[U-Boot] Boot failure with a AT91RM9200 based custom board
Greetings,
I'm looking for a AT91RM9200 specialist as I've got stuck porting board support from a old u-boot (v1.1.4) to the latest stable (v2016.07)...
I'm using the at91r9200ek board as a template to get things running...
With the patches i can get to the state below and here the board hangs. When patch 0004 is omitted, it seems the board doesn't boot at all (I'm basing this assumption on the current consumption of the system).
The console shows the following... initcall: 1001cce0

Any ideas, pointers, even flame is appreciated. If more info is needed I'm happy to deliver Thanx in advance. Cheers, Peter

I haven't booted that board for a while ...

AFAIR the address 0x0 is mapped to the boot source until REMAP (also depending on the BMS setting). It may be flash for your setup ... writing the flash with a copy instruction should fail so this could be the cause why it is not working.

Could you please check, if the RAM initialisation is working properly? AFAIR there was some problem with the u-boot RAM initialisation for this board but never fixed (shame on me). Some set of known data and read back before relocation should do the check.
