Error when adding Seeeduino boards to IDE

Products & Technology Arduino & Seeeduino
#1

Hello, Sorry I’m quite new to this.

I’m running Arduino IDE 1.8.12

I am following the following instructions:
https://wiki.seeedstudio.com/Seeed_Arduino_Boards/

Most of it seems to work okay. I can get the AVR package and select my V4 Seeeduino board in the board list.

But I keep getting these errors all the time now:

Index error: could not find referenced tool name=riscv64-unknown-elf-gcc version=8.2.0 packager=Seeeduino
Index error: could not find referenced tool name=kflash version=1.3.0 packager=Seeeduino
Index error: could not find referenced tool name=kendryte-standalone-sdk version=0.5.6 packager=Seeeduino

Should I do something about this?

You can delete the incomplete Arduino packages in the wrong place.If you still need it, you can install it again.

#4

Arduino 1.8.12 is broken (its the compiler not finding precompiled libraries).
You need to revert to version 1.8.10, and make sure to remove any Board upgrades that were done. ( Might need to clean out $user/$username>/appdata/arduino15 ). When you do this, you may need to set up preferences again. This is not for feint-hearted, you need to be bold and confident you can fix it if it breaks, which it will.

#5

I have reverted to 1.8.10, cleaned out my Arduino15 directory, and even cleaned out my Arduino project directory so I could do a clean install of all my libraries. I am still getting the following block of errors. I suspect it isn’t about 1.8.12 of the IDE being broken, but I don’t have a solution.
