Hi,

 

UART2 is working for us.

A nice summary of the changes needed is described here:

(this is for UART1; it should also work for UART2)

Subject: Enabling UART2 on DaVinci

 


Hello, 

I'm trying to enable UART2 on the DaVinci. I have UART0 setup to be the
console, and would like to use the UART2 to communicate with an external
device. 

I am able to get the kernel to allocate MMIO to the serial port, but I
do not see data going through. 

# cat /proc/tty/driver/serial 
serinfo:1.0 driver revision: 
0: uart:16550A mmio:0x01C20000 irq:40 tx:3036 rx:524 RTS|CTS|DTR|DSR 
1: uart:16550A mmio:0x01C20400 irq:41 tx:0 rx:0 CTS|DSR 
2: uart:16550A mmio:0x01C20800 irq:42 tx:0 rx:0 CTS|DSR 
3: uart:unknown port:00000000 irq:0 

I was able to get to the point this thread got:
http://osdir.com/ml/linux.davinci/2006-12/msg00070.html 

But I still can't send or receive data out of UART 2 or 1. 

Thank you for your help. 

Du
