Hard Fault during NGL upload

[Duggle]

I've suddenly started to experience Hard faults that appear to be happening during the NGL loading phase.

LCD 1 says:

!! HARD FAULT !!
at PC=0x0000011b

 

Up until this morning the whole batch upload of NG files has been extremely smooth.

I have only been playing with a couple of lines of my NGC around triggering a RunSection.

 

After the Hard fault, and power cycling, the NGL is present but empty.

I repeat the batch upload (which re-writes the Default NGC,NGL, NGR files all at once) and the midi box fuctions normally.

I repeat the batch upload again, and this time it Hard Faults, this time at 18%.

Power cycle.

Upload works.

Next upload HardFaults.

etc,etc.

So the pattern is that the upload after powercycle works, the next one fails.

 

OK (I think) I've found a cause!!!

Last night I had introduced a routine in ^Section == 0 that flashed some LEDs.

With this removed the problem has gone.

It is very confusing because the problem only manifests on the second upload process after each power cycle.

With the RunSection:0 removed I have uploaded repeatedly without the return of this problem.

 

It seems as though having executed at ^Section == 0 leaves the environment corrupted in some way?

In order to analyse such issues I need downstripped configuration file(s) which help to reproduce this at my side.

Ok, I've stripped down my NG files (a lot!).  Unfortunately, it now requires around 6 to 13(?) downloads before a crash. It is, from what I can tell, very repeatable though.

finally here's the upload batch file:

Mios_Studio --batch --upload_file=default.ngc --upload_file=default.ngl --upload_file=default.ngr

Thanks!

I was able to reproduce the issue, and think that it was related to a MIDI OUT access conflict.

The .NGR execution is protected with a MUTEX_MIDI_OUT now, and this seems to help.

 

Could you please try the latest version in the repository at your side?

 

Best Regards, Thorsten.

No more crashes but:

Its possible to trigger RunSection:0 from a button, but it's not happening at powerup.

What could stop:

if ^section == 0
exec_meta RunSection:2 
exit
endif

 

from triggering at startup?

[TK.]

This is probably related to a race condition while loading the files.

 

Regardless of this, I wanted to allow something like

if ^section == 0
  set ^section 2
endif

 

this would solve the issue on a more elegant way.
