I wrote a programe in keil and converted in .hex file after that when i use software flash magic to burn the programe it show RESET IN ISP MODE..how to remove this error and burn programe in microcontroller….alternatively any other software to burn programe in controller with using convertor.

 

Please help me.

First check if you need to install the USB cable driver on your laptop. Did your USB to serial converter contain any CDs containing the driver? if not check the manual (if it was with it) and see if there’s a website from which you can download the driver from. (Nowadays some manufacturers prefer to give links to drivers instead of providing a CD/DVD with drivers). To see if you require any drivers open the Device manager (Right click on my Computer -> Manage and the Snap-in should display and click on Device Manager) then connect your converter and 8051 and see if anything from the list changes. If there’s an unknown device then you need to install a driver for it.

 

Try using ATMEL FLIP, it is a good program. Remember to hold RESET and press PSEN and continue on holding RESET and release RESET after a few seconds before clicking to flash the 8051 EPROM.

 

Hope this helps.

Hey Clinton

I installed USB cable driver on my laptop as USB to serial converter contain  CD containing the driver .I saw in Device  manager there is only one change i can see Ports (com&LPT) and after expanding it show Prolific USB -To -Serial Comm Port(COM 28)..

and at device manager i can’t get any Unkown Device.So i think there is not problem with any Driver to be install.

 

Need help!!!
