"stm32mp15-no-scmi.dtsi:103.1-5 Label or path dsi not found"

When building a distro for our custom board with a STM32MP153AAC, u-boot-stm32mp fails to build when UBOOT_CONFIG is set to "basic". We would like to do a ddr3 test, this is the reason for the config.

Here is the relevant section from conf/machine/stm32mp1-raichu-v2.conf file

###########################################################################
#
# User machine customization sections
#
###########################################################################
 
# Boot Scheme
# =========================================================================
BOOTSCHEME_LABELS += "trusted"
# WORKAROUND to generate U-BOOT SPL for DDR Tuning tools usage
UBOOT_CONFIG += "basic"

It seems that the dsi block is defined in arch/arm/dts/stm32mp157.dtsi, but we have a stm32mp153, and the device tree generated by CubeMX only includes stm32mp153.dtsi. So obviously, this isn't going to work:

tnx, i have one more question,

If i going through Distribution package installation guide in wiki pages the last minor hot-fixes will be applied?

Olivier GALLIEN · ‎2020-10-05

Hi @SMich.1 ,

No minor hot-fixes release in BSP components are not integrated in Distribution package.

You need to follow instruction in https://wiki.st.com/stm32mpu/wiki/STM32MP15_OpenSTLinux_release_note#Minor_release_updates.

so the tag that fixes this issue is this: v2020.10-rc5 ?

Olivier GALLIEN · ‎2020-10-26

Hi @SMich.1

Sorry for late reply and error in my communication.

Actually v2020.10-rc5 was a wrong reference.

There is no hotfix tag available for this fix on github.

We will integrate it only in next major release.

So you need to apply manually the patch shared in my first comment.
