it's working.<br>
The charge pump is only activated once the uQ is fully booted.<br>
But I found out when starting the audio out test on the factory test
page the charge pump is activated and I get the correct -8V in the
analogue section.<br>

There is another 78/7908 pair in the analogue out section
in so8 cases.<br>
But the -12V for the 7908 is derived from a charge pump
that is not running until the unit is fully bootet.<br>
<br>
But I guess I'll get to that when the DSP test passes.<span

the microQ is a positive only design. No

There are 2 x 7805, a single LF33 and the

The datasheet says "These ROMs may be
factory programmed with data or programs
provided by the application developer."
No idea if waldorf went all the way to
burn a custom loader into these ROMs at
the chip factory.
At least the normal firmware should be
located on the flash, otherwise you could
not update it.

the 3.3V supply and it
delivers stable 3.3V
Xtal is running at 14.3MHz and
the Clock IC is forwarding the
clock to the DSP
I only worked with SHARC DSPs
so far, but I guess the
motorola DSP has no internal
program memory and is bootet
by the uC from flash and has
its OS stored in the attached
SRAM?
The rest of the PCB,
especially around the DSPs
looks pretty good. All sketchy
looking parts where located to
the left of the uC and the DSP
is on its right side. Caps
look good, too.
Here is a pic of the board.

I'm a bit concerned that the
firmware update does not seem
to work, as I guess the DSP
should not be involved with
that.
Maybe an indication that it
could be the flash indeed?
Any idea how to check the
flash?

I guess you already
checked everything round
that flip flop, resistors,
diodes etc... To me there
are also reasons to
suggest a problem with
power supply, maybe you
check that also before
soldering that dsp... And
think about the
possibility that it could
be the flash, also. Like
to hear what you are
discovering. Greets

I have a broken microQ
in the workshop right
now.
It arrived with a
scrambled LCD that only
showed garbage.
after opening it up I
saw someone butcher the
D-Flipflop (bend and
shorted pins)
after replacing it the
unit boots again,
waldorf welcome screen,
os2.2,
then preset name.
yay!
bad news is the unit
immediately freezes. No
buttons and encoders do
something. :(
I tried the firmware
update but on reveiving
the sysex data the power
button makes a quick
flash, 4 or 5 vertical
bars appear in the LCD
and
then nothing happens.
Pingpong chaselight on
the Inst. 1-4 LEDs and
the
message "please play
back dump" or something
like that in the screen.
In factory test mode all
buttons, LEDs and
encoders work.
Audio out test does not
work (silence on all
outs)
and the DSP test fails.
it only shows:
1:----- 2:----- 3:sig!
and repeatedly flashes
"DSP REBOOT" every
second.
So my guess is that I
have a broken DSP.
Is it worth it to try
and replace the DSP?
they are still in stock
at
digikey.
But I am open for other
ideas since I'm not keen
on desoldering the
LQFP144.
Best,
Julian
