I have to use Emcraft's STM32H750XB System on Module for a freeRTOS based application. I haven't soldered male berg pins on any headers. I am referring Emcraft's schematic to check pinouts. I thought I would first test out all peripherals without RTOS using cubemx because there are very limited pins available from the MCU. Printing with USART2 on serial monitor works perfectly fine. When I try to toggle to any GPIO which is connected to an external LED, it doesn't blink but I could see the mode being set to output mode, even the output data register of that pin seems to toggle as seen in SFR tab but nothing out. When using I2C4 for no slave dummy transmission I am unable to see any data in SDA line, but I can see something in SCL like 3 square waves non periodic. Same goes for SPI4 dummy no slave transmission, I can only see MOSI data line but nothing in SCLK line. I know there are full fledged freeRTOS demo applications for this SOM on Emcraft's, but I want to figure out what's the issue with baremetal.
