    Hello,

    I am trying to bring up a new board (ST10F269). With a scope I can see the reset in asserting low and P0L.4 asserted low. I can see the serial character (NULL) coming in on the RX line.

    The problem is that the TX line doesn't send out the 0xD5 character.

    The TX just sits at gnd.

    Any ideas on where to start?

    I found the problem.

    I have a Xilinx part that was driving the bus at reset. It drove the P0L.1 to low. The ST10F269 documentation is very thin on information about this mode.
