Support for TP-LINK RE305 V4

For Developers
1

Does anyone know if TP-LINK RE305 V4 is supported by OpenWrt? I tried to flash the firmware, which supposedly works on TP-LINK RE305 V3 via the web interface, but it is not uploading on my device.

Is it possible to upload it by other means (tftpd or serial)?

Which could indicate a 4mb flash, that's too small for openwrt anyway.

sadly I ended up buying (another) one without realizing its v4, did anyone successfully flashed it? am i correct my only path is using an older openwrt (e.g. 19.x) and compile myself? can anyone confirm which chipset is inside before i open it up? :slight_smile: thanks!

another RE305 v4 owner here. Couldn't find much info about flashing into v4.

I'd like to help to get support for RE305v4. I soldered USB-TTL cables into RE305v4. Somehow I got quite garbled output. The link is below. Any idea what could be wrong ?

What commands to look for in U-boot menu ? If the flash is only 4MB can OpenWRT be flashed ?

Thanks

The serial bit - looks like RX and TX are fine but I think you need to check the GND connection. I suspect it's either not connected or connected badly.

Possible, but not really recommended: https://openwrt.org/supported_devices/openwrt_on_432_devices

16Mb RAM and 4Mb flash.

16 MB RAM completely disqualifies it (4 MB flash already would have, but the RAM makes it -much- worse).

10

Ok, well that's it.

Is it worth to update wiki with this information for RE305 v4 that it is not for openwrt ?

probably because there isn't any.

12

the list of unsupported devices would be longer than the supported list.

13

True. Well, but at least then I would know it for sure. Now there was no information about flash or memory size before I found it out that it is no go for openwrt.

14

Your efforts didn’t go in vain. Next person with this device might try to search this forum and learn from your research.
