Comment (by lorenzen):
I think I have an even better solution.
Inspired by how they handled a similar problem with the wrt160nl (ticket
8960) I though I would just try a similar cure here.
and it works very well, adding just 17 lines and making 105 lines
redundant in the codebase. and now sysupgrade transfer of config files
works too.
Before the lzma-loader, linux-kernel, squashfs where encapsulated in an
uImage. which has a crc-check
The cure is to only encapsulate lzma-loader and linux-kernel in the uImage
and append squashfs and maybe files saved by sysupgrade to it
The best part is that we can remove the whole fixing of the crc in
driver/mtd/maps/adm8668.c since it will never be executed.
I have successfully installed a new systems both with u-boot
update_kernel, and sysupgrade.
Here are the necessary changes to target/linux/adm8668/image/Makefile
relative to r42162
I will update the https://dev.openwrt.org/ticket/14745 with full changes
shortly
for people wanting to use fw_printenv/fw_setenv on the uboot environment,
you need to do:
$ echo /dev/mtd3 0 0x400 0x2000 >/etc/fw_env.config
I have put that into my code base under target/linux/adm8668/base-
files/etc/fw_env.config
it would be nice if that would be part of the code-base too
I have uploaded a diff relative to r42162
