STM32 MPUs Products and hardware related

Hello,I try to install the distribution package usingrepo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15as described in the wiki, before that made sure to install all packages mentioned in the prerequisites page.The command fails with: File "/home/steffen/Kirkstone/Distribution-Package/openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15/.repo/repo/main.py", line 79   file=sys.stderr)       ^SyntaxError: invalid syntaxI am using Ubuntu 20.1, my python version is 3.8.10Does anyone know what I am missing?Thanks!

Is there a walk-through or example of how to setup secure boot using a custom device tree?As a side note, the following page returns "Permission Error", is that expected behaviour?https://wiki.st.com/stm32mpu/wiki/STM32MP15_secure_boot

Hello,When I tried using fseek and getc functions for my project the MP1 failed to execute their code. The execution stops at lines that contain __IO_acquire_lock(fp) and __IO_need_lock(fp) macros and then terminates in the fseek and getc functions respectively. I also tried other file handling functions such as fread and fwrite and they also fail. Is there anyway to solve this issue?thanks for any answers

Is HAL_UARTEx_ReceiveToIdle_DMA supported on STM32MP15 products? If so is there an example for using it?

I've changed the ownership of the /usr/lib/python3.8 file from root to <myname> but did not solved the problem. Here is the whole error:ERROR: Command execution failed: Traceback (most recent call last): File "/home/gencay/STM32MPU_workspace/openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15/layers/openembedded-core/bitbake/lib/bb/command.py", line 126, in runAsyncCommand   commandmethod(self.cmds_async, self, options) File "/home/gencay/STM32MPU_workspace/openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15/layers/openembedded-core/bitbake/lib/bb/command.py", line 607, in buildTargets   command.cooker.buildTargets(pkgs_to_build, task) File "/home/gencay/STM32MPU_workspace/openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15/layers/openembedded-core/bitbake/lib/bb/cooker.py", line 1581, in buildTargets   rq = bb.runqueue.RunQueue(self, self.data, self.recipecaches, taskdata, runlist) File "/home/gencay/STM32MPU_workspace/openstlinu

Using hexdump /dev/input/event1, you can see the data changes. when I use ts_ test command, "open fbdevice: no such file or directory" will appear. Please help me, I really don't know how to configure it.I am sure that the touch screen monitoring is correct and the data is uploaded correctly.

Hi!   I am trying to enable PTP on STM32F157 DK2 evaluation board.   From my understanding, pps_available should return 1, (if configured correctly).   root@stm32mp1:~# cat /sys/class/ptp/ptp0/pps_available 0 I added "linuxptp" to the image: IMAGE_INSTALL_append += " \ linuxptp \ " I tried to follow the instructions for kernel 4.14: https://community.st.com/s/question/0D50X0000BMG2RoSQL/how-do-i-enable-linuxptp-pps-output   To enable PPS Out, I also patched stm32mp-mp15-pinctrl.dtsi diff --git a/arch/arm/boot/dts/stm32mp15-pinctrl.dtsi b/arch/arm/boot/dts/stm32mp15-pinctrl.dtsi index 236d77e..1e74905 100644 --- a/arch/arm/boot/dts/stm32mp15-pinctrl.dtsi +++ b/arch/arm/boot/dts/stm32mp15-pinctrl.dtsi @@ -160,6 +160,7 @@ ethernet0_rgmii_pins_a: rgmii-0 { pins1 { pinmux = <STM32_PINMUX('G', 5, AF11)>, /* ETH_RGMII_CLK125 */ + <STM32_PINMUX('G', 8, AF11)>, /* ETH_PPS_OUT */ <STM32_PINMUX('G', 4, AF11)>, /* ETH_RGMII_GTX_CLK */

I'd try to follow a step of Installing the SDK in Ubuntu (which is on Raspberry pi 4 Model B 4GB using 26GB SD card)in step 4 Run the SDK installation script I get an Error Error: incompatible SDK installer! your host is aarch64 and this SDK was built for x86_64 hosts.What does it mean and how can I fix itThe main goal of this project is to try to run python (with the library) on STM32MP157F-DK, I have two ideas 1. Follow the step and put it with .py instead of .c (no idea with install a library)2. Install Linux in STM32MP157F-DK and run python on it (need some guild also)So here I have 3 questionThank STM for letting me ask a question here.

Hi there. I'm a professor of computer science at a university in Germany. Our main focus is cyber security. I'm currently looking into exploring options with STM for teaching various security mechanisms and, in particular, interested in using the STM32MP157F-DK2 in classrooms. However, I failed to find any information of how to establish an official contact to STM to discuss various details. If someone could help me out, it'd be greatly appreciated. Thanks a bunch!

I was trying to install OpenSTLinux distribution. I am using ubuntu 20.04 for my host machine. Firstly I init repo with this command:repo init -u <LINK FOR GIT ST OE MANIFEST > -b refs/tags/openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15 then when I try to repo sync. I get following error for almost everythingerror: garbage at end of loose object '543a1d1527d04f297b90ec25658f8dc71f3d0782'fatal: loose object 543a1d1527d04f297b90ec25658f8dc71f3d0782 (stored in /home/gencay/STM32MPU_workspace/openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15/.repo/project-objects/openembedded-core.git/objects/54/3a1d1527d04f297b90ec25658f8dc71f3d0782) is corruptopenembedded-core: sleeping 4.0 seconds before retrying

Hi,I am using Cortex A7 processor GIC V2 for Interrupt handling. I configured GICC and GICD both. I enabled timer and interrupt for timer also. After enabling timer i can able to see pending status in GICD but It is not routing to A7 core. For this what may be the reason?

I need to store a password for encryption in otp registers. I configured device tree in tfa:&bsec{ status = "okay"; secure-status = "okay"; enc_pass: enc_pass@0x170 { reg = <0x170 0x10>; st,non-secure-otp; };};&nvmem_layout {    nvmem-cells = <&enc_pass>;    nvmem-cell-names = "enc_pass";};And in uboot and kernel:&bsec{ status = "okay"; enc_pass: enc_pass@0x170 { reg = <0x170 0x10>; st,non-secure-otp; };};NVMEM is configured in kernel defconfig. I can read and write to set otp register in uboot, but i cant read data in linux.I tried this: hexdump -C -v /sys/bus/nvmem/devices/stm32-romem0/nvmemanddd if=/sys/bus/nvmem/devices/stm32-romem0/nvmem of=/tmp/fileAnd i have that error:stm32-romem 5c005000.efuse: Can't read data32 (-5)hexdump: /sys/bus/nvmem/devices/stm32-romem0/nvmem: Input/output error

Hi,I created a project in Cube-IDE . It is a simple PWM timer Project which planned to be run on A7 processor of the STM32MP1 . I established configurations in Cube-MX and generated the code into the Cube IDE. After that, I moved the .dts file which is in the kernel of the CubeIDE project into the linux kernel arch/arm/boot/dts directory. I am following this video which is a simple PWM timer project(ww.youtube.com/watch?v=XhB0rGLjl_Q&list=PLnMKNibPkDnFeV4sBarnsAtFTg7h6V-9_&index=9). However, in this video conversion of dts to dtb is not shown. The board is booted with a pre-ready .dtb file. I am trying to use the "make dtbs" command it won't work. "No rule to make target. I am also creating an another "build directory" which is located on the arch/arm/boot/build .(Another than the kernel source directory.) Should I copy the .dts file of the project into this build directory? and compile dts to dtb in this directory? And what about the Makefile ? Should I also copy this to that

Hello,Is there a way to access the Tamper or backup registers or the backup sram from the MCU? Or is it physically imposible to do so?Edit:I am still looking for an answer, I just saw in the RCC registers that I can enable BKPSRAM bits to:enable the peripheral for MP (RCC_MP_AHB5ENSETR) and MC (RCC_MC_AHB5ENSETR)enable the peripheral for MP (RCC_MP_AHB5LPENSETR) and MC (RCC_MC_AHB5LPENSETR) in low powerDoes this mean the MCU is able to access the BKPSRAM peripheral?Although I do not see a clock enable for the TAMP, is it the same for the tamper (and backup registers)?Best regards,Andrés

I followed the steps on the below webpage to enable Wireless on my STM32MP1. It would be great to see these instructions added to the wiki.st.com http://trac.gateworks.com/wiki/Yocto/Wireless

As we tested, from word 24 to 32, once write 0xFFFFFFFF ( all 32 bit turn to 1), is there any way to set back to 0x00000000?And same for bit 59 to 95 (free for user)?

I followed ST wiki, success to display OTP by the command:STM32_Programmer_CLI.exe --connect port=usb1 -otp displThen I try to test writing a value to wordid 79 which currently is 0x00000000, and free for user.STM32_Programmer_CLI -c port=usb1 -otp program wordID=0x4F value=0x12345678No thing wrong, command return sucess: I display cmd again, it is till 0x00000000, even reset the board. Any one know what I am missing, please?
