Platform : PC/104 with AMD Geode LX CPU with integrated graphics. Buildroot framework, kernel 4.18.10.
I am building a custom Linux system with Buildroot. Since I compiled the Geode LX frame buffer driver in the kernel (lxfb), I get a black screen on the flat panel (800x600 LCD), but the VGA output works.
It seems like the driver needs some input, but I can't figure out how to do it. See last struct : https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/video/geode/geodefb.h?h=linux-4.18.y&id=b5c26f97ec4a17c650055c83cfc1f2ee6d8818eb
Can anyone help me ?
