If all that you want different from the default configuration is ttyO4 working, then Winston's advice is good. If there are other/additional changes, then you will need to make additional edits or changes to the ".dts" or ".dti" files. --- Graham == On Thu, Mar 12, 2015 at 12:21 PM, wrote: >

Hi Robert, Sorry, this created /dev/ttyS4 indeed but it does not seem to work. I also checked for echo by shorting UART4 RXD P9-11 to TXD P9-13. and UART1 RXD P9-26 to TXD P9-24. TIA, Regards, Enoch. Robert Nelson writes: > On Wed, Mar 11, 2015 at 5:53 PM, Enoc
