SCMI protocols not active

AVazquez · ‎2023-03-13

Hi all.

I am using a stm32mp157c-dk2 with lastest OpenSTLinux Distribution (4.1.0) trusted.

In log I saw messages about SCMI driver and a series of protocols not actives.

[    0.150587] arm-scmi firmware:scmi: SCMI Notifications - Core Enabled.
[    0.150709] arm-scmi firmware:scmi: SCMI Protocol v2.0 'ST:' Firmware version 0x0
[    0.289178] arm-scmi firmware:scmi: Failed. SCMI protocol 23 not active.
[    0.412876] arm-scmi firmware:scmi: Failed. SCMI protocol 21 not active.
[    0.424756] arm-scmi firmware:scmi: Failed. SCMI protocol 19 not active.
[    0.428615] arm-scmi firmware:scmi: Failed. SCMI protocol 17 not active.

I should care about this messages?

Why are these protocols not active?

What are these protocols?

Thanks!

Hi @AVazquez ,

For an overview of SCMI :

Did you get those traces on the provided starter package for DK2 or on a custom version?

Hi @AVazquez ,

I don't reproduce the same at my end with stm32mp1-openstlinux-5.15-yocto-kirkstone-mp1-v22.11.23\images\stm32mp1\flashlayout_st-image-weston\trusted\FlashLayout_sdcard_stm32mp157c-dk2-trusted.tsv

Can you double check and provide details reference of the binaries you are using + complete boot log ?

Thanks

Olivier

Hi, @Community member

Yes, no problem.

I am using the lastest version (4.1.0) and I am using the follow script:

./create_sdcard_from_flashlayout.sh ../flashlayout_st-image-weston/trusted/FlashLayout_sdcard_stm32mp157c-dk2-trusted.tsv

This generates the file FlashLayout_sdcard_stm32mp157c-dk2-trusted.raw and I put this file on sdcard.

I have repeated the test and see the same traces with the fail message. Complete kernel trusted traces.

Curiously, these traces don't appear if I use the optee version. Complete kernel optee traces

Thanks!
