Seeeduino Xiao boards manager not showing boards

[anandjhaveri]

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
at [Source: (FileInputStream); line: 3805, column: 1304]

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.

NO ONE from seeed works here! (HINT)

As @missdrew said. You better contact Seed studio.

In the meantime...
That file opens fine in a browser.
Close the IDE, then put the file in your arduino15 (or portable) folder, alongside the other json files you may have already. Then check if the IDE picks it up.
If that works, you can try to download the rest from the board manager.
But if the cause for the truncated file is in your side (PC/network/etc.), this may fail too...

I posted on the Seeed forum and the issue has been resolved. It was a problem from their R&D team which has now been fixed.

Thanks for your help @missdrew and @rainyshadow. Much appreciated.
