u-boot.imx and SPL IMX6UL

Is is possible to use u-boot.imx and SPL at the same time? I tried it many times but it failed.

When i use u-boot-ivt.img instead of u-boot.imx everything works fine (signed u-boot-ivt.img + signed SPL).

My question is actually what image do i need for hab encryption and why can't i combine u-boot.imx+ SPL

Comparison:

cat u-boot-ivt.img.log
Image Name:   U-Boot 2019.01-rc1-00780-g0371a0
Created:      Wed Jan 16 21:23:34 2019
Image Type:   ARM U-Boot Firmware with HABv4 IVT (uncompressed)
Data Size:    462784 Bytes = 451.94 KiB = 0.44 MiB
Load Address: 17800000
Entry Point:  00000000
HAB Blocks:   0x177fffc0   0x0000   0x0006f020

cat u-boot.imx.log
Image Type:   Freescale IMX Boot Image
Image Ver:    2 (i.MX53/6/7 compatible)
Mode:         DCD
Data Size:    466944 Bytes = 456.00 KiB = 0.45 MiB
Load Address: 177ff420
Entry Point:  17800000
HAB Blocks:   0x177ff400 0x00000000 0x0006fc00
DCD Blocks:   0x00910000 0x0000002c 0x00000004

As you can see the Entry point for u-boot-ivt.img is 00000000 and there are no DCD blocks, if i am not wrong in need

those values to the encryption.

I hope somebody can help me out.

Hi Omar

nxp does not support i.MX6UL SPL  in its releases, may be useful

to check third party tutorial about i.MX6 SPL boot

ventana/bootloader – Gateworks

Where can i find the releases from nxp? I used the bsp from meta-freescale to build my images. How can i install u-boot.imx on the imx6ulevk?
