Wiggler

Started by gustavo_sagasti February 7, 2004
Hi:

I have a Wiggler from Macraigor that came with a Triscend (8051
embedded + FPGA) SCoC Dev Kit.
Does someone know if it would be compatible (may be configuring an
internal jumper...) with Crosswork (from Rowley) or Keil Debugger?

Thank in advance...

Are you sure it was a Triscend 8051? They also do an ARM system, which comes
with a Wiggler, IIRC. Or, perhaps they have JTAG on the 8051, also. I think
Triscend was recently bought by ARM, BTW.

It will probably be OK. The other Wiggler versions (they all have the same
basic PCB) are for PowerPC etc. You could just try it and see if it works.

Hi Everyone,

I build myself a wiggler, I used the schematic from sobellinni, but
I used a 74HC244N, put 5v on the VRef. I configured my board, but
OCD Commander says the cable is disconnected, ocdlibtool connect on
a certain configuration of the board (but actually not the right
one) but I get al kinds of errors. Is there something wrong with the
schematic, do I use the wrong chip/voltage, or do I use the wrong
software?

Regards,

Theeuwke

Try my schematic and PCB design: jtag.zip

That works OK for me.

uh, ok, but the ondly diference is 1 extra resister, but I will put
it on my board. And, I use a BC576C for the Transistor. What do you
use for voltage on the 74HC244 ? (pin 20)

It should be OK then.

What do you

It should be supplied from pins 1 and 2 on the 20 way header that connects
to the target board (3.3V).

Mmm, it resets good now, but I have still some problems. I put some
little program on the board to enable the JTAG port (i have to use
the second), but when I try to do something in GDB it is still
complaining that the processor is still running. 2nd; OCD Commander
is still saying he can't find a wiggler. Here's some information
about the configuration of my board:

I use this board:

Have a look at these notes of mine:
http://webspace.webring.com/people/jl/leon_heller//lpc2104.html

Check on your Ashling board that DBGSEL and TRST are tied high and the LPC
bootloader is disabled (P0.14 high).

Something else I just remembered: you might have the interface speed

construction; mine works faster than a genuine Wiggler, probably
because I took more care with the PCB layout.

I tried al the speed settings, no luck.

I Just putted a scope on it, Result when i connect with ocdremote:
nRST: pull up
TDO : pull down
TCK : some data i think
TMS : clock
TDI : nothing

TRST = HIGH
DBGSEL: LOW! - > put 3.3 on it?
