not able to reflash P89LPC9408

Syed Moulana

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

    A LPC "out of the can" is already in ISP mode and thus does not have any requirement that your 'kick the chip into ISP' works.

    You can, of course, fix your 'kick the chip into ISP' stuff, I abandoned that method long ago.

    I bypass all that by using NoTouch (and "the backdoor") both can be found at the FM site.

    Note: I only wrote the ones for the P89C51Rx2, the ones for the LPCs are provided by others. HOWEVER, I documented fully, so I suggest that you read the P89C stuff and then use the LPC routines.

    www.flashmagictool.com/.../touchless935.pdf - Can the code written in this FM web page used for flashing P89LPC9408 also?

    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.
