For same subject I posted a thread in flash magic forum. There was no reply.
Although I can flash a new P89LPC9408, still I can’t re-flash the same IC.
I am using ISP method.
When I power on my hardware for re-flashing , its start executing already flashed program.
Can u send me the exact steps that I can follow in the ISP method to re-flash the same IC.
I am using flash magic version 3.65.
When I start boot loader Boot command - “Operation failed â€" no echo “.
Thanks & Regards
Please provide me that method to kick the chip into ISP. Because I flashed many units without your NOTOUCH stuff. I want to reflash them. Since I abandoned that ages ago, I have no recollection beyond that I found the needed informantion in the datasheet/User manual.
You may also get some info from the LPC935 datasheet/user manual, that one seems to be the most completely documented.
