I have the same problem as this post [https://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/t/687409?tisearch=e2e-quicksearch&keymatch=GPIO%20k2l], which opened in May 2018 but I see no resolution posted.
I am running CCS 7.4, with the SDK RTOS K2L EVM 04.03.00.05.
I have the CN2 expansion port instrumented, and I see the GPIO all go to 1.8V on power - but I can not toggle/change state of any of the GPIO I instrument. I see the registers behave as expected (set and clear work on the GPIO register) but my oscope does not register any changes in the GPIO voltage - i.e. I can not toggle them.
I would like to know what it will take for me to toggle one of the GPIO (0-15).
