imx8: emmc image bootup failing in imx8mq-evk

[vsuneja63]

I am flashing custom image in imx8mqevk in eMMC (16GB) by uuu tool. Flashing completed successfully but image not booting up. Does any configuration required for the eMMC? Here are the bootup logs:

Hi vipul,

By default, u-boot wants to boot system from tftp, so you can see that u-boot tried to connect ethernet. use print command to check environment varibles, please! then you will know configurations for booting system from eMMC. for example, run mmcboot etc.

Have a nice day!

Hi,

Thanks!

i tried changing mmcroot, added below lines in imx8mqevk.conf file also but same issue.

UBOOT_CONFIG ??= "emmc"
UBOOT_CONFIG[emmc] = "imx8mq_evk_config,sdcard"

Here are the printenv outcome, can you suggest something on this.

Hi,vipul,

mmcboot=echo Booting from mmc ...; run mmcargs; if test ${boot_fdt} = yes || test ${boot_fdt} = try; then if run loadfdt; then booti ${loadaddr} - ${fdt_addr}; else echo WARN: Cannot load the DT; fi; else echo wait for boot; fi;

the configuration is used to boot from emmc.

so run the command should boot from eMMC; if u-boot can't find fdt file, you can set fdt_file to correct dtb file's name. in u-boot, default setting is " fdt_file=fsl-imx8mq-evk.dtb "

=> run mmcboot

Try it please!

Hi,

Thanks!

I tried the same but looks like after flashing image mmcblk0p doesn't have partition. Tried setting dtb file also.

u-boot=> run mmcboot
Booting from mmc ...
** No partition table - mmc 0 **
WARN: Cannot load the DT

Is there any tool other than UUU for flashing in emmc?

Hello vipul,

>>Is there any tool other than UUU for flashing in emmc?

No, there is not.

 In demo image, there is script named uuu.auto, you can use it to program images into eMMC on board, command is like below:

uuu uuu.auto

Then all images will programmed to board.

Hi,

Thanks!

I could flash image in emmc via sd card. Issue resolved!
