I Implemented the microblaze with the TFT controler ( PLBv46_tft_controler) that I adapted for plbV46. I m trying to use the the frame buffer to control it.
So I try to use teh xilinxfb driver fromm PPC but I have some problem to adapt it for microblaze. All compile, the TFT lives but I cannot see drive the console on it.
What I saw is that teh driver reserved an space of adresse and write it to the DRC inferface. But there is some Ioremap and for me I got a fix adress for the TFT_frame_buffer ( some pb with the DRC interface)
Anybody has already adapt this driver for microblaze ? Do you the change that I have to do to implement a fix address space ? How to drive the console on the TFT controler ?
PS : without linux my hardware works fine, I can drive the TFT display.
