Hi,
I am using a JODY-W263-00A WiFI+Bluetooth module in iMX 8DXL custom board.
For this module, I have configured in dts file as follows:
pinctrl_usdhc2_gpio: usdhc2grpgpio {
fsl,pins = <
IMX8DXL_QSPI0B_DATA0_LSIO_GPIO3_IO18 0x00000021
IMX8DXL_QSPI0B_DATA2_LSIO_GPIO3_IO20 0x00000021
IMX8DXL_ADC_IN5_LSIO_GPIO1_IO13 0x00000021
IMX8DXL_ADC_IN0_LSIO_GPIO1_IO10 0x00000021
>;
};
pinctrl_usdhc2: usdhc2grp {
fsl,pins = <
IMX8DXL_ENET0_RGMII_RXC_CONN_USDHC1_CLK 0x06000041
IMX8DXL_ENET0_RGMII_RX_CTL_CONN_USDHC1_CMD 0x00000021
IMX8DXL_ENET0_RGMII_RXD0_CONN_USDHC1_DATA0 0x00000021
IMX8DXL_ENET0_RGMII_RXD1_CONN_USDHC1_DATA1 0x00000021
IMX8DXL_ENET0_RGMII_RXD2_CONN_USDHC1_DATA2 0x00000021
IMX8DXL_ENET0_RGMII_RXD3_CONN_USDHC1_DATA3 0x00000021
>;
};
With the above configuration, my WiFi module is not getting detected. When checked, the SD clock is 0Hz. So, I have changed the pad register values as below:
pinctrl_usdhc2_gpio: usdhc2grpgpio {
fsl,pins = <
IMX8DXL_QSPI0B_DATA0_LSIO_GPIO3_IO18 0x00000040
IMX8DXL_QSPI0B_DATA2_LSIO_GPIO3_IO20 0x00000040
IMX8DXL_ADC_IN5_LSIO_GPIO1_IO13 0x00000040
IMX8DXL_ADC_IN0_LSIO_GPIO1_IO10 0x00000040
>;
};
pinctrl_usdhc2: usdhc2grp {
fsl,pins = <
IMX8DXL_ENET0_RGMII_RXC_CONN_USDHC1_CLK 0x00000040
IMX8DXL_ENET0_RGMII_RX_CTL_CONN_USDHC1_CMD 0x00000040
IMX8DXL_ENET0_RGMII_RXD0_CONN_USDHC1_DATA0 0x00000040
IMX8DXL_ENET0_RGMII_RXD1_CONN_USDHC1_DATA1 0x00000040
IMX8DXL_ENET0_RGMII_RXD2_CONN_USDHC1_DATA2 0x00000040
IMX8DXL_ENET0_RGMII_RXD3_CONN_USDHC1_DATA3 0x00000040
>;
};
In this case, I am getting an SD clock of approximately 400kHz. But I am getting the below error continuously:

What is this error? What I am doing wrong here? What pad register value I should provide here?
I have attached the boot log here. Can anyone please help me on the above?
