I also tried to delete those partitions as described in the link. That did not solve the problem.
I have openwrt 23.05-SNAPSHOT installed and tried to revert to WAX220-V188.8.131.52.img or WAX220-V184.108.40.206.img.
Prior to flashing Openwrt the firmware was WAX220-V220.127.116.11.img if i remember well.
i started a couple of weeks ago with the snapshot factory.img from the WAX220 wiki page and then loading a custom build of 23.05.0-rc3 from the firmware selector. that worked ok but i had some stability issues with a week of uptime.
i switched back to the OEM firmware to see if it gave better stability but just found i ended up with different problems.
so, i switched back again to openwrt and this time went with the r24002-e3559fb445 snapshot from yesterday and it has been good so far - will see in a week or so if the stability continues.
i've only been able to get the 5G radio to work with auto channel selection so if you need specific channels this may be problematic right now.
@Flole thank you. I do not know how to get connected to the serial interface and which hardware is required for WAX220 case.
Can you please guide me (as a noob) with hardware and software (MacOs) steps please?
@aicjofs , @falstaff, it seems you had an issue with nmrpflash in the past. Please help me to recover this unit based on your past experience - such instruction will be beneficial to put at wax220 page that will help anyone in a situation like I ended after flashing
@glazeus There isn't really much you can do at this point, you are working blind. You need a serial(console output) connection.
If you don't know much about this it's best to read some and watch some videos but basically
Need a USB to TTL adapter(set to 3.3V)
Pins, solder, and cables to connect the WAX and adapter
As I recall for this unit:
-don't connect the WAX VCC to the adapter
-adapter GND to a ground pad on WAX
Serial software if using Windows(putty, etc)
-115200, 8N1, 3.3V
As for nmrpflash... I can't remember what the error said but it would start the download and then give the error. No way around that until I erased UBI partition. Even then the first reboot the console gave the same error. I rebooted an immediately started nmrpflash and it loaded fine.
