TMS320C6678: GPIO INTERRUPT: GPIO interrupt not working properly.

Part Number: TMS320C6678

Hi Ti Team,

We configured the event on the GPIOs ( using this TMS320C6678 System Event Inputs — C66x CorePac Primary Interrupts), We tried a lot for the interrupt generation on the GPIO if this configuration is correct, So how to check the interrupt occurrence (enable or disable) on the GPIO using CCS or other resources?

Please also review the images mentioned below.

PFA,

>> This is configuration.

>>In the below image We want to interrupt on C0..1..2..3 (in 4x4 keypad)

In this image we want to interrupt in this gpio pin

Please guide us for the same.

Warmest regards,

Krishn Singh Chauhan,

I have created a new FAQ to check the system events and the mapping of interrupts to the core-pac

Please have a look.

Utilize this code for testing any system events/Event flag registers/ INTC-interrupt mapping-out of 12 interrupts etc...

Hi,

Thanks for the update, We already did that test.

Please close this thread.

Krishn Singh Chauhan,

When you say, you already did the test, did it work for you?

Hi,

Yes! Please Look at 1st image we mentioned above for the INTC configuration.

We got access to the eventIDs using INTC Configuration at the GPIO. But We are not sure if it's working or not because We want to cross-check if CCS have such type of tools or configuration to check the interrupt generated or not, like debug H\W.

Please close this thread. We have half a solution to it If We get a complete resolution then we inform you ASAP.

Warmest regards,

No such tools available in CCS.

Hi,

As per our discussion,

We resolved that issue completely, Now We have access to the interrupt on the GPIOs using the Memory Region.

Note: No such tools are available in CCS for checking whether the Interrupt was generated or not, That's why we cross-checked it using H\W.

Warmest regards,
