[Fixed] Hard Fault PC=0x0003199c

[Marxon]

Hi everyone,

there is a problem with my Midibox Sequencer V4 (LPC Core)

If i want to save a Track Event Preset, the sequencer stops working and shows the following error:

Hard Fault PC=0x0003199c

It creates a correct named preset but its empty (0 kb filesize)

But from time to time it saves it correctly.

I tried different sd-cards without success.

What couldt be the problem? I searched around the firmware files for this error code but it is not listed

and i dont really know how to debug it.

Thanks a lot for your help!

Do you have the latest firmware available on uccaps.de ?

Of course!

Additionally these are my SD-Card infos from the Sequencer:

Hi!

I have no such problem with latest firmware (LPC core, V4.058)anymore,

but on earlier versions was a lot problems with "hard faults".

Latest version works great by my side.

Best Regards, IGI

Hi again!

Hmmmm...

May some next release will fix this problem.

In the meantime i will use a text editor to edit my presets.

Best regards

Hi uCAppsers!

Happily I can report that with Seq V4.060 I have no more

"Hard Faults" during saving track presets :yes:

Did you change some code which was maybe related to this problem Thorsten?

Best regards

Marxon

I haven't changed anything to solve this issue, as I wasn't able to reproduce it.

Please let me know if it fails again on future MBSEQ firmware updates, it could be related to a memory allocation issue which causes memory accesses to invalid addresses (this will be hard to troubleshoot -> therefore "hard fault" ;-))

Best Regards, Thorsten.
