problem in loading program to 89C51 microcontroller

[Shunno Hridoy]

I am using Atmel 89C51 microcontroller. My desired project is “How to create text animation on 16×2 LCD using 8051 microcontroller (AT89C51)”. I made a hex file using Keil UVision4. Now I’m trying to load program using Flash Magic software. My pc’s running operating system is windows 8.1 pro 64bit. My facing problem screenshot and my loder/burner picture add here. please give immediate solution. I installed Usb2.0 serial driver in my pc succesfully. My programmer/burner model no is STC 89C52RC.

go to tools then terminal…set lowest baud rate then in terminal window. keep pressing U from keyboard and then power on your 8051 board..

if in terminal window controller sends same character back to you then its bootloader is  ok of your board ..

now close terminal window then select your hex file and program.

Always try with lowest baud rate as possible.

TRY with O, & F key if U Not worked..

best luck…

I had already tried at the lowest baud rate 2400 in the flash magic but same error message come. my microcontroller is at89c51. but in flash magic i could not found the same model number of my desired microcontroller. So I selected their 89CV51RD2 in 80C51 section. Is it correct or not !!!!!!!!  please me the correct model no that i should select in flash magic for my 89c51 microcontroller……

when you pressed character from terminal window and restart your board..does that character echo back????

if yes then bootloader of your controller is ok… if not

remove serial cable from board &

then short pin 2 and 3 of your serial cable and try to send character from terminal if it echo back then your cable is ok…

 

if cable is fine and controllers bootloader seems to be damaged you need to change controller.

 

Best Luck…..

my dear friend,

flash magic software is to program NXP devices like P89V51RD2.

it can not program normal 89C51 from Atmel like AT89C51/52 AT89S52 etc

you have to buy atmel programmer or EEPROM programmer that works on ur win8 64 bit OS
