Hello,I've successfully used the code below to enter shutdown on a U585CIUx. It wakes up on button press and I can tell it is coming up from reset because of timestamps (based on time since startup) and terminal output that only happens during startu...

Hello,I'm porting code that worked on STM32U585CI using SPI1 as full duplex master with GPDMA1 CH4(Rx)/CH5(Tx) to an STM32U585QII using SPI3, again as master with GPDMA1 CH4(Rx)/CH5(Tx). Only 1 SPI is used. I'm using CubeIDE 1.13.2 to autogenerate HA...

Hello,I've seen other posts provide links to examples for "USB host application based on the Audio OUT class". Are there any for audio in?Thanks

Hello,We have the RCC_LSCO of the U5 connected to a peripheral that warns that it will pull this line to ground when the peripheral itself is reset. At the moment, the pull strength of this peripheral is unknown, but let's say it's fairly strong.Does...

Hello,The STM32U585 Reference Manual say these chips have one AES and one SAES peripheral. In turn each of these have an "AES core algorithm (AEA)" component. I expect that to mean that there are two physically independent AEA's on the chip. Is that ...

I had continuous DMA running for ADC so once I stopped that, the shutdown behavior started working as expected.

It turns out that the answer to this is this ticket , which explains that HAL_PWREx_EnableVddIO2() needs to be called in order to enable PG[15:2], which in my case relates to SPI3's SCK and CS GPIO.It would be good for the IOC to either auto-generate...

Hi @STTwo-32 ,I've been looking at that too, although the examples it contains are for USB Device rather than Host. I'm going to see if I can mix, match and adapt with what I've come across so far, but I'll keep this ticket open a bit longer just to ...

Hi @AScha.3 ,I'd like to wrap back to my initial concern about impact to the oscillator. So let's say we have the 560ohm resistor in line, the peripheral pulls down the line to ground, and the CPU is protected. Does that also prevent any impact to th...

Hi @AScha.3,Certainly we want to take the necessary steps to protect the CPU, but it'd be nice if that came for free as part of the U5 without having to pay additional cost and space for any extra components. Is it the case then that the CPU doesn't ...
