Could not halt device (19)

[JS8]

Hi,

I am trying to program STM32F030C8T6 with STM32CubeIDE. When I try to upload the code, it says the download was successful but then it fails to halt the device. I have tried setting "Reset behaviour" to "None" as other posts have suggested, but that only results to me getting another error with an unknown reason and it telling me to check power and cabling. I have done so, 5 times already and I have measured every part of the circuit with my multimeter. Everything is connected. What I find weird is that a week ago it was working fine. Only as I expanded the firmware by an order of magnitude, it stopped working.  What could I do to get rid of this error?

Best regards,

Juhani

After this the LED on the ST-LINK/V2 lights up orange, which I know means communication failed.

1. set  "Reset behaviour" to "under reset" or software system reset .

2. is this checked , as in pic.below,  in menu->debug config.->

Hi, 

Reset behaviour is already set to "Connect under reset".

I am not sure what you mean by "this", but all seems to match with my settings in your image.

Thanks for the response.

> what you mean by "this"

= everything , thats checked. :)

ok, so it not stops after download at main ?

You have another F030 to compare ? 

Maybe is damaged, because you wrote: it was working before - before "what" ?

Now try to make a new (empty or small) project and try to debug this, then we see, is chip still ok or not.

I just encountered a similar situation, unable to stop the device (18). You may need to check the code problem. It may be that some IO ports have serious conflicts.

OK OK OK!

I solved this problem!
Shorten the usb length of stlink.
And try connecting directly without using usb hub!
