arm – Relocating U-Boot from internal ROM to SRAM on AT91RM – Stack Overflow
It keeps power consumption to a minimum under all conditions of use. Atmel designs, manufactures and markets worldwide, advanced logic, mixed-signal, nonvolatile memory and RF semiconductors.

Can anyone please help me understand the remap operation in u-boot and show me the code corresponding to this?
Also see this thread on AT91RM bootloaders to boot into u-boot. I found a duplicate image at91rm92000 U-Boot at 0x07F Performing a mtest 0x 0x07F tested and overwrote all but the highest megabyte at19rm9200 RAM, and proved that the U-Boot loaded at 0x03F was no longer being executed.
I don’t know this device, but the datasheet says p. Are you sure the remap even happens during this relocation? Examples include telematics systems connecting GPS receivers and GPRS communications, industrial at1rm9200, medical systems and point-of-sales terminals.

It targets applications requiring enhanced performance such as host processors for system control and connectivity. 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. There’s also mention of an “atmel ay91rm9200 apparently about AT91RM bootstrap, but I cannot find it at the Atmel site. A sophisticated power management controller provides a range of clock speeds and enables individual peripherals to be powered down when not in use.

According to the boot overview p. That code doesn’t tell us anything without any actual values for all the addresses involved.

It builds on our at911rm9200 and partnerships established with ARM7-based systems, notably with our qualified third-party development tools supplier, Green Hills Software. Samples are planned from April The ARMT core takes us into new territory where performance, connectivity and security are paramount.
There is no hardware remapping going on here. It provides the performance to run, simultaneously, RSA encryption, secure keypad control and a V.
