STM32CubeMX5.1.0 ADC "DMA Continuous Requests" doesn't work

I opened an older project which was created with 5.0.1, and the newest CubeMX shows an error for this option in ADC. But this option is correct. I tried to create a new project, and I wasn't able to enable this option here.

Hi!

I have the same issue here. It's a new issue for the STM32F446RE board.

Hi,

I too am having the same issue. There is a red "x" for "DMA Continuous Requests", and hovering over it, the message is "DMA Continuous Requests parameter can only be set to enable if a DMA request is active in the DMA settings tab". Of course, I do have a DMA request set up.

Let me know if you need more information on this little annoying HAL bugster.

I struggled with this issue for longer than I would like to admit. I was uninstalling and reinstalling different versions of CubeMX to no avail.

To my surprise, I found that if I created a new project, I was able to configure "DMA Continuous Requests" as enabled, but using my existing project, I was not. I did a diff between the two ioc files, and performed the tedious process of changing things one by one until the "Enable" option appeared.

The magic setting was the CubeMX Database version.

My faulty version was "MxDb.Version=DB.4.0.270".

My correct version was "MxDb.Version=DB.5.0.10".

I don't think users should be required to change low level files to configure critical settings like this. If it exists through the GUI, I've never seen it in obvious places (project manager, etc).

Turns out "5.0.10" isn't the correct version, as you cannot use RefInt, Temp or VBat!

You need to use "MxDb.Version=DB.5.0.0".

What a nightmare!

ST Tech Support says: "...the temperature sensor doesn't allow you to do dma continuous request...it's bug of CubeMx."

Hopefully they will fix this annoying....bug. Soon.

​Hello @Rogers.Gary​ 

This issue has been fixed in 5.2.0 CubeMX version.

Best Regards,

I can confirm that with new blank projects, and version 5.2.0, which uses MxDb.Version=DB.5.0.20, the issue is fixed.

However, 5.2.0 cannot seem to open my file (CubeMX spins forever on trying to load it). It was able to be opened with 5.1.0.

See attached.

So it means, this issue is fixed too? It's mainly related to low layer driver, with HAL it worked before.

Yes, this is fixed. I can confirm it too!

But you can't measure temp sensor with vref with LL, because freshly generated code will only enable measuring vrefint. Tested with 5.2.0.
