Changing TRDC configuration for GPIO2

deepshika_borundiya — Fri, 17 Oct 2025 13:55:08 GMT

I am trying to control GPIO_IO16 from M core on GPIO2. To do so, I'll have to chane configurations of SM: mx95evk.cfg, scmi.h and tdrc.h. However, I am unable to identify PAC of GPIO2 in TRDC headerfile.

Hello @deepshika_borundiya

Have you tried updating the pin_mux.c file?

Those are the possible mux for GPIO_IO16:

In your iomux file:

IOMUXC_SetPinMux(IOMUXC_PAD_GPIO_IO16__GPIO2_IO_BIT16, 0U);

Best regards,

Salas.

Hi @Manuel_Salas ,

I am a little new to this domain and I might be wrong here. However, these files are for A55's Linux kernel. I am trying to control GPIO_IO16 from M7, via Zephyr RTOS. For that, I'll have to move the resource using SM's configuration and header files (mx95evk.cfg, config_scmi.h, config_trdc.h). Please let me know if there is any other way to going about this along with detailed steps that need to be followed.

Thanks,
Deepshika
