 776743).

10. CR 82879: Potential issue in GLLC code: array accessed beyond bounds (SR 777737).

11. CR 84191: Data abort in GPL1 transfer mode. NULL value of dl_tbf_ptr (SR 782647)

382. AT+CSQ returning incorrect value (+CSQ: 31,99) on power up (this still may be an issue under certain conditions – Novatel Wireless is currently investigating).

381. For the EU/U730 the Power Class reported to the network for WCDMA is Power Class 4. For the EU/U740 the Power Class reported to the network for WCDMA is Power Class 3. (Power class 3 was initially being reported for both for device types).

378. Merged in the AMSS 6275 SBA Patch Release 3.0.3493 (M6275BKMRB303493) code from Qualcomm, (see following notes from Qualcomm).

SBA FOCUS: Additional, consolidated and updated fixes for the following mostly based on carrier acceptance tests.

1. Modem DSP firmware fixes for several critical show-stopping CRs in performance.

2. UMTS access-stratum fixes for a searcher re-initialization issue

3. CR 82085: Fix AGC race condition bug causing fatal error in L1M due to bad status from mDSP go-to-sleep command.

4. CR 82654: GCF: Fix for TPC reject immediately after compressed-mode gap in multiframe gaps.

5. CR 83194: Set HDET trigger point to fix max power higher than expected in compressed-mode slots (power oscillation).

6. No CR: Fix for 100% BLER after radio-bearer re-configuration on FACH-to-HSDPA transition.

7. CR 81537: Searcher timing adjustment changing especially after hard hand-over scenarios.




377. For the EU730/740 the Power Class supported for GSM is Power Class 4 (850/900 Band). For the U730/740 the Power Class supported for GSM is Power Class 5 (850/900 band).

376. Changed Windows 'Connect' Message Bubble Status to report 1.8Mbps for HSDPA, 384kbps for WCDMA and 237kbps for EDGE/GPRS. This represents the ideal maximum speed that is possible not what has been granted by the cell (this fix requires new Window drivers otherwise the ‘Connect’ Message Bubble will default to 230.4kbps for all technologies).

374. Adjusted the RSSI reported values as follows:

5 bars for -71 dBm or stronger (exceptionally strong signal)4 bars for -81 to -70 dBm (quite good signal)3 bars for -91 to -80 dBm (satisfactory signal)2 bars for -95 to -90 dBm (weaker signal)1 bar for -110 to -96 dBm (borderline unusable signal)

3.9 Build 21.0


369. Synchronized the LED update call for the Diagnostic command (CMDIAG_CONTROL) and the AT$NWWDIS command. This eliminates the differences observed in the LED operation between these two commands.

367. Added message support for the “modulation based multiclass bit”. 366. Fixed wireless disable state issue that occurs on some laptop reboot.

364. Fixed issue with the Network Personalization Lock and UICC’s (USIMs).

3.10 Build 20.0


363. Fixed issue with the reporting of the NWERR Event.

362. Added Thermal Bit indicator to the modem snapshot result.

3.11 Build 19.0





338. Add report of SVN number to Modem Status report

Provided the ability for any type of Connection Manager Software to report the Firmware Version number that is reported to the network. This is achieved through the modem’s DM command.

346. Added AT command for date of manufacture

Provide an AT command that will query the data of manufacture.

According to the specifications, the Factory ID contains that information in the form: "NMddmmyyXRRRRR". The command added as $NWMFG? returns the manufacture date as "January 12, 2005" or similar based on the numeric date format listed here.

357. USB enumeration of EU730 on computer peripheral.

It was discovered that Build 13 was the last load that could be powered up in a laptop and be enumerated. Builds after 14 would not be enumerated when used in this test.

After testing this scenario, it was found that the USB driver could get stuck in two different conditions:a) in a state where it was waiting for the host to draw DP low as a USB reset signal. In this condition, it is likely that the host already did this and it was missed for some reason.b) in a suspended state, due to an apparent physical disconnect from the host.

Entry into either of these modes will cause the unit to fail enumeration either because it has not correctly returned from the suspended state, or because it believes that it is not connected to the host.

After discussion, we believe that the best solution is to ignore any/all transitions to either of these states, because they have no meaning in our devices. We will instead remain as a USB B peripheral and never leave this PM state.

359. Implemented SV Number Updating.

Turned on SV Numbering. Currently this is set to 0 for all release builds. Need to turn on the auto-increment feature in the release build script and make provisions for having different SV numbers for the U700 and U700W builds.

360. Removed check for Limited Service in AT+COPS? Command.




The Carrier Name shall be displayed instead of displaying “No Service” when the modem is operating in Limited Service. The Connection Manager Software shall now handle displaying error conditions when the user is unable to connect to the network when in this state.

4 KNOWN PROBLEMS

4.1 QCT REPORTED

The known reported problems are contained in the latest release notes for the current QC base revision. Please refer to the latest release notes of this version from QC for more information.

4.2 NOVATEL WIRELESS REPORTED

Build 27.0

The LED state indication may be improperly display when camped on an EDGE network.

Build 25.0

Others:

One of the changes included in the QCT M6275BKMRB303486 release relates to the operation of the CFUN command. This change enforces a requirement that the CFUN? command (to query the current mode) execute before any CFUN=x mode change is executed. We believe that the reason for this change is to enforce the fact that CFUN must be informed of the current mode before a mode change can occur from this mode to a new mode (many transitions in mode are prohibited if you are not in the correct current mode).

We are currently investigating the rationale for this change and would like to automate this procedure so that any mode change request using CFUN will automatically query the current mode before operating, but we do not fully understand why the change was made originally. In the meantime, it is suggested that any use of the CFUN command to perform mode switching take place only after a CFUN? of the current mode has been executed.
