Appendix A

U-Boot CommandsDas U-Boot supports an extensive command set. This section describes the

most useful of those commands. Because U-Boot is highly configurable, not all

commands are necessarily in any given implementation. The behavior of some

commands is also configuration-dependent and may depend on environment-

variable values.

All U-Boot commands expect numbers to be entered in hexadecimal. In the

following descriptions, arguments are bracketed by < >. Optional arguments are

further bracketed by [ ]. Command names can be generally abbreviated to the

shortest unique string, shown in parentheses.
