Hi Angelo,
you have to enable the physmap driver, and specify start address and
length of your flash there. You have to enable MTD_JEDECPROBE for
non-CFI flash. For CFI-flash, you have to enable MTD_CFI_INTELEXT or
MTD_CF_AMDSTD, depending on the type of flash that you use. If it still
doesn't work, post your enabled kernel config options with *MTD* in the
name, and the flashchip that you use.
I am having similar issues to Angelo.
Does this mean it is not possible to have a root filesystem on romfs without
configuring MTD, MTD_BLKDEVS and maybe MTD_BLOCK (or MTD_BLOCK_RO)? Is there
somewhere else to mount the romfs?
My system executes from RAM with romfs following the kernel in typical
uClinux fashion. I only enable MTD at all so I can use char devices for
accessing flash from user programs.
Philip
