WAVGAT UNO R3 #51

Closed mamejay closed 2 years ago

mamejay commented 3 years ago

This is a silly question. I accidentally purchased WAVGAT UNO R3 not realizing that they are not a direct clone. I have tried to write the eeprom_writer.hex to the UNO and now its stuck in a loop failing on verify. I cannot reflash any other firmware to the UNO as I get time out issues opening the port. Any idea if I can make these usable with a SDRive Max and if possible how to recover the boot loop I have on it.

Thanks

I have about 20 of these UNOs and up till now couldn't find a way to flash them. Better get a proper atmega 328p clone

I ended up desoldering the clone 328 chips and soldering in real ones. Reflashed using another UNO that worked and now they all work corectly.

You have could used an ISP flash adapter instead.
