CCS/AM3352: GPIO interrupt triggered EDMA

Part Number: AM3352

Tool/software: Code Composer Studio

External devices will generate a GPIO interrupt to am3352.

How can I configure GPIO so that it can generate an event,

and how can I configure it in EDMA so that it can start EDMA transmission at this time.

My PDK version is processor_sdk_rtos_am335x_5_02_00_10

and the EDMA driver version is edma3_lld_2_12_05_30C.

Thanks!

Hi User5954100,

You need to modify the existing GPIO RTOS example, which is currently supporting interrupt only. Please refer to below pointers for more info:

AM335x TRM, section 11.3.18.4.5.1 Servicing Input/Output FIFOs with a Single Event

Regards,
Pavel
