STM32 MPUs

I have two STM32MP157C-DK2 dev boards, they still have the demo software on it.They collected a lot of dust, over the past years.The problem is the 3d cube demo slowing down after days.After a reset it is fast again. Perhaps a memory leak?Because it needs a reset every day or maybe every hour, I never was willing to start developing software on it.I'm cleaning up, and I am about to throw these kits in the trashbin.But, what's the undelying problem? Is there a solution to keep de kits running stable and at full speed anyway?

Hi! I wonder if it's possible to use OpenCV on STM32MP2 and configure so the neural networks use the NPU for faster classification and detection. Thanks

Is there a way to increase code size which is used on M4 MCU? I saw some memory regions in device tree, but it is not clear how to do a change. Any info will be appreciated.Best regards,Nenad

Hi everyone, I was finally able to get to the kernel and use the shell using the sd card (yay!). However, we want to boot from the emmc (sd card was for dev purposes but we want only emmc) and I am running into an issue. Here is my boot log from booting on emmc after flashing with DFU:   NOTICE: CPU: STM32MP131D Rev.Y NOTICE: Model: STM32MP1 LED Controller - openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06 INFO: PMIC version = 0x21 NOTICE: Reset reason (0x1035): INFO: Power-on Reset (rst_por) INFO: FCONF: Reading TB_FW firmware configuration file from: 0x2ffe0000 INFO: FCONF: Reading firmware configuration information for: stm32mp_fuse INFO: FCONF: Reading firmware configuration information for: stm32mp_io INFO: Using EMMC INFO: Instance 2 INFO: Boot used partition fsbl1 NOTICE: BL2: v2.10-stm32mp1-r1.0(debug):lts-v2.10.5-dirty(7c229848) NOTICE: BL2: Built : 16:19:31, Jun 28 2024 INFO: BL2: Doing platform setup INFO: RAM: DDR3-DDR3L 16bits 533Mhz INFO: Memory size = 0x

Please help me add support for USB-UART converters of the CP210x and CH341 series on the STM32MP157F-DK2 board. I expect to see ttyUSBx, but no new devices appear after connection. I am using the Distribution Package, and in the kernel configuration, I have activated the following settings: # USB port drivers # CONFIG_USB_SERIAL=y # CONFIG_USB_SERIAL_CONSOLE is not set CONFIG_USB_SERIAL_GENERIC=y CONFIG_USB_SERIAL_SIMPLE=m # CONFIG_USB_SERIAL_AIRCABLE is not set # CONFIG_USB_SERIAL_ARK3116 is not set # CONFIG_USB_SERIAL_BELKIN is not set CONFIG_USB_SERIAL_CH341=m # CONFIG_USB_SERIAL_WHITEHEAT is not set # CONFIG_USB_SERIAL_DIGI_ACCELEPORT is not set CONFIG_USB_SERIAL_CP210X=m But when connecting a CP210x- or CH340-based converter to any of the four USB-A ports on the board, I only get the following in dmesg:  [1619.270102] usb 1-1.3: new full-speed USB device number 4 using ehci-platform At the same time, I can see my adapter when running lsusb: Bus 001 Device

Hello,I have a custom board with the STM32MP257FAK processor. I am having issues booting into u-boot from emmc. I can boot into u-boot fine using dfu-util over usb. But once I program in fsbl, ssbl, and meta data into the emmc and try to boot from it I get a error with the metadata partition. See log below.Any ideas what could cause this error?

Hello,to retrieve the temperature in the M4 domain I use the documentation RM0436, page 1571 (description) and DS12505Rev6 page 209 (characteristics)Q1: what adc resolution is to be used to be compliant to the reference values (calibration values) that are to be read from address 0x5C00525C?Q2: I am using Vref=2.048V. Can I scale the calibration values by the factor 2048 / 3300?Q3: At the address 0x5C00525C I read TS_CAL1 = 12192 (adc value @30°C) and TS_CAL2 = 16270 (adc value @130°C). Is this a reasonable / correct reading?Q4: the formula on page 1571 (RM0436) gives as a result not a temperature but an adc value (".... + TS_CAL1"), though it is supposed to return a value in °C. Is the formula correct?Q5: So the values TS_CALx_TEMP are [°C] and the values TS_CALCx are raw adc values? Anyway: Is there an example for the coprocessor M4? I was not able to create one with th Cube MX tool...Thanks!

Hi,I am compiling a yocto custom layer, I am using this layerspoky/meta-poky \ poky/meta-yocto-bsp \ meta-openembedded/meta-oe \ meta-openembedded/meta-python \ meta-st-stm32mp \ custom-image \I was able to connect the LBEE5KL1DX Murata module to wifi via STA, however, I would like to use switch to the AP mode, I followed the steps in the post https://wiki.stmicroelectronics.cn/stm32mpu/wiki/How_to_configure_a_WLAN_interface_on_hotspot_mode After that, i am able to see the AP when I look in a smartphone, but after logging with the password configured, I see the message "IP configuration failure " on my smartphone.One thing I see suspicious is the inet when i run the command "ifconfig"Another thing i see weird is when i run the "networkctl status wlan0" command, specifically the Network File variable I also tried executing the bash script from a repository and it didn't work either https://github.com/STMicroelectronics/meta-st-openstlinux/blob/dunfell/recipes-sa

HiI have STM32MP157F-DK2 board and I am following StarterPackage Wiki document.(https://wiki.st.com/stm32mpu/index.php/STM32MP15_Discovery_kits_-_Starter_Package) I am following wiki and my STM32MP157F-DK2 board is not entering DFU mode. Here are the steps I tried to enter DFU mode. DeepSwitch is set to off and I am using 5V 3A charger for power. I connected OTG cable and inserted microSD into slot, turned on power and pressed Reset button. However, when I execute 'STM32_Programmer_CLI -l usb' command on PC, only 'No STM32 device in DFU mode connected' response is returned. What did I miss? I tested it on Windows PC and Ubuntu 20.04 PC respectively. Any help is very appreciated, thank you,

We're moving to the latest scarthgap release (v24.11.06) of the ST distro (building from yocto).  We have a custom board.Generating the device tree from STM32CubeMX 6.13.0 no longer seems to define the pinctrl settings in the device tree?I clicked the option to migrate the .ioc file.Apart from a few whitespace changes, the device tree differs only in terms of missing pinctrl configuration.  This doesn't seem right to me, I don't see where else that is being defined and will be required for our pin muxing.  The STM32M4 firmware base code also output is missing configuration for the GPIO?Why are there no Pinctrl definitions any more?  Is there a configuration, or is STM32CubeMX broken?  I've reinstalled it and the packages.(we migrated .ioc file and regenerated the device tree successfully several times for mickledore)

Hello,I encountered a problem with optee that I could not resolve due to a misunderstanding of debug information.During boot up the board, I get the following debug logSpoiler (Highlight to read)...F/TC:0 0 __clk_enable:1195 Clock 192 has been enabledD/TC:0 0 probe_driver_node:550 element: stm32-rtc on node rtc@5c004000 initializedF/TC:0 0 probe_driver_node:543 Probing stm32-iwdg on node watchdog@5a002000F/TC:0 0 pager_deploy_page:1469 Mapped 0x30023000 -> 0x2fffa000F/TC:0 0 pager_deploy_page:1469 Mapped 0x30056000 -> 0x2ffea000F/TC:0 0 pager_deploy_page:1469 Mapped 0x30021000 -> 0x2fffd000D/TC:0 0 gic_it_set_cpu_mask:410 cpu_mask: writing 0xff000000 to 0x349218b4D/TC:0 0 gic_it_set_cpu_mask:412 cpu_mask: 0x3000000D/TC:0 0 gic_it_set_prio:426 prio: writing 0x1 to 0x349214b7D/TC:0 0 dt_driver_device_from_node_idx_prop:370 Property resets missing in node watchdog@5a002000F/TC:0 0 __clk_enable:1195 Clock 58 has been enabledD/TC:0 0 iwdg_wdt_get_version_and_status:528 Watchdog is

Hello,I am currently using Linux kernel version v5.15-stm32mp-r2.tar.gz and U-Boot version v2021.10-stm32mp-r2.tar.gz for my project based on the STM32MP family. I have recently upgraded the Linux kernel to linux-5.15-stm32mp-r2.2.However, I am unsure which U-Boot version is compatible with linux-5.15-stm32mp-r2.2. I tried using U-Boot version v2022.10-stm32mp-r2 with this kernel, but encountered the following error during compilation: Error: arch/arm/dts/.stm32mp157c-ccb-mx.dtb.pre.tmp:1478.1-6 Label or path sram not found FATAL ERROR: Syntax error parsing input tree Check /home/vivekb/workspace/source/NGACEM-269/SSB-buildroot/output/build/uboot-custom/arch/arm/dts/.stm32mp157c-ccb-mx.dtb.pre.tmp for errors make[4]: *** [scripts/Makefile.lib:336: arch/arm/dts/stm32mp157c-ccb-mx.dtb] Error 1 make[3]: *** [dts/Makefile:44: arch-dtbs] Error 2 make[2]: *** [Makefile:1173: dts/dt.dtb] Error 2 make[1]: *** [package/pkg-generic.mk:293: /home/vivekb/workspace/source/NGACEM-269/SSB-buildr

I'm encountering difficulties while attempting to connect and debug my STM32 microcontroller, and I'm seeking guidance from the community. I have erased the full chip flash memory and uploaded my code but suddenly I start getting these error messages,Error Messages:1.

I'm using en.stm32cubemp2-v1-1-0.zip plus patch file en.stm32cubemp2-v1-1-1.zip I'm trying to build CM0PLUS_DEMO for STM32MP257x-EV1 for the cortex-M0 core.I got planty of errors when trying to build it with STM32CubeIDE Version: 1.17.0 Build: 23558_20241125_2245 (UTC):Failed to generate command line.reason: Unknown target. I'm reviewing the 'How to use the Cortex-M0+' document for any advise on how to build the example but it does not give any expecial advise so I assume I have to use CubeIDE:https://wiki.st.com/stm32mpu/wiki/How_to_use_the_Cortex-M0%2B#Memories_RIF_configuration_exampleOther examples for the Cortex-M33 build correctly. Thanks in advance, Hector.    

Hi,I try to use libpq library to connect postgresql from STM32MP157. It works on my computer. When I want to implement it to the board it doesn't work. I include path with .h but if I link libraries path I have that error.What I should do. Thanks in advance

Hi everyone,The stm32mp1 use SDMMC2 as default emmc controller. Now, I need use SDMMC1 to connect emmc flash. And I saw the OTP need changed. Bud I am confuse about IOs of SDMMC1. Does it also need setting some OTP bits to pinmux CK, CMD, D0?This picture show need change bit to chose SDMMC1.This picture is confused me. When I use SDMMC1, is it need configure CMD, CK,D0 to default pinmux on SDMMC1? If it is needed, where to configure those?

Hi Guys,Please I facing problem to have a QT application fitting the DSI screen,it sounds like it is 400x240 and not 800x480. I`m probably missing something on QTor on the STM32MP157C-DK2.Can someone please help-me to correct the resolution and how to use it landscape ?Thanks [ ]

Hey there,I'm trying to boot my custom stm32mp153c board using the new Scarthgap version of the meta-st-stm32mp layer. I had it working with the previous combination of optee 3.19 / kernel 6.1 (See this post). Ater some adaptation of device trees and my layer I've got OPTEE booting and loading the kernel, but unfortunately it stops right at the kernel loading. Any ideas what I might be missing or how to debug it further? Starting kernel ...D/TC:0 psci_cpu_on:172 core 1, ns_entry 0xc0301a40, state 0I/TC: Secondary CI/TC: Secondary CPU 1 switching to normal world bootD/TC:0 pwr_scv_handler:56 PWR service: write 0x0 at offset 0x28D/TC:0 pwr_scv_handler:56 PWR service: set 0x3f at offset 0x20I/TC: Reserved shared memory is disabledI/TC: Dynamic shared memory is enabledI/TC: Normal World virtualization support is disabledI/TC: Asynchronous notifications are disabledD/TC:1 0 stat_handle_fault:1740 nfaults 11264 npages 17 (min 16)D/TC:? 0 tee_ta_init_session_with_context:562 Re-open trus

I am trying stm32mp157f-dk2 for learning linux based on starter packageI just got succeed with load example 1 dtb and echo uart operating Anyway so I got checked the extlinux.conf file can control which dtb would be called But I dont know what's happening let me show what i wonder 1. Why stm32mp157c-dk2-extlinux.conf is called?2. Why load stm32mp157c-dk2.dtb? there's not FDT setting in default LABEL I can do with just change conf file in 157c-dk2 for nowBut i want to know how to select conf file Thank you
