Hi We want to use STM32U575 Watchdog Mechanism in our operational FW, but have the following concerns:1. Can MCU ST Bootloader kick the WD in general, and especially duringca FW update, when it is busy writing/reading to flash the new FW to update or...

In an earlier project based on STM32F7x, we had to add memory remapping by hand:SYSCFG->MEMRMP = 0x01;There is no equivalent in SYSCFG for STMU575, nor did I find relevant bits under SYSCFG->CFGR1 or CFGR1->CFGR2 or other field as part of SYSCFG.

Thanks for elaborating.Ok, that seems like an optional solution, though it will add have complexity impact on the FW update procedure, and the flag will need to mark both the need for not activating the WD and the need for a FW update:Build the FW pr...

Thanks for a prompt answer.I'm not sure I've understood your suggestion. After its initialization is done, our FW requires that the WD would be activated, during its execution, to catch malfunctioning.It can receive a request in CAN from the host to ...

Thanks for a detailed answer.There are three items I want to further clarify Item 1:Q1. Can MCU ST Bootloader kick the WD in general, and especially during a FW update, when it is busy writing/reading to flash the new FW to update or during its execu...

Hi Diane POMABIA Can you please see the following order of operations:A. I notice that the option bytes are not changed after restart (I observe this using theSTM32CubeProgrammer' reading the nSWBOOT0, nBOOT0), if in the jump to bootloader function, ...

Hi Diane POMABIA In the example you have attached, I see code pretty much similar to the code we use on our target STM32U575 (and not in the host). Can you tell which host do you use to run this code, which is connected via FDCAN to STM32? I find the...

STM32U575 Watchdog Mechanism - ST bootloader, debugging & logging WD resets events

Does HAL_NVIC_SystemReset activation required disable interrupts before calling it (STM32U575)? I call it in order to reset the MCU, upon a command request from a host connected to it.

STM32U575 is memory remapping required - prior to jump to bootloader from application?
