Hi,
The STM32F4 does not have a DMAMUX so peripherals use specific DMA channels, you need to check the Reference Manual and see if there are alternative channels that can be used in your case. There is a table with mapping in the DMA chapter.

Re: UDP receive missing messages
The PHY could require some extra initialization.

Re: [HELP] STM32H750 USB HS ULPI Support,
It could be a SW issue, ULPI has not extensively tested.

Re: UDP receive missing messages
Do you have a MACv1 board to try? (anything except H7).
Not sure how to test this.

Re: UDP receive missing messages
Next step is to understand if there is a driver problem or an HW issue. Are you using MACv1 or MACv2?

Re: UDP receive missing messages
You should try to verify if it is the MAC driver delaying the frame or if it is a problem within lwIP or its integration layer.
One possible approach is to flip a GPIO from the MAC ISR, send periodic packets and look with a scope if the ISR occurs immediately.

Hi,
Thanks, this could be related but currently I don't have HW to test this.

Re: A-D "Linear Buffer" conversion on 32L031
Hi,
There are other conditions where "cont" must not be specified, those register settings are meant to be "low level".

Re: A-D "Linear Buffer" conversion on 32L031
I think you need to specify ADC_CFGR1_CONT.
