Hi,

we've gotten reports that Gluon 2016.1 doesn't boot on TL-WR841 v5. I've already found out that one of our patches on top of OpenWrt CC is the culprit (probably one of the backports from the OpenWrt trunk).

Unfortunately, I don't have such a device to test, so if you do and and are able to connect it to a serial console, getting logs of the crash would be highly appreciated. I suspect the issue might also be reproducible on the TL-WR741 v1/v2, TL-WR743 v1 and TL-WR941 v4, as the hardware is very similar.

I got a TL-WR841 v5 device from Jens and I could got an serial dump. The image is our v0.8 image based on gluon v2016.1.x 55dc9c369d763f4b359070b2628efe46d983e0ec Should I try that experimental image from you? -- Tarek 1. start tata@keks ~ % picocom -b 115200 /dev/ttyUSB0 picocom v2.1 port is : /dev/ttyUSB0 flowcontrol : none baudrate is : 115200 parity is : none databits are : 8 stopbits are : 1 escape is : C-a local echo is : no noinit is : no noreset is : no nolock is : no send_cmd is : sz -vv receive_cmd is : rz -vv -E imap is : omap is : emap is : crcrlf,delbs, Type [C-a] [C-h] to see available commands Terminal ready U-Boot 1.1.4 (Nov 16 2009 - 09:06:24) AP93 (ar7240) U-boot DRAM: sri #### TAP VALUE 1 = 8, 2 = 8 32 MB id read 0x100000ff flash size 4194304, sector count = 64 Flash: 4 MB Using default environment In: serial Out: serial Err: serial Net: ag7240_enet_initialize...
