Flashing the BlackPill on Linux using dfu-util

If you read my previous post you know I was facing many issues to flash the firmware on BlackPill using the SWD programmer (STLinkV2, JLink, etc).

Finally I got it working! Let check it out!

These are the step to get NuttX running on BlackPill:

Clone NuttX and Apps:

$ git clone https://github.com/apache/incubator-nuttx nuttx
$ git clone https://github.com/apache/incubator-nuttx-apps apps

Configure and Compile the NuttX:

$ cd nuttx
$ ./tools/configure.sh stm32f411-minimum:nsh
$ make menuconfig  (### This Command is Optional ###)
$ make

It will create the nuttx.bin file!

Then I remembered that the STM32F4 family has DFU support, using it I was able to flash the board:

1) Remove the USB cable
2) Press and Hold the buttons NRST and BOOT0
3) Connect the cable
4) Release the NRST button
5) Wait 1 second
6) Release the BOOT0

$ dmesg

After flashing, connect the USB/Serial RXD to pin label A9 and the TXD to pin label A10.

Use the minicom or other serial console tool configured to 115200, you should see:
