Question
Flashing code with stlink does not run code
I used the STM32CubeIDE to make a simple LED flashing program for an STM32H753. When I run the code with the CubeIDE, it uploads and flashes the LED as intended.
I would like to be able to run this code without the CubeIDE. I am on Mac and have stlink tools installed. I tried running:
st-flash write STM32H753XIHX_FLASH.ld 0x8000000which outputted:
st-flash 1.7.0
2023-03-08T10:36:48 INFO usb.c: Unable to match requested speed 1800 kHz, using 1000 kHz

2023-03-08T10:37:34 INFO common.c: Flash written and verified! jolly good!Both seemed to have valid outputs, but neither make the LED flash. What could I be doing wrong?
Thanks
