Microcontroller › 8051 › How to interface computer’s Serial Port (RS232) with 8051 microcontroller (AT89C51) Error.,, Help !! › Thanks Amrith for your
Thanks Amrith for your suggestions, but I had tried it earlier it didn’t work. I found out the solution for this problm i.e :
1. Switch OFF the MC kit , connect it to the PC with serial cable .
2. (I am using “Flash magic” software to burn/dump hex file). Run the Flash magic software and Press start button to start burning the hex file.
3.When the software asks for “Reset the Device into ISP mode” , just Switch ON the MC kit.
4. This will flash/re-program the Mc kit , and Mc will start to work again normally.
And 1 more thing is that I had made some adjustments in the Flash magic Soft i.e : in Options – Advanced Options- Misc- I had tick marked “Disable signature Checking” and “Erase all Flash using Pages” buttons. I un-marked them after my Mc started working properly.
