Hello,

Anybody has already boot linux from a dataflash card? I have the at91rm9200dk and it has a dataflash card socket that I can use.

Do I have to write a function in u-boot in order to copy kernel and ramdisk data from the smartcard to the sdram memory?

And also a function to copy kernel and ramdisk data into the dataflash card.

Best regards

Ok I enable CFG_CMD_NAND flag in the config file and when I compile the source code, I got these errors :

cmd_nand.c: AT91C_PIOC_PDSR undeclared
...
and so on.

How can I fix this problem? Just include the good header file?

Regards

Christian

I strongly recommend to read the README before posting. In this case the section "DataFlash Support" might be interesting to you.
