[U-Boot] Sequoia board and U-boot

[Sergio Navarrez]

Dear all:



I?m working with AMCC Sequioa board. Nor and Nand memories was erased, and
I?m trying to program the Nand flash with the last u-boot version via
debugger. I followed the respective steps from your manual and compiled
u-boot with ELDK. But u-boot doesn?t work.



What can I do, to solve this problem?


Thanks,

Sergio Navarrez

You can only program NOR flash via the JTAG debugger. At least the 
BDI2000/3000 doesn't support NAND flash programming. So you either need to 
program U-Boot into NOR flash (target sequoia) or use the RAM booting Sequoia 
image (target sequoia_ramboot). And then use U-Boot itself to program the NAND 
booting image (target sequoia_nand) into NAND.

Cheers,
Stefan
