android-10.0.0_2.5.0_image_8mmevk flashing images to sdcard issue

[wadewu]

Hi NXP team

I am using i.mx 8m mini evk lpddr4 borad to test android-10.0.0_2.5.0_image_8mmevk image .

I find when i using emmc flash this image and boot , everything is fine。

Using sdcard flash this image and boot ,the system will be occurs FirstStageMount::InitRequiredDevices() failed.

But when i using android-10.0.0_2.3.0_image_8mmevk image file to test ，everything is ok。

The dmesg log like below:

my sdcard is 16GB , UUU tool work on win10 and ubuntu 18.04 both .

with uuu command

version android-10.0.0_2.5.0_image 8m evk
emmc -> .\uuu_imx_android_flash.bat -f imx8mm -a -e => System OK
sdcard -> .\uuu_imx_android_flash.bat -f imx8mm -t sd -a -e ->System failed

and i change the version to android-10.0.0_2.3.0_image 8m evk
emmc -> .\uuu_imx_android_flash.bat -f imx8mm -a -e => System OK
sdcard -> .\uuu_imx_android_flash.bat -f imx8mm -t sd -a -e => SystemOK

Please help for this.
Thanks.

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.

I dowlanded "imx-android-10.0.0_2.6.0.tar.gz" and saw the same the problem "init: [libfs_mgr]ReadDefaultFstab(): failed to find device default fstab
". How can i solve it ?

[wadewu]

OK. i got it.

thanks a lot.

[Hakan]

Hi,
I faced the same problem. How did you solved it ?

[Zhiming_Liu]

Hi wadewu

Can you tell me if the images downloaded on our website or made by yourself?

Best Regards

Hello Zhiming:

Thanks for your quick reply.

I just download the website Demo Image , and  test  the programming to eMMC and SDCARD and

Boot.

Hi

Our evk support max sd speed 200MHZ, you use a 200MHZ+ SD. Our default image made for 200MHZ SD card.So you need change source code in \android_build\vendor\nxp-opensource\kernel_imx\drivers\mmc\core\host.c

if (device_property_read_bool(dev, "mmc-hs200-1_8v"))
host->caps2 |= MMC_CAP2_HS200_1_8V_SDR;
if (device_property_read_bool(dev, "mmc-hs200-1_2v"))
host->caps2 |= MMC_CAP2_HS200_1_2V_SDR;
if (device_property_read_bool(dev, "mmc-hs400-1_8v"))
host->caps2 |= MMC_CAP2_HS200_1_8V_SDR;
if (device_property_read_bool(dev, "mmc-hs400-1_2v"))
host->caps2 |= MMC_CAP2_HS200_1_8V_SDR;
if (device_property_read_bool(dev, "mmc-hs400-enhanced-strobe"))
host->caps2 |= MMC_CAP2_HS200_1_8V_SDR;

Hi:

i am download imx-android-10.0.0_2.5.0.tar from website and building.

and modify the \android_build\vendor\nxp-opensource\kernel_imx\drivers\mmc\core\host.c

but this method still does not solve the problem.

i am compared imx-android-10.0.0_2.3.0.tar and imx-android-10.0.0_2.5.0.tar two version of the native code.

i find the two different parts, maybe cause sdcard issue.

\android_build\device\fsl\imx8m\evk_8mm\BoardConfig.mk ln191

+ BOARD_USES_METADATA_PARTITION:=true

+ BOARD_ROOT_EXTRA_FOLDERS += metadata

\android_build\vendor\nxp-opensource\kernel_imx\arch\arm64\boot\dts\freescale\imx8mm-evk.dts

+ metadata{

compatible ="android,metadata";

dev ="/dev/block/by-name-metadata";

type="ex4";

mnt_flags="noatime,nosuid,nodev,discard,sync";

fsmgr_flags="wait,formattable,firsat_stage_mount";

};

maybe this different parts cause.

And now we decided to use the imx-android-10.0.0_2.3.0.tar version development and testing
Thanks a lot.

[Zhiming_Liu]

Or if you will made imx8mm board by yourself.You can design 400MHZ SD interface and add it in dts.
