I am trying to see
if u-boot allows to have a single partition for both kernel and file system in
NAND Flash.
Currently, we have
one 4M partition for kernel and the rest of the NAND flash for file
system.
But, I am looking
for possible ways of upgrading the kernel in the field.
Currently, I am
looking at two possible approaches:
1. add an extra
partition in the NAND flash and keep the second kernel in there and have some
way in u-boot to decide which one to load.
2. if u-boot allows,
have one single partition for both kernel and file system and upload both kernel
images and have a soft link to a kernel image.
I can't find a way
to do the second option above, but that would be ideal for field upgrade.
Has anyone tried either of these approaches or have any other idea of how to do
this? I am new to using u-boot and linux.
Thanks
