I don’t really unset what your asking…

There was a problem with the serial ports on RPI3. It was fixed in firmware recently. Do an rpi-update to get the fix. /dev/serial0 was being linked to /dev/ttyS0 in some cases, and the baud rate was being throttled. force_turbo=1 and/or cpu_arm=200 would fix the throttle issue, but /dev/serial0 was also added as a comsole in some cases. New udev rules and other logic now prevents this. I can post a link if necessary. The update fixed my Pixhawk to RPI3 issues.

Could you post a link to this? Thanks

  1. disconnect the power to the raspberry pi.
  2. connect the usb-to-serial to the raspberry pi: just ground, tx and rx.
  3. Plug the usb-to-serial into you computer
  4. type “ls /dev/tty.*” and identify the usb-to-serial device
  5. type, for example, “screen /dev/tty.PL2303-00004326 115200”
  6. Connect the power to the raspberry pi.
  7. Notice numbers received on the display from the raspberry pi.
  8. Issue the upload command using Ctrl-A followed by “: sx -kb blinker.bin”

I find this in a website, but I don’t know how to get “screen /dev/tty.PL2303-00004326 115200”
