Hi all,
I am trying upgrade the kernel of a board to mainline kernel (4.7.4)
and I'm having difficulties with the booting procedure after the upgrade.
This board hasn't a dts file available in the kernel, I had to write
one and I believe this is the likely source of the problem.
The board actually boots but it is not mounting the root partition (it
is an eMMC, /dev/mmcblk0p7). After some messages sent over the serial line,
the kernel disables some board power sources and stops sending data.
Probably there are more messages to be sent.
Anyone knows what's wrong? The board works flawlessly with an older
kernel (3.3.0) and the older tools provided by the people that developed
this board.
Thank you in advance,
Marcos
