Also my version comes with some "tools" (I have no clue > which). 0.90 U-Boot version does not include the SD card voltage fix. You should try the update procedure pointed by Christer. It is done with a script utility that I wrote. Although, several prerequisites are required: 1) The SPI flash has to be accessible via the MTD framework 2) Tools: diff, grep, sed, hexdump, dd, flash_erase. The Ubuntu image and Linux kernel released by Compulab meet the requirements above, so can be used for the U-Boot update procedure. The update can also be done from U-Boot console, but has more place for a mistake. You can always contact me if you have problems with the update. Good luck! > > -Michael > > P.S.
