Hello everyone, InSpace has manufactured our flight computer now, which is intended to run NuttX. It is STM32H743 based (VIT6 version). We would like to flash one of the existing STM32H743 builds from NuttX onto it to verify that it works before proceeding to create our own board support package. We are able to get access to its DFU loader via USB, and I can flash binaries to it. However, it appears all of the H743 binaries that exist are for flashing with an STLink or similar, not for DFU.
I have attempted flashing the chip with an STLink using the openocd commands suggested here, and the binaries can be flashed and verified properly. I am attempting to flash the chip with the configuration for the weact-stm32h743:nsh since it is the most similar to our board. I cannot seem to detect a shell on USART1 despite the binary flashing. I have also changed the definition of GPIO_LD1 (autoled) to be the pin PA4 where we have our status LED, and updated the HSE clock to 24MHz to match the frequency of the clock on our board. `ARCH_LEDS` is enabled and the USART1 pins have been modified to PB6 and PB7 to match our board setup. No luck yet getting a shell or seeing an LED blink. Wondering if anyone with experience porting to new STM32 boards has some debugging tips for us to try. Thank you for all your help so far!
