[AM335x] Board Porting - Enable UARTs beside UART0

Other Parts Discussed in Thread: AM3358

HI.

I have enabled all UARTs on AM3358. I finished all porting processes yet. Now, UART from 1 to 5 , all the ports can send data, but can receive nothing. How should I solve this problem. I am crazy !!

Is it the kernel from the AM335x TI SDK?

If yes check your pinmux settings in /sys/kernel/debug/omap_mux/.

Example:

cat /sys/kernel/debug/omap_mux/uart1_rxd

Best regards,
Miroslav

Thank you very much!

I solved this problem!

I used wrong macros which defined for 44xx for my uarts pin-mux definitions.
