I am using Dynamic C 10.60 and set all the options as shown in screenshot, but still i am getting error pop-up as “'while sending pilot BIOS: target communication error”.

Please help me.

  1. Unplug the USB to RS-232 converter cable from the PC or laptop USB port.
  2. Download FTDI’s driver installer program at http://www.ftdichip.com/Drivers/CDM/CDM20828_Setup.exe.
  3. Run the CDM20828_Setup.exe (or later) installer program that you just downloaded. Remember to exit the installer when it is done.
  4. Plug the USB to RS-232 converter cable back into the PC or laptop USB port.
  5. Now compile and run the program.
