ISP to ICP using LPC936 - lopesjm_lpc - Mar 31 16:39:14 2006

Hi !

I build a lpc9xx programmer. The ISP mode it's fine, but I can't to
program lpc915 with ICP mode. I downloaded the Bridge source code and
recompiled with reg935.h, because I have a LPC936 to Bridge.

My circuit don't work to program ICP mode. I programmed lpc936 with
the Bridge code, but the VDD and reset control pins don't work.

Did anyone use LPC936 as Bridge ISP to ICP ?

Thanks in advanced
Jorge

Hi !!

My ICP programmer it's work now. The cable with the ICP signals must
be shielded and small.

Now, my problem is to erase all memory LPC915. The FlashMagic don't
work, and show error message:

Operation falied. (erasing device)

When I select all blocks (not all memory command), the erase command
works.

Does anyone have the same problem ?

thanks
Jorge
