Armadeus Framebuffer documentation page !
Here is the procedure to have a working framebuffer on the board (beware it's tricky for the moment !!, but it's for people who can't wait ;-))
- comment lines number 427 & 438 in linux/drivers/video/imxfb.c (PD11,PD12 config)
- merge attached scb9328.c file with linux/arc/arm/mach-imx/scb9328.c
configure the linux kernel for Framebuffer support:
- in "Char Devices" menu, activate "Virtual Terminal" and "Support for virtual terminal on console"
- in "Graphic support" activate "Support for Framebuffer", "Motorola iMX
LCD support" "Console display driver support ->Frame buffer console support" (deactivate VGA stuff & add some fonts), then choose 224 colour boot logo
recompile the kernel, now to have console on serial port, you will have to add "console=ttySMX0,115200n8" to your boot parameters
load image on your board and enjoy (you should see linux logo on screen at startup)!
If you have devfs activated, framebuffer device can be accessed with /dev/fb/0. Otherwise, you will neede to create the device node with
mknod c 29 0
You can activate some test tools from the armadeus build process:
make menuconfig -> packages -> fbset
You have several test tools on yahoo groups to play a little with the framebuffer.
