Hello Sir/Madam
After reading some of the Post in the forum I found out using a multimeter that PIN 5 of serial cable has +10V with respect to pin 3 of serial cable so it may lead to a floating gnd problem in the ckt,and also the flash magic is unable to program the microcontroller its showing message box of reset option when i push start buttom but when i am pressing the reset buttom its not responding to it.
Even I have a shock sensation felling when i touch the gnd terminal of the ckt(After joining the gnd of serial cable to the 5V Ckt GND)
PLEASE help me to solve this problem.I am using a desktop PC.
Thanking You
