Frozen when flashing the image for IMX6DL

[MihanLee]

Hi

I tried to flash the latest image V5.15.32 for the board based on IMX6U7CVM08AC, using Ubuntu 22.04 with the *.wic.bz2 file

But It's frozen, here is the message in verbose mode:

vmuser@vmuser-virtual-machine:/mnt/hgfs/CODE$ uuu -v -b emmc_all u-boot-tagged.imx imx-image-full-imx6dlsabresd-20230131030147.rootfs.wic.bz2

What should I do for it?

[nxpfrankli]

look uboot have not boot at boards, can you check serial port output?

[MihanLee]

Yes, there is nothing output on the serial port. What should I do next?

[MihanLee]

But I flash the old image (4.1.15) with mfgtool is okay. is there some differents between the latest image (5.15.32) and the old one e.g. address?

[MihanLee]

I found the size of old u-boot (4.1.15) is about 367KB, and the latest one is 624KB.

[nxpfrankli]

The size is not problem. Maybe DDR change or some problem, uboot hange before print anything. It need debug uboot. Does it can boot from sd card?

uuu -b emmc old_uboot new_uboot

to check if new_uboot can boot from emmc?

[MihanLee]

I tried to make the SD card as following the guide from NXP to boot, but the unit didn't boot with this image from SD card, which can boot with the old image. bzcat ...wic.bz2 || sudo dd of=/dev/sd.. bs=1M conv=fsync

OTOH, uuu -b emmc <old_uboot> <new_uboot> is also frozen on the same place.

[nxpfrankli]

You need debug uboot.

[MihanLee]

I found some output from serial port using uuu command as you said on Windows.

Ok, how to debug uboot in details?

[nxpfrankli]

you can ctrl-c, then enter console, run fastboot 0

If it works. It should failure auto run fastboot by detect boot from USB. if it is not works, it should usb related function does work.

[MihanLee]

run fastboot 0 or fastboot 0 doesn't work on the console.

=> run fastboot 0                                   
## Error: "fastboot" not defined
=> fastboot 0 
Unknown command 'fastboot' - try 'help'

Your uboot missed some configuration. https://github.com/NXPmicro/mfgtools/wiki/uboot-config-requirement

[MihanLee]

Sorry for late. I added the configuration following the website to .config file, but the uboot v2016.03 doesn't seem to have this fastboot function. but I saw something about SPL but there is something different. It would be good if you could check it for me. The attach is the .config file after make mx6dlsabresd_defconfig.
