Emmc UUU flashing of signed ahab images to imx8qxp Evk

[vimalbabu]

We are trying to flash cst signed ahab images to imx8qxp evk. The following are the images in hand

• container with singed uboot ----> flash.bin
• container with signed Image and dtb ---- > Image
• custom-base-image-imx8qxp-20200720055835.rootfs.wic.bz2 , we are using this wic image such that we will replace the uboot and Image with signed flash.bin and Image

Method used to replace uboot 

1. Unzip the wic.bz2, we get custom-base-image-imx8qxp-20200720055835.rootfs.wic
   1. $ bzip2 -vfd custom-base-image-imx8qxp-20200720055835.rootfs.wic.bz2
2. Replacing unsigned uboot with signed flash.bin
   1. $ sudo dd if=flash.bin of=custom-base-image-imx8qxp-20200720055835.rootfs.wic seek=33 bs=1k
3. Using wic command we replace Image with signed Image container
   1. $ wic cp Image custom-base-image-imx8qxp-20200720055835.rootfs.wic:1
4. Flashing wic image to evk
   1. $ sudo uuu -b emmc_all flash.bin custom-base-image-imx8qxp-20200720055835.rootfs.wic

Can you please confirm regarding this method of emmc flashing?

Hello Joanxie,

I want to flash signed image using uuu on imx8qxp. i used sudo uuu -b emmc_all uboot rootfs.wic(this is unsigned image) command everytime. Can you please tell me which command i should used for signed image. name of signed image is now flashed.signed.bin .                              should i try with sudo uuu -b emmc_all uboot(AHAB-ENABLE) Flashed.signed.bin(this signed image include SCFW, SEFW,ATF,uboot)
