Make sure you have specified your gcc-arm-none-eabi binary location in the Makefile ("PREFIX = ...") (version 7 works, there is a version that does not!) (if the ons in linux repos do not work, use the official version: https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads). Right to the STM32, there is a debugging header with GND, 3V3, SWDIO and SWCLK. Connect GND, SWDIO and SWCLK to your SWD programmer, like the ST-Link found on many STM devboards. Make sure you hold the powerbutton or connect a jumper to the power button pins while flashing the firmware, as the STM might release the power latch and switches itself off during flashing. Battery > 36V have to be connected while flashing.
