Hello @ACohe.3 , I guess the debugger window of the M4 is not updated. You should try to step on your M4 target (if it fails, try to step in assembly (first click on the 'i' icon).

Hello @bipin_g, You should give at least your IRQ handler code if you want to get some answer. As far, you can search for "irq handler gets called continuously" in your browser. I've found the following links which could perhaps help. c - USART1_IRQH...

Hello, First of all, on the STM32H753xI, the RAM ECC can't be turned off. It can't be enabled/disabled like on the STM32H5 or STM32U5. You can refer to Guide: Injecting and Handling ECC Errors in RAM and Flash on STM32H7 - STMicroelectronics Communit...

Hi @theHolgi From which IDE does this screenshot come from? And which version of the tool? On which OS?Which debugger do you use? (I've found a picture of STM32CubeIDE on MacOS with JLink displaying the SFRs in the memory view: from this I would gue...

Hi @theHolgi RAMECC1_M1SR is the status register of RAMECC1 monitor 1 = 0x52009024. This is the AXI SRAM monitor. As RAMECC1_M1FAR (0x52009028) = 0x3ffd, the ECC failure is in AXI SRAM at address: RAM failure address = 0x2400 0000 + 0x3ffd * 8 = 0...
