Hello @tangchao90 

I hope you are doing well.

Could you please clarify if you are following the AN14093?

Are you using other method?

Please, if possible share steps to reproduce the issue.

Best regards,

Salas.

my step is below:

1.  repo init -u https://github.com/nxp-imx/imx-manifest.git -b imx-linux-scarthgap -m imx-6.6.36-2.1.0.xml

2. repo sync

3. enter the source directory and

 git clone -b lf-6.6.36-2.1.0 https://github.com/nxp-imx-support/meta-imx-fastboot

4. DISTRO=fsl-imx-wayland MACHINE=imx8ulp-lpddr4-evk source imx-setup-release.sh -b build

5. cd build and 

bitbake-layers add-layer ../sources/meta-imx-fastboot

6. bitbake imx-image-multimedia

after building , i can get image and burnin evk board

.\uuu.exe -b emmc_all .\imx-boot-imx8ulp-lpddr4-evk-sd.bin-flash_singleboot_m33 .\imx-image-multimedia-imx8ulp-lpddr4-evk.rootfs-20250124060345.wic

Hi @tangchao90 

Are you using UUU to flash the image? If so, please use the commands marked as a solutions in this ticket: https://community.nxp.com/t5/i-MX-Processors/How-to-load-Falcon-mode-image-to-emmc-on-imx8mplus-dev-... 

Thanks,

Elena

[tangchao90]

yes,  I use emmc flash and the command

.\uuu.exe -b emmc_all .\imx-boot-imx8ulp-lpddr4-evk-sd.bin-flash_singleboot_m33 .\imx-image-multimedia-imx8ulp-lpddr4-evk.rootfs-20250124060345.wic

uuu version is uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.182-0-ga561ed7

[elena_popa]

Hi @tangchao90 

The commands sequence should be:

.\uuu.exe -b emmc_all <default_bootloader> .\imx-image-multimedia-imx8ulp-lpddr4-evk.rootfs-20250124060345.wic

.\uuu.exe -b emmc <default_bootloader> <falcon_mode_bootloader>

The first uuu command writes the wic image using the default bootloader.

The second uuu command writes the bootloader with falcon mode enabled (<falcon_mode_bootloader>) using the default bootloader.

For easiness, you can take the default bootloader from here: https://www.nxp.com/webapp/Download?colCode=L6.6.36_2.1.0_MX8ULP&appType=license

Thanks,

Elena

[tangchao90]

oh , i understand you!  the <default_bootloader> is build without meta-imx-fastboot!

thank you

now my imx8ulp starts up with falcon image

[tangchao90 · Accepted solution]

my steps is below

1.  repo init -u https://github.com/nxp-imx/imx-manifest.git -b imx-linux-scarthgap -m imx-6.6.36-2.1.0.xml

2. repo sync

3. enter the source directory and

 git clone -b lf-6.6.36-2.1.0 https://github.com/nxp-imx-support/meta-imx-fastboot

4. DISTRO=fsl-imx-wayland MACHINE=imx8ulpevk source imx-setup-release.sh -b build

5. cd build and 

bitbake-layers add-layer ../sources/meta-imx-fastboot

6. bitbake imx-image-full

but my imx-boot-imx8ulpevk-sd.bin-flash_singleboot_m33  file size is 1224KB

i download from  https://www.nxp.com/webapp/Download?colCode=L6.6.36_2.1.0_MX8ULP&appType=license imx-boot-imx8ulpevk-sd.bin-flash_singleboot_m33 file size is 1806KB

so my steps is not ok?
