Samples are planned from April You can prove this for yourself by single stepping through the code. It provides the performance to run, simultaneously, RSA encryption, secure keypad control and a V.

According to the boot overview p. The ARMT core takes us into new territory where performance, connectivity and security are paramount. There is no hardware remapping going on here.
Sign up or log in Sign up using Google. The internal ROM contains proprietary Atmel code that is not published. I don’t know this device, but the datasheet says p. Can anyone please help me understand the remap operation in u-boot and show me the code corresponding to this? However I’m unable to figure out where the memory remap operation is happening in the code.
There’s also mention of an “atmel appnote” apparently about AT91RM bootstrap, but I cannot find it at the Atmel site. It keeps power consumption to a minimum under all conditions of use. 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.
Are you sure the remap even happens during this relocation? Also see this thread on AT91RM bootloaders to boot into u-boot.
