Cant run the 1st code on Snapdragon

[anujkumargupta]

Hi
I am working with Snapdragon FC and trying to run my 1st code as mentioned in dev.px4.io.
I have build the code using make eagle_default and uploaded it in FC but when i am running the code found this error

root@linaro-developer:/home/linaro# ./px4 mainapp.config
sh: 1: cannot create /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor: Directory nonexistent
commands file: mainapp.config

Earlier i was getting the same error so i had build all the cross toolchain installation and build the code using make but again same error.

Mini-DM is not showing anything

Have you updated to the BSP 3.1.1 and the latest adsp image?

[Stifael]

same error, but also have timer difference too big

[anujkumargupta]

Thanks @julianoes ,
Yes updated the linux image to BSP 3.1.1 and pushed the latest ADSP firmware , both downloaded from intrinsyc about 15 days ago.

[julianoes]

@Stifael: does the error persist with thr latest BSP and adsp image?

[julianoes]

@anujkumargupta and @Stifael: I can't reproduce the error, it works for me.

Can you list down all the commands you entered, maybe I can spot what you're doing different.

[anujkumargupta]

HI @julianoes Today i just tried a different thing instead of pushing the q6-admin.sh i edited it in adb shell and now it works fine but still the Ground control station does detect it.
I tried to run mini-dm but didnot able to under stand

here is mini-dm output

Do you always get this FIFO overflow output, even after a reboot and a power-cycle (disconnect all power)?
Please post the output of the shell and mini-dm. Also, is the networking setup correctly? Can you ping the device?

This time i didnot get the FIFO overflow output

i tried to connect it using wifi module but the signal is very week (even when i kept it at a distance of max 20cm) and ping output shows destination host not reachable

How to increase its signal strength

[julianoes]

Do you have an antenna connected to the Snapdragon? This would increase the signal strength. However, for testing I use it without antenna and it is usually good enough for a few meters.

[julianoes]

@anujkumargupta it looks like the first error is gone though:

[platforms__posix__px4_layer] krait update param 664 failed

Do you know what you changed to resolve it?

[anujkumargupta]

Hi earlier in pinging it shows error because i also connected my lan cable but after removing the lan i can ping the device.

but the adb shell and mini-dm output is same
Thanks

[julianoes]

Ok, good so it was a routing issue.

The adb shell and mini-dm output look ok. It is just complaining that no external mag is connected but it will fall back to the internal mag.

I would expect that QGC shows something now, no?

[anujkumargupta]

Hi @julianoes
Yes this [platforms__posix__px4_layer] krait update param 664 failed error is solved.
Earlier i was trying to pull the script and then edit and then pushing it.
adb pull /usr/local/qr-linux/q6-admin.sh
gedit q6-admin.sh
adb push q6-admin.sh /usr/local/qr-linux/q6-admin.sh
But later i edited it directly through adb shell
vim /usr/local/qr-linux/q6-admin.sh
and also done all step without removing the board even once.

[julianoes]

Ok interesting, I'll try to reproduce this. In theory both "editing" variants should lead to the same.

[julianoes]

@anujkumargupta you were right! If you do adb pull and adb push the executable bit gets lost.
Fixed with PX4/PX4-Devguide#55.
