Solved

I've spend a lot of time on this, and I am out of ideas.I'm a test engineer, and I have a bunch of boards my customer wants programmed.I run the command STM32_Programmer_CLI.exe -c port=swd -w "C:\FW.hex" -v -q but it will fail a lot. I wrote 90% in the title, but it's so odd, because once it works, which may take 10 attempts, it will most likely work again and again if I just keep running that command. I have tried multiple computers, and they all exhibit this behaviour. The customer says they always manage to program the boards with zero issue whatsoever.It used to work just fine, when I programmed dozens of these boards last year. Maybe the programmer is broken. If I could just buy a new V3, I would, but nowhere is in stock. If anybody knows how I can get one, please give me advice. This is my only unit.

STM32F407VGT6Here is my code:#include "main.h"int main(void){RCC->AHB1ENR|=RCC_AHB1ENR_GPIOAEN; while (1) { }}For port A registers (pins 13 and 14) is the configuration done in the IDE? In the code, I did not find the configuration of port A registers, but SWD still works.What settings are needed to install SWD on pins 13 and 14 of port A?I looked at the GPIOA_MODER register, it looks like this: 1010 1000 0000 0000 0000 0000 0000 0000It turns out pins 13 and 14 are set to Alternate function mode.For some reason, pin 15 of port A is also set to Alternate function mode, although pin 15 of port A is a general purpose pin.I cleared those GPIOA->MODER=0; bits, but they are not overwritten when the IDE is restarted.I have to erase the whole chip to get into it.In the code, I did not find where port A is configured, but if the configuration occurs through the IDE, then why are the bits not restored after I erase them GPIOA->MODER=0;------------------------Port A regist

Problem: I am trying to create a bootloader and a user application to do my Over the air project. So for custom bootloader I had selected sector 0 and sector 1 of flash memory. (Address starts at 0x08000000) and from sector 2 I want my user application. So I created both of them and when flashing bootloader I don't have any problem with cubeIDE. Now when I flash application on sector 2, the earlier bootloader section 0 is getting erased. How can I prevent from happening in cubeIDE. If I use cube programmer I have control over the options, but how can I do that with STM32 Cube Ide?-------------------------------------------------------------------------------------------------------------------------------Details:I use STM32CubeIDEVersion: 1.6.0Build: 9614_20210223_1703 (UTC)Hardware: Nucleo-F411re

I am working on a USB device based on a STM32H743 MCU, using ThreadX/AZURE and USBX.According to RM0433 (the reference manual for STM32H742, STM32H743/753 and STM32H750), the USB peripheral supports:- bidirectional endpoint 0- 8 IN endpoints- 8 OUT endpointsHowever, _ux_dcd_stm32_endpoint_create() reports a UX_NO_ED_AVAILABLE failure whenever I try to use any matching IN and OUT endpoint, for example IN8 and OUT8. Am I missing anything? Is it a bug? Is there a workaround?Thanks!Bart

I'm using a stm32f469-disco in a project that require CAN bus connectivity, but after the CAN configuration from the file .ioc the hal_can source file is not imported, so i can't even build the project (error with HAL_CAN_Init).

STM32F407VGT6Why is access to the Microcontroller broken after this code?The MODER register after this code should look like this: 00000000000000000000000000000011this is Analog mode for pin 0 of port A.int main(void){RCC->AHB1ENR|=RCC_AHB1ENR_GPIOAEN;GPIOA->MODER=0x3; while (1) { }} Same but with port B or C does not throw an errorRCC->AHB1ENR|=RCC_AHB1ENR_GPIOBEN;GPIOB->MODER=0x3;-----------------------------RCC->AHB1ENR|=RCC_AHB1ENR_GPIOCEN;GPIOC->MODER=0x3; ----------------------------Port A is compatible with Analog modeA user button is connected to pin 0 of Port A, but it is not pressed, which means it does not interfere with the execution of the code.

I am using the SBSFU project for OTA.I have linked my UserApp successfully with SBSFU projects and firmware up-gradation is working fine when FIREWALL protection is disabled.I am using the STM32L4 series controller and am aware of L4 series firewall-related issues.So I want to know how I can use firewall protection only for Flash by disabling firewall protection for SRAM1.The datasheet mentioned that if we pass length 0 of Volatile data segment (SRAM1) and VDS = 1 then protection is disabled for SRAM1 but I am still getting firewall reset.How can I bypass SRAM1 firewall protection?

Studying the example application in the STSW-IMG 023 software I noticed that in the main.c file in the static void MX_I2C1_Init (void) function a clock speed equal to 1000000 (10 ^ 6) is configured, but if I go to the CubeMX file from where the project was generated I read 100000 kbit / s instead (10^5). Is it correct?  If in the main.c file I wrote 10^5 instead of 10^6, the application does not work correctly. Only 10^6 work correctly. Can you help me understand why? Moreover, in the comment on the field init.ClockSpeed I read "This parameter must be set to a value lower than 400kHz"I was using version 1.3.0, but this fact is also present in 1.3.1

Lets start with what works... I can write NDEF payload to ST25DV via I2C and read it back via I2C and using NFC Tools App.... This works fine and perfectly. I can also write NDEF messages using NFC Tools, and read back what I wrote no problem. The exact issue comes up when I try to read what I wrote to the ST25DV tag (using NFC Tools) using NFC. I don't get garbage exactly... i do get some correct bytes out (the NDEF header is mostly correct), but the payload data portion seems corrupted. What i get from reading via I2C is repeatable...as in I read the same corrupted data with every read. If I write a new NDEF message via I2C, then the corruption no longer exists and I can read back the NDEF message that I wrote (via I2C) without issue. NFC Tools App allows you to read the memory from the ST25DV. The memory I am reading doesn't match what I read via I2C after I write to the ST25DV using the NFC Tools App. The NFC Tools App seems to have access to a different memory then what the I2C do

Even though it is not really advertised as having changed a lot, it looks like the U5 increased the throughput of the PKA unit nearly 3 fold (upper L5, lower U5):Is this really the case or did the way of obtaining those numbers change in between (e.g. by using different curves)?I was very surprised when I saw those numbers because the marketing/summary material only mentioned hardening, not performance increase.

Hello,I would like to measure the period of a square wave (around 1 kHz) with a timer in input capture configuration. I am using TIM5_CH3 on pin PA2 (nucleo G474RE).I would like to receive a bit of help in debugging my code since i am not able to measure the period of an external waveform (also tracked on my oscilloscopes). void TIM5_Init_ToMeasurePeriod (void){ // Enable the GPIOA Clock RCC-> AHB2ENR |= (1<<0); // Enable the GPIOA clock writing 1 in bit 0 // Configure the GPIO GPIOA -> MODER |= (1<<5); // Port PA2 configured as alternate function GPIOA -> AFR[0] |= (1<<9); // Set alternate Function 2 i.e. TIM5_CH3 for PA2 // Enable the timer clock RCC->APB1ENR1 |= (1<<3); // Enable the tim5 clock writing 1 in bit 3 // Set the timer timebase TIM5 -> PSC = 1; // 80 MHz/2= 40MHz clock --> 0.025 us count set the resolution (1ms=40000 counts) TIM5-> ARR = 0xFFFF; TIM5 -> CCMR2 |= (1<<0); // CC3 channel configu

Hi, I am a newbie in stm32. I am trying to receive DMA from USART1,USART2,USART3.But I am confused as how to do it because, all of them go inside same routine of DMA. Therefore how do I distinguish between different usart. my controller is stm32f103c8

Is there a way to programmatically exit from mute mode ? It seems that MMRQ can only be written to '1' to put USART in mute mode, but there isn't the possibility to return to a 'normal' behaviour by software. Any info to share ? Thanks

hello stI am using ST25RU3993-HPEV now, now I want to use UART to communicate with the host, please tell me the detailed operation steps, thank you!Second, if I want to reduce the communication rate (3M), such as using 115200, what should I do?

I need to write the HEX file, but the new IDE 1.9.0 won't let me select the HEX file.How can I edit this configuration without help from the IDE?Where is this configuration stored? The old project did not have this problem.The HEX file is generated after compilation to add the CRC value, so I need the IDE to allow the HEX file as well.     Reference on generating the file with CRC:https://community.st.com/s/question/0D50X0000CAsLXASQ3/how-to-use-halcrcaccumulate-bufferlength-does-not-accept-the-entire-flash-volumehttps://github.com/ethanhuanginst/STM32CubeIDE-Workshop-2019/issues/4

Hi,I'm trying to read data from the SPDIF-input of the STM32F466 using the CubeMX-generated code. The idea is to get one interrupt/callback for every pair of audio samples which arrive. This looks good so far, there is a function HAL_SPDIFRX_RxCpltCallback() which has o be overwritten in own code section.Now the question is: when this callback is called, how can I get the related data? Is there an other function to get these data or do I have to read some registers directly?Or more generic: is there a manual available that describes these CubeMX-generated functions?Thanks!

Hello, First time using the forum so apologies if I mess something up...Long story short I wanna get a microsecond delay, I know 2 ways of doing it:1) I can start a timer with default cube values and use a function like:void delay (uint16_t delay) { __HAL_TIM_SET_COUNTER(&htim1, 0); while( __HAL_TIM_GET_COUNTER(&htim1) < delay); } to get the desired delay, or2) I can start timer, set its prescaler value to specific frequency with interrupt turned on, drop it down to 1khz/mhz for easier calculations and in timer callback function have some variable increase by 1, then use it in different function as time measurement, something similar to this:uint8_t counter;   void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim){ counter++; }   void main() { while(){ if(counter==20){ // do smth counter=0; } } }I have used both of these methods previously and know one is running in blocking mode, other in non-blocking mode. So that got me wondering, what other differ

I'm trying to run/debug my code on a Nucleo with STM32F466 via the SWD interface using a J-Link debugger. Unfortunately this always ends up with a messageCould not connect to target.Please check power, connection and settings.Trying to connect to the debugger/the board using an other IDE brings up some more information: here I'm getting an error message of the target having no power.Now when I measure the SWD-interface (CN4), I find the error message is correct: there is no power at the CN4-pins 1 (VDD) and 3 (GND). So what is missing here? Do I need to set one of the jumpers to get the SWD interface powered properly?As described in the manual, the two jumpers at CNs have been removed, the Nucelo-board itself is powered via USB.

I have the following configuration, but although I include the ones that I consider correct, I still get many errorsThe errors are supposed to be related to the tcp-ip component, but I already included it and I don't understand what is wrong, maybe I am missing another configuration besides paths. I have the development board SPC58EC-DISPThank you.
