Sentinel PX4 ( NO GPs Lock and firmware problem )

@Eric-Katzfey

no text file created

[tom]

@Samer-Jaradat do cat /tmp/test.txt, it probably was created

[tom]

@tom Or outside of the adb shell do adb pull /tmp/test.txt . to pull it off and upload that file here

@Samer-Jaradat said in Sentinel PX4 ( NO GPs Lock and firmware problem ):

gps start -d 7 -b 115200

Please change the line qshell gps start -d 7 -b 115200 in /etc/modalai/voxl-px4.config to qshell gps start and see if that solves the GPS issue,

@tom

no txt file created after do this command on my computer / tmp

[Eric Katzfey]

@Samer-Jaradat Don't worry about the text file. You pasted the output directly into the forum so that's just as good.

[Samer Jaradat]

@Eric-Katzfey
adb shell creat this result after do this command.

voxl2:/$ /etc/modalai/voxl-px4.config
bash: /etc/modalai/voxl-px4.config: Permission denied

[Eric Katzfey]

@Samer-Jaradat Don't try to execute that file directly. It is used by px4. Just edit it, save it, and then reboot your drone.

[Samer Jaradat]

@Eric-Katzfey

OK, but i don't know how we can edit it,
please tell me how i can edit it and save it.

[Eric Katzfey]

@Samer-Jaradat Please find a tutorial online about using the program vi to edit files in Linux.

@Eric-Katzfey

when i open vi program this is the result as shown on my pc i cant show the command that need to editing

GNU nano 2.9.3 /etc/modalai/voxl-px4.config

#!/bin/sh

PX4 commands need the 'px4-' prefix in bash.

(px4-alias.sh is expected to be in the PATH)

Figure out what platform we are running on.

Eventually there will be a utility called voxl-platform that will

return the platform tag or an error code. This utility is not yet

ubiquitous so it may be that it isn't available. Trying to call a

non existent program will generate an error code by the OS. If the

program exists and doesn't return an error code then use the results.

if [ $RETURNCODE -ne 0 ]; then
# If we couldn't get the platform from the voxl-platform utility then check
# /etc/version to see if there is an M0052 substring in the version string.$
# then we assume that we are on M0052. Otherwise assume M0054.

this is file open when i use vi program ( no command qshell gps start -d 7 -b 115200 in script file )
this is all file command :

uorb start

In order to just exit after starting the uorb / muorb modules define

the environment variable MINIMAL_PX4. (e.g. export MINIMAL_PX4=1)

This is useful for testing / debug where you may want to start drivers

and modules manually from the px4 command shell

Sleep a little here. A lot happens when the uorb and muorb start

and we need to make sure that it all completes successfully to avoid

any possible race conditions.

Start this first because it gets the high rate interrupts coming in to the

DSP. Without this the DSP will oversleep and miss critical timeouts.

Start logging and use timestamps for log files when possible.

Add the "-e" option to start logging immediately. Default is

show up as used then it is not reported to QGC and we get a
