Boot Issue with IMX6sx board:

Question asked by Dheeraj R on Mar 1, 2018
Latest reply on Mar 8, 2018 by Jas Math

Hi, I am implementing High Assurance Boot in my imx board. However, once I had checked that there were no HAB events, I blew the fuse to enable secure boot. Even though the u-boot and the kernel are booting perfectly fine, the boot process hangs at a particular point (" mmcblk3: mmc3:aaaa SL08G 7.40 GiB
mmcblk3: p1 p2   mxc_asrc 2034000.asrc: mxc_asrc registered). Below is the output that I got:
