how to do pin muxing and module clock config for UART2-5 on beaglebone

Yanli Hu

Hello,

I'm using StarterWare and Beaglebone and I have been using UART0 and UART1 in my application. Now I need to utilize more UARTs, but it is not clear to me how to do the pin muxing and module clock configuration for UART 2-5. Can anyone offer any help? Any info is appreciated!

I assumed that CONTROL_CONF_UART_RXD(n) in platform/uart.c could be used for UART2-5, which was proved to be wrong. Putting together the information found on page 1220 of spruh73b.pdf and on page 60 of http://beagleboard.org/static/BONESRM_latest.pdf, now UART2 is working. Thanks!
