FS#1647 - Linksys E3000 soft-bricks after reboot/power-cycle with 18.06-rc1 #6634
Comments
rmilecki: I've tried two images:
on BCM4706 and BCM47186B0: everything worked as expected. I don't have E3000 or any device based on BCM4718A1. So we need either a crystal ball or a serial console log to debug/fix this problem. |
mamarley: I do have a USB serial converter hooked up to one of my units, but I accidentally dropped it a while back and broke one of the solder joints. I will see if I can make a temporary repair tonight and figure out what is going on. |
mamarley: Oh, and another bit of possibly-useful information: Under "Model" in LuCI where it would normally display "Linksys E3000" or something similar, on 18.06 it shows "Unknown". I also tried a trunk build, but that didn't work at all and the router is no longer accepting images over TFTP, so it looks like I am going to need to put a serial adapter on that one too. :( |
rmilecki: If you boot image for the first time, then ssh into it, can you execute: |
mamarley: Wait, nevermind, please ignore the closure request. The build actually didn't flash at all and it was still running an old LEDE trunk build. |
mamarley: OK, I have some more data now. When I try to execute that command on a freshly-flashed 18.06-rc1, it gives me an error message saying it couldn't find "mtd". I "opkg install"ed it and ran the command again. It succeeded the second time and the router was able to reboot successfully, indicating that the problem is missing packages in the provided image. In addition to "mtd", I also noticed that at least "dropbear" and "dnsmasq" were missing. I also tried with 18.06-rc2, and with that the e3000 fails to boot even the first time. The serial console output is:

rmilecki: Problem with missing mtd package (and so 09_fix_crc failing) in generic subtarget builds has been fixed by:
For the issue with 18.06-rc2 not booting please use a separated report. |
mamarley:
I recently got my old Linksys E3000 out of storage for a project and flashed 18.06-rc1 on it (initially by sysupgrading from a previous OpenWRT build (I forgot which, sorry)). It initially worked fine, but as soon as I tried to reboot it, it soft-bricked with the power LED flashing quickly and responding to pings with a TTL of 100 on 192.168.1.1. I was able to TFTP 18.06-rc1 again and it successfully flashed and booted, but once again, attempting to reboot it either by power-cycling or a software-commanded reboot caused it to soft-brick. I then tried TFTPing 17.05, which was successful and worked as it should, including reboots. I once again tried upgrading to 18.06-rc1 and the soft-brick happened yet again.
Sadly, one of the wires broke on my serial adapter and I don't have my soldering iron to fix it right now so I can't retrieve the boot messages at the moment.
