rmilecki:

I've tried two images:

• openwrt-18.06.0-rc1-brcm47xx-generic-standard-squashfs.trx
• openwrt-18.06.0-rc1-brcm47xx-mips74k-standard-squashfs.trx

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.

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:
sh /rom/etc/uci-defaults/09_fix_crc
? What the output of above command?

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:

• 69ea512 ("build: do not alter global default package selection from profiles") (master)
• b84a1c5 ("build: do not alter global default package selection from profiles") (openwrt-18.06)

For the issue with 18.06-rc2 not booting please use a separated report.
