We were using STM32H730VB to drive a LED display in our project. Pins 51 - 64 drive the LED display, Pin 30 controls the display power, and pins 24 - 25 act as the USART. We use CubeProgrammer to download the firmware.This worked well and with no is...

Our main PCB has multiple MCUs. We have an additional PCB that we designed specifically to program the MCUs. We first turn on the main PCB, let it run for an extremely short amount of time, and then put the STM32 into bootloader using the programmer ...

I was under the impression that as i am using USART 2, it wouldnt effect PB15. However, that does not seem to be the case. I guess the best option for us would be to use another pin instead of PB15.Thanks for your help.

I went through it once more, and noticed that in the known limitations section, it mentions that if PB15 is grounded STM wont enter bootloader mode. The display does seem to ground the PB15 pin, so, in the current setup, a 750H will not work.Thanks f...

Substituted STM32H730VB for STM32H750VB on PCB due to chip shortage. 750 does not enter bootloader due to pin PB15. Is there a fix for it?
