Firmware Upgrade with SD Card?

GFlight_1 · April 10, 2019, 3:25pm

Hi guys, I have a Pixhawk (not cube version) that I run in a plane that has a pretty old firmware in it because the USB port is broke (connector broke off) so I can’t load new firmware onto it. I am wondering if I can upgrade the firmware through the SD card? I have searched around and found where people say you can put the Pixhawk into bootloader with the switch but how do I get the Pixhawk to read a firmware upgrade from the SD card? If anybody has a workflow that would be appreciated.

Thank you for your help.

Wouldn’t it be easier to just get an External LED/USB cable so you can also make any parameter changes anytime?

Good luck.

Yes, that sounds great and thank you for the link. Will that USB connection work the same as the micro USB that broke off when I do a firmware upgrade or is there anything special I have to change?

Thank you.

Yes, it’s Plug n Play, plus you’ll get an external LED as well.

Good luck.

To answer the original question, no the SD card does not have a means to load firmware. It’s only function is storing logs and terrain data.

Thank you Matt, that is also good to know.
