Hi, Im using a AT91 processor on a AT91RM9200DK board. Im using a port that someone in my company did some years ago. Here is my problem: I would like to use the graphic possibilities of the board. In the development kit, I have an example driver (source code and bin file).
If I run the bin file from Zooboot it works fine. If I build the driver (using arm-elf-gcc) and launch it from Redboot (using eCos environment) it doesnt work anymore. Ive traced down the problem to the chip select line 2 (NCS2). This chip select should be enable when I access data at 0x30000000 but its not. I was thinking that it might be a problem with the MMU initialization that is done in eCos in AT91 common code. Do you have any idea what Im doing wrong ?
