I am trying to run OPTEE and Linux on a Sabre Automotive with a i.MX6Q. Some questions:
- where can I find and build Linux in order to be aware to run in the Normal world (including OPTEE driver and avoiding all secure accesses)?
- does the latest Linux distro support the PSCI to enable SMP? If yes, where I can find the source code?
Actually I am able to run OPTEE with CFG_BOOT_SYNC_CPU=n and CFG_PSCI_ARM32=y. OPTEE correctly configures the primary CPU and launches the Normal world that gets stuck without printing anything.
I tried 2 different Linux source code:
- linux-imx-imx_4.1.15_2.0.0_ga from the official git linux-imx.git - i.MX Linux Kernel
I built both solutions with the following extra lines in the imx_v7_defconfig:
Does anyone can help me on having a fully working SMP environment with OPTEE?
Thanks a lot in advance
