Hello!I have these code to store/read data in the EEPROM of my STM32L031K6..The write function works, the data is saved in flash correctly...When i want to read the data back, i falling in the HardFault Handler.... :\This is my Code: eeprom.h#define EEPROM_BASE_ADDRESS 0x08080000UL   HAL_StatusTypeDef writeEEPROMByte(uint32_t address, uint8_t data) { HAL_StatusTypeDef status; uint32_t eepromAddress = address + EEPROM_BASE_ADDRESS; HAL_FLASHEx_DATAEEPROM_Unlock(); status = HAL_FLASHEx_DATAEEPROM_Program(TYPEPROGRAMDATA_BYTE, eepromAddress, data); HAL_FLASHEx_DATAEEPROM_Lock();   return status; }   uint8_t readEEPROMByte(uint32_t address) { uint8_t data = 0; uint32_t eepromAddress = address + EEPROM_BASE_ADDRESS; data = *(__IO uint32_t *)eepromAddress; return data; }i think, the convertion from uint32_t to uint8_t is wrong, but it works to write the data...

Hello, in my project I'd like to use printf for print debug messages, but if write printf("Test"), I don't see the string on the UART.I have redirect printf:#ifdef __GNUC__ /* With GCC, small printf (option LD Linker->Libraries->Small printf  set to 'Yes') calls __io_putchar() */ int __io_putchar(int ch)#else int fputc(int ch, FILE *f)#endif /* __GNUC__ */{  UartWrite( UART1, (uint8_t*)&ch, 1, 0 );  return ch;}The code no entry in the function fputc, why ?Best regardsLuca

Hello!I am new in STM32, forgot my stupid question...How can i store a variable in EEPROM or flash?I have a STM32L031K6 Nucleo board, and got my CC1101-868MHZ transceiver with interrupts to work.I receive a unique address over RF, and want to store this client address, now i can't find any examples for storing...is there any examples to store variables in EEPROM or flash?Thanks guys!

In the X-CUBE-EEPROM library (https://www.st.com/en/embedded-software/x-cube-eeprom.html)FLASH_OPTR_BFB2 is defined for the stm32g474 inDrivers/CMSIS/Device/ST/STM32G4xx/Include/stm32g474xx.hand therefore the following in Middlewares/ST/EEPROM_Emul/Porting/STM32G4/flash_interface.c is also defined.```uint32_t bank = FLASH_BANK_1, page_error = 0U;#if defined(FLASH_OPTR_BFB2)  bank = GetBankNumber(PAGE_ADDRESS(Page));#endif```however, GetBankNumber() is only defined in the L4 and L5 flash_interface.c files. It does not have a function definition in the .../STM32G4/flash_interface.cThis seems like a bug in X-CUBE-EEPROM. Is there a way to report this bug directly? or anyone know of a fix for it? just commenting out "bank = Get..." gets it to compile, though I have not tested if this actually works yet.

Hi,I am using STM32L476RG MCU and trying to store some values in the EEPROM. When I try to program a 64 bit data, FLASH_Program_DoubleWord(Address, Data) is called and it is failing to program the data. FLASH->SR is set to 160 which I assume Fast programming data miss error. Could anyone tell me what is the problem?the 64 bit data is 0xa1c50001 and the address is 0x8080020.Thanks,Ankush

MPU6050 is I2C device which has an output of accelerometer and magnetometer and I need to filter it.

Powered the development kit via micro USB.Running a simple LED toggle program.Using IAR 8.5 the code runs and I see LED getting toggled.If I generate hex and flash it via JLINK , I dont see the LED toggling.Tried repowering, pressing reset button.. It doesn't help. IAR optimization level is None.

i tried to debug the code but i am getting error while loading the code.Please help me.

so the problem is, Some time Atollic studio is giving the error while dumping the code in Debug mode. But if I try on Nucleo it is working fine.Thanks In Advance

Hi,I am trying to adapt CubeMX code for a single ADC with DMA readout. I and using a Nucleo-G431KB board and managed to port a single conversion without problems. The code compiles OK and looks like many examples on the web. However it throws an error when HALADC_DMA_Start is called. It does not perform conversions and it seems the callbacks never called. Any help is welcome.  /* Analog input, serial output   Reads an analog input pin. Also prints the results to the Serial Monitor. */   #include "stm32g4xx_hal.h"   const int analogInPin = A0; // Analog input pin that the potentiometer is attached to #define ADC_BUF_LEN 32 #define LED_PIN 13   ADC_HandleTypeDef hadc1; DMA_HandleTypeDef hdma_adc1;   // Variables int a = 1; uint16_t adc_buf[ADC_BUF_LEN];     void setup() { // initialize serial communications at 9600 bps: Serial.begin(9600); /* Initialize all configured peripherals */ //void SystemClock_Config(void); MX_DMA_Init(); MX_ADC1_Ini

Hello,I am using STM32F469NIH with ST-LInk and Keil uVisiom debugger. When try to debug it gets the error popup to the effect that ROM Table not found. This ST-Link and the debugger works on other STM32F469NIH board.What could be the issue.It is very critical.Regards,Kanak Nath

In my code for Arduino101, I use the following:#include "CurieTimerOne.h"This is the point where I get an error when I use Nucleo64 STM32L476. I have no problem when I use Arduino101. However, a problem arises with Nucleo where it cannot find this library.The error message while using Nucleo is:MyFileName:50:10: fatal error: CurieTimerOne.h: No such file or directory  50 | #include "CurieTimerOne.h"   |     ^~~~~~~~~~~~~~~~~compilation terminated.I downloaded this library from Github and added it to the existing libraries' folder but no success!Whatever I do with the sub folders included in this library and other dependencies, I cannot fix this problem.Any help is appreciated.

I'd like to be able to printf into IDE console during debug. I'm using Atollic 9.1, Nucleus F413 board with Segger debug programmed into onboard debug interface. I followed the instructions here:http://blog.atollic.com/cortex-m-debugging-printf-redirection-to-a-debugger-console-using-swv/itm-part-1Nothing happens when I printf: The debugger never hits a breakpoint in the modified _write in syscalls.What am I doing wrong?Thanks!Best Regards, Dave

Hello,I have settings in my EEPROM. I would like to assign these parameters with a #define.I tried several things, searched the internet, but couldn't find anything conclusive.I found something, but it is not suitable for my program, here it is :#define a ((uint16_t*) ((uint32_t) 0x08080000))It works this way :if(*a == 1) { ..... }But it doesn't work that way which fits my program :#if( *a == 1) ..... #endifDo you know the right way to do it ? Thank you

I made a Nucleo L476RG myself. However it seems it cannot run Mbed codes.How do I enable Mbed on the board?

Hi Community,I am using the EEPROM emulation library from ST (X-CUBE-EEPROM_V2.0.0) in a project with the STM32G070, and I am trying to understand why should I use EE_FORCED_ERASE in EE_Init functionI found this in the documentation (AN4894) :EE_InitConfigures the EEPROM emulation variables to their initial state and restoresthe Flash pages to a known good state in case of asynchronous reset orpower loss during Flash write or erase operation.Erases the Flash pages that need to be erased (for instance pages not fullyerased in ERASE state, pages in ERASING state). The EE_FORCE_ERASEparameter has to be used by default. If the application guarantees that noasynchronous reset nor power loss can happen during Flash write or eraseoperations, then the EE_CONDITIONAL_ERASE parameter can be used; referto Section 4.6.2: Page header recovery.After reset, this function should be systematically called prior to accessing theemulated EEPROM.4.6.2 Page header recovery.... In order to avoid a possible f

I created a minimal custom Nucleo L476RG board. There is no 8 MHz crystal on the board and only a 32.768 KHz crystal. I connected an LED to PA_5 pin and trying to test the Mbed blinky program. I upload codes to the custom board via SWD connection from another Nucleo STLink. I am powering the board of 3.3V DC power supply.The problem is the timing in blink. While i set it to 1 sec, the LED does blink on and off for one second but in between, sometimes, it blinks 5 times a second. Same thing happens if I set timing to some other time. The LED randomly blinks 5-6 times a second now and then after blinking for set time properly for 2-3 seconds. This happens regardless of the SWD connectors disconnected or connected.Very very weird: THE PROBLEM DOES NOT OCCUR FOR ARDUINO COMPILATION OF THE EXACT SAME PROGRAM.Mbed code:#include "mbed.h"DigitalOut ledpin(PA_5);int main(){     ledpin = 1;  while(1){    ledpin = !ledpin;   &n

Hello there. I want to do static code analysis with cppcheck. I did my project with Iar Embedded Workbench. How do I enable it on IAR.

I have removed STLINK jumper from JP2.I have connected I-Jet to MIPI10.On I-Jet, I see USB and TPWR LEDs are green, and DBG LED is off.When downloading code get error: CPU did not power up.None of the Nucleo's LEDs are on. Seems like there is no power to the CPU? I thought the power came from the I-Jet?

Hello,I am trying to program and debug only the M4 core of the STM32H745 processor using MDK-ARM v5.16a. I understand that dual core debug support was added in MDK-ARM v5.25, but I don't see why I can't treat each core separately for now. A few details:MDK-ARM v5.16aBoard: NUCLEO-H745ZI-QST-Link V2 Debug Probe (External since MDK-ARM doesn't support V3)Software Example: STM32Cube_FW_H7_V1.6.0\Projects\NUCLEO-H745ZI-Q\Examples\WWDG\WWDG_ExampleNote that with MDK-ARM (Keil uVision) 5.16, I cannot see or select the STM32H7xx_CM4.FLM or STM32H7xx_CM7.FLM flash loaders. The only flash loader I can select is STM32H7x_2048.FLM. When I try to flash the M4 variant of the above example I am presented with the following in Keil uVision:Load "STM32H745ZI_Nucleo_CM4\\Exe\\STM32H745ZI_Nucleo_CM4.axf"Cannot Write to RAM for Flash Algorithms !Erase Failed!Error: Flash Download failed - "Cortex-M4"Flash Load finished at 16:34:26I have tried updating all my flash and memory addresses to match

Im using stm32f429i-disco and TrueStudio v9.2.0 , i have a program to write and read to FLASH, when i start to debug at first attempt it works fine but on second attempt it throws an error :Failure at line :6 in 'Target Software Startup Script'. Please edit debug configuration settings.Error finishing Flash operation.Why this error is coming up even when my Flash write and read are not continuous but only time operations. Every time i have to erase the FLASH chip from ST-LINK Utility separately.I have attached the snapshot of error :
