Hello,I'm looking for some troubleshooting advice. I saw a few tickets regarding this kind of problem and confirmed that __HAL_RCC_PWR_CLK_ENABLE() is called before setting the initial voltage scaling. This test code is completely auto-generated from...

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...

I'm unsure about my last observation, when I temporarily commented out calling HAL_ADC_Start_DMA(). At the time, that seemed to directly correlate to whether shutdown was entered/exited as expected. I don't have either the ADC4 global interrupt or th...

Sorry, it seems this had to do with overly long wires used as part of the test setup, when testing the production boards but not the dev board. Dialing down the SWD speed made the issue go away.

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 ...
