QorIQ LS1043ARDB SDK 2.0 u-boot verified boot

Hi,

I am actually implementing u-boot verified boot described in u-boot documentation (doc/uImage.FIT/beaglebone_vboot.txt) and would like to know what should be the kernel.its I should use. I tried these two files but none of both seems to work. As a matter of fact, I put wrong syntax in the files so that the build should fail but it does not.

1)  ~/QorIQ-SDK-V2.0-20160527-yocto/sources/meta-freescale/recipes-fsl/images/fsl-image-kernelitb/kernel.its

2) ~/QorIQ-SDK-V2.0-20160527-yocto/build_ls1043ardb/tmp/work-shared/ls1043ardb/kernel-source/kernel-ls1043a-rdb.its

Any implementation guide using the SDK would be appreciated.

Thanks in advance.

J.W.

Thanks,

I managed it to work. One way to do so is to build the FIT image manually.

1) Build the kernel with fsl-image-minimal

2) Move the standalone kernel image, the dtb and the its in a new directory.

3) Follow the u-boot documentation to sign images (doc/uImage.FIT/beaglebone_vboot.txt) and build the FIT image with corresponding files.

4) Rebuild u-boot in the QorIQ SDK with verified boot options enabled.

5) Load bianries on the target and test.

If kernel source code is not installed, install kernel source code first using the following command sequence:

bitbake -c cleansstate virtual/kernel

bitbake -c patch virtual/kernel

 

See .its file using the following path:

QorIQ-SDK-V2.0-20160527-yocto/build_ls1043ardb/tmp/work/ls1043ardb-fsl-linux/linux-qoriq/4.1-r0/git


Have a great day,
