I am having a strange (to me) issues trying to program an STM32H743VI.
I have had the PCB manufactured and assembled by a different supplier and all of a sudden I cannot program the STM32H743....
I do not have the NRST pin back to the STLink-V2, only the SWDIO pins, GND and 3V3.
It's as if it is not booting correctly, but not quite sure where to look to see what is happening, or what could have changed! Certainly the design is identical, only the supplier is different.
I have verified the 100nF cap on NRST, and the 10K resistor on BOOT0. Both OK.
