    • RE: Building some custom code to FC V2 - Bricked

      Unbricked! Here's some context/advice for anyone trying to do the same. If you purchased a cheapo STLINK V2 from Amazon as I did. Picture below...

      $0 Fix:
      What may very well happen to ya, is the RESET pin doesn't work. In this case you will need a friend. With said friend, you must dilligently connect to the board using Under Reset Mode and Hardware Reset. The second your homie clicks the connect button, you, the bricker of the board must move your jumper cable from the RESET pin which is 3.3V to an open Ground, leave it for exactly 1 second, then move it back to RESET. This should work like a charm, but may require one or two tries to get the right timing. See instructions below.

      $10 Fix:
      Program a Pico/Arduino to do your 1 second ground for you.

      $78 Fix:
      Buy the real STLINK V2.

    • Building some custom code to FC V2 - Bricked

      Hello,

      I've been successfully building and deploying binaries to the FC V2 over STM32CubeProgrammer for a few weeks now. On my most recent experiment I seem to have bricked the board, now my STLINK V2 will not connect to the board and I get DEV_CONNECT_ERR. I've tried hardware reset with the reset pin plugged into my link, in under reset and hot plug mode but no joy.

      I was very careful not to reconfigure PA13/14 for SWDIO and SWCLK. I'm in a bit of a scrambled mess now. If anyone has experience unbricking the FC v2 please let me know!

      Thanks!

    • RE: Building a Custom Flight Controller

      @Alex-Kushleyev, yes that would be the goal. I'm trying to identify where best it makes sense to run a custom flight controller in the current architecture. I realize I could do something external, but I would like to keep everything just to the VOXL2 using the I/O expander board for PWM output.

      I know this is quite a tough question that isn't very well defined, but I would really appreciate any advice if there have been attempts to perform similar things before.

    • Building a Custom Flight Controller

      Hello,

      Wondering if anyone here has worked on a custom flight controller stack not built on PX4, but which still uses Mavlink message standards.

      I just started on this effort.

      If so, I would like to know where dependencies might lie outside of the PX4 build. What VOXL data pipelines would break? Quite new to Modal's stack.

      Thanks!
