Aqara P3 UART TTL and power pins #57

I just missed flash a wrong firmware into Aqara P3. Now the device doesn't boot anymore. I opened the case but the UART pins are n't labeled. Could someone share the UART and power pins position ? I want to try flash firmware by xmodem into P3. Thanks. image

I don't have one so can't help you much. Just though of mentioning if you lookup the MCU schematics and with the help of a multimeter you should be able to narrow it down. Or just wait for someone to come and help ¯_(ツ)_/¯

Thanks. I've found the GND/Power and Tx pin. Not sure about the Rx because the device stuck in boot loop and is not responding to key input. Baudrate is 38400. image

And it seems there is no option in aqaragateway tool for Aqara P3 gateway. Is there any other way I can flash the FW into the gateway? image

Can you provide the log that can not boot up?

Please see the attachment for the full log. I flashed a Xiaomi gateway 3 firmware into P3 by mistake. Seems there is even no way to get into uboot? full_log.txt

You can flash P3 firmware by choose M1S model.
