Hello, NXP Experts

MY custom imx6ull board use NXP offical Linux 5.4.24.

eMMC is connected to 2194000.usdhc(mmc1) , and mmcblk1p2 is my ext4 rootfs partition. 

Below is the log:

 My eMMC node of dts is:

&usdhc2 {
pinctrl-names = "default", "state_100mhz", "state_200mhz";
pinctrl-0 = <&pinctrl_usdhc2_8bit>;
pinctrl-1 = <&pinctrl_usdhc2_8bit_100mhz>;
pinctrl-2 = <&pinctrl_usdhc2_8bit_200mhz>;
bus-width = <8>;
keep-power-in-suspend;
wakeup-source;
non-removable;
no-1-8-v;
status = "okay";
}; 

Everything  return back nornal after re-power on My imx6ll board.

Any suggestion?

@changbaoma How did you solve this issue ?  

Our custom platform is powered with i.MX6 running Yocto-Dunfell with QT(5.15.2) on top of it. The version of Linux kernel used in the platform is 5.4.161. 

The eMMC is connected to the usdhc2(0x2198000). The Linux rootfs and Applications are separated and present in different partition of the same eMMC. 

I'm facing similar issue during reboot test. We have a custom setup which will reboot the machine continuously. I'm seeing this error once in 500 reboots.  

The below messages appear on the serial console which is similar like your case. These messages was observed after the init successfully mounted all the filesystems.. 

sdhci-esdhc-imx 2198000.usdhc: Card stuck in wrong state! card_busy_detect status: 0xe00
mmc2: cache flush error -110
mmc2: tried to HW reset card, got error -110
mmcblk2: recovery failed!

Thanks for your time.
