I noticed that my pixhawk v2 was having some problems, so I hooked up the console in telem 4/5.

What I see at random are different problems:

  • Memory problems: this warning comes out "WARNING WARNING WARNING!
    Revision A has a silicon errata:
    This device can only utilize a maximum of 1MB flash safely!
    https://docs.px4.io/en/flight_controller/silicon_errata.html" but I havn't found any way to fix it.
    And it's not only a warning because later this happens:

"nsh: mount: mount failed: Out of memory
nsh: mkfatfs: mkfatfs failed: Out of memory"

  • Mavlink problems: I have a custom "extras" script to launch mavlink instances. In particular the script is the following:
mavlink stop-all
#ESP
#mavlink start -r 20000 -b 921600 -d /dev/ttyS0
#USB
mavlink start -d /dev/ttyACM0 -b 1000000 -m custom
mavlink stream -d /dev/ttyACM0 -s HEARTBEAT -r 2
mavlink stream -d /dev/ttyACM0 -s ATTITUDE_QUATERNION -r 50
mavlink stream -d /dev/ttyACM0 -s ATTITUDE -r 10
mavlink stream -d /dev/ttyACM0 -s HIGHRES_IMU -r 50
mavlink stream -d /dev/ttyACM0 -s GPS_RAW_INT -r 5
mavlink stream -d /dev/ttyACM0 -s GLOBAL_POSITION_INT -r 50

what happens sometimes at random is this error:
"INFO [mavlink] all instances stopped
INFO [mavlink] mode: Custom, data rate: 50000 B/s on /dev/ttyACM0 @ 1000000B
ERROR [mavlink] could not open /dev/ttyACM0
WARN [mavlink] mavlink for device /dev/ttyACM0 is not running
WARN [mavlink] mavlink for device /dev/ttyACM0 is not running
WARN [mavlink] mavlink for device /dev/ttyACM0 is not running
WARN [mavlink] mavlink for device /dev/ttyACM0 is not running
WARN [mavlink] mavlink for device /dev/ttyACM0 is not running
WARN [mavlink] mavlink for device /dev/ttyACM0 is not running
"

I really don't know where to start fixing it. Can it be all related to memory issues? Why isn't it able to open /dev/ttyACM0 sometimes?

PS: I tried to update the bootloader with https://docs.px4.io/v1.9.0/en/advanced_config/parameter_reference.html#SYS_BL_UPDATE without any success.

You're running out of RAM. You need to either stop some modules (unused mavlink instances for example), or get newer hardware with more RAM (e.g Pixhawk 4)

The Silicon Errata warning is about Flash, and is unrelated to the issues you're seeing.

But it's standard px4 1.9.2 code.
There should be a warning that it is unusable on pixhawk v2.

BTW "free" returns:

nsh> free
total used free largest
Umem: 238064 170320 67744 64576

It seems there is some free RAM.

Can you post logs from before and after your extras script runs?

What's on you SD card? Can you format it and try again?

There are only extras and logs.
Formatted it now with no luck.

All the errors involve the sdcard. What size is it? How is it formatted? Do you have another you can try?

It's a Kingstone 4Gb that ships with pixhawk.
BTW I switched it with a newer one 16 Gb, and it seems solved.
I'll keep you updated if it happens again. Thanks for the input.

mmm I said hurray too early. The problem is still there. It worked 3 reboots and now again at random.
I'm starting to think it's some hardware failure on the pixhawk.

@tuloski can you see the log output when it fails?

In the SD?

No, that would be with a console connected: https://dev.px4.io/en/debug/system_console.html

Yes, actually what I wrote in Case1 and Case2 are console outputs. Also when it fails I see it.

Adding some usleep of 0.5s here and there in the extras.txt seems to solve the issue.
Still not clear what the real issue is.

That's odd though because when it fails it doesn't even mount the SD card (from what I see in the log above).
