IMX8MM Android10 SD Boot failure state LOCK

jianfeichang — Tue, 08 Dec 2020 07:09:19 GMT

hello，I use imx8mm android10，I only modified the SD card pins，uboot-imx/arch/arm/dts/imx8mm-evk.dts：

369 &usdhc2 {
370 pinctrl-names = "default", "state_100mhz", "state_200mhz";
371 pinctrl-0 = <&pinctrl_usdhc2>, <&pinctrl_usdhc2_gpio>;
372 pinctrl-1 = <&pinctrl_usdhc2_100mhz>, <&pinctrl_usdhc2_gpio>;
373 pinctrl-2 = <&pinctrl_usdhc2_200mhz>, <&pinctrl_usdhc2_gpio>;
374 //cd-gpios = <&gpio1 15 GPIO_ACTIVE_LOW>;
375 cd-gpios = <&gpio2 12 GPIO_ACTIVE_LOW>;//add cjf
376 bus-width = <4>;
377 vmmc-supply = <&reg_usdhc2_vmmc>;
378 status = "okay";
379 };After compiling uboot, burn the image to the SD card：sudo ./fsl-sdcard-partition.sh -f imx8mm /dev/sdb

Could you tell us are you using the reference board or the board you design by yourself? And which andorid10 are you using?

I used my own design board, referring to the IMX8mm EVK LPDDR4。it is android-10.0.0_2.5.0_image_8mmevk.tar.gz，Just a change in the SD card pin。

Now I have the same problem with the official image，emmc is ok，Sd card prompts lock error。android-10.0.0_2.5.0_image_8mmevk.tar.gz imx8mm lpddr4 sd 32G EMMC16G。

android 9 is ok。linux 4.14.98 is ok。emmc and sd。

One more question：

Burn the image using uuu_imx_android_flash.bat，windows7/10 and ubuntu，There will be temporary files that cannot be deleted automatically and need to be manually deleted。 C:\Users\cjf\AppData\Local\Temp ，ubuntu ls /tmp/

The controller connected to the SDcard slot is set to work with Wi-Fi expansion card in Android10.0.0_2.5.0 demo image, it does not support to access SDcard.

so basically, if the dtbo image support Wi-Fi expansion card, then the images cannot boot up from SD card.

This android-10.0.0_2.3.0 version should be work. You can have a try.

You need to download the source and porting your wifi to your board.

You can not use the demo images supply in our website, it's for the reference board.
