Hi all!
Now we want to use the uart1 on dm368.
but we can only send data and can't receive response.
the serial's info as follow:
# cat /proc/tty/driver/serial
serinfo:1.0 driver revision:
0: uart:16550A mmio:0x01C20000 irq:40 membase 0xFBC20000 tx:413 rx:20 RTS|CTS|DTR|DSR
1: uart:16550A mmio:0x01D06000 irq:41 membase 0xFBD06000 tx:0 rx:0 CTS|DSR
# cat /proc/interrupts

54: 0 AINTC mac_tx
55: 0 AINTC mac_misc
61: 0 AINTC EDMA TC2 Error

we can't find uart1's irq in the table
Is it the reason why uart1 can't receive data?
what should we do for this?
Best regards!
