CubeMX 5.0.1 LL driver warning

This warning present since I started to using low layer driver, it was around 2 -3 months before.

Got this with previous in CubeMX 4 as target dependent migrating from L496 to L4R

It seems not related to CubeMX version.

Thanks for confirming, but that's nevermind. It's still a bug which needs to be fixed.

Hi,

I am having this exact same issue.

Can ST comment on when this will be fixed?

Thanks.

[kurta999]

Any news please?

Tested with STM32CubeMX 5.1.0, everything is the same as before.

Do you use IAR? I've recently had similar warnings, and the problem was because 'Defined symbols' in the project options generated by CubeMX conflicted with the ones in *.h file.

[kurta999]

I'm using Atollic TrueStudio

Fixed in L4 LL 1.14.0

[R Piacenzia]

Hi.

I'm using CubeMX 5.21 and latest L4 firmware V.14.0.

Keil MDK shows it is using L4 DFP 2.20 and LL driver versions 1.9.

How do I get the L4 LL 1.14.0 you reference?

Or with Keil do I need to wait for ST's next DFP release to have the fix?

Thanks.

[kurta999]

I don't have any experience with Keil MDK, so I can't help with that.

But you can get the latest L4 package here ( https://www.st.com/en/embedded-software/stm32cubel4.html ) or via latest CubeMX.
