[meta-freescale] Regarding " fb memory is not big enough to hold shadow buffer!"

[abhishek sharma]

Hi All,


I am new to this community. I am trying to test the fbdev fallback option
on the wandboard. I am recieving the error "fb memory is not big enough to
hold shadow buffer!" Please let me know If i am missing something. I tried
to increase the fbmem using kernel command line but it did not worked.

Please find the complete logs below:
