Hello everyone,I've spent a considerable amount of time trying to change the default AES and ECDSA (ECCKEY1) keys, but I can't figure out why it always results in a 'Fw header authentication error' during the firmware image update process.The project...

I have the latest X-CUBE-SBSFU package and STM32CubeIDE 1.13.2. Building the SECoreBin project has failed with 4 errors and 4 warnings. It looks like several others experienced the same issue with different example projects.Here's the output of the c...

The following two designs were generated by EDS: Could someone please advise which one is more recommended for powering a LED strip? And can you suggest any off-the-shelf transformer PN that can go with any of these designs?

Hello everyone! I was wondering what might go wrong with I2S DMA configured in normal mode for audio streaming with double-buffering technique. I'm not talking about circular buffer here (ping-pong) where a single buffer is used in halves in HC and T...

I believe all of the audio processing addon libs, (SRC236/SRC441) are built without hardware FPU support. The problem is my entire project was built with hard FPU support. I tried the mixed SW/HW, but that didn't solve the issue and I couldn't build ...

*** UPDATE ***I believe I have found a solution, or more likely a workaround for this. I will try to share details later in case someone is facing the same issue in firmware authentication after changing the default keys. It all had to do with the sc...

I can confirm that I have the same issue with a project built with HAL 1.28.0 for F4.USB_CoreReset() always times out which prevents the USB stack from getting initialized. I have generated another project with basic code for testing, USB MSC in host...

The following option: 'NO_SW_VBUS_DRIVE_FS' in the latest version of STM32CubeMX has solved this issue!

I just experienced the same issue with CubeMX 6.9.2, as I generated the project files for Keil uVision, my custom sources were vanished. The problem is, these were not added from another project. They were sources I was working on for the past 8 hour...

Well, 100 MS/s is not a requirement at all. I was just referring to what 'GPIF' was capable of in another silicon. However, the behavior of the interface and how it's implemented is what concerns me the most. Aside from DMAMUX and the many other opti...
