Mega2560 as ISP for ATTINY45

system · February 25, 2012, 9:19pm

Hi guys,

I'm using the instructions found here to program an ATTINY45 using the Arduino as an ISP:

http://hlt.media.mit.edu/?p=1695

I'm using Arduino 1.0, a MEGA2560 with ARDUINOISP installed, and the ATTiny core found here: Google Code Archive - Long-term storage for Google Code Project Hosting..

Here is a picture of my setup:

Ok, so I modified the Blink sketch to use pin 0 as in the instructions, selected the output board type, and hit "Upload". Here is what happens (I've enabled verbose output in the preferences so I can see exactly what AVRDude is complaining about:)

Binary sketch size: 714 bytes (of a 4096 byte maximum)

Not sure what's wrong. It definitely seems to be communicating with the firmware, and it even seems to be sending stuff to the chip, but it just messes up halfway through.

Some help would be appreciated.

Cheers,

R

Not sure what's wrong.

I am. Buggy ArduinoISP sketch. Your (not mutually exclusive) choices are...

• Downgrade to Arduino 0023
• Change the baud rate to 9600 (modify the sketch and boards.txt file)
• Wait for your newly purchased programmer to arrive... Pololu USB AVR Programmer
• Send me a Personal Message with your email address and I'll reply with a version that works

system · February 26, 2012, 3:49pm

Ok, an update.

Tried your TinyISP sketch; no difference.

Tried modifying your sketch to use a 9600 baud rate, no difference.

Tried Arduino 028 and also 022, no difference. Modified those to use a 9600 rate, no difference. (In all three instances I had to change the baud rate in programmers.txt, not boards.txt).

Still stops at:

avrdude: Send: P [50] [20]
avrdude: ser_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding

in all cases.

So, I connected the diagnostic LEDs to the arduino. Neither of the other two LEDs ever light up except when first powering the arduino. The heartbeat one blinks until the upload fails, at which point it just stops blinking.

Seems as though the firmware is actually freezing up there.

Not entirely sure why. Trying to do some debugging now. What should the firmware be doing when the host sends P [50] [20]?

Cheers.

How are you disabling auto-reset?

system · February 26, 2012, 9:31pm

I tried two ways - firstly a 10uF capacitor from Reset to Ground, and when that didn't work I cut the removable track on the arduino and installed a jumper instead. Same result both cases. With the jumper installed there is no communication at all, so I don't think it's that.

Coding_Badly · February 27, 2012, 1:52am

Tried your TinyISP sketch; no difference.

The verbose output was identical?

A workaround

avrdude done. Thank you.

The undescored line is the key

Step 2 : Copy and paste the (underscored) line in a terminal, change 19200 for 9600 as suggested previously, and run.

That's all.
Please note : Both steps need to be done each time the code is changed, as the temp folders will change for each compile
