A sophisticated power management controller provides a range of clock speeds and at91rmm9200 individual peripherals to be powered down when not in use.
However I’m unable to figure out where the memory remap operation is happening in the code. Sign up or log in Sign up using Google.

Samples are planned from April The salient text is ” There’s also mention of an “atmel appnote” apparently about AT91RM bootstrap, but I cannot find it at the Atmel site. There is no hardware remapping going on here. The code snippet you’ve posted is written using position independent code. U-Boot, after being loaded into main memory, may relocate itself to high memory in order to maximize available memory.

Can anyone please help me understand the remap operation in u-boot and show me the code corresponding to this? Sign up using Facebook.
It targets applications requiring enhanced performance such as host processors for system control and connectivity. The internal ROM contains proprietary Atmel code that is not published.

Examples include telematics systems connecting GPS receivers and GPRS communications, industrial automation, medical systems and point-of-sales terminals. Performing a mtest 0x 0x07F tested and overwrote all but the highest megabyte of RAM, and proved that the U-Boot loaded at 0x03F was no longer being executed. The left side describes code modules and boot at91m9200, and the right side are physical memories with the installed or loaded indicated with arrows programs.

It keeps power consumption to a minimum under all conditions of use. I don’t know this device, but the datasheet says p.
Are you sure the remap even happens during this relocation? Also see this thread on AT91RM bootloaders to boot into u-boot.
