To add:

Expect OpenRD support in mainline in next 2 weeks.

Greetings,

Mainline kernel for OpenRD is in the works.  Your attempt to build latest kernel with sheevaplug or rd88f6281.c file will not work.

- Dhaval

If u-boot on NAND is programmed using OpenOCD (which is true during production), you will see NAND: NAND ECC error as OpenOCD somehow doesn't support flashing u-boot with ECC support; thus, 88F6281 SoC BootROM reads u-boot without ECC support.

Easier way to fix this issue - re-write u-boot on NAND using u-boot.  This can be done using

Marvell>> setenv ipaddr <ipaddress>
Marvell>> setenv netmask <subnet mask>
Marvell>> setenv serverip <serverip having tftp support>
Marvell>> bubt <uboot.bin file>
Marvell>> reset

Now, you should see no NAND error message during u-boot boot up, only if run_diag env is set to yes. 

SD on your SheevaPlug seems dead; you will need to report this issue to GlobalScale.

- Dhaval

Stock kernel shipped with SheevaPlug supports SD i.e. SD driver is built-in to the kernel.  Can you post your kernel boot up log and output of following command:

cat /proc/partitions

Please make sure that SD card is inserted into SD connector while you boot up kernel.
