Hello,
I have a serial single sided Arduino with an Atmega8-16PU. It does not work anymore and I hope some of you might have some suggestions.
My normal routine was to upload the bootloader with the parallel programmer and the code with the serial port.
A few days ago the bootloader upload stopped working. The serial sketch upload kept working fine for the chips with the bootloader installed.
I got the following error:
avrdude: AVR device not responding
avrdude: initialization failed, rc=-1
avrdude: Yikes! Invalid device signature.
avrdude: Expected signature for ATMEGA8 is 1E 93 07
avrdude: AVR device not responding
***failed;
avrdude: verification error, first mismatch at byte 0x0000
0xca != 0xff
avrdude: verification error; content mismatch
The only thing that I did different from the usual bootloader uploads was having an online radio open. .pls file.
I mention this because I know how sensitive Arduino can be to software like antivirus and disk emulators.
If I burn the bootloader without connecting anything to the Arduino I get the same error so It's like my Arduino board does not even exist to the IDE.
If I connect the parallel programmer to the Arduino and power it, the LED 13 is always on.
Now the serial sketch upload has stopped working for the micro-controllers with bootloaders. Now the RX LED blinks 3 times when I click on the upload button and blinks one more time after a few seconds.
When I upload a sketch I get this message:
avrdude: stk500_getsync(): not in sync: resp=0xf8
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0xff
I've tried a lot of the usual things that worked when I had similar problems but this time it seems that it's something else.
Are there any ways to upload the Arduino sketch besides the IDE? I searched with Google but I could not find another software package. I would like to upload the sketch with the parallel programmer.
I had these kind of problems before and after a few days of troubleshooting I get the Arduino to work. Unfortunately for me this time I need to upload a sketch on some Atmegas and I don't have this much time.
