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...
