I've Just started playing with the MTD drivers for linux and I have a couple of questions. I am currently working on a project that (will) store the linux kernel/os on flash. We are useing the ElanSC400 chip and a board that has 3 pairs of AM29F016EC Flash Chips arranged such that the high byte of the data goes to one chip and the low byte goes to the other. I was wondering if the MTD supports this? These chips are JEDEC compatiable. Also I wrote a test program that run in user space and I tried using mmap() to read the device and it seems to work OK as long as I map /dev/mem as MAP_PRIVATE. I would like to be able to write to Memory < 1M directly. If I change the flage to MAP_SHARED, mmap() falied with "Permision denied" Any ideas?
