HiI use cubeide and baremetal to program itit worked fine for a couples of daysthen all of the sudden im not able to debug it, I can download to it but as soon as I execute the first like (step code) it gets to the NMI interrupt where the code is whi...
Is it possible to update executable code without reflashing the entire device, and without overwriting the entire codebase?Ie,multiple applications, such that individual applications can be separately installed, updated, and uninstalled?We don’t want...
I have a program that writes to flash using HAL_FLASH_Program().Before it does, I erase the flash with this function:bool Erase_Flash(void) { static FLASH_EraseInitTypeDef EraseInitStruct; uint32_t PAGEError = 0; HAL_StatusTypeDef status; print...
Hi.I'm trying to implement a SPI slave device using a STM32F401 with DMA. I'm being able to do Rx without problems but once I do a Tx everything goes crazy: first the next receive operation reads the last transmitted byte and after that any transmit ...
I am using STM32L4S9AII6 MCU.I am exploring options to ensure that certain outputs are forced to a known safe state during power up. I want to be able to take advantage of the MCU's built in GPO pull-up and pull-down configuration features, but I am ...
Hello all.We have developed in the past some devices using the STM32F4 and F7 families, with no issues using ADC+DMA+Timer Triggering with no effort (mostly tweaking the examples provided by ST and using the ioc Cube files).However, we are trying to ...
I am trying to use bitmapped structures to send data to an i2c DAC. I defined the fields as:typedef enum { mcp4726_command_code_write_volatile_dac_register = 0b000, mcp4726_command_code_write_volatile_memory = 0b010, mcp4726_command_code_...
Hello allI have a custom STM32L496RGT3 based board which I've configure to run at 64MHz off the HSI using CubeIDE:void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Conf...
Hi!I use SRAM 1 (0x30000000 - 0x30003FFF) in D2 domain for USART2, USART3 DMA buffers. All work clean. If I use SRAM2 (0x30004000 - 0x30007FFF) just after running debug it's all right. But after "Reset chip and restart debug session" the first access...
CPU hangs when calling I2C_WaitOnFlagUntilTimeout because I2C DMA interrupt handler has higher priority than system handle, so that tickcount cannot hit the Timeout. How can I resolve this trouble without consuming too much CPU ? I saw some topics ab...
