Hi,
Here’s my story. I’ve moved from angstrom 2012 to angstrom 2013.12. Everything compiled fine and system was booting, using new Angstrom but I used my old Kernel. Then i’ve started to develop new kernel and i’ve based on the original. At the moment when i’m booting system everything looks fine but angstrom isn’t startring. The best way to describe it is to show your my log. This is full log - obtained using Serial port. Nothing more came, and system stuck!
I’ve only changed board-am335x.c file. My changes are attached.
ps. Sorry for my english.
`
Uncompressing Linux… done, booting the kernel.
