I am working on ATMEGA 32 micro controller. I am using Code Vision AVR and parallel port programmer(Kanda System).
first time when i program the chip it is working fine. but if i try to reprogram the chip i am getting error message.
I have tried with 4 chips. but the result is same.
what could be the problem. Does all the chips were damaged or locked? how to know whether the chip is damaged or locked? Is there any way to solve my issue?
Please help me.
communication error, please check the following:
- the programmer power supply is on
-the avr chip is damaged.
the above errors occured when programming for the second time.all the connections and power supply are properly given. same thing has happened with all the 4 chips that i used.
programmed fuse bits for atmega 32 clock freq=8Mhz are
CKSEL0=0
CKSEL1=0
CKSEL3=0
SUT0=0
these fuse bits have not been changed while programming for the second time..
Hi Nandu,
Thanks for your suggession.
Now i have got new ISP programmer from Atmel (AVR ISP MKII).
i am getting the following error message when i connect AVR ISP to my target board "AVRISP MKII COULD NOT ENTER PROGRAMMING MODE"
I am getting this error for all my 4 ATMEGA chips(which are programmed with my old programmer). What could be the problem? Does all my 4 ATMEGA32's are damaged???
