Hi folks, I have some basic problem: I have my uclinux currently running on Coldfire board from RAM. I have romfs as my file system but that is read only file system.I donot enable MTD support, blckmem is also disabled.
I enabled a RAM disk(CONFIG_BLK_DEV_RAM) and initrd(CONFIG_BLK_DEV_INITRD) and choose rootfs as my filesystem. Now I want to change my configuration so that I have a writable filesystem in RAM. I am confused with the configurations I need to set to choose a writable file system for uclinux running from RAM. What uclinux configuration I need to select to boot uclinux in RAM with writeable filesystem? I guess I donot need MTD because that is used for FLASH memory, Neither I need blckmen that is also for FLASH memory. I need to just create a block on RAM and just put a filesystem on that block. Please correct me if I am wrong. Please also proivde the reason which and why a particular configuration is enabled. What role the config is playing in writeable filesystem? Thanks a lot for replying
