Resolved! STM32F30f4, standard cube configured out of the box software locks up after fixed number of processor cycles. IO looks to resets also. Loops in system memory starting at 0x1ffffed68. Only if sysTick is enabled. Does not get to sysTick interrupt.

STM32F30f4 Does this in debug mode or release with and without STLINK attached via SWCLK Pin 20,SWDIO Pin 19,NRST Pin 4.Using HSI clock and PLL , but tried also without PLL. I've only enabled IO on the standard IO lines available, PA0 -> PA7 Pin 6 to...

Why do I get hardfault before reaching main in app running on external flash ?

Hello,I have one custom board using STM32H750 MCU. Everything was working perfectly until while doing some testing my code is not launch anymore. This is the second board that was working and stop working for "no" reason. On the first board, after an...

Resolved! STM32H743 BDMA channel for SAI4 not described in Manual

I am trying to program BDMA of STM32H743 using Nucleo board to perform DMA Peripheral to Memory operation . What I have found a bit difficult is that I could not see any information on Reference Manual , Datasheet or on forum for the mapping informa...

Resolved! STM32F407 DISCOVERY board CAN example

I have tried to get the CAN peripheral up and running on STM32F407 discovery board.But I am stuck at one point. Inside method HAL_CAN_Init(CAN_HandleTypeDef *hcan), I end up in the HAL_CAN_STATE_ERROR.Is there any example available to test on the dis...

Hello,I need to know the FIT value of STM32F7 Series (STM32F746VGT,etc) to compute the reliability data.Could anyone tell me that information ?Thank you in advance.Toshiya

STM32G070 FLASH status register (FLASH_SR) Address offset: 0x010 Reset value: 0x000X 0000 How to reset flags CFGBSY(18) and BSY1(16) if they are set at startup? All further operations with flash are impossible.

using 32 MHz crystall with STM32L011K4

Hi,In a project I need a precise timing so I cant rely on th internal oscilator and want to use a crystal 24-32MHz with MCU. But actually I couldnt find anything about this possibility in datasheet.the sample is 32 KHz that is not good for my applica...

STM32F779BIT6 custom board SD card initialization failed.

I am using custom board with STM32F779BIT6, connected micro sd card to the controller.Every time I initialize micro SD card gives error of SDMMC_ERROR_CMD_RSP_TIMEOUT.Any solution.

Why Linker file needs to be modified to use External memory(RAM/Flash) if I can access external memory using communication modes like SPI,I2C,etc ?

I have seen many examples to use external memory as heap but for it they have modified the linker and added section of needed memory. But I am curious if I can access the external memory using standard communication interfaces like I2c, SPI, etc then...
