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!
Alex
