how to remove the flash magic error

[dagakshay]

many a times i get the query about flash magic that

“It alway shows an error-“check all  hardware connection or baud rate not matched”.

and on the other hand you have checked each and every hardware connection more than twice, your baud rate is 9600 and the com port u have selected is the same on which you have connected you burner…

 

then what is the error how to come out of it… 

am i right… 

here is the mistake what we generally do since we are not aware of it.. we never configure the hardware.. here i am writing the steps just go through them.. and try to burn you controller then…

step 1:

go to option->advance options

 

step 2:

just uncheck the option marked in red in the figure below… since you are using only two pins Tx and Rx of your

serial port to burn your controller…..

 

 

now burn your ic and let me know if you have any problem…
