Hi
Recently I am working with a project. I design a 8x serial communication port board to use with OMAPL137 DSP board.
I used two ST16C554, each with 4 serial port, so total 8 serial port there and the 8x interrupts of ST16C554 are combine into to two interrrupts to DSP by CPLD
The two interrupt to DSP are connected to EMA_D[8], EMA_D[9] respectively.
The 8 bytes data bus from ST16C554 are connected to EMA_D[0] -- EMA_D[7] respectively.
These serial port base address are mapped to EMIFA base address.
Now I can send data and receive date through the serial port by continuely monitor the serial port register status.
I want to use interrupt to handle the serial port event and send and receive data.
I have setup the EMA_D[8], EMA_D[9] by PINMUX register as GPIO0[8] and GPIO[9].
and configed the event 65 (which is for GPIO interrupt ? ) through TCF as default interrupt handler
I use HWI 8 for event 65 .
Now the problem is the interrup could not be get called.
Is it right that I do ? How should I do the next ?
I would be really grateful for your help
Please forgive my bad english.
Thanks
