Writing to /dev/fb0

[Vijay Kumar Banerjee]

Hello everyone,

I'm working on porting the Framebuffer driver from FreeBSD to RTEMS
for BeagleboneBlack. I am in search of a sample/test application that
I can use to directly access the fb0 device and write something to it.

The purpose is to test the created fb0 device and work with it without
any heavy application like X. Something as minimalistic as:
`cat /dev/urandom > /dev/fb0`
But this doesn't work on the FreeBSD. Any suggestions on how to
test the fb0 device and how to write random pixels, or maybe draw a line?

Thanks in advance,
 Vijay
