Unfortunately, this did not work. However, thanks to the debug UART output, I managed to find the issue. There was something wrong with the de-initialisation of the OSPI in the write function. No idea why this only happened when writing the second ti...

I made some more experiments and it seems like the data is not correctly written to the flash from CubeProgrammer. When I write a bin file containing 16bytes "0123456789abcdef", it actually works and I get the message "file download complete" and the...

Hi @Imen.D,Thanks for your answer. I already saw that post and tried the suggested modifications but they didn't help. That's also the reason why I switched back to CubeProgrammer v2.6.0.Maybe the template I used from the following repository is not ...

Thanks for your answers. And who controls the pull up/down resistors on the DP/DM lines to indicate the host a device is connected? Do I have to take care of that separately or is it handled by the driver when I enable the USB?

Custom External Loader fails: Error: failed to download Segment[0]

I want to add a USB CDC driver to my application on a STM32F446 (self powered device). However, I had to use the dedicated VBUS pin for another function.
