STM32G474 DMAMUX Overruns: Why a Clear Flag Can Hide a Lost Trigger
Can a G474 request-generator pipeline lose a trigger without leaving an overrun flag, and how should timing and concurrent channels be constrained?

STM32G474 USB-C Cold Start: Preserve Dead-Battery Detection Until UCPD Takes Over
Why does a G474 USB-C sink fail to power up from an unpowered state, or detach when firmware takes over the CC pins?

STM32WB FUS Binary Selection: Identify the Installed Service Before Choosing the Upgrade File
Which FUS binary matches the actual installed service version and WB device, when the factory inventory contains different starting states?

TinyML Model Storage: Keep Embedded Model Bytes Readable for the Interpreter Lifetime
Explain why TFLM constants can retain direct FlatBuffer pointers after allocation and how generated array placement or external-memory mapping affects inference lifetime.

STM32H563 TrustZone DMA: A Completed Transfer Can Still Contain Blocked Accesses
Why can an H563 DMA completion coexist with zeros or an unchanged destination after security attribution changes?
