Hi,

When using the .ioc to generate the code, it always shows:

- SMPS must be enabled to reach the best consumption figure. SMPS can be enabled from the Pinout tab under PWR

How to get rid of this? Or just omit it?

Hello @diverger

Is just a message that contain some tips that may help the user to reduce consumption or in other cases to make the code work more Fluently or.... If you are not using them, you just have to omit them. But you can't disable them. If you find this helpful, I've escalated your request (in the internal ticket number 187848) to the Cube team so they may consider this recommendation to disable/enable those pop-ups in the coming releases.

Best Regards.

Hi STTwo-32,

I'm using CubeMX 6.10.0 and try to configure STM32U575.

I keep getting this message and don't see any option to enable SMPS under PWR

@Texram , there are two bugs here:

1. ~~Cube gives you the warning about enabling the SMPS even for STM32U5 parts which do not contain an SMPS.~~

(can't reproduce this now, I must have confused projects with diff part numbers when checking this)

2. If the part does include an SMPS (part number includes a Q suffix), the UI buries the SMPS enable option 5 levels down:

Now that's some mighty terrible UX right there.

I've started this bug-report thread

@Texram , could you tell me which specific U575 you're working with and what CubeIDE version you're using? I thought I saw (bug 1) above, but I can't reproduce it now that ST has asked me to. Does your project use a xxxQ (i.e. with SMPS) part number?

Hello @BarryWhit ,

Further to your comment, the SMPS is well removed from configuration of Power Saving Mode.

[ STM32U595xxxx] ; [STM32CubeMX 6.12.0]

We still have a waring Mentioned above.

In fact, this problem has already been reported internally to the development team through ticket 166502.

Thanks.

@Mahmoud Ben Romdhane , I'm not sure I understand you. What exactly do you mean by "the SMPS is well removed from configuration"?

Thank you for confirming that STM32U595 parts lacking SMPS do indeed erroneously show the warning message. Glad to learn I wasn't hallucinating after all.
