I have connected my pixhawk directly to my computer through a USB cable and I am able to connect to my pixhawk. I am able to change most of the settings in the setup tab (I haven’t tried all) but every time I try to open up the serial port tab, it doesn’t work (image above). It loads for a bit with a popup saying “trying to download uart.txt from FC” (another image) and then just fails
(I don’t know if this is relevant but I plugged my sd card into my computer and I couldn’t find a uarts.txt file)
Sorry for my mis-interpretation on the subject:). Regarding the flight controller, it’s a brand new pixhawk but a sd card from an old pix hawk ( both pixhawk 2.4.8)
Firmware isn’t stored on the Sd card. Try the Pixhawk1-1M version.
Which actual 2.4.8 Are these? It doesn’t make much sense if they are new units that fmuv3 or pixhawk1 doesn’t fit as that’s what was on there. Unless they are Radiolink units in which case throw them in the trash.
