Hi, Can anybody tell me as to how can I access the memory mapped registers directly? I have a linux kernal image sitting on my board and every time I try to access the registers directly, it gives me segmentation fault. I use the below command. *(unsigned int *)(0x01c67038)=0x4F4; Even though it compiles fine, when I run the executable, it gives me segmentation fault. Note the above works fine when I run it using JTAG because there is no Kernal image on the board. I also have some drivers to set the registers but those make my code very slow and it does not meet the timing requirements. I was wondering if anybody knows how to set or read registers in a fast manner with the Kernal image present on the board. Thanks, -Furqan
