Example for optee:make -f $PWD/../Makefile.sdk all DEVICETREE=stm32mp157a-board-mxAn  error occurs but it stlll generates message with outpfolder and a message that the output files was completed.This happens when the device tree is not found it with errors in the device tree. It still generated the bin files in optee/deploy folder letting the user with the impression that everything went fine.what we would like is to have a makefile just to build for a one board that stops and gives a clear message that something went wrong, with a return value for non zero so that it also can be integrated in a build script.There was one was to easy check on error by adding > <output>to the make command. it then just shows a the error and stop message.make -f $PWD/../Makefile.sdk DEVICETREE=stm32mp157a-board-mx allmake[1]: Entering directory '/media/user/H3D2P1/Tools/STM32MP1/STM_ECO_5.0.0/Developer-Package/stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21/sources/arm-ostl-linux-g

Besides , scmi_vdd_sub is only defined in mp135f dsti files and reference the PMIC resources which this board does not have. only way to fix it was changing the reference from scmi to usb_vdd . Is this correct?     

https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/plat/stm32mp1.rstmentions to build u-boot and optee first before TF-A:Building u-boot raises an error:Missing stm32mp157a-board-mx-fw-config-optee.dtb file in folder: $FIP_DEPLOYDIR_FWCONF or '$FIP_DEPLOYDIR_ROOT/arm-trusted-firmware/fwconfig'When building TF-A it fails but it does generated this dtb. After copying the dtb to the FIP_artifact folder, and then running u-boot again , the TF-A builds as well.Is this how it's supposed to be ?

These are the steps in chronological order to be able to build the files for a custom board. This seems very convoluted and easily confusing. I this process correct  ? The issues normally are not found with the STM board because all the pre-build files are already in the fip  and other source folders, but for a custom board they are not, hence the issues.Build sequence:=================* Install the SDK* SDK source set to the arm toolchain* Extracted all the sources and applied the patches* Copied the device tree files from CubeMX to the respective folders.* Updated the makefiles.sdk with the the new board name.* Added the device tree file name to the makefiles in fdts and dts sub-folders (TF-A / u-boot)* Set the $FIP_DEPLOYDIR_FIP' and $FIP_DEPLOYDIR_ROOT* Deleted all the custom board files under $FIP_DEPLOYDIR_ROOT that were built before during trial (& error)Steps and issues encountered in chronological order:1. Build u-bootmake -f $PWD/../Makefile.sdk all UBOOT_CONFIG

Quite simple, I try to search for  a variable and when I click search even though I KNOW it's in the project. The window disappears and nothing is done. Is this a bug or Is my search wrong? I'm trying to search the entire project.This is quite frustrating. (See Below)  Thank you

how we can putt our video in the stm32mpu video playback folder  and how we can play this video ?

 STM32MP157AAA  custom board with DRAM, SD- EMMC, USB and UART , Discrete power( no PMIC) . The board uses discrete oscillators for HSE and RTC, so they are set as Crystal OSC for both in CubeMX USB, UART are correctly configured (same as the default peripheral settings). DRAM is correctly setup based on the used DRAM chip. In .config the PMIC options is disabled and legacy power enabledThe CubemX settings were verified by the SOM manufacturer as being correct. This board has run a previous version of the ECO system without problems.TF-A uses SCMI but if the file #include "stm32mp15-scmi-u-boot.dtsi" is included, errors occur.To fix some other CubeMX generated dts file errors:a. Add a file stm32mp157a-<board>.dsti file in the main dts file. (which CubeMX did not add as an include). This fle is empty.b.. Add a binman entry to the stm32mp157a-<board>.dsti. Thee definition was found in stm32mp15-scmi-u-boot.dts and if not included u-boot fails with a message tha

I'm trying to use the TIM internal peripheral as an events counter on an STM32MP15. I have the ETR pin connected to a line generating pulses. When I tried to configure the trigger in STM32CubeMX,I was unable to select the ETR trigger when TIM1 was connected to Linux, only when connected to the M4 core.Is there no linux driver capable of running the TIM internal peripheral in this mode?https://wiki.st.com/stm32mpu/wiki/TIM_device_tree_configuration seems to indicate that `st,stm32-timer-counter` can be used as an external events counter. Do I simply need to manually create the device tree setup? If so, what do I need to do to set it up?

When generating u-boot an error occurs: stm32mp15-scmi-u-boot.dtsi:135.1-6 Label or path scmi not found. Following the steps in the OpenSTLinux 5.0 workshop document to update the device tree files.  It mentions to include an scmi.dtsi file for u-boot for the specific board. Is there any more information how to do this? This is a custom board with an STM32MP157AAA3 using legacy power. (regulators not PMIC) and this board worked fine with a previous ECO system but in ECO 5.0.0 SCMI was introduced.  

I have several projects already configured for STM32MP157C and I don't want to have to build them all over again if I can help it. Also, my team is asking I not move the Ecosystem (but if that is my only answer I will.)

Why are there different device trees for optee, TF-A, u-boot and linux kernel ? Since the hardware does not change between the boot stages, isn't it possible to consolidate it into one dts generated by CubeMX .The different boot modules consume the data form one dtb ? This will help to reduce maintenance and avoiding errors in compilation of the different modules .

Hello.I have a question about STM32CubeProgrammer.I'm going to use the STM32 system image in Raspberry Pi.How do I flash an STM32 image on an SD card that will be mounted on a Raspberry Pi board?I want to use STM32 program in Windows environment as much as possible.The following are the methods and results I thought of.1. Fit formatted SD card into Raspberry Pi and connect to Rsap's micro5 pin and Windows PC, and USB from 'STM32CubeProgrammer' >>> Program not recognized 2. Connect with Windows PC using SD Card Reader >>> Program not recognized

I am trying to configure some HW IP to work with the M4 core of the STM32MP157, I can find only the GPIO already assigned to other IPs ont he development Kit.How to configure GPIO's and configure interrupts related to SPI DMA from the M4 side?Attached is a screenshot for the available GPIO's on CubeMX. 

We are using the STM32MP157AABx device in our project and updating to the v5.0 Ecosystem and STM32CubeMX v6.9.0.When we generate our device tree files, the optee-os device tree tries to include:#include "stm32mp15xxab-pinctrl.dtsi"This file is not found in the optee-os-stm32mp v3.19.0 source tree referenced in the v5.0 Ecosystem.I have had to manually modify the dts to include:# include "stm32mp15xxac-pinctrl.dtsi"This is the closest match, but not equivalent to the number of gpio banks in the AABx package.Is this an issue with optee-os-stm32mp source code, the CubeMX tool, or user error in our configuration?

Hello, I am currently researching about possibilities in STM32MP1 dual core. I am trying to create user program that uses HW Semaphore. I used program from wiki:https://wiki.st.com/stm32mpu/wiki/Hardware_spinlock_overview.and makefile described here:https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Create_a_simple_hello-world_applicationwith including builded linux kernel 5.15.67.But I can't build program, because of numerous errors. I was trying to resolve some of errors by including them hard-coded way into user space program, but I think, that is not the correct way to fix these errors. How to properly build program including kernel files? Is there any include to be included when using kernel files? Or any other makefile switch? See attached files...Thanks for any tips.Some of compile errors:Original post (with less description):https://community.st.com/t5/other-tools-mpu/stm32mp1-build-user-program-with-hwspinlock

Isn't there a script file for generating RAW images for eMMC like the "create_sdcard_from_flashlayout.sh" file for generating RAW images for SD?Also, why is SD memory mapping different from eMMC memory mapping?

Hello, I am currently researching about possibilities in STM32MP1 dual core. I am trying to create user program that uses HW Semaphore. On M4 side is everything clear. But I cannot create program for A7 core. Here is what I think that I suppose to do:- create user program with hwspinlock.h- build corresponding version of linux kernel- include kernel files to makefile.But when I try to make my custom program, i got much errors from kernel source tree.For me, how to properly include hwspinlock framework is not clear from ST wiki or hwspinlock framework documentation.Thanks for any response.
