avrdude error opening test_leds.hex: No such file or directo

The USBtinyISP is talking to the chip but i get this message.

avrdude done.  Thank you.

Im using a Macbook and don't know where to put the test file, from this tutorial.
http://ladyada.net/learn/avr/avrdude.html.
I saved it in my documents folder. But its not really a file. Its a web page. Zeros, ones, and letters.

Also, I can't get the Arduino boot loader to burn to the chip using your USBtinyISP.
Please help.

But its not really a file. Its a web page. Zeros, ones, and letters.

You can't directly load a web page. Could you give us more info like how you created the hex file, what you are trying to do and what command you use to launch avrdude? Also what are you trying to program and how is it connected?

[rc_flyer]

My goal is to burn an Arduino sketch to the chip for a project. But first need the boot loader on the chip.
Here is what I have. A MacBookAir. The chip is an ATtiny861A
The red wires are all 5v, and white are data, ground, other. The crystal and caps are Adafruit part number 2215, 16mhz, 20pf.



At http://ladyada.net/learn/avr/avrdude.html
the AVRDude tutorial, in the "putting it together" section, about halfway down the page it says to.....

Download the test_leds.hex file and place it in C:\ (Windows) or your home directory (Mac)
When I click the "pink" link it opens this....

So I copied it to text edit in plain text format and saved it as 'test_leds.hex' in my documents folder. I don't know what
a mac 'home directory' is.

Am I getting the wrong hex file, or putting it in the wrong place, or format?

The chip is an ATtiny861A

and what bootloader are you trying to load on this chip? Also what is the command you are sending to avrdude to try the load?

[rc_flyer]

I am trying to burn an Arduino sketch to it.

I haven't tried to load anything yet with avrdude.
I'm still trying to get the USBtinyISP to work.

I have been trying to burn a chip, nights and weekends for 2 months with no success.
And a support member from element14 said I need a USBtinyISP.
So.............here we are. lol
I almost wish I had not started this, but now, it is no longer an Arduino project.
It is all out war with this little Tiny !!

[Franklin97355]

You can use the USBtinyISP to burn code to your chip but it is not an arduino so you need to write code that runs on a ATtiny861A

I'm still trying to get the USBtinyISP to work.

What is not working? All it does is send data to the chip usually using avrdude to configure and send the data to the USBtinyISP.

[rc_flyer]

I suspect it is working, except for the error opening test_leds.hex.
This file is probably in the wrong place.

But, if I burn the Arduino boot loader to the tiny, can't I then load a sketch on it and it will run
as if it were an Arduino?

[rc_flyer]

I just thought of something............
If I get the Arduino boot loader on the chip, then burn my Neopixel sketch to it,
will the sketch run, because the Neopixel library is on my Mac and not plugged in with the usb cord?

[Franklin97355]

1.) The Tiny is not an Arduino and has different registers and memory maps.
2.) The sketch upload will load everything it needs to function including any libraries included. These libraries need to be written for the Tiny or be generic enough not to call any ATMega 328 specific functions.

Thanks Franklin.
I am still getting...

avrdude: error opening blink.hex: No such file or directory

Where am I supposed to save this file so avrdude can find it?

Here is the code entered in avrdude...

Code: Select all

avr-gcc -mmcu=attiny861 -Wall -Os -o blink.elf blink.c

avr-objcopy -j .text -j .data -O ihex blink.elf blink.hex

avrdude -p t861 -c usbtiny -e -U flash:w:blink.hex

I'm using a macbook.
I put it on the desktop, and in the documents folder.
Neither place works.

Please help.

[adafruit_support_rick]

blink.hex or test_leds.hex needs to go in the same directory as avrdude. Either that, you you must specify the full path to the .hex file in your avrdude command line.

For instance, if test_leds is in your Documents folder, you would enter

avrdude -c usbtiny -p t861 -U flash:w:/Documents/test_leds.hex

[rc_flyer]

I give up!

[adafruit_support_rick]

Did you try my suggestion? What was the result? What is the folder path to your .hex file?

[rc_flyer]

I tried your suggestion with no change.
I can't bring myself to give up.
But I'm so confused now........I not sure what I'm supposed to be doing.
So I'll tell you everything I'm doing.

Installed Crosspack for AVR
Attiny861a on bread board
Soldered USBtinyISP and used jumpers in place of r4 and r7.
Usbtinyisp with jumper in place for power to tiny861a on bread board.
USBtinyISP jumpers as follows.......ribbon pin 1 (by red wire and arrow) to miso on 861a, pin 2 to vcc and avcc, pin 3 to sck, pin 4 to mosi,
pin 5 to reset, pin 6 to gnd and agnd.

Plug in USBtinyISP via usb cable to macbook. Green light comes on.
Also the led on bread board from vcc to gnd comes on.

Then from http://www.micahcarrick.com/tutorials/a ... r-tutorial
I open TextWrangler.app, copy and paste the following, then save it in documents as blink.c.

Code: Select all

#define F_CPU 1000000UL

#include <avr/io.h>
#include <util/delay.h>

int
main (void)
{
    DDRB |= _BV(DDB0); 
    
    while(1) 
    {
        PORTB ^= _BV(PB6);
        _delay_ms(500);
    }
}

Then open Terminal.app in Utilities and type avrdude
Then copy/paste the following......

[img]avr-gcc -mmcu=attiny861 -Wall -Os -o blink.elf blink.c
avr-objcopy -j .text -j .data -O ihex blink.elf blink.hex
avrdude -p t861 -c usbtiny -e -U flash:w:Documents/blink.c[/img]

This is what shows up.

Then I hit Enter, in Terminal and get this.
