I have used CubeMX to generate an application structure for the STM32F746 DISCO board.When trying to run the most basic application, during the initialisation, TIM6 is set to be the HAL tick source, when it is enabled, it immediately jumps to its int...

Basic project with the defaults from the config wizard for STM32L4S7Add into the main while loop: declared_volatile_variable += 1; HAL_Delay(1000);Set a break point on the addition and debug. Every second, the breakpoint triggers, then continue...

Hello,STM32Cube FW_L4 V1.17.0When changing the timebase of the systick, the HAL_Init() function no longer returns and it goes off to system memory in a loop.To replicate, start a new project with for the NUCLEO-L4R5ZI, initialise all pins to the defa...

I have not found the cause of it yet, it keeps coming back from time to time.I have made some changes to the MPU config, which makes it go away temporarily.We recently noticed that we were clocking the RAM at 120MHz, which is out of spec. Lowering th...

Hello,In the units MPU config, there was a section that was:MPU_InitStruct.DisableExec = MPU_INSTRUCTION_ACCESS_ENABLE;and changing it to:MPU_InitStruct.DisableExec = MPU_INSTRUCTION_ACCESS_DISABLE;This then stopped the issue.This does not seem like ...

The fact that I can change 1 bit in the program and the behaviour goes away, I think, suggests that it is not an obvious hardware problem like an address bit being stuck. I can read and write to both locations in the fixed version so the functionalit...

I have found a very similar problem to this, but the duplication was once, 1MB up the SRAM. Stepping through the disassembly, I would see it doing a store to an address 0xC0035B10, but that value would also "get written" to 0xC0135B10.I am still debu...

Hi. Thanks. Should this information not be included in the chip's errata document?

F746 Disco - Why does TIM6 trigger and stop application running in init

Why does changing the floating-point ABI from hard to soft, stop HAL_Delay returning?

NUCLEO-L4R5ZI Changing timebase source fails

STM32L4R5 Nucleo FreeRTOS Broken
