I have 9 or 10 Olimex LPC-P2106. They are great boards. They always had some problems with the Wiggler (needed speed 5 or above), but they worked. Recently, I've been unable to get any of them to work with a wiggler. I believe they are all rev B silicon. I have upgraded to the latest Philips bootloader (although I don't know why this would matter). I am running a genuine Wiggler with OCD Commander (I've tried several versions) on a 2.4GHz P4 (Dell Dimension 4550) running XP. The same setup works fine with my Olimex LPC-P2124 board. I don't think reset is the problem because I see the same problem on my 2106 based prototypes which have a real reset controller on-board. any ideas? --- In lpc2000@yahoogroups.com, "tsvetanusunov" <tusunov@m...> wrote: > > 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 > > IAR doesn't work correctly with Wiggler, this have nothing to do with > our boards > > > 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. > > how did you solved this? can you check if LPC2106 is REV.B? this may > be due to the famous LPC Flash latchup in the first lot we received > from Philips, this is nothing to do with the reset schematic but with > silicon revision bug on LPC chip > > > 2) Speed the computer speed is too high to handel the wiggler data > transfer > > which software this is related to? we have noticed IAR C-SPY works > well on slow computers and don't work on faster one, but this is > problem in IAR IDE not in our boards > > > 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 ! > > you are confusing something, Quadravox have no ARM compiler to the > best of my knowledge > > the bottom line is: > our boards works only with compilers/IDEs which work too ;) > - never experienced any problems with Rowley's IDE > - never experienced any problems with OCD when working in RAM > - from time to time working with IAR C-SPY (after number of retries > etc).
