Hi Marcio:
Do you run uClinux on flash directly? not use bootloader to move the
kernel to the RAM? If you run uClinux on flash, I think you could not
update the kernel..
If you run the kernel in RAM,please remove READ_ONLY attribute of thoese
sectors first.(check your Toshiba TC58FVM7B2AFT65 flash datasheet first).
Best Regards

Hi Marcio,
maybe you can show us the kernel boot log to see if MTD recognized the
flash, and how you tried to write to the flash.
