MX6SL and HAB u-boot

Problem booting an IMX6SL board in HAB closed mode.


I can succesfully boot via the mfg tool using a signed image.


But the installed u-boot signed image just hangs.


last attempt at a CSF file looks like:--


Version = 4.1
Hash Algorithm = sha256
Engine = DCP
Engine Configuration = 0
Certificate Format = X509
Signature Format = CMS

[Install SRK]
File = "../../cst-2.3.3/crts/SRK_1_2_3_4_table.bin"
Source index = 0 # Index of the key location in the SRK table to be installed

[Install CSFK]
# Key used to authenticate the CSF data
File = "../../cst-2.3.3/crts/CSF1_1_sha256_2048_65537_v3_usr_crt.pem"

[Authenticate CSF]

[Install Key]
# Key slot index used to authenticate the key to be installed
Verification index = 0
# Target key slot in HAB key store where key will be installed
Target index = 2
# Key to install
File = "../../cst-2.3.3/crts/IMG1_1_sha256_2048_65537_v3_usr_crt.pem"

[Authenticate Data]
# Key slot index used to authenticate the image data
Verification index = 2
# Address Offset Length Data File Path
Blocks = 0x877ff400 0x00000000 0x00051c00 "boot.bin"


The defconfig has the following HAB entries:



and is pretty much identical to the mfg config apart from the MFG=Y


I have tried with Engine = Any and Engine = SW but to no avail.

The u-boot works on an Open config machine, and I did not see any hab_status errors before the board was closed.

A similar setup fir a mx6ul board is working without problems.
