P89V51Rx2/P89LV51Rx2 / Re: P89LV51RD2 ISP programming
August 02, 2007, 01:31:29 AM
I really appreciate everyone's help... Still, the old version of FlashMagic (I don't know which) worked fine. Question is: Where do I get an older version that works, without the timeout issue.. Or perhaps, one that automatically inquires about the device, requests a reset, responds with the error and automatically presses start for me?

Problem is, I recently tried to encourage some co workers in Asia to use FlashMagic, because it was so easy. Now I have to walk them through the whole tortured process, which really doesn't make sense to them. By the looks of the way my latest version works, a software change is all that's required to fix this!

I understand that, running at 6MHz, my processor has what, 800mS in which to respond? Why did the earlier software work fine? My computer HD crashed since I had programmed through ISP to this project board, and during reinstall I now have the latest FlashMagic version. How do I get the old version that actually worked?

P89V51Rx2/P89LV51Rx2 / P89LV51RD2 ISP programming
July 21, 2007, 12:25:53 AM
I have the newest version of FlashMagic (3.61.230), and to program the P89LV51RD2 I first have to:

1. Attempt to read the device signature.
2. The tool requests that the device be reset.
3. I reset the device.
4. The tool tells me that the operation failed.
5. I cancel the error message window

Then I can hit 'Start' and the device will begin programming immediately.

If I attempt to simply hit 'Start', withoput the above procedure, the tool will tell me that the 'operation failed (erasing device)', and any subsequent attempts to start programming will give me an hourglass on the app.

This was not the behavior of the earlier software, and I wonder what is wrong...
