AM2754-Q1: How to use GPIO(K18) on AM275?

Tool/software:

Hi Experts.

Our customer would like to use GPIO with using following API. But it seems doesn't work. Could you instruct them how to use GPIO.

- debugGpio_toggle(mcasp_debug_pin)
- debugGpio_high(mcasp_debug_pin)
- debugGpio_low(mcasp_debug_pin)

What is the procedure for enabling GPIO debugging in AWE-SDK?

How to configure of Ball K18. Customer haven't configure it to Sysconfig.

Best regards,

Ito

Hi Ito-san, Ritapravo-san,

As a result of code analysis, it seems that the address translation in the AddrTranslateP_getLocalAddr() function is not done correctly.
It seems that the address translation process is based on the data set in the gAddrTranslateConfig structure, but the design concept for the gAddrTranslateConfig structure is unknown.

Hi Ito-san,

I just verified the GPIO debugging using mcasp_debug_pin (K18) and it is working for me in AM275.

To enable this do the following steps.

Call the debugGpio_setup() function from TuningServerCreate() function [{$audio_sdk_path}\audio_app\common\src\TuningDriver.c]
```
int32_t TuningServerCreate ()
{
   debugGpio_setup();
   awe_ipc_setup(&ipcObj);
   return SystemP_SUCCESS;
}
```
Add the line debugGpio_toggle(mcasp_debug_pin); where you want to toggle the gpio.
Connect the Audio Expansion Connector #2 to the evm.
Connect the logic analyzer input to pin number 30 (MCASP2_AXR3) of the Audio Expansion Connector #2 and you should be able to get the gpio output.

Regards,
Ritapravo
