I have a project that uses DMA in circular mode, and i've implemented the half and complete interrupts necessary to manage the transfer. I'm using just 2 nodes, and I've noticed that I get a complete interrupt to start the transfer, and then the exp...

The manual I have for the STM32U585 describes the Independent Watchdog (IWDG) peripheral and says it has an Early Wake-Up Interrupt (EWI) feature. The manual says "Wake-up from Stop with interrupt is supported only in Stop 0, Stop 1, and Stop 2 mode...

We have been using an STM32 U585 with additional external FLASH connected to OSPI1 and external PSRAM connected to OSPI2. This is not on a dev kit, it is our own hardware. The PSRAM is memory-mapped and is using the HyperBus protocol. We have noti...

I'm using a STM32U585 that has some hyperRAM attached to OSPI2. I've memory mapped it and it's working well during normal operation. I've noticed, though, that when I leave it powered and put the processor into Stop 2 mode, it corrupts some of the ...

I have a project that I'm compiling for the STM32U585QI, which has a dual bank architecture with two 1MB banks. My project has gotten large enough that it's going to spill over into the second memory bank. Are there any issues with running code tha...

Thanks! Is there a good way to configure the DMA so it doesn't throw this initial TC interrupt? Or a way to tell which linked list node is active when the HT hits, other than keeping track of what I think it should be?

This is on an STM32U585QI

The ram we're using is an Infineon S27KL0642. We've scrutinized the settings for our application and clock setup. I should mention that the code will run correctly for days on end. We've just found a specific test case that produces this skipped r...

Unfortunately the code is not something I can share in full. I've included our OSPI2 setup code where we memory map it. We are running the memory at 80MHz, slower than its max 166MHz. This issue is reproducible on multiple devices, so much so that...
