Re: [U-Boot-Users] Suggestion on CRCing data on NAND?

Here's what I need to do from u-boot. I'd like to check the validity of rootfs before launching Linux kernel. NFS is not available for what I'm doing so if the rootfs is corrupted, the kernel will just panic and hang there. We can't use boot disk, etc. either. So, I'd like to check rootfs and if it seems corrupted, u-boot will download the valid rootfs image (via tftp) and burn it on flash before it launches kernel.

I'm planning on making the rootfs read-only so that CRC checking make sense for this purpose. If there's anything we need to save, we will just save them in a flash in a separate partition.

OK, understood. Sounds OK.
