Bad Parameter Table when running EKF Replay tool

When running the Replay tool I see the following:

./Replay – 2battfs.BIN
Starting
Processing log 2battfs.BIN
Using clock source IMU
Changing clock source to IMT
average_delta=2740.00 smallest_delta=1307 samplecount=1000
Replay counts: 144798 bytes 3417 entries
Replay rates: 5269789 bytes/second 124358 messages/second
check_group_info:206: suffix is too long in _TUBE_ORDER
Bad parameter table
Using an update rate of 400 Hz
Replay counts: 0 bytes 0 entries
Replay rates: 0 bytes/second 0 messages/second

Anyone know why it would be complaining about the _TUBE_ORDER parameter? Isn’t that a default parameter?

Is this on master?

I do recall this coming up previously…

3

I installed replay as described here: http://ardupilot.org/dev/docs/testing-with-replay.html

@peterbarker Would you be able to link where you have seen this before? It might help me figure this out.

5

Those instructions don’t cover getting the ardupilot repository.

What’s the output of “git log -n1”?

If you can provide a log I may be able to assist.

6

I believe the problem is there’s a parameter name which is too long -
ARSP2_TUBE_ORDER IIRC.

Issue doesn’t seem to have come up in my email. Might have been on
gitter…

It looks like it was last updated in April. I will try updating it and running the EKF replay again.

I just pulled the ardupilot repository and recompiled Replay:

~/ardupilot/build/linux/tools$ git log -n1
commit 2ba6f642813db043887a7eb1e06b82151609ec73
Author: Patrick José Pereira <patrickelectric@gmail.com>
Date:   Mon Jul 16 11:36:09 2018 -0300

Now it looks like it’s running until it says:

Barometer initialised
Segmentation fault (core dumped)

I’ve included the Replay.stg.txt (16 KB) file and did some snooping on where it was dying with valgrind:

Can you supply the log file, please?

Any thoughts on what it could be?

Is the problem resolved?
