Hello,
(It?s about the AT91SAM9260EK)
I want to locate the U-Boot and the U-Boot enviroment in NAND-Flash.
AT91Bootstrap at 0x00000000
U-Boot at 0x00020000
U-Boot Env at 0x00060000
U-BootEnv_Redund at 0x00080000
U-Boot Env Size is 0x 00020000
When U-Boot starts:
.
.(NAND and DATAFLASH is initialized)
.
***Warning - bad CRC or NAND, using default enviroment
How could I "activate" the enviroment variables located in NAND flash at
address 0x00060000 ?
please help
thanks very very much
Best regards
Manuel Sahm

This will require a new board support option.
Have a look at http://www.linux4sam.org/ for more info on NAND support.
Integrate with buildroot and send a patch.
