Hi,We are currently using H745 in our design and we noticed this little excerpt in the bootloader manual (AN2606):" Additional reset needed after power off/on to enable connection to the BL interfaces "It seems that not all resets are equal and the r...

Hi,I'm attaching a picture of my clock configuration and Logic Analyzer (Saleae Logic Pro 8) so it is easier to see what I'm doing.I have set the SDMMC clock divide factor to 1 in the configuration tab, which should produce a divide factor of 2 in th...

Hi @Community member Try changing these two lines: hfdcan1.Init.TxEventsNbr = 32; hfdcan1.Init.TxBuffersNbr = 32;to hfdcan1.Init.TxEventsNbr = 0; hfdcan1.Init.TxBuffersNbr = 0;You might be crashing your tx because you allocate too many elements ...
