I'm trying to use flash magic to program my p89c51rc2ba.
It is able to read from the device and erase the device, but after it try to program a few blocks it fails and says there is a communication error. Then I am unable to read anything from the device.
But if I wait a few minutes I am able to once again read from the device, and have a chance to reset the boot vector.
I've used WINISP in the lab to program the device, so I know the chip is not bad.
What is going on here? Why is Flash Magic failing. How can I fix it?
And why does Flash Magic change the boot vector everytime it tries to program?
Also where can I download WINISP? I would like to try in on my home computer to rule out any problems with my com port.
Thanks
