@folknology
I'm trying to support blackice mx on some project.
stm32 uart baud rate facing the FPGA is hardcoded to 115200. Combined with the lack of hardware flow control, my design's FIFO does overrun, thus I have to depend on an external usb-serial converter, as the alternative would be too much work for one board's special case.
It would be best if uart speed was set to computer's requested speed.
