I found a duplicate image of U-Boot at 0x07F I don’t know this device, but the datasheet says p.

Are you sure the remap even happens during this relocation? Sign up using Email and Password. You can prove this for yourself by single stepping through the code.
Samples are planned from April The left side describes code modules and boot sequence, and the right side are physical memories with the installed or loaded indicated with arrows programs. Also see this thread on AT91RM bootloaders to boot into u-boot.
R14 CORRUPTED DURING CLOCK INTERRUPT ON AT91RM9200
Performing a mtest 0x 0x07F at91dm9200 and overwrote all but the highest megabyte of RAM, and proved that the U-Boot loaded at 0x03F was no longer being executed. There’s also mention of an “atmel appnote” apparently about AT91RM bootstrap, but I cannot find it at the Atmel site. According to the boot overview p. Stack Overflow works best with At1rm9200 enabled. That code doesn’t tell us anything without any actual values for all the addresses involved.
The code snippet you’ve posted is written using position independent code. It builds on our experience and partnerships established with ARM7-based systems, notably with our qualified third-party development tools supplier, Green Hills Software. Examples include telematics systems connecting GPS receivers and GPRS communications, industrial automation, medical at91tm9200 and point-of-sales terminals.
