Hi,
I am using u-boot/mtdparts to setup some partitions on
a NOR flash.
mtd0: 00080000 00020000 "uboot"
mtd1: 00180000 00020000 "kernel"
mtd2: 01e00000 00020000 "root"
In my mtdparts I specified the first 2 partitions as
read only.
mtdparts=phys_mapped_flash:512k(uboot)ro,1536k(kernel)ro,-(root)
We have run into a case where we need to write to mtd1
after Linux is already running and changing the boot
loader command line is not an option.
Is there a good way to do this?
Thanks in advance,
DT
