i.MX6Q hanging at "Primary CPU switching to normal world boot" #2002

Closed janhieber closed 4 years ago

janhieber commented 6 years ago

Hi! I try to get OP-TEE working on a Wandboard Quad rev D1 (latest). I'm using OP-TEE 2.5.0, Linux 4.13.16, U-Boot v2017.11.

I did the following adaptions: In U-Boot In .config

CONFIG_SYS_EXTRA_OPTIONS="IMX_CONFIG=arch/arm/mach-imx/spl_sd.cfg,MX6QDL,TEE_RAM_SIZE=0x4000000"

In board/wandboard/wandboard.c:dram_init()

gd->ram_size = imx_ddr_size() - CONFIG_TEE_RAM_SIZE;

Linux Enabled TEE stuff

CONFIG_TEE=y
CONFIG_OPTEE=y
CONFIG_ARM_PSCI_FW=y
CONFIG_HAVE_ARM_SMCCC=y

OP-TEE OS Everything in core/arch/arm/plat-imx/platform_config.h seems to be for 1 GiB RAM, do I need changes here? Compilation

make ARCH=arm CFG_PAGEABLE_ADDR=0 CFG_NS_ENTRY_ADDR=0x12000000 CFG_DT_ADDR=0x18000000 CFG_DT=y DEBUG=y CFG_TEE_CORE_LOG_LEVEL=4 PLATFORM=imx-mx6qsabresd CFG_BOOT_SYNC_CPU=n CFG_MX6Q=y CFG_BUILT_IN_ARGS=y
mkimage -A arm -O linux -C none -a 0x4dffffe4 -e 0x4e000000 -d
./out/arm-plat-imx/core/tee.bin uTee

Booting

ext4load mmc 0:1 0x12000000 /boot/zImage
ext4load mmc 0:1 0x18000000 /boot/imx6q-wandboard.dtb
ext4load mmc 0:1 0x20000000 /boot/uTee
bootm 0x20000000 - 0x18000000

Now I get this and than OP-TEE hangs:

What also wonders me is the misaligned cache addr warning. The addresses seem to be OK, Why is that?

Is the problem that I have 2 GiB RAM and the addresses are in the middle of it?

JunOllyLi commented 6 years ago

I have dealt with this problem before. If I remember correctly, it was caused by the Linux kernel trying to turn on SMP. The Linux Kernel from the OPTEE team only supports one core on IMX6. And default SMP code on IMX6 tries to write to some HW which it does not have permission to access. You need to modify the Linux kernel to talk to OPTEE OS to turn on the other cores.

Sorry I cannot remember all the details about what to change anymore.

@janhieber Did you disable CAAM in kernel dts? Could you enable earlyprintk and see where it crashes in kernel side?

janhieber commented 6 years ago

Yes I did disable CAAM, I'm not sure but I also compiled the kernel without CAAM I think. I'll disable SMP and check if that works, thanks!

I shall also have a look at how the kernel is compiled when building with OP_TEE/build...

Thanks!

MrVan commented 6 years ago

It maybe that you do not have the psci code for secondary cores. I use psci, but that code have not open source. I’ll finalize and public that later.

juppin commented 6 years ago

For me it is working. I use optee_os, optee_client and optee_test 3.0.0. U-Boot 2017.11 and Linux Kernel 4.14.14. Also SMP with 4 cores but my board has only 1 gb ram.

All tests are passed without errors

@MrVan @janhieber Are the following kernel configs for CAAM and SMP not needed ? And how to enable earlyprintk and see where it crashes in kernel side inside qemu emulation session ?

Besides, what about outer-cache ?

I do not understand why need to disable CAAM which is Cryptographic Accelerator and Assurance Module

As for enabling earlyprintk for qemu inside extlinux.conf or conf.mk , which of the following files should I modify ?
