2.4 Powering Up the Board

The AT91SAM9G20-EK requires 5V DC (±5%). DC power is supplied to the board via the 2.1 mm by 5.5mm socket J1. Coaxial plug center positive standard.

2.5 Backup Power SupplyThe user can plug in a battery (3V Lithium Battery CR1225 or equivalent) in order to permanently powerthe backup part of the device. In this case, J10 configuration must be set in position 1, 2. Refer to Sec-tion 4.1 ”Jumpers”.

2.6 Getting Started

The AT91SAM9G20-EK evaluation board is delivered with a CD-ROM containing all necessary informa-tion and step-by-step procedures for working with the most common development tools.

Configuration

4.1 Jumpers

Note: 1. These jumpers are provided for power consumption measurement. By default, they are closed. To usethis feature, the user has to open the strap and insert an ampere meter.

Table 4-1. Jumpers Configuration

Designation Default Setting Feature

J2 Closed 3.3V Jumper(1)

J3 Closed

Forces power on. To use the software shutdown control:• J3 must be opened,• 3V battery backup must be present,• J10 jumper set in position 1-2

J6 Closed VDDPLL Jumper(1)

J7Open Enables boot on the internal ROM

Closed Enables boot on the NCS0

S1 Opened Disables the ICE NTRST input

S2 Opened Selects ICE Debug Mode or JTAG Boundary Scan Mode

S3 Opened Disables TCK <-> RTCK local loop. If S3 is closed, R13 must be unsoldered.

R13 Soldered Enables the ICE RTCK return. S3 must be opened

R14 Soldered Enables the ICE RTCK return. S3 must be opened

Configuration

4.5 Ethernet

RMII is the factory default mode. To evaluate the MII mode, the user has to unsolder R49, R50, R127and close S7 and S8. When the RMII mode is used, the user can use the specific MII signals as PIO, butthe following resistors must be unsoldered (R119 to R126).

Note that, by default, resistors R112 and R120 are not populated in order to avoid contention betweenthe MII signals and the SD Card slot J35. If the Ethernet MII mode is implemented on the board, then youmust not insert any card into slot J35. Otherwise, signal conflicts could occur and damage both theEthernet controller and the SD Card.

4.6 Miscellaneous

Refer to “Board Layout - Top View” in Section 5.1 ”Schematics” for the PIO Usage.

Section 6

Errata

6.1 Wrong Silkscreen of BB and 1.0V on the Board

There is a silkscreen reversion on the board, for the selection of the VDDBU source:

On J10 position 1-2, the marking should be ‘BB’ for Battery Backup instead of ‘1.0V’

On J10 position 2-3, the marking should be ‘1.0V’ instead of ‘BB’.

This erratum is not applicable for AT91SAM9G20-EK Rev. C and later versions.

6.2 Choice of an Oscillator Capacitance

For many reasons at the manufacturing level, Atmel does not specify any crystal references at the boarddesign stage.

Because of that, the user can find an inconsistency in the value of the used capacitance of the18.432 MHz crystal on each pin (C23, C24), and the nominal load capacitance of the crystal.

As a reminder, here is the way to select these values.The electrical parameter allows you to fit the rightvalues provided by the crystal manufacturer - and not by Atmel. They are called "Load Capacitance" ofthe crystal. You have to take stray capacitances (package, socket, trace) into account in order to beclose enough to the equivalent nominal Load Capacitance.

With the on-board HCM49-18.432MABJT crystal reference, 10 pF capacitances have been fitted on the18.432 MHz crystal for a nominal 27 pF load capacitance.

6.3 SD Card Slots and Booting Capability

On the board, Slot J13 is incorrectly marked with a “bootable” mention (solder side). This should beapplied to J35 instead. However, the schematic entitled ” Memory” attached to this User Guide, in Sec-tion 5.1 ”Schematics” does represent the correct location and marking.
