Good day! I'm working with MPC8349 CPU and Linux 2.6.11. I'd like to get access from user application to FLASH MTD device. I can open "/dev/mtd0" device, read, write, but I can't erase it! As far as I know I should use ioctl(fd, MEMERASE) system call to erase MTD device, but this call is failed - MEMERASE undeclared! Can anybody help me with it?

With my distribution of uCLinux I can create "erase" and "flash_eraseall" for that purpose.

I'd like to erase MTD device from C source code!

So you can either start the eraseall program e.g. with "system()" or include part of the sourcecode into your program.
