bricked supervivi

So I have not powered up the device in about four months and now it is
dead.  I tried to see what is output on the serial console but nothing
showed up.  I can see the screen flash, but that is about it.  I am using a
generic RS-232 adapter and set the speed to 115200.  The device needs a
straight through cable and not the null modem one, right?

Also, how do people typically use the mini J-TAG board that converts
mini-J-TAG to 25pin parallel port?  I don't have a parallel port on any of
my machines.

Yup, it is a straight thru cable (mini2440).

parallel to USB or RS-232 converter?

So I think the device came with a straight through cable, and I was not
able to get anything when using picocom.  I will try to get another cable
tomorrow to see if it was a cable issue.

I assume that since the mini J-TAG adapter converts mini-jtag to parallel,
I would need a parallel to USB cable.

I never specified that I use a USB to RS-232 cable (which works fine).

So nothing gets over serial.  What JTAG tool do people successfully use
with this board?  I believe the JTAGing the NOR pdf mentions connecting the
parallel port to the JTAG connector.  Has anybody tried using a USB to
parallel port adapter?

It is connected via a little bit of hardware.  Did you not get the
accessories with the mini2440? Search <JTAG wriggler>.  Basically, one IC
on a small PCB, a parallel connector one end and a connector that plugs
into the JTAG port on the mini2440.

Ah, tool?  Do you mean software application or bit of hardware? H-JTAG on
the downloads page.

I got the JTAG PCB.  I am just curious if it is possible to use the USB to
parallel adapter to connect the JTAG PCB to the computer.  (I don't have a
computer that has a parallel port).  I can probably dig one up, but was
curious if the USB to parallel adapter will work with the H-JTAG software
and JTAG PCB.

Is there any kind of requirement on the parallel cable that goes between
the JTAG PCB and the parallel port?  I tried using a straight through cable
and the H-JTAG software could not detect the target.  I made sure that the
NOR was selected, and I hit the reset button (close to the power LED) a few
times.

Hi, RomanC,

From my experience, the parallel cable that goes between the JTAG PCB and
the parallel port of your PC must be very short, see 10cm. I encountered
this problem several years ago (not 2440) when I used a parallel cable 1 m
long. After changing to a short cable, everything became fine. 

You can have a try.
