Hi!
I was using Sheevaplug booting from a SD (Ultimate SDHC Class 6 8GB) without any kind of problem for 5 months. Recently Sheevaplugs starts rebooting frequently and finally it died of psu failure (the famous one). I opened it, remove the old one and conect an external power supply of 2A and 5v. After that when Sheevaplug tries to boot I get the following error: "No MMC card found". mmcinit fails with that error!

After that I taked the SD card and get into my desktop and it works! the card can be read without problems! So, I backup it formatted it and tried to reinstall Debian but again the same failure in the mmcinit. I had reinstalled all the sheevaplug with the unbricking procedure (with Ubuntu jaunty after a few minutes I get segmentation fault but after that it seems that Sheevaplug is reinstalled ok) and after that again the same error of mmcinit.
My uboot version is "3.4.27-pingo". In the jtag message appears 3.4.27 but when I execute "version" I get "3.4.27-pingo".
I tried to install into a USB but in the middle of the process sheevaplug suddenly restarts!
Is my sheevaplug physically damaged?
