Hi all, recently I layout a pcb with stm32w108cu64(copy from the MB954 Zigbee Domoboard)
But it seems doesn't work.
I try to use ST flash loader to connect the board, but fail. The I measure the VREG_OUT is 1.786V and the VDD_CORE is 1.497V. That's incorrect.
Acoording the datasheet, my board maybe just reset but not initialization?
Is the internal regulator the default Core power supply? Or how to initialize it.
Does anybody know? Help me.
Thanks.
