USX2YLOADER - Second Phase Firmware loader for Tascam USX2Y USB soundcards
2003-09-15 Karsten Wiese <[EMAIL PROTECTED]>
GENERAL
=======
Usx2yloader is a helper program to load the 2nd Phase firmware binaries
onto the Tascam USX2Y USB soundcards.
It has proven to work so far only for the US428.
US122 & US224 will hopefully follow.
The snd-usb-us428 module requires this program.
US428 initialisation outlined
=============================
A. Phase 1
A.1. US428 is plugged to the PC and powered on.
This makes the kernel see a new USB-device with the Vendor/Product
ID 0x1604/0x8000.
The kernel reacts by starting the usb-hotplug script.
A.2. The usb-hotplug script starts the executable fxload,
which transfers the EZUSB firmware to the US428.
A.3. The US428 disconnects itself from the USB-Bus and ... (see Phase 2).
B. Phase 2
B.1. The US428 reintroduces itself as USB-device with the Vendor/Product
ID 0x1604/0x8001.
The kernel reacts by loading the module snd-usb-us428, if it is not
already loaded.
B.2 The module snd-usb-us428 "takes" the US428 as its device and sets up
a "hardware dependent interface".
(The module doesn't create any pcm nor midi devices now.)
B.3 Subsequently the kernel starts the usb-hotplug script, which launches
usx2yloader.
B.4 usx2yloader transfers the 2nd Phase firmware binary to the US428 by means
of the "hardware dependent interface". When this transfer finishes,
the snd-usb-us428 module creates the pcm- and midi-devices.
Initialisation is complete.
USAGE
=====
When usx2yloader is invoked without options, it will probe all existing
soundcards until a valid USX2Y-driver is found. If a valid USX2Y-driver is
found, usx2yloader reads the board type from the driver. The corresponding
firmware binaries are then read and transferred to the driver.
Finally, usx2yloader initializes the PCM, MIDI and the mixer devices on the
driver for making the soundcard full functional.
Instead of auto-probing, you can specify the card number or the hwdep
device name or the usb device name via -c, -D or -u options, respectively.
% usx2yloader -c 1
% usx2yloader -D hw:0
% usx2yloader -u /proc/bus/usb/001/003
For loading everything automatically in response to a hotplug event
there are the hotplug script files
- tascam_fw.usermap
- tascam_fw
- tascam_fpga
and the Firmwarefiles.
You also need hotplug to be installed.
FIRMWAREFILES
=============
The firmware binaries are installed on /usr/share/alsa/firmware
(or /usr/local/share/alsa/firmware, depending to the prefix option of
configure). There will be *.conf files, which define the dsp image
files for each different card type.
