    can you try to reset the BIOS completely? Just unplug the RTC battery for a couple of minutes and then boot your board again with the RTC battery connected.

    Also, if you go into BIOS -> Boot Menu -> can you see or select eMMC in any of the boot options available?

    Can you read the eMMC type you have on your board? Is it a Kingston or Hynix? What size?

    I left the board without power for one day but I didn’t disconnect the bios battery ,the next day it boot normally and worked as usual!!
    I didn’t want to involve the bios battery removal cause I don’t know if the bios is reset to factory version or it’s just make a settings reset!!As I have read in the upwiki to make updates to bios you need to install one version after the other you cannot jump directly to the last version ...that’s something complicated but whatever the board just with power off for one day came back to normal state!!In the day that happened I was testing on it an OpenCL code that I recently wrote I don’t know if there is some relation with the insident but I think there’s not!Is the first time it happens to me
    To a board to dissapear the emmc so I thought it’s gone,I hope that is not an issue to this specific board cause I’m going to use those boards to my project.

    Just for future reference, removing the battery only resets the BIOS-settings, not the BIOS itself.
