Arduino nano r4 troubles

Support
1

Hi,

I have bought two R4 Nano (threw one out) and trying to get connected to micropython. I followed the instructions downloaded Renesas flash programmer, downloaded the file, it connected and updated successfully, now it doesnt connect to anything. Is this another throw away?

Sorry first time trying, the Raspberry Pi Pico 2w was a dream to get going, I just wanted a little wifi board with usb c.

Any help will be greatly appreciated.

Hey there, @Justin224618,

Sorry to hear you’re having trouble with the R4 Nano, let’s hope it’s not a throw away one this time.

Just so we can get this sorted, would you be able to upload and tell us:

  • Photos of the R4 Nano so we can see if there is anything damaged on the board that could be affecting it?
  • Let us know what Operating System and IDE you’re currently using for the R4 Nano.

Thank you for reply.

I followed the in structions on here https://docs.arduino.cc/tutorials/nano-r4/bootloader-flashing/

As I want to use micropython, but now when I plug in, it doesnt produce any com ports, if I go back to flashing the bootloader and pre the connection it does bring up a com port. I assume its all me that caused it. The raspberry pi pico just worked easy, these look good but I am not a C developer.

Hey @Justin224618,

So a couple of things real quick.

So while it is theoretically possible to use the Arduino Nano R4 with Micropython, Arduino do not support it.. I think it will be unlikely that you can easily get it working with micropython.

Secondly, after booting and hitting the RESET button are you able to access the COM port if you leave the Boot-Ground connection attached and open the Arduino IDE?

Yes, if I ground it and reset the orange light goes off and when I open the IDE, I see com:6.

But after removing the Boot-Ground connection, disconnecting and reconnecting the board, it’s no longer connecting to the IDE’s serial ports. Is that correct?

7

Yes that is correct.
