Re: PSC in UART mode on TQM5200S

["Leopold Stotch" <l.butterz@gmail.com>]

Thank you for the answer, Wolfgang !
Yes, we made a custom board which implements UART's
instead of USB, keyboard, mouse and others...
I checked the baudrate and i think it's ok.
Can you tell me, please, is there any HOWTO about MPC5200's
PSC's reconfiguration or something for newbies ?
