[GayaBigFoot]

Hello

I am working on wb55RGV6 nucelo, I have bought nucleo revision C and I was able to flash it with stmcubeprogammer (stm32wb5x_FUS_fw_1_0_2.bin).

I have had a new ,nucleo, a D revsion and I can't flash it, i can't delete firmware, I have tried to apply values's nucleo C revision ​​in option byte and that tells me the following figure

Notice : the first screen is showing the defaults values, the seconde is after i set the value's nucelo XB55RGV6 C revision.Could you help me please?

Thank you

I have resolved the problem, I used StmCubeProgrammeur, I clicked on " start FUS" first, then I deleted the  firmware, finally I have upgraded the FUS.
