my board is
According to the manual,MACHINE ??= 'imx8ulp-lpddr4-evk' but the image can't burn,below is the burn log. when i use branch imx_6.1.55_2.2.0, it can burn and start success,but i want to start quickly in falcon mode

Solved! Go to 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?
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
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
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
oh , i understand you! the <default_bootloader> is build without meta-imx-fastboot!
thank you
now my imx8ulp starts up with falcon image
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?
