@igaran
Somebody get same error when they use their own compiled firmware.
Just download one from openwrt will fix this: http://downloads.openwrt.org/barrier_br ... ps/rt305x/

Found a error:

[ 0.490000] m25p80 spi32766.0: unrecognized JEDEC id ffffff

That is the problem ?

This seems to point on a wrong configured SPI flash. M25P80 is a specific SPI flash with a specific JEDEC IC (it will be read out from the program to check whether it is supported/there are drivers for in the program). According to BOM there is a W25Q64FVSTIM/G populated on the PCB, so you might want to adjust the configuration.

Strange, but ok.

Looking again on
Code: Select all
[ 0.490000] m25p80 spi32766.0: unrecognized JEDEC id ffffff


It also might say that the ID which had returned is FFFFF - this would mean that something in the spi communication went wrong.

So you just didn't do anything with it except trying to use it?

OK, that is odd. Normally i would suggest just claim that by the vendor - but in this particular case, i do not think it would help you. You might want to visit #openwrt on freenode-irc, they probably give more information what this problem means exactly - i am sorry that i cannot help you further!
I have a few VoCore (w/o dock) left here, if you are located in Europe it could be easier to get and you should not have to wait 4-6 weeks if you decide to get a new one.
