Other Parts Discussed in Thread: SYSCONFIG
Hi,I want to control main domain gpio in r5f mcu (mcu1_0),I follow the drv document and write the demo to toggle GPIO0_64,but it seem there is no effect，did I miss something？is there any demo of controlling main domain gpios in mcu island? thanks!
here is my code.
In "J721E_pinmux_data.c",I add GPIO0_64 pinmux by sysconfig tools
/* MyGPIO0 -> GPIO0_64 -> AD28 */
{
PIN_PRG0_PRU1_GPO1, PIN_MODE(7) | \
((PIN_PULL_DISABLE | PIN_INPUT_ENABLE) & (~PIN_PULL_DIRECTION))
},
