Hey list I have a custom MPC875 board running 2.6.37. SMC1 is the console, SCC4 is a general purpose UART (DTS is set up accordingly). No hardware or software flow control for either.
The issue is simple: the non-console UART transmits garbled characters at the end of the transmission. For example, set up SMC1 to console (works perfect) and SCC4 as non-console, run stty -F /dev/ttyCPM1 19200 raw and then echo -n 1234567890 > /dev/ttyCPM1 - transmission may be something like "1234567ΓΈ". Set the SCC4 as console (same baud rates) and the problem is reversed (SCC4 works perfect, SMC1 transmit garbled). Rx direction seems fine, after some rudementary testing. I dived into the code and see that the console UART has a completely different initialization sequence than the non-console UART. Short of diving into this ancient CPM architecture - does anyone have an idea? Thanks Eran
