AM62L: eMMC booting issue through .wic file

Ninad J S

Part Number: AM62L

Hello Team,

We are trying to boot the AM62Lx board from the eMMC. We are able to successfully flash the .wic image to the eMMC; however, during boot, the board fails to load the kernel and device tree.

Below is the error log observed during boot:

We request your support in providing the correct procedure to flash and boot the AM62Lx from eMMC using a .wic file

Hello,

If you have flashed the WIC image then your Linux Rootfs partition is in the 2nd partition so you would have to run the following commands to boot the Linux.

=> setenv mmcdev 0
=> setenv bootpart 0:2
=> boot

I have clarified in my first response that you need to set the "mmcdev" and "bootpart" env variables before booting the Linux.

Can you please check if the rootfs in your tiny image even contains the Kernel path (/boot/Image) and the DTB path (/boot/dtb/ti/k3-am62l3-ig69s-prgjj-04.dtb) that the U-Boot is looking for?

If in doubt, please share the output of the following commands

=> mmc dev 0
=> mmc part
=> ls mmc 0:2 /boot
=> ls mmc 0:2 /boot/dtb/ti

The filesystems looks fine. I see in the boot logs that the uEnv.txt file is loaded. Can you please share the contents of this file? I would like to make sure if this uEnv.txt file is interfering with the env variables.

# This uEnv.txt file can contain additional environment settings that you
# want to set in U-Boot at boot time.  This can be simple variables such
# as the serverip or custom variables.  The format of this file is:
#    variable=value
# NOTE: This file will be evaluated after the bootcmd is run and the
#       bootcmd must be set to load this file if it exists (this is the
#       default on all newer U-Boot images.  This also means that some
#       variables such as bootdelay cannot be changed by this file since
#       it is not evaluated until the bootcmd is run.

This looks okay. How about the output of the following command?

=> printenv

The "args_mmc" in your env differs from the default

args_mmc=setenv bootpart ${mmcdev}:${mmcpart}; run finduuid;setenv bootargs console=${console} ${optargs} root=/dev/mmcblk${mmcdev}p${mmcpart} rw rootfstype=${mmcrootfstype}

Since you are setting bootpart as part of running the args_mmc, this overwrites the bootpart var set with "setenv bootpart 0:2".

Can you try the following commands

=> setenv mmcdev 0
=> setenv bootpart 0:2
=> setenv mmcpart 2
=> boot

Yes, This works

Is there any method to reduce the size of default image .wic file ?

Thank you .

I am not the subject matter expert for the latest query. In my knowledge, there are a lot of packages, utilities, and so on built with the default WIC image. You may remvoe the ones you don't have the need for to reduce the size. There is Base WIC image as well built with Yocto much smaller in size than the default.

Please create a new thread if you need the support for the latest query.

Hello ,

I had flashed uboot binaries using DFU and then followed the steps to flash the .wic file .
tiny image .wic file is successfully flashed . But after observing the uboot binaries arent from the .wic file which i flashed these are from the previous binaries which i flashed through dfu tool.
i tried replacing the binaries using ums 0 mmc 0 command binaries are replaced but while booting these binaries arent used .
How to update the uboot binaries (tiboot3.bin tispl.bin u-boot.img ) which are used for booting ?
If there is any log or steps for reference to check the flashing and booting from .wic file ?

Please share the logs of the procedure you followed for this?
