I compiled the latest 19.07.4 OpenWrt for the TPLink TL-WDR3600 and the build appears to have finished with no errors. I did not make any changes to the default menuconfig except setting the below:
Target System (Atheros AR7xxx/AR9xxx)
Target Profile (TP-LINK TL-WDR3600 v1)
A squashfs factory and upgrade images were generated in the the directory bin/targets/ar71xx/generic/.
When I upload either of the bin files through Luci it shows two errors:
Image metadata not found. Use sysupgrade -F ...
The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.
The factory and upgrade bin files built are parsed as 7.75mb and 4.25mb by Luci.
Does this mean the image did not build correctly or is this a normal thing for self-built images? Thanks.
