Seeeduino v4.2 doesn't show up in ports

I’m trying to get my seeeduino v4.2 to show up in a port on my Mac. I’ve downloaded the boards package and still no luck.

Anything else I can try?

Hi there,



please try below things.


  1. change to another usb cable
  2. please change to another pc
  3. if both of them does not work, please download below package and refer to instructions. thanks.

I’m encountering same thing.



I can’t connect to the board, so not sure how I could burn a new boot loader…



I’m thinking that there is USB issue with Mojave. I’ve updated USB drivers (as per your documents) to the 2.4.2 version (latest on FDDI site)



No port shows up now so can’t connect to Seeeduino…



Other ideas? (I’ve tried this on 2 Macs, same symptoms)

OK, after random changing of USB cords, and re-loading drivers multiple times, I have it showing up on the port…



However, won’t download anything. Keeps generating the following:

Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.



That’s just trying to load “Blink”.



Not sure what “Programmer” should be set to… On your web pages I’ve seen mentioned “Parallel Programmer”.

I’ve tried 5 or 6 different versions of the Arduino IDE… 1.6.x, 1.8.X. Got to the above with 1.8.X versions…



Tried resetting board multiple times… board LED is flashing (which according to docs means bootloader is loaded…)



Thoughts??

I have the same problem to the letter. I just wasted hours getting drivers to work, now the damn thing doesn’t show up with a COM port. Arduino compatible my ass!

I’ve found a handful of forum posts stating exactly the same issue I have and none of them get resolved. Has anyone got any info on this?

What version of the system are you using?

I assume you mean what version Arduino IDE am I using? 1.8.19

We have encountered similar problems before and the two main reasons for this problem are.

  1. The USB cable used is unreliable and the computer does not recognise the Arduino, it is recommended to replace the original cable.
  2. It is possible that some of the driver components were intercepted by anti-virus software when following the Arduino and were not installed properly, we suggest uninstalling and reinstalling the Arduino. Or use the latest Arduino 2.0 to try.
