Hi.

When iMX8QM-MEK boots, the following message is output on the console.

What does that mean?

and How can I solve it?

By changing the pin assignment in scfw and excluding the target pin from the assignment, the error disappeared.

Thank you @b45499 .

The BSP I'm using is Android-11.0.0_2.6.0.
I downloaded it from i.MX 8QuadMax/QuadPlus Multisensory Enablement Kit | NXP Semiconductors.

The image of M4 has not been changed.

 

See [iMX8QM-MEK] LPUART4 settings - NXP Community for my steps.

I found the following two descriptions in pads-imx8qm.h (/kernel_imx/include/dt-bindings/pinctrl).
#define IMX8QM_M40_GPIO0_00_DMA_UART_RX IMX8QM_M40_GPIO0_00 2
#define IMX8QM_M40_GPIO0_00 9

In other words, it turns out that "9" is like the ID of "M40_GPIO0_00" given by NXP.

It seems that the setting of "M40_GPIO0_00" has failed, but this error has not been resolved yet.
