Hello @Nluke.1​ ,

Welcome to the STM32 Community :)

I advise you to refer to this article and Video: How to program a STM32WB55 with STM32CubeProgrammer.

Hi Imen,

I understand that i could program the STM32WB55 with STM32CubeProgrammer and ST-LINK.

my need is that we should use our product to program the STM32WB55 offline. our product has reserved JTAG/SWD interface to program the chip. but the STM32WB is not like the general STM32 chips with only a core , i could not access the flash. now i could only read the JTAG id of CPU1(M4).

So i want to know is there any special document for programming this chip.

thanks a lot

Luke
