Changing the bootargs so that NFS boot includes fbdev

I spent a week trying to get the display driver , fbdev, to run on the c6a816x EVM board, and it turned out that I needed to include the video memory settings in the NFS bootargs.  In the interest of sharing this with the community, here are the necessary settings.

 

Fixed IP

setenv bootargs 'console=ttyS2,115200n8 rw mem=166M earlyprintk vram=50M ti816xfb.vram=0:16M,1:16M,2:6M root=/dev/nfs nfsroot=192.168.1.100:/home/lholeva/targetfs,nolock ip=192.168.1.10:192.168.1.100: 192.168.1.100:255.255.255.0:c6a8168:eth0:off'

setenv bootcmd 'tftp 0x81000000 uImage-c6a816x-evm.bin;bootm'

 

 

DHCP

setenv bootargs 'console=ttyS2,115200n8 rw mem=166M earlyprintk vram=50M ti816xfb.vram=0:16M,1:16M,2:6M root=/dev/nfs nfsroot=192.168.1.100:/home/lholeva/targetfs,nolock ip=dhcp'

 

setenv bootcmd 'tftp 0x81000000 uImage-c6a816x-evm.bin;bootm'

 

My thanks to Ian Byers for telling me of this.
