I'm working on LayerScape LS1021ATWR facing difficulties in enabling the DCU/HDMI on the LS1 kernel. Following is my configuration info
U-boot: Bank0: Normal u-boot
Bank1: Lpuart u-boot
RCW: Bank0: RSR_PPS_70/rcw_1000.bin
Switch Settings: SW2: 10000111
Jumper Settings: J19-20: 1-2
Filesystem: Graphical image
bootargs=console=ttyLP0,115200 hdmi root=/dev/nfs nfspath=<path to rootfs> rootwait rw ip=dhcp video="fslfb:640x480-32@60,monitor=hdmi"
I'm trying to boot the kernel from the bank1 where in u-boot is configured for lpuart and rcw is also for dcu (I have also verified with rcw_1000_lpuart.bin in bank1). Im booting via NFS, since booting via sdcard while testing hangs the board. I wanted to know if i'm missing something in the bootargs, I have verified that all the modules required for dcu are compiled built-in and required dts information is also present. could you please help in enabling the HDMI in kernel while booting from bank1.
