I am having trouble saving any parameters to my Pixhawk (none of them survive a reboot). I have been digging in the code to understand what is supposed to happen, but I am afraid I’ll need some help to solve this.
I have tried this:
Setting from QGC console:
Setting the airframe, selecting “apply”, then “apply and restart”. After boot, the parameter is still 0.
Setting from mavlink console:
nsh> param set SYS_AUTOSTART 7001 SYS_AUTOSTART: curr: 0 -> new: 7001 nsh> param save
After restart, the value is still 0
- I have flashed developer build from QGC (I get the same problem with other builds)
- SD card seems to be working “ls /fs/microsd/” correctly lists the contents, and I can both create files and read them from a computer (with microsd adapter)
- I have only the debug console connected at the moment.
- During boot, I get an error from the parameter importer, see boot log below
- I have got the toolchain set up and I am a fw developer myself, so please let me know if you have an idea on how to debug this from with code.
- If I export parameters using “param save /fs/microsd/out.txt”, I only get a seemingly incomplete file containing only one line:
" _V_VOLT "
Bootlog (over system console)
