Hello Team,
With RDP set to Zero Level , Firmware upload succesfully using CubeProgrammer GUI ( USB DFU mode ).
But If I set RDP LeveL 1 , Device not able to detect on PC device manager and not able to connect with STM32 using CubeProgrammer USB interface Option. It does not connect at all.
Hence , Firmware update not possible with RDP 1 using USB DFU.
After Setting RDP Level 1 to Zero using STlink V2 SWD interface , It works fine in USB DFU mode.
Is it the correct behaviour ? Everytime do we need to set RDP Level 0 using STlink SWD and Then use USB DFU ?
MCU is : STM32F303Rb
