This provides low cost devices for small systems using the ARM CPU. This group is to exchange information to help users get started and learn how to use the devices.
AT91SAM9263 chip sect.... - Kiran - Jul 15 8:33:17 2009
Hi,
I am using AT91SAM9263 uController, uploaded with NAND_boot_strap & NAND_uBoot from "Linux4sam.org".
I am able to get "boot" prompt at hyper terminal.
After booting SD_CS is always LOW.
for this I am not able to select any other Chip_Select.
Is there any setting need to set at controller register?
Please help me.
Regards,
Kiran

RE: AT91SAM9263 chip sect.... - Microbit_P43000 - Jul 15 20:36:43 2009
Bit hard to tell from such little information.
As a guess, a few things to check on :
Do you have GPIO class enabled ? (guess so)
Do you have AT91_MMC enabled ?
If so, do you have the proper SCSI options turned on in Kernel config ?
It sounds like MMC/SD is somehow not enabled, and therefore the CS stays Lo=
w.
