Hi, I wanted to read and implement the secure boot on STM32MPU157C-DK2 board. But this page gives permission error. It seems that need to be fixed:wiki.st.com/stm32mpu/wiki/STM32MP15_secure_bootThanks.

Hi everyone,I just bought and received an ST-EVALMKI109V3 + ST-EVAL212V1 according to this webinar. All my software tools seem to be on the latest revisions.I updated the board with the last firmware using this videoMeanwhile I get this error that says it does not know the chip id when I select the MKI212V1 as shown in the screenshot above.I also joined the picture of both boards.Could anyone help me please on that weird issue ?Thanks in advance for your help.Best regardsThierry

Hello everyone once again, i am trying to split the main flash memory (just by using the .ld file) to put in each one a specific code (bootloader, DFU, app), i did what you can see in the image below, but i am not sure why the DFU and FLASH sections are not empty...do i left something else to do? They are not empty:Thanks in advance

Hi everybody,I'm working on NFC tag. I'm using a ANT7-T-M24SR deb board. This one communicates in I2C with an ESP32.First, I tried to read the dev board with a cellphone, and it worked well (URL : st.com)Then I tried to write "Hello world" in the NDEF memory of M24SR and it was written into the memory, and I succeded to read it (only one time) with my cell phone.So now, I have written another message, I think it's well writed into the memory (please see picture below) but I cannot read it with my cellphone.I have one question :After that I closed the I2C session, does I need to do something to reactivate the RF ? Because, by reading the System file, I see that the byte (offset = 0x0006) is sometimes at 0x09 (RF enabled) and sometimes at 0x00.I hope my resquest is enough clear, please find below the different questions/answers between µc and M24SR. 

The Flash of the chip can't be programmed. Mostly the error is that writing the first byte failed. But sometimes it is able to write a few bytes. It even worked like 3 times. The behavior is consistent over STM32CubeProgrammer and ST-Link Utility, and JTAG and SWD. There are some side effects:STM32CubeProgrammer does not report the Flash size correctly. It reports 1M instead of 515K, ST-Link Utility reports correctlyErasing the Flash does not always workSometimes the flash changes its content. Mostly switching between 2 or 3 valuesThank you for your help.

I want to follow the video (https://www.youtube.com/watch?v=Eg_GLvLHM1o&ab_channel=STMicroelectronics) to set up the SWV Viewer, but I am not able to configure the debug configuration, as it is grayed out (like in the picture) and then also the configuration in the SWV Viewers does not appear.I am using the following system: CubeMX v6.6.0CubeIDE v1.10.0STM32Cube FW_G0 v1.5.0Chip STM32G0xxDoes my chip even support this feature or why is it grayed out?

We're working on a projekt with different µC and some so called "Common-Modules".These commons are located side by side our projects and shall simply been linked to these. All this could be done, but on building the project, we noticed, that no modules were built, if the include pathes were relative to the project file. Only if the path is given as an absolute path (for example like "C:\work\thiswork\module1\...") the compilation will be successfull.As the projects will be built local and on a remote server too, absolute paths are no choice for us.Are there any solutions to solve this?Best Regards

I use STM32H753 and USART1 with DMA to receive data of unknown length (Min: 8 bytes Max: 512 bytes) from PC. Data will be sent in burst after every one second. My baud rate is 9600. So approx 1ms per byte.So, maximum, I'm going to get all the data in 512 ms and I'm free to analyze the data for another 488 ms.So, I want some algorithm so that I can parse all data (Min: 8 bytes Max: 512 Bytes) on DMA after all data received.I am using follwoing methods.1) Receiving without DMA and interrupt on every byte.-> Working fine. But the more CPU interference required. 2) Receiving with Half and Full transfer interrupt with DMA.-> Working fine but sometime we need to wait for one second (or more than that, depending upon buffer size) till the filling the buffer (HALF or FULL). It makes the communication process slower.3) Receiving with DMA_CIRCULAR with DMA and keep eye on NDTR of DMA Stream.-> Working fine but sometime we get error because NDTR updates first after receiving data in

I'm trying to use printf with SWV.I'm using a nucleo-wl55jc1 board (stm32wl55). I have soldered SB8 to connect SWO to stlink.I have made all the config but the it doesn't show any trace.this is my setup:Create an empty STM32 project for the NUCLEO-WL55JC1Initialize all peripherals with their default configuration: NoIn CubeMX: Set Debug/Trace: JTAG and Trace: Trace asynchronous swCLK config:debug config:SWV settings:and i click on the red button after thatCODE:override write function:and then printf in main functionAnd ITM_sendchar(*ptr) is being executed, but no printf ouput in console.also i checked with the oscilloscope the signals while debugging : I can see that SWDIO and SWCLK toggle and SWO is at 3.3V

Hello,I would like to disable the LPUART in my project to save power consumption. I am programming a point to point network with LoRa modem. My project is based on the ping pong subghz example.Curently, my board consumes around 107 µA in sleep with the stop mode 2 enabled. I would like to reach a consumption in the range of 1 µA.I think the excessive consumption comes from the LPUART I use to debug. But when I disable the LPUART in CubeMX in the .ioc file and I generate the code, I get compilation errors in stm32_lpm_if.c with vcom_Resume function because usart_if.c does not exist yet.In fact in .ioc file in the subghz phy middleware section, in platform settings tab, the VCOM section is still present with USART Undefined and No solution. So is this middleware configurable without UART ?I am using a custom board with the LoRa E5 STM32WL5EJC module embedded and the STM32WL package.Thanks you in advanceRegardsEDIT : problem solved but I can't delete my post

 The same Part Number: L99DZ100GTR, but one part marking is L99DZ100G while another is L99DZ100G AA. What is the difference between them? Are they both commercial samples?

Hello,I have to transfer the bytes received from UART2 to the circular buffer via DMA. The microcontroller I am using is STM32L010F4  with LL instead of HAL.When I send a sequence of bytes to UART2 I notice that only the first byte is loaded into the buffer and the UART IDLE interrupt is triggered. Every time I send a sequence of bytes the IDLE interrupt is triggered but in the buffer I always see only the first byte.Thanks!#define ARRAY_LEN(x) (sizeof(x) / sizeof((x)[0]))   DMADataCallback _dataCallback; static uint8_t _usartRxDmaBuffer[64]; /* USER CODE END 0 */   /* USART2 init function */   void USART_Init(DMADataCallback callback) { _dataCallback = callback; LL_USART_InitTypeDef USART_InitStruct = {0}; LL_GPIO_InitTypeDef GPIO_InitStruct = {0};   /* Peripheral clock enable for UART and DMA */ LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_USART2); LL_IOP_GRP1_EnableClock(LL_IOP_GRP1_PERIPH_GPIOA); LL_AHB1_GRP1_EnableClock(LL_AHB1_GRP1_PERIPH_DMA1);

I am building ble application on stm32wb and below is the RTC configuration via cubemx.I am trying to implement a scan timeout using the timeserver. Basically, I start a scan procedure and continue scanning until the time-out callback is invoked which terminates the scan procedure. However, for some reason, the timeout callback is never invoked. Below is my API usage./** * @brief callback to timeout if dut wasn't found */ static void scan_timeout_cb(void) { printf("ble: scan timed out\r\n");   // terminate the scan procedure aci_gap_terminate_gap_proc(GAP_GENERAL_DISCOVERY_PROC); }   static struct { uint32_t process_id; uint8_t id; HW_TS_Mode_t mode; HW_TS_pTimerCb_t cb; bool created; } scan_timer = { .process_id = 0, .mode = hw_ts_SingleShot, .cb = scan_timeout_cb, .created = false };   // create a timer if (!scan_timer.created) { HW_TS_ReturnStatus_t tmr_ret = HW_TS_Create(scan_timer.process_id, &scan_timer.id, scan_timer.mode, scan_timer.cb); if (tm

I am interpreting this to mean that each data signal (including CMD line) should all contain equal number of vias. For example if line D0 is routed to MCU and this trace requires 2 vias on its path to the MCU then all other data signals should also contain 2 vias on their path to MCU. Is this the correct interpretation?

I am hoping this has a simple answer. If I develop a solution based on the BLUENRG-355MC and attribute that design is based STMicroelectronics SOC solution, are there additional fees I need to be aware of? I checked the following link:https://www.bluetooth.com/develop-with-bluetooth/qualification-listing/ and saw that this https://www.bluetooth.com/develop-with-bluetooth/qualification-listing/ SOC was qualified with Bluetooth SIG. Would I be subjected to additional fees from Bluetooth SIG?

HiI am running on a STM32G071 board, with my own custom HW (standard 3 phase halfbridge). The control is FOC sensorless with 1 shuntI am having problems tuning the motor, but for starters I would like to run the motor at low speed in open loopI can find a parameter in the IOC file name Open_Loop_FOC which I can set to "true"But how do I set the operating conditions and how do I start the motor in Open loop mode?(I am running MCWB 5.4.1.19309 (I have tried 5.4.4, but it seems to be unstable. STM32CubeIDE 1.4.2 and STM32CubeMX 6.0.1)RegardsKlaus

When the SysTick interrupt fires the debugger quits. I cannot figure out where the NVIC_SetVector statement is for the SysTick. I think it is not set. But I can not find the vector table in the debugger to know for sure. This used to work, But when I updated to the 1.10.1 IDE and 6.6.1-RC2 Build.20220706-1420. It crashes when the systick interrupt happens. I am using the STM32G051K8T

Anyone can explain me where do the following constants come from and what is their function in the RTC? I am starting my own application and I would like to know if these values suit my own application.

What would cause an application to crash the debugger and not be able to reset in the debugger, without exiting the debugger? I am just about finished with my application I have been working on for a few months.The processor is a STM32G051K8T and I have upgraded to STMCubeIDE 1.10.1 and am using the ST-LINK V2 (Blue pill) with my custom board. All of a sudden it is hanging up in the main program.At first it hung up in the middle of a sprintf() statement.The statement was char buf[120]; sprintf(buf,"Calibration Factor: %lu\r\n",ADC1->CALFACT); // dies on this statement print_debug_str("Hello World\r\n"); char buf[120] was originally char buf[40] but I made it longer in the unlikely case it was overrunning the buffer. Made no difference. I changed "ADC1-CALFACT" to "16l" or "(uint32_t) 16" made no difference. it just hung on that command. Since I new sprintf probably used the heap, I went into STM32G051K8TX.ld to maje the minimum heap 0x300 from 0x200. And

If VN7140ASTR-E could be replaced by VN7140ASTR?what is the difference between them?
