I tried to install OpenWrt 19.07.0 on TL-WR703N. After flashing, the LED blinks very quickly and from the looks of it, it enters the failsafe mode. I tried to connect it via ethernet, but I cannot find it at 192.168.1.1.
My WR703N has been modded with 16/64, I don't know whether this causes the problem.
Has the mod worked? Other than that in the device page it shows 17.01.7 as current supported release.
The mod works. I have tried both 17.01.7 (official) and 18.06.5 (self-built from source code).
The device page confuses me as well as there is image for it in the official release.
At least for the ath79 target, you need to adapt the DTS for your changes - ar71xx is doing a little more autodetection in terms of RAM and flash (depending on the OEM bootloader's capabilities).
I have tried to modify ar9331_tplink_tl-wr703n_tl-mr10u.dtsi and change the partition according to 17.01 dmesg output, it still fails (the LED blinks very quickly just like before).
Is there anything else should I modify?
There's likely valuable clues on the serial port.
Try to build a second time and it works. Maybe I did something wrong on the first run.
A few days ago I did the 64MB RAM mod, and since the router is still functional after the operation I'd like to continue with the flash upgrade. The precondition for that is having a custom firmware, but I doubt the ones I managed to build on branch 'openwrt-19.07' are fine:
-rw-r--r-- 1 gep gep 3342340 jan 25 15:05 bin/targets/ar71xx/tiny/openwrt-ar71xx-tiny-tl-wr703n-v1-squashfs-sysupgrade.bin

The first problem is that it is smaller than expected, http://downloads.openwrt.org/releases/17.01.7/targets/ar71xx/generic/openwrt-17.01.7-ar71xx-generic-tl-wr703n-v1-squashfs-sysupgrade.bin is bigger (3520.0 KB).
My other problem is that the size of the built images didn't really grow after adding stuff to configuration with make menuconfig.
All I found on this branch regarding the 4MB -> 16MB mod for WR703N was this, seems like some proper single point of responsibility to me:

In the ath79 .mk file

is suspicious too.
Any thoughts or advices what could have gone wrong?
Possibly @Icarusradio could share its config.seed and git diff?
Thanks in advance.
Asked for help too quickly, as usually.
For the ath79 I've just overlooked the answer on tweaking DTS.
For ar71xx I have no answers yet, but since I did a distclean I'm only some aeons away from a success/failure update here.
Another place to -maybe, depending on your particular router and its partitioning type- look for would be the partitioning definitions in tools/firmware-utils/src/tplink-safeloader.c, but given that ar71xx is deprecated, ath79 is all you need.
An additional distclean and tweaking the DTS actually did the trick for ath79, no more dependencies seem to have been left:
