Part Number: PROCESSOR-SDK-AM335X
Tool/software: Linux
Good time of day, dear All :)
I have a problem with custom board, based on AM335x.
One year ago I used TI Linux, kernel version 3.19 and it worked perfectly. In this year I want to use Ti Linux with Kernel 4.4.
I rebuilt new kernel and device tree and cannot boot it :) Device silently hangs. Here is u-boot log:
U-Boot SPL 2015.04-rc1-dirty (Jun 25 2015 - 18:09:55) Trying to init board (board.c/am33xx_spl_board_init).

That`s all. I user hardware UART as serial terminal. It worked perfectly year ago in 3.19 and doesn't work now in 4.4.
