Dear all:

I trying to test the Secure Boot (HAB). And HAB is ok now.

iMX6UL + BSP4.1.15_1.0.0

1. But kernel will hang when lcd resolution is 1024x768 (larger than 800x600) and HAB is enabled.

2. kernel boot up sucessfully when lcd resolution is 800x600 (only resolution is changed) and HAB is enabled.

3. kernel always boot up successfully when HAB is not enabled.

Hi Yang

unfortunately L4.1.15 is not more supported as outdated, recommended to try with

latest linux and Code Signing Tool releases described on

Best regards

1. This problem can also reproduced on latest Code Signing Tool releases cst-3.3.1

2. Upgrade to the latest Linux is so heavy work, it is impossible.

Thanks.

How can I know the Release Date and Support time of every BSP-version?

We will request support by sales.
