Does "Erase full chip flash memory" wipes any factory values that I should save?

Hi all, I’ve seen in other manufacturers MCUs( sometimes) calibration values that may get lost if I wipe out the whole chip. It was long long ago.I’m new to this STM32U5 series. I’m working with the STM32U5G9J-DK2 kit. I’m porting the LCD stuff to my

In my application on an STM32H7S3 I’ll have to often read option byte keys, and I want to limit the possibility of accidentally writing to option byte keys.According to the reference manual, that’s where the PG_OPT bit of FLASH_OPTCR comes in:PG_OPT:

NUCLEO-H5E5ZJ — Redrawing the Schematics as a GPIO View

I have redrawn the NUCLEO-H5E5ZJ schematic as a personal exercise in understanding the architecture of the board and the STM32H5E5. I have consolidated the original multi-sheet design into a main STM32H5E5 schematic and a separate STLINK schematic,

ChromART and repeated calls

I’ve got a working graphics system. It does high level operations on a 32 bit virtual image of the display’s resolution. The image is then translated to a 16 bit buffer image (RGB565 for an ILI9341 display). That image is then transferred over SP
