I am trying to setup USB host(controller 1) for communicating with usb device(CDC)(controller 2). USB host receives the cdc device serial number and device descriptor but could not complete the handshake ends up receiving NAK. Attached the figure for...
My goal is to rework the SD-card code with FatFS in non-blocking mode. When I start to read the SD card with the help of DMA, I have been surprised that the boot sector (sector #0) has somehow 'damaged' content (0x55AA signature at the end, but man...

Hello.Does any one by chance have working DFU program for visual basic ?I know that where is soirce code for C++, but it would take a lot of time to rewrite program in vbThank you i any one has working example
The bootloader is placed at 0x8000000 and the new application is at 0x08008000. I have attached images of the jump code and linker file.
