[ECOS] Serial interrupts on the AEB

["Gareth ." <the_african at hotmail dot com>]

Hi,

I'm having some trouble getting the serial port to set off an interrupt on 
the ARM evaluator board. I have successfuly got the interrupt button on the 
board to set off an interrupt and have appled the same stratergy to the 
serial port. To get the button to interrupt I used :

cyg_interrupt_creat(CYGNUM_HAL_INTERRUPT_EXT0, 0, 0, &button_isr, 
&button_dsr, &button_isr_handle, &intr);
cyg_interrupt_attatch(button_isr_handle);
cyg_interrupt_enable();

Now every time the button is pressed the function button_isr is called.
To get the serial interrupt working I did :

cyg_interrupt_creat(CYGNUM_HAL_INTERRUPT_UART0, 0, 0, &serial_isr, 
&serial_dsr, &serial_isr_handle, &intr);
cyg_interrupt_attatch(serial_isr_handle);

But now nothing happens when data is sent to the serial port. I am thinking 
global interrupts must be enabled or else the interrupt button would not 
work. Is it possible interrupts on the uart are not enabled? I do not think 
this is the case because I can get data from the serial line using scanf so 
the port must be configured properly.

Can anyone offer any advice?

Sincerely,
Gareth
