Support for TP-LINK TL-ER6020 V1

Hi guys, I need your help. I have a TP-LINK TL-ER6020 V1 router. I can not flash it on openwrt, because there is no firmware. Is it possible to create firmware for this model?

Might be, if you create that...

Based on quick googling, the TP-LINK TL-ER6020 device (without wifi?) runs a Cavium CNS3411 600 MHz CPU. Right?

Really rare processor, and there is currently support just for one device using that CNS3xxx processor family.Based on target Makefile, @xback is the maintainer for the target.
https://downloads.openwrt.org/snapshots/targets/cns3xxx/generic/

But the whole target is rather dormant:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=tree;f=target/linux/cns3xxx;h=13ed4c11fc59da7493c805fa380b87df8fe69aa8;hb=HEAD

Not very likely that anybody would author the firmware for that device (as it requires live testing with device).

Thanks for the answer. I made the firmware for the cns3xxx / generic target. But the bootloader is locked. Unfortunately, my knowledge is not enough to understand this. But I will try.

Could you share uart logs of the bootloader and the boot process?

Could you describe what you mean with "locked"?

Thanks.

Greetings. I mean, I can not flash through the web interface. Through the console too. The bin firmware file could not be loaded (not suitable).
I do not know how to connect to the UART, because I do not know where it is on the board.
