Sonoff Dual R2 not responding after successful flashing #897

Closed skyynet closed 5 years ago

skyynet commented 6 years ago

I successfully flashed one Electrodragon and some Sonoff Dual R1 boards with ESPurna 1.12.6. I also flashed two R2 boards with 1.12.6 and of course changed the configuration in arduino.h to the r2 setting. Unfortunately both boards do not blink or show a wifi ap after having them flashed. When the first board failed I thought I might have killed it but the second one also behaves the same.

Any idea?

Board not reply by serial connection ? Erase flash

I thought the Sonoff Dual boards don't support serial monitor. I compiled with option serial and debug level core but don't get any output. Am I supposed to enter something in the serial monitor? I also flashed with option ERASE FLASH All Flash Contents but nothing changes. I can flash the board without any problem but it doesn't respond afterwards. I thought maybe there's some issue in the firmware for Dual R2 boards.

The dual uses the UART to communicate with the secondary microcontroller, so you don't have serial debug. I have not tested a dual with the latest versions and I don't have one now to do so... I will have to try later this week. Maybe you can try flashing a simple sketch (a blink) to see if the board is ok...

I thought the R2 doesn't use a secondary microcontroller anymore? Should I send you one Sonoff Dual R2 so you can check it on your own?

xoseperez commented 6 years ago

Sorry, you are right. Then you should be able to get some info through serial if the flashing went ok.

Flashed the new 1.13.0 image. Flashing works fine but Sonoff Dual R2 still not responding nor sending info through serial. My Sonoff Dual R1 flashed just fine. There seems to be an issue with the R2 code.

Where do I get a blink code or (better) the original R2 code for the Sonoff Dual R2?

I just sent you 10 EUR through PayPal. Thanks for ESPurna so far. It helped me starting my home automation. Maybe you can order a Sonoff Dual R2 and check it on your own.

If you are not getting a single line of boot log I would say your device is broken. I would double check that you are using 115200 baud communication and that the device is working flashing a simple sketch that blinks GPIO13.

I was able to flash 1.13.5 today via uart. Don't know what caused the problems in the past. Closing.
