Peripherals not working in STM32 BL475E
When I use my STM32 BL475E IoT Node for operations not involving peripherals like blinking the onboard LED,serial printing to monitor,Running an AI model they are working properly.But when I tried to blink an external LED it is not working.same applies for all ports in the peripheral.They neither accept input nor displaying the output.What may be the problem...
