hi, everybody
I am trying to use UART1 port of DM365, the driver doesnot work well and the following is the proc information.
root@dm365-evm:~# cat /proc/tty/driver/serial
serinfo:1.0 driver revision:
0: uart:16550A mmio:0x01C20000 irq:40 tx:1392 rx:29 RTS|CTS|DTR|DSR
1: uart:unknown mmio:0x01C20400 irq:41
I can open the /dev/ttyS1, but when it is configured or some action else, it print error : /dev/ttyS1: Input/output error
The version of DVSDK is 4.02.
Maybe the UART1 is not enabled correctly but I did not find where to fix it .
Thanks.
