Hello,
if try to reproduce the STM32H743-EVAL board, is it possible to program its NOR FLASH (MT25TL01GHBB8ESF) if i use the existing external loader? I think the answer is yes. However, i can put in my board just the STM32H743II MCU instead of the STM32H743XI present in the original board.
Before i try to do this, will the programmer returns error if i try to program my custom board?
It doesn't query if it is the 1Gbit part, or pair of 512Kbit ones. It doesn't verify it can talk to it properly, although the memory read/verify is apt to fail if expectations aren't met.
It makes assumptions about the size of the memory device, and the command set.
It also doesn't double check if it is a H743, H745, H750, etc, so the loaders are reasonably interchangeable provided that the QSPI connectivity is consistent. Some of the DISCO and EVAL examples use different combinations, so there is some flexibility there in terms of finding a loader that matches. The loaders can also be patched.
