the Wandboard Quad

[Junhwa Rhee]

hello?

last year I received the Wandboard Quad I ordered from the future
electronics. (so far I have not ever used the board Unfortunately).

but even with the lot of Bootable Sdcard Images from the wandboard wiki
I cannot bring the board up and running with a suitable OS.

If the board is powered I see the two green "power" leds of the carrier
and cpu card And the red led inside the spdif.

the wandboard USB OTG show the following on the host system:

u-boot$ lsusb | grep Freescale
Bus 001 Device 059: ID 15a2:0054 Freescale Semiconductor, Inc. i.MX6Q
SystemOnChip in RecoveryMode

according to i.MX6DQ RM, "The boot code performs hardware
initialization, loads the Program Image from the chosen boot device,
performs image validation using the HAB library, and then jumps to an
address derived from the Program Image. If any error occurs during
internal boot, the boot code jumps to the Serial Downloader."

anyway, in my wandboard quad the boot code can NOT load u-boot image
from SD card(0x400) and No serial console output seen so far. so just
the boot code jumps to the Serial Downloader.

Whatever I try, changing SD card, power supply, serial cables, etc.

I do not see any response on the serial console using the stock images
from the wandboard download page.

now what should I do?

Regard,
JR

I am using Wandboard Quad C1.

It looks like you have bricked your wandboard. Try following these instructions to reflash the serial EEPROM:

Hope that helps,

Hi Sander, Thank you for your quick reply.

I tried to check it but not a good result.

Junhwa,

Please read the comments on the page I sent you. There are newer branches of u-boot that you should try, specifically for wandboard quad. Make sure that you load the correct u-boot and pull out the SD card while uploading the new boot loader.
