B4R Question Compiler abort due to a board problem?

[thali]

After installation of new board types (e.g. M5Stamp) on the Arduino IDE 1.8.15, B4R 3.9 stops with :
.......
DEBUG StatusLogger Shutdown hook enabled. Registering a new one.
DEBUG StatusLogger LoggerContext[name=1e6f5c3, org.apache.logging.log4j.core.LoggerContext@49a9c1] started OK.
Preparing boards...
Error: EraseFlash: Invalid option for board "m5stack-core-esp32"
DEBUG StatusLogger Stopping LoggerContext[name=1e6f5c3, org.apache.logging.log4j.core.LoggerContext@49a9c1]
DEBUG StatusLogger Stopping LoggerContext[name=1e6f5c3, org.apache.logging.log4j.core.LoggerContext@49a9c1]...
.......
The B4R project (with M5Stack-Core board) can be compiled on an other machine and the src.ino project, translated by B4R on this machine
can be compiled with the Arduino-IDE.
Third, a B4R project with an M5Stamp-C3-board is compiled well on this machine.

What's happend with the board management in B4R and how can I make it running again?

Tip: Getting rid of the excessive compiler logs

Are you sure that all the board settings in the board configuration dialog are identical?

Your are right!
The board that fails has one more parameter: 'EraseFlash'. Why this?
I can set the this to 'none' or 'all' but compilation always fails...

At the Arduino-IDE the parameter ''Erase All Flash Before Sketch Upload" is disabled and compilation works!
Where is the dog?

Probably a different version of the installed board SDK. It comes from the Arduino IDE downloaded metadata.

Solved! The board 'M5Stack-Core-ESP32' was defined twice in the packages:

https://dl.espressif.com/dl/package_esp32_index.json

https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/arduino/package_m5stack_index.json

So, I removed the upper line in the Arduino-IDE settings, restart IDE, and compilation works again in B4R. - Thanks: Great tool!
