PBI on flexbuild_lsdk1712

Hello everyone.

I have been trying to perform this task for several days:

Target:

I am working with the LS1043a board. I want to generate a Boot from SD for my platform. I would also like to insert a PBI command in the Boot (command to disable cores). To generate the boot I am using flex-builder, in particular flexbuild_lsdk1712. I saw from the documentation Layerscape Software Development Kit 17.12 Documentation, Rev. 0, 02/201 that it is possible to make the file firmware_ls1043ardb_uboot_sdboot.img with the following command: flex-builder -i mkfw -m ls1043ardb -b sd -B uboot.
I have already done such a thing using the latest version of flex-builder: flexbuild_lsdk2108
In fact, this link describes in detail all the steps necessary to obtain this result.
I want to do what I did with flexbuild_lsdk2108 with flexbuild_lsdk1712 as well.
I do this because I need to generate the boot from SD with U-Boot 2017 on it

What have I done:

Here is the list of things that I did step by step to be able to generate the file x with the PBI of disabling the registers inside:
Download flexbuild_lsdk1712 builder for ubuntu 16.4 from Layerscape SDK NXP

Run the following linux commands:
$ tar xvzf flexbuild_lsdk1712.tgz
$ cd flexbuild
$ source setup.env
We download all the necessary files, including u-boot, with the following command:
$ flex-builder -c u-boot -m ls1043ardb

Once all the files necessary to compile the image file have been downloaded, we proceed to enter the PBI command onls1043ardb_pbi.cfg file.ls1043ardb_pbi.cfg is located in: packages/firmware/u-boot/ board/freescale/ls1043ardb

The file modified with the addition of the core disable PBI command looks like this:
#Configure Scratch register
09570600 00000000
09570604 10000000
#Alt base register
09570158 00001000
#Disable CCI barrier tranaction
09570178 0000e010
09180000 00000008
#USB PHY frequency sel
09570418 0000009e
0957041c 0000009e
09570420 0000009e
#Core DIS
09ee0094 0000000e
#flush PBI data
096100c0 000fffff
In which the command to disable the cores is: 09ee0094 0000000e
The old u-boot compiled files are deleted, which are located in the following folder: build/firmware/u-boot/ls1043ardb/

The following commands are executed:
flex-builder -c u-boot -m ls1043ardb -b sd
flex-builder -i mkfw -m ls1043ardb -b sd -B uboot
the last command generates me the following file: firmware_ls1043ardb_uboot_sdboot.img

Problem:

Question:

Where can the problem be?

Thank you very much for your availability.

I am attaching my created firmware_ls1043ardb_uboot_sdboot.img file

Your procedure looks reasonable, please deploy the firmware image on SD card with the following command.

dd if=firmware_ls1043ardb_uboot_sdboot.img of=/dev/sdb bs=512 seek=8

Note:/dev/sdb is SD device name on your host PC, bs is the block size of your SD card.
