[ANN] Open Source US-X2Y firmware

[ANN] Open Source US-X2Y firmware

[Martin Langer]

Hi,

if someone is interested in a free (I mean GPL) firmware for the Tascam
US-X2Y devices I can offer an open source replacement for the second stage 
loader alsa-firmware/usx2yloader/tascam_loader.ihx. All three US-X2Y devices
need this file. But I have only tried it out with an US-122 where it works.

Be careful. This software comes with ABSOLUTELY NO WARRANTY!

does it here with an US-428 without any problem.
Good stuff!

shall i include this into alsa-firmware?
or should wait for a while until more debugging?

In which way should it be included?
- replacing the vendor fw file
- as alternate fw, maybe with a configure option like 'prefer-free-fw' or so

Another point is that MidiSportLoader.ihx is 100% identical with
tascam_loader.ihx. Maybe midisport devices work with this loader too. But I
have no possibility to test it. Then it would be better to remove the ezusb
stuff from usx2yloader and create a new chip specific tree for all ez-usb
devices. Or not? 

> or should wait for a while until more debugging?

I guess some us224/midisport test would be nice. But on the other hand the
loader core is built into the chip and my code is not much more than a few
init lines.

Ok, now we know that us122, us224 and us428 are working.
So I vote for replacing tascam_loader.ihx :)

Apropos Midisport: What about a free midisport firmware package? A
combination of the gpl firmware by Lars Doelle and this loader. But perhaps
this loader fails for midisport devices --- it's still untested, it's just
an idea. On the other hand it looks like everybody is happy with the
alternate loader from http://usb-midi-fw.sf.net --- file it under $0.02 ;)

Great.  Could you send a patch?

Sure. It's attached, but I'm still unsure: A patch for alsa-tools/usx2yloader
or alsa-firmware/usx2yloader? Is it divided by license or by loader/firmware
separation? I've choosen alsa-firmware/usx2yloader/src.

I guess many users will get trouble because they haven't yet installed a new 
version of as31 (v2.2). BTW, I haven't found any deb or rpm :(

Nevertheless the one and only as31 tarball I found is available here:
http://www.erazor-zone.de/ez/execute/explorer.php4?dir=..%2Fprojects%2Flinux%2Fas31%2F&view=small_icons

But it works!

Then it might make sense to include either the loader binary or the
assembler into the alsa-firmware package.
(http://www.pjrc.com/tech/8051/ says that AS31 is provided under the
BSD license)

I've tried out some versions of as31 and the code works with the latest
versions: 2.1, 2.2 and 2.2.1

Earlier versions including 2.0-beta3 from http://www.pjrc.com/tech/8051/
fail.

Including as31 into alsa-firmware is the wrong way IMO. Fixing assembler
bugs shouldn't be the goal of alsa in the future. Also, the number of
compiler tools will grow. Each card has a different chip and need different
cross-compiling tools. And I believe in three years we have no longer cards
without firmware.... perhaps five years ;-) 

It looks like a general problem, because development tools for firmware files 
can be exotic, if they exist at all. Offering two packages firmware-bin and
firmware-source sounds much better.
