Solve the problem already. Somehow in /io/serial/currentsrc/common/serial.c,
in serial_read function, the checking for blocking was wrong.

Subject: [ECOS] Serial application


I wrote a test program to test the serial port on my platform (AT91EB40).
This program simply transfer data received from one port to the other. I
have two threads, each will monitor one serial port. Below is the codes.

Thread 1:
static void simple_prog1(CYG_ADDRESS data)
{
    cyg_uint32 buf_len;
    cyg_uint8 in_buffer[10];

    while (1) {
        buf_len = 1;
        cyg_io_read(serial1, in_buffer, &buf_len);
        buf_len = 1;
        cyg_io_write(serial0, in_buffer, &buf_len);
    }
}

Thread 2:
static void simple_prog2(CYG_ADDRESS data)
{
    cyg_uint32 buf_len;
    cyg_uint8 in_buffer[10];

    while (1) {
        buf_len = 1;
        cyg_io_read(serial0, in_buffer, &buf_len);
        buf_len = 1;
        cyg_io_write(serial1, in_buffer, &buf_len);
    }
}

When I start the program, it just run for a few seconds then stops. Can
anyone tell me what's wrong?

Thanks
Stanley
