UART5 Configuration - sb-fx6

Question asked by Andrew Palmer on Jul 1, 2016
Latest reply on Jul 4, 2016 by Andrew Palmer


I have built a linux yocto image to target a sb-fx6 evaluation kit which works and boots fine. However when linux has booted I only get access to the command console serial port. What I wish to do is configure UART 5 on this board so that linux will recognize it as a serial port.


I realize I need to configure the pins appropriately (because they a multiplexed) but being in fairly unfamiliar territory  I have failed to find a suitable example to follow.


From the reference manual I have identified the pad names (UART5_RX_DATA and UART5_TX_DATA) and the registers (IOMUXC_UART5_UART_RS_DATA_SELECT_INPUT ...) but I don't how to apply this to the linux kernel and do a build.


If any one can help point me in the right direction that would be greatly appreciated.
