I have an EZM MK-328 in the case. It looks like this one:
http://i.ebayimg.com/images/g/ZOUAAOSwcBhWZP31/s-l500.jpgIt originally had 1.12k firmware. I just tried to flash the latest K firmware and am having trouble. I have successfully flashed firmware on two different, older testers, so I know the procedure.
Using a USBASP, I flashed the firmware HEX file. I got a verification error. Now, when I try to re-flash or erase, I get the following:
avrdude: error: program enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
When I use the -F option, I get this:
avrdude: error: program enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x4c0000
avrdude: Expected signature for ATmega328P is 1E 95 0F
As I said, I have flashed other testers before with no trouble. What happened this time? How can I fix it?
