i have 168MHz stm32f407 discovery codebase https://github.com/rusefi/rusefi/tree/master/firmware running cbibios 20. As a step towards K-line I am trying their weird 10400 baud and it does not work?!
9600 and 14400 works fine. I've already used a logic analyzer to confirm that my CP210x TTL dongle produces at least something at 10400
Do we expect 10400 to be supported by stm32? Do we expect 10400 to be supported by cbibios? What else could I be missing?
UART 9600 and 14400 works but not 10400?

Hi,
ChibiOS does nothing about the baud rate except setting the UART prescaler, is that rate obtainable starting from the input frequency? you may want to check that the register value is what you expect.
