[RFC] re-queuing usx2y-fw

[RFC] re-queuing usx2y-fw

[Martin Langer]

Hi,

long time ago there was a thread about replacing tascam_loader.ihx with 
an open firmware:

http://sourceforge.net/mailarchive/message.php?msg_id=8555003

http://www.langerland.de/audio/usx2y/usx2y-fw-0.1b.tar.bz2

All results were quite positive and I've had a lot of downloads since 
them on my site and I never ever got a bugreport about it :)

What about a second attempt of merging it into alsa-firmware? Any new 
strategies for this step? The code still depends on as31 (8031/8051 
crosss-assembler) which still isn't available as .rpm or .deb, at least 
newer versions since 2.1. Should we care about it?

I use it on my US-122 since several months without problems and we have 
positive results from us224 and us428 owners. Even the size has only 20 
percent of the size of the original tascam file. Aren't these good 
reasons for deleting the original closed source file?

Another point is the license note in the README file for those Tascam 
files. Is it really true for tascam_loader.ihx? I (we?) know that 
tascam_loader.ihx and MidiSportLoader.ihx (for M-Audio MidiSport's) are 
100% identical; there's no difference. So I believe that this file is 
part of the same 3rd party development kit and is not be copyrighted by 
Tascam? I don't know it, but Tascam should know it better... just my 
two cents.


bye,
martin

No, I prefer the traditional one:  Send a patch :)

For convenience, we may include both the firmware source and binary in
the CVS repository, so that one can install even without as31.

Open-source version is _always_ good (if it provides the same
functionality).

If so, most likely you're right...

Ok. Do we have any CodingStyle for assembler files? FreeStyle?

Yep. I will try to introduce a new configure option like 
'--enable-buildfw' for it, or any similar solution.

Full ACK. And it does provide the same functionality here (loading the 
main fw).

AFAIK, nothing special.  We have no strict limitation except for
kernel drivers which should follow the standard coding style.

That'll be nice.

Here it is. The new configure option for alsa-firmware is called 
'--enable-buildfw'. If you want to build it from source you have to 
install one of the latest versions of as31, which you can find at

http://wiki.erazor-zone.de/doku.php?id=wiki:projects:linux:as31

(e.g. version 2.3.0 is fine)

Thanks, I added it to CVS now.

Could you prepare some document about as31?
Just mention the above in README of usx2yloader would suffice.

why not auto enabling it if we detect the non free as31 rather than
just providing such flag?

Of course, also including a small GPL copyright note.

+Building the firmware from source is possible, if you use the

BSD license is non free?

Is it really necessary to build it by default? I see a lot of trouble at 
the horizon due to version mismatches of as31. An as31 version check 
could solve it, though.

Agreed.  The resultant firmware should be 100% identical even if you
build by yourself.  Hence I don't think it's needed so much.

Controlling a checksum could solve that. md5sum? That would result in a 
table of as31 version and their related checksum. If someone wants to 
write it, go ahead :)
