Finally I got to put together my Igore board. I am having
hard time connecting to it. Its my first experience with a
pic (18f452). I tried Martins' boodloader (colt),
microchips' and tiny pic boodloader with the provided
schematic for a programmer.
Non of them seemed to recognize the pic. I am not sure what
am I doing wrong. I double checked all my circuits. Any

- Hi Attila,
Igore I or Igore II ?
Igore II I'll assume.
You may not be aware that there is a small bit of
firmware that must be programmed into the PIC via
regular firmware programmers to use a booloader. Do
you have a PicStart Plus, or Warp, programmer to load
this onto the PIC? Just starting at first principles
... so if you know this please disregard.
I use the Tiny Bootloader quite a lot, it should work
fine on the '452. How are you getting the bootloader
into the PIC? Are you sure the programmer is working
correctly? I used the Wasp628 thing on Igore II, but
once you load the booloader with it you can just use
the regular serial port.
If you need to have someone load the bootloader
firmware onto the PIC for you you can always drop by
my place (Kanata, if that is handy).
If that isn't the problem, there is a RS232 disable /
enable jumper on the Igore II (JP25) it must be in
place to powerup the MAX232.
Also what kind kind of serial level converter chip are
you using, I seem to remember some problems with some
of the ones from ST ... try a MAXIM Max232 if you are
using the ST.
And of course the lame power on ... wiring triple
