3.3.4 Flash memory architecture and usage
• For STM32H750xB devices: a 128-Kbyte user Flash memory block containing one user sector of 128 Kbytes (4 K Flash words)
3.3.10 FLASH erase operations Erase operation overview The embedded Flash memory can perform erase operations on 128-Kbyte user sectors, on one user Flash memory bank or on two user Flash memory banks (i.e. mass erase). The system Flash memory (bank 2 only) can also be erased, but by STMicroelectronics secure firmware only. Note: System Flash memory bank 1 cannot be erased by the application software.
Looks like ST just pitched a shutout. Does anyone have any experience with this either way?

Don't have a H750, perhaps look an see if there is additional FLASH and they only tested one 128KB sector.
Wouldn't preclude you from journalling a small amount of configuration data
I2C EEPROM devices are small and readily available.
