> 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). IAR are aware of this problem, but they just refuse to support our low cost JTAG to may sell their 300 EUR Segger's J-LINK with their compiler Best regards Tsvetan
