STM32F429I-DISC1 - UARTS dont work ??

Hi I m fairely new to development on STM boards. The UARTS on stm32f429i-disc1 pins doesnt seem to work. I have tried all combinations of uart pins available ,to connect to pc using a ftdi usb adapter, but the damn thing will not work. I have also tried changing baudrates, ports and even completely different ftdi usb adapters. Has anyone got the uart pins to communicate with ftdi usb ,on this board ?


Hi. Which compiler are you using ? Is it mbed ? What have you tested exactly ? Please post your details of the pins you are using, the code which is not working using the <<code>> and <</code>> tags for proper formatting. Are you not seeing the output data from this STM board to the host PC using Teraterm or similar program ? Start with confirming the proper mbed target board is installed in your account and import the following example program https://developer.mbed.org/handbook/Serial. Be sure to use the proper UART port pins to capture the transmit out data by the external USB to serial dongle. The baud rates must match the mbed source code.
