ok, I am working on hhl's 2.2.14. I enabled: Support for frame buffer devices (EXPERIMENTAL) RPX-Lite 823(e) LCD Frame Buffer when I configured the kernel.
I am sure the lcd is configured correctly because I clear the screen by setting the memory mapped to lcd's framebuffer to all zero after lcd823_init_dev(). but nothing happened when the kernel boot, nothing displayed on the lcd. I found lcd823_init() calls register_framebuffer() to do the registration, and the console should be switched to frame buffer after register_framebuffer call take_over_console(). but why there is no char displayed? any suggestion? btw: do I have to enable "Advanced low level driver options"? the help file says the low level drivers are automatically enabled. thx Alan ** Sent via the linuxppc-embedded mail list.
