OPTEE header parse error on STM32MP135F-DK

[JKim.2]

Hello,

I'm changing the DDR3 size from 512MB to 1GB on the STM32MP135F-DK board. The modifications were done as below. After that, I met the OPTEE header parse error. Compilation and updating software on board was conducted according to the ST wiki. ( https://wiki.st.com/stm32mpu/wiki/How_to_cross-compile_with_the_Developer_Package ) Please help me to solve this problem.

change from 0x20000000 to 0x40000000

• stm32mp135f-dk.dts in Linux Kernel, U-Boot, TF-A, and OP-TEE
• stm32mp135f-dk-fw-config.dts in TF-A
• stm32mp13-ddr3-1x8Gb-1066-binF.dtsi in TF-A (DDR_ADDRMAP6 0x0F070707 ==> 0x07070707)
• conf.mk in OP-TEE

Thanks.

Hi @JKim.2 ,

Sorry to come late in this thread. 

We will soon release a wiki page addressing modification to be done while changing DDR Size. 

It described reduction from 512 to 256MB but I'm sure it can be relevant for the opposite. 

Please let me know if it help

Hi Olivier,

Thank you for the news. I'm looking forward to it.

Best Regards,

[debugging]

Have  the same problem on a custom board. we had to change the memory to 0x400000 in OPTE DT to avoid OPTEE to stop compilation. If this was/is known issues, why is there no information ? Also, please advice a link to this the page of this picture ? Tried to Google some some the text in it,but can't find it. Was it recently added somewhere ?

In my case there is no 135f.dts file  (using STM32MP157AAA3), Modifying the .mk file it keep gets overwritten back to the original value at the build. (perhaps it uses it from the dts file)

Just found a WARNING message in the OPTEE wiki, but this warning is not in the TF-A WIKI 

https://wiki.st.com/stm32mpu/wiki/How_to_configure_OP-TEE

Enable TF-A configuration switch STM32MP1_OPTEE_IN_SYSRAM=1 for both TF-A BL2 and TF-A FIP images.

enable OP-TEE configuration switch CFG_STM32MP1_OPTEE_IN_SYSRAM=y

Question #1:

if this build switch is needed for TF-A for STM32MP15 why is it not in TF-A configuration wiki ?   Was this wiki just added recently ? Can't help wonder how to have noticed the big warning blocks.

Question #2

CFG_STM32MP1_OPTEE_IN_SYSRAM=y . set this to y in build/conf.mk but it always changes back to "n" it seems the build/.conf get generates at build time, but from which file  ? Where to set this option to "y", in which file ?  and This should contain a typo as well, it should be CFG_STM32MP1_OPTEE_IN_SYSRAM ?= y , correct ?

Question #3

Why does CubeMX not generate the correct values in the DT ? for the memory and reservation?

Question 4:

Added the reservation in the DTS, but OPTEE errors with that it cannot parse the line:

st,protreg = <TZC_REGION_S_RDWR 0>;

Copied the section from :

https://github.com/STMicroelectronics/optee_os/blob/3.16.0-stm32mp/core/arch/arm/dts/stm32mp135f-dk.dts

.dts:45.18-19 syntax error
FATAL ERROR: Unable to parse input tree

Found the reason because it needed the defintion in #include <dt-bindings/soc/stm32mp-tzc400-macro.h> Why was that not mentioned ?

Question 5:

It seems that OPTEE build does not generate the correct header information, it it did there would not be an error from OPTEE to find the OPTEE data, correct ? For this, changed the entry point in optee-header_v2.bin manually to the one that OPTEE seems to expect as listed in the error. For example change two bytes FE00 to DE00. but this causes another error. How to calculate the correct value in the header ?

ERROR: Parse optee image failed.
ERROR: OPTEE header parse error.

----

I don't like the wiki's that keep changing on the fly.  Why not publish a PDF/book of the wiki and update when there is a change ? Quite old skool, but its so much better for version changes and tracking !

ST posted the WIKI on Step 12

https://wiki.st.com/stm32mp/index.php?title=How_to_configure_a_256MB_DDR_mapping_from_STM32_MPU_Distribution_Package

but it did not solve my problem

https://community.st.com/t5/stm32-mpus-products/stm32mp15-eco-5-0-0-bl2-stuck-at-loading-bl32/m-p/590432

and appears to be related to

https://community.st.com/t5/stm32-mpus-products/op-tee-error-tzc-permission-failure-on-new-v5-0-0-sdk/td-p/584339

And questions 1 to 4 above still stand. (Item 5 was probably a mistake i changing the header manually)

[JKim.2]

Hi Olivier,

Thank you for posting the guidance. ( How to configure a 256MB DDR mapping from STM32 MPU Distribution Package - stm32mpu ) After the compilation, I need to copy the result files to SD card. Btw, according to the tutorial in ST wiki (  How to cross-compile with the Developer Package - stm32mpu ), I found the same "fip-stm32mp135f-dk-optee.bin" should be copied to the sdb5 partition three times as below. Could you please confirm the destination partition is correctly noted in the tutorial? It's hard to understand how it can work. Thanks.

Best Regards,

Jeff

[Bernard PUEL]

Hello Jeff, the FIP contains OP-TEE (incl. OP-TEE Devicetree), u-boot and u-boot devicetree. So as soon as you have updated all your modification in the final FIP. You only need to flash it one time.

If you are using Makefile.sdk to generate your component, every time you build, the FIP will be generated again with the new component changes.

You can use dd as you did to update your board or the cubeprogramer or the cubeIDE (build + update).

[Bernard PUEL]

For the partition names, you can use: "ls -l /dev/disk/by-partlabel/" on your host Machine to verify the right names.

[debugging]

I ran in the not in reserved area issue again.  Always compiled with DEBUG=1. After removing that an all other DEBUG command line options for OPTEE and TF-A, finally BL32 Extra 1 (id 8) and 2 (id 9) were loaded.

Both TF-A and OPTEE need STM32MP1_OPTEE_IN_SYSRAM=1 on the  build command line and OPTEE CFG_STM32MP1_OPTEE_IN_SYSRAM=y CHANGED (not added) in the optee conf.mk file .

This solution worked for me. YMMV. (hope did not confuse anyone else).

[JKim.2]

Hello Bernard,

According to the initial error log, I set reserved-memory for optee as below. However, the bootlog still shows "TEE load address @ 0xde200000" with the TZC permission failure. Enabling STM32MP1_OPTEE_IN_SYSRAM didn't help. Please review the below boot log.

optee-os-stm32mp-3.16.0-stm32mp-r2/core/arch/arm/dts/stm32mp135f-dk.dts

reserved-memory {
#address-cells = <1>;

ranges;

optee_framebuffer: optee-framebuffer@fd000000 {

st,protreg = <TZC_REGION_S_RDWR 0>;
};
};
