I have fixed it now. This was my scenario. I have two BBB boards, running the same OS image, and a uSD card with that same OS image. All runned fined, until I did something wrong with one of them and it bricked. It wasn't able to boot from either the eMMC nor the uSD, the other BBB board booted though.
The bricked BBB wasn't able to even boot, uboot wasn't loaded, by writing the 'C' character continuously. With the flasher image loaded in another uSD it booted, but the kernel was crashing. So, finally, I booted the bricked BBB with the flasher image uSD until it displayed '*Hit any key to stop autoboot*', the I swapped the flasher image uSD with my OS image uSD, and it finally booted it. Then I reflashed it and the BBB came back to life. So I guess that uboot was broken in the bricked BBB.
