Build FIT image for IMX8MNano

vinothkumars — Sat, 30 Jan 2021 11:39:46 GMT

Dear NXP,

I am looking for guide/release notes or user guide to build fit-image.

fitimage - Kernel+DTB+Initramfs

Is there any configuration to be done to build FIT-Image for IMX8Mnano platform ?

Is there any bitbake command to build FIT-Image for IMX8Mnano platform ?

Hi I able to create the FIT image,

fitImage-linux.bin--5.4-r0-evk-20210130123338.bin

Will you please tell me how to flash this image on target ?

UUU does not have direct command to flash FIT image.You can try to refer UUU.pdf and write the FIT image into address.

This is resolved by increasing loadaddress as per image size,
