B4R Question Esp32 board list

[yaqoob]

Hello,
I am using the M5Core3. It has an ESP32S3 controller. I added the M5Core3 board to the Arduino board list. The original ESP32 board was already on the Arduino board list before. When I search for M5core3 boards in the Arduino application, both M5Core3 and ESP32 are listed in the Arduino board list (Image 1). I can choose which to select. In the b4R application, it shows only one (Image 2). I found out that it only displays the ESP32 version, and even when selected, it does not provide the correct results. To solve the problem, I had to uninstall the ESP32 board and keep only the M5Core3 board to make it work; however, this resulted in my being unable to find the other ESP32 boards in the list. Does anyone have suggestions on how to solve the problem and make the B4R application display both a board, similar to an Arduino Application?

If to select just ESP32S3 dev board (with all esp32 installed) - is it not enough for M5Core3 development ?

No, it's not. The M5Stock libraries are needed for the M5core3 board.

It look like you do not understand well the electronic structure.
Any custom board may have some presets of all settings of the used MCU.

"Dev board" means the MCU with all possible settings of the MCU, all is possible to setup.
I'm sure that if to know the board documentation - you can use any board with "xxx dev board" variant, if to choose the documented settings of the MCU in "Board manager".
