I'm new to STM32CubeMX and have difficulties finding out how to map all OCTOSPIM_P2 signals to Port G. I can manually map some signals to Port G (CS, IO[7:4], DQS), but can't figure out how to map the rest.  Any help most welcome!

Hello,I initially implemented TouchGFX on an Nucleo board with an STM32G071RBT6 (128K flash).Currently, I am using a custom PCB with an STM32G071R8T6 (64K flash), but I did not change the MCU model in STM32CubeIDE.However, despite the build analyzer showing a flash usage of 90K, the application appears to be running normally.The images are stored in SPI flash, but I expected the application to fail due to exceeding the MCU’s 64K flash limit.What could be the reason why the application is still functioning seemingly without issues?I have attached an image showing the memory usage in the build analyzer.Thank you!   

I'm trying to find out the exact steps to regress an STM32U083 to an erased state after programming it with the OEMiRoT example project and and locking it to RDP2 by the accompanying provisioning.bat script.Will be using STM32CubeProgrammerCLI (or the GUI version at first just to test the steps) for the regression.Something like chapter 10 of the STM32U5 AN5347 would be nice (https://www.st.com/resource/en/application_note/dm00625692-stm32l5-series-trustzone-features-stmicroelectronics.pdf)or like this forum post on U5: https://community.st.com/t5/stm32-mcus/how-to-regress-from-rdp-level-2-to-rdp-level-0-on-the-stm32u5/ta-p/568476Especially the "Disable RDP regression with a password" action in the programmer GUI seems very counter-intuitive to do for an RDP2 level locked chip, as if you would deliberately brick it by disabling the regression (no password in level 2 = bricked). Is this always a safe step? Because as long as the level is 2, the password will be necessary to regress

It's strange that I got this pic before click the get latest: But when I try to download it, it changes to 1.17.0, funny?

[VERSION]: MCWB v6.3.2[TOOL]: STM32CubeMX v6.13.0, STM32CubeIDE v1.11.5[BOARD]: STEVAL-PTOOL1V1[PROJECT]: STEVAL-PTOOL1V1_6S_SLI've been trying to get this board working with a small BLDC motor but the keeps shutting off the motor output when the speed is brought up a bit.  I tried increasing the current limit in the code (I believe although I'm not certain I'm effectively doing that).I want to see if I can connect a serial port and see messages or use Motor Pilot or Motor Profiler.  The documentation for this board doesn't show a UART port mapped to the external pins.  Can it be done?

I'm developing a low-power device using the STM32WLE5.To reduce power consumption of the peripherals (sensors / display / eeprom) during the sleep of the MCU, all these peripherals are switched off with a P-channel mosfet as shown in this part of the schematicThe enable is driven down by a GPIO when the peripheral is active.To minimize the power consumption of the MCU during sleep, the IO's are configured as Analog inputs. The 1M pull-up resistor keeps the mosfet OFF when it's gate is not driven during sleep of the MCU.But it's not working as expected : when the IO is configured as analog, it's not rising to 3.3V, but remains at 2.5V, too low to properly turn off the mosfet..When I replace the 1M with 330K, it's better, but I'd like to understand why such a strong pull-up is needed ?The GPIO in analog input mode should be very high impedance, same for the mosfet..I could keep the GPIO in output and drive the mosfet gate even when MCU is in sleep, but AN4899 recommends them to be config

Hello,Hello,I'm planning to integrate GPS: GNSS1 and install a web browser on an STM32MP157F-DK2, so I'm looking to add layers.Before adding the layers, I thought it would be a good idea to follow this tutorial:https://wiki.st.com/stm32mpu/index.php?title=STM32MPU_Distribution_Package&sfr=stm32mpuI followed it to the letter.I'm running Ubuntu 20.04 with all the required dependencies:https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP135x-DK/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Install_the_SDKI'm up to 80% of the st-image-weston bitbake when an error message appears:```ERROR: st-image-vendorfs-1.0-r0 do_rootfs: The postinstall intercept hook 'update_mandb' failed, details in /home/atem/Distribution-Package/build-openstlinuxweston-stm32mp1/tmp-glibc/work/stm32mp1-ostl-linux-gnueabi/st-image-vendorfs/1.0/temp/log.do_rootfsERROR: Logfile of failure stored in: /home/atem/Distribution-Package/build-openstlinuxweston-stm32mp1/tmp-glibc/work/stm32mp1-ostl-linux-gnueab

Hello,The datasheet for STM32WB55RG (DS11929, 3.6.1 RF front-end block diagram, page 22) states that the output power is user programmable:"In Transmit mode, the maximum output power is user selectable through the programmable LDO voltage of the power amplifier. A linearized, smoothed analog control offers clean power ramp-up."The figure 5 in reference manual RM0434 shows a Max PA level input to the LDO but I can't find the register to set this value. How do I program the RF transmit power on a STM32WB55 ?Thanks for considering my request.

Dear Experts,I am looking at configuring the CORTEX_M7 section for my custom STM32H743VIT6 based board. Below are the functionalities that I plan to use with the board:a. Sensors' reading via SPI, I2C, b. Communication via UART/USART, USB, Ethernet (LAN8742),c. LwIP and potentially FreeRTOS I would like to have your advice on the disabling / enabling of caches and especially the MPU configuration/settings in case :1. Without external QSPI Flash and external PSRAM,2. With external QSPI Flash and/or external PSRAMI took some look at the STM32H7-LwIP-Examples for the NUCLEO-STM32H743 board  and the following h7_lwip_freertos example but there's certain different in terms of number of MPU regions being used as well as their base addresses, sizes and permissions, etc.Where can I find the information or documentation to correctly configure the above section, please ?Thanks in advance and best regards,Khang

Section 3.20: "It requires a precise 48 MHz clock that is generated from the internal high-speedexternal clock source"So we have "internal external" clock source. ;)

Hey, I am working on Xbee with stm32, and I am getting a big problem while connection.  I am using two Xbee's one is configured as a standard router which is connected to UART1 of the stm32 controller and the other is configured as a coordinator which is connected to the com port of another system through RS485 cable to XCTU. I have to use them in API mode. I have configured both of them in API Mode, now I am able to send API data frame from router to coordinator , but I cant receive API frame from coordinator to router ?  When I send a simple API frame from the coordinator to the router, the router Xbee sends an acknowledgment frame back to the coordinator, but my controller does not receive any frame, I have written the code to receive the complete frame at once using the polling method as well as interrupt method as well as to fetch the data in single-byte also. But it's not working. Data is received up to Xbee but the controller does not receive anything. It stops th

I'm unsure as to how to do this because"STReader stReader = new STReader(); stReader.connect();"Always connects to the same reader - the only sucess i've had so far is by running 2 instances of the program which isn't fit for purpose.Can anybody help?Thomas

I have several NUCLEO-H755ZI-Q boards, the documentation says that the clock coming out from STLINK should be 25MHz but I meassured STLK_MCO and found an 8MHz signal... on SB72 to be more precise.The sticker on the boards sayNUCLEO-H755ZI-QNUH755ZIQ$AT3I was having issues when using HSE as a clock source, because I was configuring it to 25MHz as stated in the documentation and as it defaults to in CUBEMX... The issues went away when I set it to 8MHz.Under the microscope X1 crystal shows 25.000.Is there something to configure on STLINK to get the 25MHz?Could the board be fake?

Hi all, I am configuring FDCAN3 on the STM32H723 to receive data for a specific ID, but I'm encountering an issue. Here's what I've done so far: We have configured the FDCAN filter as follows:     Filter_config_def.IdType = FDCAN_STANDARD_ID; Filter_config_def.FilterIndex = 0; Filter_config_def.FilterType = FDCAN_FILTER_MASK; Filter_config_def.FilterConfig = FDCAN_FILTER_TO_RXFIFO0; Filter_config_def.FilterID1 = 0x7E8; Filter_config_def.FilterID2 = 0x7E8; Filter_config_def.RxBufferIndex = 0;     Then, we applied the filter using:     if (HAL_FDCAN_ConfigFilter(&hfdcan3, &Filter_config_def) != HAL_OK) { Error_Handler(); }     However, I am still receiving all IDs, such as 0x90, 0x7E8, and 0x110, even though I only expect 0x7E8. I would like to call the callback function only when data with ID 0x7E8 is received. Here is the relevant configuration for FDCAN3:     hfdcan3.Instance = FDCAN3; hfdcan3.Init.FrameFormat = FDCAN_FRAME_FD_

Hello,I am trying to set up the 14 cell GUI using the C4MLIT1, ISOSPI1, and BMS63EN boards. At this point in time, I am only interested in the logging functionality and just want to use the demo as it comes.I have the hardware set up in centralized configuration, with just a single BMS63EN connected to 14 cells via the BMSHOLD cell holder (~56 V total). When I start the GUI, the serial port connects, but no data appears.Could someone advise on whether I have understood the broad steps correctly, starting from having AutoDevKitStudio installed and GUI project imported?Move GUI .exe to desktop.Connect ISOSPI1 to MCU as per the board view schematic, shown by clicking "SPC58EC 4M board view".

Hello, STM32F407G DISC-1, STMCubeIDE I configured timer3 for generating PWM signal which is 1kHz with %70 duty cycle. I connected its pin(PB4)  to input capture channel(PA1). I use default HSI clock 16Mhz.  I can measure this PWM signal using logic analyzer. However, when I try to calculate its duty cycle with timer5 input capture mode, I always receive those values firstRise = 15559, secondRise = 31300. My expected value, difference of them should have been 100.Since one tick is 10us , and the period the PWM signal 1ms. 100 / 100000 = 1ms. What did I misunderstand? What might be the problem?

Hello,I have a NOR SPI flash connected to single SPI interface of a H75x MCU and want to use the highest possible SPI frequency for data read. The core clock is 400MHz, so I can chose between 50 and 100MHz.According to the data sheets the "Clock low to output valid" time tv of the IS25WPxxx is 7-8ns, the H7 setup time is 1-2ns. This means the half period (SPI clock low time between falling and rising edge) must be at least 10ns. Assuming high and low pulse are the same, this means the max. clock is 50MHz in this simple calculation, which is not considering signal transmission delays, signal rise/fall times and switching voltages.I found out that most flash have implemented a "NORMAL READ" and a "FAST READ". Both differ in the max. SPI clock, for example 80MHz for READ and 166MHz for FAST READ transfer. Unfortunately, looking at the timings, I do not understand why the FAST READ frequency is twice the READ transfer frequency.The meaning of tv is explained here:This means that data on SO

Hi,I have a problem during creation of Semaphore in STM32CubeIDE. When I create a semaphore (dynamic or static) and add it to register view then.... nothing happens. I discovered that issue when in fact this mutex behaves as it wouldn't be created ever (taking it, results in  time out). In exactly same way, I do create other semaphores/mutex in the system and all fine. I was making tests and observed:dynamic/static creation has no effectheap is sufficient, creation in dynamic mode successfully allocates memory for itthe order or creation matters, just like there would be a lock on max 6 sempahores. When I move the semaphore to initialize it first, it works, but the still the last semaphre suffers. Any ideas?ThanksMarcin 

Hello,I am currently working on a custom board based on the STM32MP1. In my research, I found that flashing firmware over JTAG is not supported for the STM32MP1 series. Instead, we need to rely on USB or UART for flashing purposes.I came across this related issue on the forum: Flashing STM32MP1 Custom Board Over JTAG.Given this, I am concerned about the security implications of using USB for flashing firmware. Specifically:What security measures can be implemented to prevent unauthorized access or flashing through USB?Is it possible to enforce authentication during the USB boot and firmware flashing process?Are there recommended techniques to encrypt the firmware or restrict access to certain boot modes?And if I use the UART for flashing, then how can I do that? Which combination of boot mode selection switch should I use? Is there any specific documentation for flashing firmware using UART?I would greatly appreciate any guidance or best practices to enhance security when using USB as
