I have bought the Maixduino board from Sipeed, and wish to program it using Arduino IDE.
In File-Preferences Additional Board Manager URLs I have set the path:
This is correct; it finds the file.
However, when I use Board Manager to install the board, I get error message:
http://dl.sipeed.com/MAIX/Maixduino/package_Maixduino_k210_index.json file signature verification failed. File ignored.
I have tried deleting the Arduino15 folder and then restarting Arduino IDE, but the error persists.
I have searched the forum and found several posts on this problem, but there is not much advice on possible solution. One post suggests I launch a CDN refresh, but I have no idea how to do this.
"flash_999" has a post on Mar 29 2020 which says:
"Without making any further changes, the problem went away. This could indicate the issue might have been a transient network caching problem."
So, should I just wait for the problem to go away; might be a long wait ?
I'll be grateful for any advice; many thanks. Ken.
My PC is using Windows 10 Home, version 1903
