Hi -
Panda Testing update:
Booting on panda seems to be fine but sd/mmc dumps lot of I/O errors on console. Tested with device tree enabled and disabled. With device tree enable, the MMC I/O errors are more. Tried with multiple SD cards with different brands.
Not sure if there is any bug already listed for this issue.
## Flattened Device Tree blob at 81600000
Booting using the fdt blob at 0x81600000 Loading Kernel Image ... OK
Not using DT but...
it happens without DT also
[ 5.139984] mmcblk0: mmc0:c71c SD01G 982 MiB
[ 5.146911] mmcblk0: retrying using single block read [ 5.147186] mmcblk0: error -84 transferring data, sector 0, nr 8, card status 0x900
...not seeing this at all on an 8GB class 4 microSDHC, brand "Veho" I am using.
Tried with Sandisk SDHC Card 4GB(class 4) but with this card, it fails to load kernel image from SD to RAM

Is your card really 1GB SD Card? Were any of the other cards SDHC?
yeah...it's Kingston 1GB card. I have only two cards with me now. I can try with some other cards also.
