STM32 MPUs

Hi，allI noticed that the ethernet driver stm32mp13xx_hal_eth.c in the STM32CubeMP13_V1.1.0 already supports PTP, When will STM32CubeMP2 package be available, and since the STM32MP2 series supports TSN, whether EST(IEEE 802.1Qbv) and FPE(IEEE802.1Qbu) functions are supported in the driver? @MWB_CHa ,I see that PTP function is added by you, so do you know the relevant information?

Hello,I am working on a schematic for the STM32MP257FAI3 and the documentation seems to be inconsistent and/or incomplete regarding which ports go where with the built-in Ethernet switch.  The data sheet says ETHSW has three ports in which the "The third port is connected internally to the ETH1 controller". This implies that ETH2 and ETH3 are the external RGMII interfaces.The "Getting Started with ... Hardware Development" guide says "ETH1 is either ETH1 direct or ETHSW port2" (it is unstated, but combined with the data sheet this would be an internal connection), and ETH3 there is a note "ETH3 is ETHSW port1".  There is no such note for ETH2, so this omission implies that ETH2 is not connected to ETHSW (or perhaps it is connected through STNoC??).  The block diagram in the data sheet also matches this notion.In any case, it would be very helpful if there was a table that show what is connected to what when ETHSW is enabled.  At this point I need to know what pins t

Dear All,   I have been working on communicating with LCD module by 3 wire, 9bits SPI. Firstly I implemented it by gpio. I can communicated with LCD module by 3 wire, 9bits SPI. But we encounter problem in total time in sending pixel data by SPI. We're using 320X240 LCD. It takes around 18 seconds to transfer all pixel data to LCD module. Therefore I need to find another way to reduce time in communicating with LCD module. We think that SPI driver will be faster than using GPIO. But I wonder how to send each data in 9 bits. If anyone have experience about SPI 9 bits, please advise.  

I have been working with the Secure boot and OPTEE integration in my Custom board. All the repositories are maintained in kirkstone and I don't want to switch them to scarthgap yet. OPTEE works fine with non-secure system when trusted boot is disabled; everything works fine.But when Trusted boot is enabled the size of BL2 increases by 20KB in the sysram and due to this reason the BL32 (OPTEE) when loaded in the sysram Panics the system because it doesn't find enough room to reside itself in the sysram.Here are the error logs. INFO: Memory size = 0x40000000 (1024 MB) INFO: DFU USB START...

Hi, I'm trying to change the value of the register RCC_RDLSICR (RCC reset duration and LSI control register, address offset 0x144). I need to change the Minimum Reset Duration value.In all power management/low power handling manuals for STM32MP15x lines the documentation says that you can change the registers value, but I can't find HOW I can achieve that. I can write them in dts? inside u-boot? please I need clarifications about that. NOTE: I'm using a custom STM32MP153 board with OpenSTLinux distribution on it.  Thanks a lot

Hello, I hope you are doing well. I have developed a custom PCB with the STM32MP153AAB microprocessor. The process followed  almost all the steps in the wiki for the STM32MP157F-DK2 discovery kit, however, some pins had to change due to the custom design and the fact that the 153 family has less available pins. We have modified the devicetree for the TFA, U-BOOT and KERNEL but the process stops in the TFA when it tries to start the SDRAM with the following output: We are using the STPMIC1APQR in order to provide all the tension levels for the MPU, RAM and other peripherals (similar to the STM32MP157F-DK2). The following images show the schematics for our own custom STPMIC1APQR design:    We measured the voltage levels, and it shows that the buck2 is not providing any voltage, the same happens for all the LDOs that source the power supply for the RAM. Reading the STPMIC1APQR  datasheet, we observed that the  voltage levels are the d

We had a custom board with STM32MP135F series MPU on it, we just rolled out a new revision because we didn't connected PDR pin and it wasnt able to start after reset. But everything was booting correctly and all systems were working. Now in our new revision, we just fixed the PDR and added the emmc but when I try to boot with all debug and log levels maxed, I get this error on my console and nothing else;    PANIC at PC : 0x2ffee107 Exception mode=0x00000016 at: 0x2ffee107    I'm not sure this is TF-A output because all debug logging is allowed. It seems like its panicking at the end of SYSRAMI suspected my clock settings but the parts has not been changed, its the same crystal and same device tree settings should work.Also I'm able to boot with UART/USB mode and connect to device with UART (USB also doesnt work in this mode somehow), I can even load DDR utility binary with STM32Programmer CLI, but after the code downloads to target I loose conn

Hello all,I was trying to build Linux kernel and push into my STM32MP135F-DK. For this, I was following the steps below link (Modify, rebuild and reload the Linux® kernel):https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP135x-DK/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Modify,_rebuild_and_reload_the_Linux%C2%AE_kernelNothing seemed wrong to me until "5.4. Reboot the board" step. After I rebooted the board, only the ST logo appears for a while, then it disappears and a black screen appears for a few seconds, then the ST logo appears again. This loop continues constantly and never switches to other screens (Linux splash screen, Weston desktop, GTK demo launcher).I have no idea why I experienced such a thing since everything seemed correct until the reboot step. I wondered if I had pushed the wrong device tree in the "5.2. Push the device tree into the board" step in the link above (since I was using STM32MP135F-DK, I pushed the stm32mp135f-dk.dtb one). But I am not su

Hi, We are in a new project (first time with embedded Linux and device tree's in general) and i want to config my device (STM32MP151CAA3 on a custom board) to boot from FMC NAND flash (MT29F8G08ABACAH4-IT:) and i am having some trouble with the device tree configuration. i am following the guidelines from the ST wiki regarding this: https://wiki.st.com/stm32mpu/wiki/FMC_device_tree_configuration. The base settings i understand and the wiki refers to the following boot configuration settings (which refer to ONFI settings again) https://wiki.st.com/stm32mpu/wiki/STM32_MPU_ROM_code_overview#Flash_memory_boot  From here i don't understand how to add the ONFI data to the ROM code, do i need to add these settings in the device tree somewhere or are these settings uploaded via CubeProgrammer. I also don't know if i need to add the necessary partitions on the NAND flash to the device tree or not. The 'STM32 MPU ROM code ' page refers to the MPU flash mapping page which explains the n

Hi MP2 Champ ! Is there a table that summarizes the power consumption data of STM32MP25 series by use case?I can find data for MP1 series, but I can't find simple data for MP2 series except datasheet. Thanks.Best Regards, Jack

Hi, I recently got this board and learning about it. My demo application will be for Cortex-A7 core with linux.I need to make application which takes input from user say I have Menu with 5 choices and user can provide the choice number. How can I configure this? I am looking for any examples if available. Do I need to configure any pins and re-build the kernel?Any help will be appreciated, Thank you.

I create new STM32 project for STM32MP131AAG3 with baremetal. An error occurs when build the project.../../Drivers/CMSIS/Device/ST/STM32MP13xx/Include/stm32mp131axx_ca7.h:166:4: error: redeclaration of enumerator 'RESERVED_111' I fixed the enumerator name to RESERVED_112 by myself to build.RESERVED_111 = 111, /*!< reserved */RESERVED_112 = 112, /*!< reserved */ Is there a plan to apply this bug fix to the STM32CubeMP13 codebase?

Hi,we've upgraded our build from 5.15 to 6.1 and now the OS does not get the mac address set in uboot environment through a script. If i check the environment i can correctly see the ethaddr set via printenv. Is there something i can do in kernel config or ethernet driver?

Hello,I am currently engaged in a project that involves using TrustZone to securely display an image on the STM32MP135F-DK. I'm facing several challenges, especially in configuring the framebuffer for secure display purposes:1. Running the 'hello_world' Example: I am experiencing issues with running the TrustZone 'hello_world' example from OP-TEE on the board. I tried to get the OP-TEE version that supports STM32MP1, compile OP-TEE, and copy the output OP-TEE trustzone's hello_world binary to the board. But it cannot be directly executed on the board.2. Triggering TrustZone: After installing the SDK for STM32MP135F-DK and recompiling the kernel and drivers as per the instructions from the wiki, I am unsure of how to proceed with testing the OP-TEE 'helloworld' example. Should I compile it within the SDK and then transfer the binary to the board?3. Secure Framebuffer Configuration: I noticed that the dts file for STM32MP135F-DK already defines a secure framebuffer. Does it provide inter

Hello,I would like to set up the PMIC for the MP13 series using Baremetal. The provided PMIC-related documentation appears to be related to Linux. Is there any documentation or example available for using it with Baremetal?Thank you.

Hi st team, I am using the STM32MP135f-DK board and I want to enable CANFD drivers. First I checked if the CAN drivers are enabled in menuconfig using:  bitbake virtual/kernel -c menuconfig (everything has been selected) Then I went to ~/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Distribution-Package/build-openstlinuxweston-stm32mp1/tmp-glibc/work-shared/stm32mp1/kernel-source/arch/arm/boot and modified the files as follows: stm32mp13-pinctrl.dtsi (configured the pins PG1 (pin 16 CN8) for TX and PG3 (pin 18 CN8) for RX) fdcan2_pins_mx: fdcan2_mx-0 { pins1 { pinmux = <STM32_PINMUX('G', 1, AF9)>; /* FDCAN2_TX */ bias-disable; drive-push-pull; slew-rate = <0>; }; pins2 { pinmux = <STM32_PINMUX('G', 3, AF9)>; /* FDCAN2_RX */ bias-disable; };};fdcan2_sleep_pins_mx: fdcan2_sleep_mx-0 { pins { pinmux = <STM32_PINMUX('G', 1, ANALOG)>, /* FDCAN2_TX */ <STM32_PINMUX('G', 3, ANALOG)>; /* FDCAN2_RX */ };}; tm32mp135f-dk.dts added: &m_can2{ pinctrl-names = "

I am trying to interface DAC for the STM32 MP157D-DK1 board I have. I am just curious does the board even support DAC. I dont see any mention of that in the datasheet. That is the only option that I can select when I do DAC Enable for M4 Cube in cube programmer. In NVIC settings only option is EXTI line 9 interrupt available for me to select.

I'm having a challenge moving changes from our Developer Package to our Distribution package. We've modified device trees using CubeMX for our board and have all the changes for TF-A, optee, u-boot and the kernel working in the Developer Package.
