Hi hackers, Is trustzone working on exynos 4412 platform? I have selected the follow item in Fiasco config menu: * Platform Timer (Multi-core timer) * Use ExtGic * Execution Model (TrustZone normal side) But it stop at early stage. Same result for Execution Model (Standard mode). but no message for Execution Model (TrustZone secure side). If the trustzone is disabled in u-boot, the 'Standard mode' works fine. ----- booting log ----- OK U-Boot 2010.12-00000-g8d816e8-dirty (May 06 2013 - 19:38:10) for Exynox4412 CPU: S5PC220 [Samsung SOC on SMP Platform Base on ARM CortexA9] APLL = 1000MHz, MPLL = 880MHz DRAM: 1023 MiB PMIC VERSION : 0x00, CHIP REV : 3 TrustZone Enabled BSP BL1 version: 20121128 Checking Boot Mode ...
