GPIO_ACTIVE_HIGH in M4 MCU

vinothkumars — Fri, 18 Jun 2021 12:24:23 GMT

Hi All,

I have to configure gpio as high. I am doing like that but, It is not working.

 err = sc_pad_set_all(ipc, SC_P_GPT0_CAPTURE, 3U, SC_PAD_CONFIG_NORMAL, SC_PAD_ISO_OFF, 0x60 , SC_PAD_WAKEUP_OFF);
if (SC_ERR_NONE != err)
{
PRINTF(" Make SC_P_GPT0_CAPTURE gpio failed\r\n");
assert(false);
}

Hi Vinothkumar

if codes are running from M4 side one can look at SDK_MEK-MIMX8QM examples

https://mcuxpresso.nxp.com/en/welcome

For configuring gpio as high one can look at below link, pay attention to MUX_MODE and GPIO

Thank you Igor for the quick reply.

Yes, I am using same pin mux functionality only.

Will you please provide example for GPIO_ACTIVE_HIGH using sc_pad_set_all .
