Was a hardware problem...
dmesg won't show anything .. We know that the file get corrupted because 
why try to exctract the jar file and get an error like (not a valid 
zip/jar file)..

Since we use SoMs, we test the same module(the little board) on another 
hardware (the official development kit) and it works without problems.

Since is not broken, but out of specification.. it works for some time 
then starts to do bad things...

I enabled mmc debug, got a lot of output but no error.. bad CRC or 
something like that.. I think that configuration (since is for embedded 
system) is too silent..

Thanks
Cheers!
