Hi Scalerobotics,
Thanx for replying. I fixed that problem. Now I have a new problem. Its not at all detecting the PIC. I think there is no problem with the programmer because I can program an old PIC16F877A. But as soon as I replacing with a new PIC16F877A its not detecting with "CheckPIC" (a button on tiny bootloader). Its not even working with the file tinybld_16F876A_20MHz.HEX. Its saying...

Searching for PIC ...Not found,
ERROR!

Is there anything special I have to do for a new PIC16F877A which was never programmed. Thanx in advance.
