#165383 - Flash Magic problem |
I am using flash magic for programming 89v51rd2 devices for past few years.
But recently i have come acroos a problem. when I start flash magic a window comes up saying "reset the device into ISP mode now" as usual, but before resetting suddenly an error message saying "unable to read signature bytes, please try to connect at lower baud rate" appear on the screen. and then even after resetting it doesnot program the device. I changed my com port/cable/reinstalled latest flash magic software,tried with no. of devices. But the problem persists. does anyone came across such a problem anytime? How to overcome it? |
