On my AT91RM9200 board, I have an Atmel DataFlash for booting off my
SPI, and I have a NAND flash.
I do not, however, have any other kind of flash.
My 128K DataFlash address is 0xc0000000, and my 128MB of RAM is at
When I do
cp.b 20200000 c0000000 2c60
Copy to DataFlash... done
it works just fine.
When I do
cp.b c0000000 20200000 2c60
the system crashes with a data abort, but before the crash, it reports
Copy to Flash...
Well, I'm quite confused how to set the various flash flags to make all
If I try to set CFG_NO_FLASH, the system won't compile.
But there is no "conventional" flash on the board... just the nand
(8-bit port) and dataflash (spi).
Would someone kindly point me to a reference that explains how I can set
up u-boot 1.2.0 to make this work? Or just come straight out and tell
Thanks in advance,
