Re: [OpenWrt-Devel] Firstboot problems
Hi,
I had a similar problem on the BT Home Hub 2B, which also
has nand flash. The problem as you say seems to be that
mount_root assume that the deadc0de will be at the start
of the block where it would be for nor flash. I expect others
will have a better idea of the right way to solve this (perhaps
avoiding using squashfs on nand completely) but for the moment
I have I got round the problem by patching ubox mount_root.c
as follows.
I have also had to add to modify include/image.mk, adding 16K
(which is the erase block size on the HH2B) to the call to padjffs2.

Re: [OpenWrt-Devel] Firstboot problems
I think I found out the cause. The partition rootfs data gets created after the squashfs one at 0x73 in my case, but there there's the sercomm signature and checksum needed for the bootloader there, and the deadc0de jffs2 magic is instead at 0x74, and that's where the partition should start actually. Any suggestion? -- Marcus905 GPG pubkey: http://pgp.mit.edu:11371/pks/lookup?op=getsearch=0x1FC0ECC932FE5FAC ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
