Hi Experts,
Good day! Please help to check the full details of our cusotmer's inquiry below.
Currently we are working on GPIO module for Am3358 controller. We are able to control default GPIO pins but couldn't control multiplexed functionality pins. How to set mode(7) to work as gpio pin.
We are using code composer studio 10.4 version and Ti latest SDK version.
Please guild us how to control GPIO functionality for multiplexed pins.
I am using generated examples code(GPIO_BlinkLED example) in
ti\pdk_am335x_1_0_17\packages\MyExampleProjects\GPIO_LedBlink_bbbAM335x_armTestProject
Attached files for your reference.
