Re: JTAG problems with Olimex LPC2106

2004-09-30 by bobi catorski

Hi 
 
I once encunterd the same problem with the Olimex bord & wiggler 
and  the OCD and it dosen't worked well (only reset work via the software) the same problem encunterd with the IAR C compiler when used with the Olimex LPC2106  board  & wiggler 
 
As I recall  the problem can be divided in to 2 categoris 
 
1) Reset problem : the Olimex board use simple RC type to reset the CPU 
    I don't remember the chip (LPC2106)revision but as i can recall the first chip revision 
    use to have reset problem couse the chip to hang up. 
 
2) Speed the computer speed is too high to handel the wiggler data transfer 
 
I manage to overcame the problem using the qudravox C compiler as I can recall it work well with the Olimex wiggler and LPC2106 board !
 
Regards 
 
Bobi

I'm having trouble getting my JTAG Wiggler to work
with an Olimex LPC-P1 (2106 based prototype board).
It works fine with my Olimex LPC2124 based prototype 
board, but always gives me a "cable disconnected" or
"cannot enter debug mode" error. The board resets
properly when I start OCD Commander or ocdlibremote, 
but then enters full run mode. I have tried this with 
the DEBUG jumper on and off at all possible speed 
settings for the Wiggler.

Is anyone else having this problem?
