Hello together,we have a board with an STM32H750I connected to a W25Q128 Quad SPI flash. We have our application code on the Quad SPI flash and run our application via XiP. This works fine. Now we work on our bootloader to update the application code...

Hey together,I have a question regarding the STM32H7 ethernet interrupts. I have lwIP + freeRTOS running successfully on the device. All fixes which were indicated by @alister were applied and it runs quite stable. The strange part is that when I ap...

Hello together,i'm using the X-CUDE-USB-AUDIO expansion pack with the Development Board STM32F769 Discovery Kit. We plan to integrate it later on into our product. The example project for playback and recording works fine. But we wonder which synchro...

Hey @GS1,thanks for your reply. It seems so that the FDCAN is not supporting this way of counting the REC down. I have contacted ST if there is a suggested way for it. The documentation on this part is very rare, so lets see what they say. Best regar...

Hey @GS1 ,I have similar problem like you have solved before. My FDCAN peripheral gets also into Error Passive mode, due to a REC >=128. Then i tried to switch to Internal-Lookback-Mode to receive my own messages to decrement. I can receive my own me...

Hey Andreas,wow option 2 is a nice suggestion and probably a very good solution for further projects in this field. Of course W25Q512 devices are way more expensive than W25Q128, but it could be very interessting if the dual image is 100% necessary. ...

Hey Pavel,thanks for your reply. Yes splitting it into chunks could be also a solution. This is a bit difficult now with a almost running application but we will think of. I also contacted ST to ask for thier proposal. As I think this could be a comm...

Hey all of you,thanks a lot for your fast support. Let me answer some of your questions. @FBL: The jump would happen in the bootloader. While this bootloader is running, it writes the new image of the application file to the address 0x9080 1000. Then...
