Web UI to reboot to another partition (for Linksys/ZyXEL dual-partition routers) and to power off/power down

Jruuu · July 22, 2024, 2:18pm

Hello, the process is exactly the same as for my older WRT3200acm. First, determine the current partition number(1 or 2) with command:

/usr/sbin/fw_printenv -n boot_part

Then boot to the opposite partition number:

/usr/sbin/fw_setenv boot_part 1 && reboot
or
/usr/sbin/fw_setenv boot_part 2 && reboot

If only these commands are needed, then it will be the same for the V2 version of the router as well.

Thanks for your prompt reply.

If these commands work, the luci app should work too. Can you check if there are labels on the partitions by running:

dd if="/dev/mtd21" bs=1 count=256
dd if="/dev/mtd22" bs=1 count=256
dd if="/dev/mtd23" bs=1 count=256
dd if="/dev/mtd24" bs=1 count=256

I keep forgetting if it should be kernel or rootfs which is queried for the labels, so please run all 4 commands.

PS. Maybe save the output with of=/tmp/mtdXX-file variable and open the output files in a hex editor to confirm exact location of the label if it exists there. My guess it would be after 32 bytes or 192 bytes.

This is a bit beyond my knowledge, so I am pasting what I see. I clicked on the "k" in the word "kernel" in images mtd21 and mtd23 so the address(0xA8) shows up on the bottom left. Hope it answers your question:

Thank you so much, you've done amazingly well, the luci-app-advanced-reboot 1.0.1-11 from my repository should support your router. If you use github and want to share your username, I'll be sure to mention it in the pull request I'm going to send to merge the code into OpenWrt repo after you can test it.

Jruuu · July 23, 2024, 2:56am

Thank you for guiding me through it. I am not a regular user of github and it shows... It took me a good 15 minutes to figure out what to download from there. No issues on the install. I was able to boot to the alternative partition twice without any issues:

Booting from NSS driver snapshot image to regular openwrt snapshot build(yes they both have the same kernel version) on partition # 1:

And then back to the NSS driver snapshot image from the regular openwrt snapshot on partition # 2:

Is there anything else I should check?

stangri · July 23, 2024, 7:36am

Could you please elaborate on the images you flashed? I'm guessing one of them is not an official OpenWrt, is it?

Jruuu · July 23, 2024, 1:57pm

This router is not supported in the stable releases yet, only the snapshot builds. Partition # 1 has an ordinary snapshot build put together with the firmware selector (SNAPSHOT r26971).

Partition # 2 is a community build, based off the snapshot builds:

stangri · July 23, 2024, 11:19pm

When booted into a community build, could you please capture the output of:

cat /etc/os-release

Thanks again for your prompt reply. At least the mystery of where does r0 come from is solved.

Hi,

I have a Linksys MX4200 V2. Is it possible to support this too?

For the MX4200v2 as well. The model is SPNMX42 and it's distributed by Community Fibre in the UK but it's the same hardware.

The process to switch partitions is the same as for v1. fw_setenv boot_part 1 && reboot takes you to kernel while fw_setenv boot_part 2 && reboot takes you to alt_kernel.

Thanks for the PR @innovara !

innovara · September 13, 2024, 2:30pm

@stangri is there any chance that you can push version 12 including support for the MX4200v2 to your repos?

stangri · September 16, 2024, 3:43pm

Just did, thank you for your contribution and reminder!

Unless you can find the commit for this device and it says otherwise, the only way to make it boot into B partition would be to set the failed boot count in the S_ENV partition to 3. Without access to device it's impossible for me to know how the failed boot count is stored there.

If you want to provide the S_ENV partition dumps after 1, 2 failed boots and once it's been erased, I can give the support a shot within a few weeks.

lytr · October 7, 2024, 9:04pm

Isn't it enough to change boot_part u-boot env to boot from the second partition?

Seraphin · October 7, 2024, 9:13pm

Thank you for your fast reply, stangri. I'm looking into how I can help.

If I unterstand correctly, you need a hexdump similar like innovara and Jruuu provided for their devices?

As you are talking about S_ENV I would need to do a hexdump for mtd3 in my case, after each reboot? Or would you need the kernel (mtd5) and alternative kernel (mtd7) like innovara did?

If that's the things you need, I'll take a look into it within the next few days. Otherwise any hint what I have to look into is much appreciated.

lytr · October 7, 2024, 9:18pm

The entries in the S_ENV partition look like this:
