Hello all, First the status : * The fbd has been ported and it's attaching with the fb0 devie. There's an fb0 device entry created. * In the following commit I have added mmap to libbsd. This works like a wrapper to the mmap in cpukit : https://github.com/thelunatic/rtems-libbsd/commit/a8fc3b2b6840465029a000cc4169e9efbd551097
Blocker : * After the fb0 is created and mmap is added, I don't see anything on the screen. From the FreeBSD, it seemed like the VT driver is needed and that is responsible for turning on the screen. So I have ported a minimal version of the VT with only the initialization and allocate parts: https://github.com/thelunatic/rtems-libbsd/commit/95279e116717973525b581ae2e9550d1d3b8e1ba But even after porting the VT driver which initializes well ( As the message during booting says). I don't see anything on the screen. I need some ideas on what is missing or how to debug this. The app I'm using to test framebuffer is pushed here : https://github.com/thelunatic/rtems-bbb/tree/master/apps/fb-sample Any idea regarding this is greatly appreciated. Thanks, Vijay
