sir , What can be the probable reason for the board not being reset for dowloading the hex file onto the chip?
sir i have checked the voltage levels at every pin , they are ok. the WSD configuration is: crystal: 11.0592 kHz; baud rate set at 9600 COM1 has been selected for serial port transmission.
how can we know without you telling us what it is that you are attempting to do?
This world have seen a huge number of boards containing 8051 chips from a large number of different manufacturers. They do not work identically, which makes it important to know what board you have, and what processor the board is using.
