Arduino IDE Boards manager not showing Seed boards

Products & Technology Arduino & Seeeduino
#1

I have just bought the Seeeduino Xiao board and was trying to get it to work with the Arduino IDE.

I have put the following URL into the additional boards manager list of URLs

https://files.seeedstudio.com/arduino/package_seeeduino_boards_index.json

However, when I go to the Tools->Boards->Boards Manager, I am not seeing any Seeed boards and I get the following error:

Skipping contributed index file C:\Users\anand\AppData\Local\Arduino15\package_seeeduino_boards_index.json, parsing error occured:
com.fasterxml.jackson.databind.JsonMappingException: Unexpected end-of-input within/between Object entries

I checked the .json file and it is truncated abnormally. So, there seems to be some issue when downloading this file.

I would be very grateful if anyone can help to resolve this issue.

Anand.

Sounds like a network problem.

I have this problem too. I can not use any of my XIAO devices. I am using the latest Arduino 2.0. What do I do?

Can you provide more information? For example error logs etc.

You must have fixed something because it works now. I did not do anything differently to look for the board than I did before, but it worked this time…
