Can I flash the STM32WB55xx M0 with a Segger J-Link

AHend · ‎2019-09-10

I have a dongle/dev board kit that I'm experimenting with. I updated and flashed the dongle's M0 chip via the STM32 Programming tool. Since I've already switched the dev board to J-Link headers, and have been flashing the M4 chip, I'm wondering if I can use J-Link to flash the M0 chip?

Or, is it limited to using the STM Programmer?

For now, it is recommended to use the UART and USB DFU methods described in "STM32Cube_FW_WB_V1.2.0\Projects\STM32WB_Copro_Wireless_Binaries\Release_Notes.html" to update the M0 chip stack, using the STM32CubeProgrammer CLI utility. In a few weeks, we will release another method for programming the radio stacks via the debug interface (SWD/JTAG) also using the STM32CubeProgrammer GUI. Third parties like Segger will probably soon follow but for now please use the recommended methods from the Release_Notes.html mentioned.

Regards
