there are three uarts on dm6467, uart2 for cir and another two for other functions. I want uart1 to control camera,so uart1 interface is added. when uart0 and uart1 were connected to different monintors, i found that the output data was same(debug messeges). it's really strange.
in linux kernel configure,the uart number is set to 2(DeviceDrivers -->Character devices -->Serial drivers). After the system run,
# cat/proc/tty/driver/serial
serinfo:1.0driver revision:
0: uart:ST16654port:00000000 irq:40 tx:4206 rx:451 RTS|CTS|DTR|RI
1: uart:ST16650V2port:01C20400 irq:41 tx:0 rx:0 DSR
why the output of uart1 was same as uart0?
when i set uart number to 1,and after the system run,
# cat/proc/tty/driver/serial
serinfo:1.0driver revision:
0: uart:ST16654port:00000000 irq:40 tx:4206 rx:451 RTS|CTS|DTR|RI
also the output of uart1 was same as uart0.

Thank you for your help.
