STM32H747XI support in boards.txt?

[radiohound]

Hello, I was wondering if there was a reason that XI chips like the H747XI are not included or generated in the boards.txt file? It is already in the variants list. I tried adding the following to my boards.txt, located in my Arduino15\packages\STMicroelectronics\hardware\stm32\2.1.0 folder. but it does not get picked up in my "board part number" dropdown for genericH7 boards.

<# Generic H747XITx
GenH7.menu.pnum.GENERIC_H747XITX=Generic H747XITx
GenH7.menu.pnum.GENERIC_H747XITX.upload.maximum_size=2097152

Hi @radiohound
All MCU have a default variant generated, anyway it requires to add manually the linker script and declare it in the boards.txt.

If you don't see it there is probably an issue in your declaration or maybe you didn't restart the Arduino IDE.
