+# Black pills
+
+I've been trying to flash these Black Pills I have (STM32F401), the official STM32 flasher worked great, [STM32CubeProgrammer](https://www.st.com/en/development-tools/stm32cubeprog.html).
+
+Run with:
+
+`./STM32_Programmer.sh -c port=USB1 -d firmware.bin 0x08000000`
+
+ `dfu-util` also worked, eventually, after an unspecified amount of messing around with udev rules (if it doesn't work for you out of the box, try the rs-probe udev rules).

+
+
+## This finally worked
+
+Clone the repo: https://github.com/stm32-rs/stm32f4xx-hal/ and `cd examples`.
+
+`cargo objcopy --release --example delay-timer-blinky --features="stm32f401,rt" -- -O binary out.bin`
+
+`dfu-util -a 0 --dfuse-address 0x08000000 -D out.bin`
