For DMA, allocating the buffer to the right memory segment,I am already allocating the buffer in to D2 (0x30000000), which I think should be right, and I haven't enabled the cache yet, for remaining all nonvolatile memory allocated in section D1 (0x2...

I have observed this issue (Unable to connect (& hence flash the firmware) the STM32-Cube-Programmer with STM32-target-board in USB-DFU-mode if loaded firmware is read-protected) on STM32CubeProgrammer API v2.1.0Whether above mentioned bug is resolve...

Yes, That's correct, STM32 uC Read out protection can be disabled in usb + dfu mode with command line interface only usingSTM32_Programmer_CLI.exe.Thanks for the confirmation.

Thanks for the reply,I have implemented in program, It works the way you have suggested.Please check the image.The only question I have is after executing HAL_FLASH_OB_Launch() I am not able to do further debugging.While debugging the code for the f...

Thanks for the reply.1) Do we need to always select target ID value to 0 (zero) while generating a dfu file from hex file (object file/uC build) using DFU File Manager, Please confirm?2) We are using our custom VID/PID in CDC class inside firmware fo...
