[En-Nut-Discussion] UART example for AT91SAM9260-EK

Hi Lasse here "home email"

Its the example code which its part of the Nut/OS code. Made by you


NutRegisterDevice(&DEV_UART, 0, 0);
uart = fopen(DEV_UART_NAME, "r+");
_ioctl(_fileno(uart), UART_SETSPEED, &baud);

The events and the tcps example works fine btw. So it is not some
compiler setup stuff.

After go 0x200... Noting on the Hyperterminal. I can download a Atmel
example (Non Nut/OS application) and get a input/Output over the Uart0
DB9 connector, so my hardware is working and my cable is connected

Best regards

OK, Lasse. How does your UART initialization look like? I mean the lines

similar to

   NutRegisterDevice(???, 0, 0);
   freopen(???, "w", stdout);
   _ioctl(_fileno(stdout), UART_SETSPEED, &baud);

Still missing the answer to
