I have a query regarding firmware upload. I get the Erase, Program and Verify lines mentioned below. However I do not get the Rebooting line. Apologize for this silly question. I just want to receive a thumbs up from someone regarding this.
Thank you for your time !
Good day, In which way did you upload the firmware? is this for flight controller or a peripheric?
This is for pixhawk. When I implemented the command,
_“make px4fmu-v4_default upload”
ok… which version of Pixhawk do you have,
It is 1.8 @Dave84. I did “make px4fmu-v2default upload”
ok, before you upload the firmware you must check first the version of your flight controller.
Pixhawk v1 work with px4fmu v2, pixfalcon with px4fmu-v3,pixracer with px4fmu-v4default, pixhawk v4 by holybro with px4fmu-v5
Yes ! I did -v2 since my pixhawk is of version 1. Am I doing anything wrong ?
You are uploading the firmware with usb… jtag or dfu?
ok…after you have done the update you can hear the music tone
No, I cannot. However I see the “ACT BUZZER” light blinking.
can you send me pls a small video of the procedure you are doing
Hello ! So weird, now am getting the rebooted line. All good now. Thank you very much for helping me @Dave84.
Thank you @Dave84 ! Just started working on this. Adventure awaits…
I flashed FW on my Pixhawk Lite 2.4.6. After reboot I’m unable to connect to it via MAV.
Before this it’s used to work, but after I upgraded bootloader from FMU2 to FMU3 I ended up in this.
$ ./px_uploader.py --port /dev/ttyACM0 --force ./px4_fmu-v2_default.px4

according to your dmesg you are connected to your pixhawk. When you say “connect to it via MAV” are you using qgroundcontrol or custom software? Either way, try to see if you change your serial to read in /dev/ttyACM1 instead of /dev/ttyACM0 (which is usually the default).
I am no expert, but I have run into similar issues before.
I hope this helps!
