Hello everyone.
My goal is to get my LS1043a board to boot by SD and starting the system by shutting down cores 1, 2 and 3.
Once the system is up and running, i would like to see from uboot that such cores are disabled.
To do this I have to create a custom boot via flexbuilder.
The procedure I performed is the following:
/home/flex/Downloads/flexbuild_lsdk2108/components/firmware/rcw/ls1043ardb/RR_FQPP_1455
/home/flex/Downloads/flexbuild_lsdk2108/components/firmware/rcw
And run the linux $ make command, to compile all the RCWs
/home/flex/Downloads/flexbuild_lsdk2108/build/firmware/rcw
/home/flex/Downloads/flexbuild_lsdk2108/build/firmware/atf
/home/flex/Downloads/flexbuild_lsdk2108/build/images
flex-builder -i mkfw -m ls1043ardb-b sd
firmware_ls1043ardb_sdboot.img
firmware_ls1043ardb_sdboot_secure.img
linux_LS_arm64_signature.itb
lsdk2108_yocto_tiny_LS_arm64.itb
rootfs_lsdk2108_yocto_tiny_arm64.cpio.gz
sudo dd if=firmware_ls1043ardb_sdboot.img of=/dev/sdb1 bs=512 seek=8
I use a USB adapter to insert SD card into my PC.
I am running Ubuntu 20.04 through a virtual machine.
The writing seems to have been successful.
But when I try to boot from SD (set de DIP switches for SD boot), I don't see anything on the console.
I don't see Uboot starting.
there is something wrong with this procedure ?
Below is the link to the drive folder in which there are all the .bin files of interest and the modified RCW file

Thank you for your answer.
Now the boot starts and I can see u-boot.
To be sure the cores have been disabled, I went to read the contents of the DCFG CCSR COREDISR register by running the following command on u-boot
md 0x1ee0094 1
But I read the following value 0x0e000000
I shouldn't be reading 0x0000000e
