Strange ISP Problem

2005-01-24 by Nice Guy

I'm using an olimex 2106 header board and I'm having problems getting
ISP to work.  The philips ISP program will not do a thing, simply says
unable to communicate with board when I try to read device ID or any
other opperation.  The lpc21isp program will not sync either, even if
I go in terminal mode the 2106 seems to freeze up.  However if I use
HyperTerminal I can type "?" and get the "Synchronized" response, I
respond with "Synchronized" then "14746" and can get part ID and
Bootloader version with no problems at all.  Still I didn't have a way
to load a program and test things out, So I moved to a differt
computer running linux.  I used the lpc21isp program under linux.  At
first there was no problems, I was able to load a program to blink a
led and that worked.  Later on I wrote some code and was going to try
it.  I started lpc21isp up on the linux box and it wouldn't sync.  So
I started lcp21isp up in term only mode and was able to send "?", but
only get back "Synchro".  Every time I try term only mode I get the
same results and still no luck on the windows box either.  To get from
TTL to RS232 levels I'm using a box with a max232 chip that worked
fine last semester with a msp430.  I have tried speeds from 9600 to
38400 and that has no effect.  Anyone have any Idea what could be
wrong?  What I really don't understand is why Hyperterm will work on
the windows box, but the lpc21isp in term only mode won't.
