STM32G474 error code

[Stone1]

Hi, 

I'm using STM32G474RET6 for development.

When I debug code by SWD, the download verified successfully.

But it will be suspended at HAL_Init() and show an error is Break at address "0x1fff5048" with no debug information available, or outside of program code.

Is there something I need to notice?

Thanks.

Hello @Stone1 and welcome to the Community :) 

Check state of BOOT0 pin, and option bits.

Check also your clock settings.

Please share more details (ioc file, code, clock settings, schematics...) if your issue is not resolved. This will help to better understand your usecase.

Hi Imen,

BOOT0 pin now is floating. Should I tied to GND?

I have two same board. The first one can normally work. But the other one met the issue as I mentioned.

Hello @Imen.D ,

The previous issue is solved. But for a while there is another issue.

The issue are are the following. 

I check the BOOT0 pin, and option bits. 

BOOT0 pin now is connected to GND.  I use STM32 ST-LINK Utility to read option bytes as following picture.

I can boot it and debug it at the first time, but for a while I can't. Is there any setting that I didn't notice it?

Thank you.

Is this a custom board?

Make sure BOOT0 is pulled LOW and not floating.

HI Tesla,

Yes, I already pulled low the BOOT0.

Make sure you don't have any code re-configuring GPIOA PA13 / PA14, or going into a low power mode that might cause the debugger to disconnect

Sorry, when I pulled up the post I didn't see the earlier responses..

Hi Tesla,

I don't change PA13 and PA14. Could you tell me how to set low power mode?

I'm not sure I'm in lower power mode or not.

I find it sometimes it can connect and will disconnect suddenly.

Thanks.
