ADC making code not upload correctly

[JS8]

Hi, 

I'm programming an STM32F030C8T6 MCU. When I attempt to upload my code, it gives me an error: "Could not halt device (19)". I noticed that this only happens when ADC is enabled from CubeMX. When I disable it, everything works fine. The code doesn't even use it. It is only when I have enabled ADC in the .ioc file in my project directory in STM32CubeIDE. I need ADC for my project. What could be causing this and how can I fix it?

Thanks.

Did you try to up- or down- grade the software pack:

->

 

 

(in IDE, in edit ioc -> CubeMX-> manage software packs ...) then you see this;

Hi, 

I removed the most recent install and installed the previous software pack. Didn't work, sadly.

Hello @JS8 

Is there any warning in CubeMx when you enable the ADC?

[JS8]

Hi,

I don't see any warnings. Where would these typically appear?

Hello @JS8 ,

Could you please send your project including your .ioc file?

Is this a custom board? Perhaps an error in the design/schematic. How is VDDA connected? Can you provide the schematic?

Hi,

I noticed now that VDDA is connected to VDD in my schematic, but I had not connected it in the PCB design. This is definitely the cause of the problem. How could I resolve it without ordering another one? Also the pins are so small that I doubt I will have any luck soldering them together.

Thanks.

Depending on the layout, you can solder multiple pins together to make the connection. For example, solder all of VDDA, PA0, PA1 in a solder bridge to make the VDDA pin effectively bigger, then bridge it with a wire to VDD. Going to be challenging with hobby soldering tools, but possibly doable.

But yeah, that's your problem VDDA being left unconnected is the issue causing the error you're seeing.

Design software should have checks to ensure this doesn't happen, but you do need to remember to run them. We all make mistakes, good luck.
