Managed to Resolve it For future people having pains, the best config seems to be: dtoverlay=miniuart-bt enable_uart=1 and remove the segment from cmdline.txt: console=serial0,115200 used ttyAMA0 I haven't tried using the gpio control flags as it seems it was depricated from the kernal, written my own using pinctrl for testing. gpio7 is boot0 gpio27 is reset pinctrl 17 op dh pinctrl 27 op dl sleep 0.1 pinctrl 27 op dh sleep 0.2 sudo stm32flash -b 115200 /dev/ttyAMA0 -v -w generic_boot20_pc13.bin...
