SK-TDA4VM: Interrupt development on SK-TDA4VM thru CCS12

DDM

Part Number: SK-TDA4VM

I used SK-TDA4VM as the development platform and XDS110 to achieve high and low level output control of GPIO0_97 pin, as well as online debugging on CCS12.

Question: I now need to develop GPIO0_71's falling edge external interrupt function and TIMER12's timer interrupt. Where can I find similar CCS engineering routines for reference? I am not very clear about the configuration of interrupt service functions and interrupt vectors, and having similar examples is more convenient for me to quickly grasp.

Thank you!

Hi,

Due to the Thanksgiving holiday, half of our team is currently out of office. Please expect a delay in response.

Apologies for the delay and thank you for your patience.

Hello,

Apologies for the late reply. Is this thread still open? Either way, assuming the thread is open and others will benefit from this thread, I will post a response.

As a disclaimer, we do not recommend developing R5F and RTOS code on the SK-TDA4VM, because most of the RTOS code example has been developed for the J721E EVM, which uses the same SoC but is a different board that has different pinouts. Please keep this information in mind if you choose to develop R5F code on the SK-TDA4VM, and also know that support from TI would be limited since we support RTOS and R5F development mainly on the EVM board instead of the SK board.

With the disclaimer in mind, we have a FAQ for GPIO configuration using PDK which includes how interrupts can also be configured: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1126741/faq-tda4vm-using-pdk-gpio-driver
