U-Boot w/ MMC/SD-card booting for Pogoplug Series 4 (3 replies)

Hello all.

I have succesfully installed U-boot on a Pogoplug Series v4 device and I am getting a strange behaviour.

I have installed the rootfs in a SD card but if I boot the Pogo unit with the SD card inserted, then the boot fails (no USB or other boot device is connected at the time I boot the device).

If I boot the Pogo without the SD card inserted, wait a few seconds, and when the led turns on blinking green I insert back the SD card then it boots flawlessly. Actually, I can perform reboots and the device keeps working correctly.

The problem I have is when a power outage pops up in the neighbourhood. The Pogo unit cannot get up again if I don't manually remove the SD card, which can be annoying when I am out.

I have tried playing with the uEnv.txt file but without success. Any clue will be appreciated.

Thanks!
