Hi I tested in my mini2440 uart interfaces and I have a problem - uart 1 and 2 send and receive data, but the uart 0 does not receive - send data is ok. I tried from the linixa and windows via the included RS232 cable, does anyone know what causes this?
Uart0 receive data
it is because it has been designated as the "debug" console.. If you connect to this and boot up the system you should see system debug.
