Sipeed M0S Dock?

[WitoTV]

Hello,

First of all, thank you so much for making efforts to include Arduino environment for BL616.

Now to the real issue... I'm having some problems with getting Arduino code to run on my M0S Dock. Not sure if I somehow fried the board or it's something with the code or I am missing some important step I was supposed to do before trying to install Arduino on it. I could use some insight...

Code I'm trying to run:

int ledPin = 27; // or 28  
void setup() {
  Serial.begin(2000000);
  pinMode(ledPin, OUTPUT);
}
void loop() {
  Serial.println("Hello world!");
  digitalWrite(ledPin, HIGH);
  delay(1000);
  digitalWrite(ledPin, LOW);
  delay(1000);
}

Based on the log file I tried everything seems ok but I am not getting any reactions on the onboard led or in serial monitor.

Did you have attached UART to R / X / G pins? Also, this might be failure of board_init, due it expect pSRAM

[WitoTV]

Did you have attached UART to R / X / G pins?

No, I did not... Was I supposed to? I was expecting it to work via the USB C port on the board (well it worked for detection after holding boot button on the board and plugging it in). I sadly don't have a converter at my place currently to check with it... I would be able to get it back tomorrow earlies... So I could update on that after I get it in my hands...

Also, this might be failure of board_init, due it expect pSRAM

What can I do if that would end up being the case? I remember reading something about pSRAM issues with some Wi-Fi exampels when Wi-Fi/Bluetooth APIs were publicised for the SDK but I don't remember what was the exact topic...

[WitoTV]

@gamelaster update. I got my hands on the USB/UART converter and connected it to dedicated R/T/G pins on the M0S Dock. No effect, Arduino does not even want to connect to serial when used this way... Should I try to connect to it with something else?

(I have as well a nondock version of M0S, I could try to wire it up with some enamelled wire (first I need to find where to buy some here) to some pins and breadboard and see if I could get that running...)

[Opisek]

@WitoTV Have you found any solution?

[WitoTV]

@Opisek nope. I have gave up. Nothing I tried worked. And I did not have time and mental strenght to get new one to see if its faulty unit. Are you by any chance having the same issues?

[Opisek]

Yes I am. For now I think I'm giving up on this microcontroller. The documentation is non-existent and I'm not experienced enough in FreeRTOS to try to reverse-engineer or guess how to program this without the Arduino framework. Waste of money.

I've just bought an ESP32-C6, which seems to be exactly what BL616 promised to be, but with the level of documentation and support that's to be expected from Espressif. And wouldn't you know, Zigbee is actually enabled in their SDK as opposed to BL616 :)

Perhaps I'll return to them after I've gathered more experience or Sipeed actually puts any effort whatsoever into their SDKs and documentations. Honestly sad to see them give up a potentially big market like that. The chips seemed great on paper.

[mtuxpe]

I believe that the Sipeed M0S Dock board has some incompatibility related to PSRAM. Using BL616 with the AI Thinker kit (https://docs.ai-thinker.com/en/ai_m62) the GPIO works (not on all pins). I'm still going to test the UART and wi-fi on the ai-thinker. Of course Espressif ESP32-C6 is an option with more documentation and support.
