How to reboot a device using CubeProgrammer_API.dll and USB Bootloader interface ?

[Sofiane]

Hi,

I probably didn't search correctly in the documentation, but i didn't find a command to reboot the device using the USB Bootloader interface . I found a reset method but its with STLINK and its not what i'm using.

Is there any method available ?

thank you for all the help you can provide

Hello @Sofiane,

"I found a reset method but its with STLINK and its not what i'm using."

referring to the STM32CubeProgrammer  User manual Figure 112. STM32CubeProgrammer: available commands

You can add the option  -rst in the command which is not specific to JTAG/SWD debug port as show in the screenshot bellow .

please let me know if this solved your issue .

Hello @STea ,

thank you for your answer.

unfortunatly, i'm not using the command line tool provided by STM . i'm using the CubeProgrammer_API.dll in one of my C++ project. and when i try to call reset(SOFTWARE_RESET) or reset(HARDWARE_RESET) , i get and exception : Access violation reading location 0x00000000000000F0. 

So i'm guessing that the command cannot be called from my program as i'm doing it. 

what would be the corresponding C++ call for this --rst option command when you are using the USB interface to deal with a device ?

Again thank you for your help

Hello @Sofiane,

The function call corresponding to the "-rst" command is "reset(SOFTWARE_RESET)". However, as you said, this function is only available for the JTAG/SWD debug interface and cannot be used with the bootloader interfaces.

As a result, resetting the device through the USB bootloader interface is not possible with STM32CubeProgrammer APIs.

Hi @Maryem ,

So i will find another way around for this matter then.

If you can push in code into RAM, and jump to it, you could use NVIC_SystemReset() or equivalent. Or watchdog
