Solution to PCREL error for avr25/ATTiny84/ATTiny85/ATTiny88.

Download WinAVR here, extract the files (it's a zip file)

http://sourceforge.net/projects/winavr/files/latest/download?source=files

a) Find the "bin" folder in the extracted files.

b) Find a similar looking folder in your Arduino installation.

Copy all files from (a) to (b).

[Tom Carpenter]

have you restarted the IDE?

Double check you put the ld file in this folder:
"<arduino directory>\hardware\tools\avr\avr\bin"

Did you extract the ZIP file?

Did you definitely get the Windows version (not the Mac version by accident)?



This fix definitely applies to your problem, and should work.



@fungus, you don't need the whole folder, just the ld file.

@fungus, you don't need the whole folder, just the ld file.

True, but why not have the latest compiler, etc., as well?

The only BIN folder I find in the Arduino-1.0.3 dir is in the java folder. is that it?

No. You want a folder with the same files in it as winavr's 'bin'.

Mine is: ./arduino-1.0.1/hardware/tools/avr/bin

Yep, found it. I was looking in the wrong place. It looks like it works now. Thanks everyone's help.

[Shimon]

Worked for me.
Thank you very much.

[gingerwig]

Cheers Tom. A nice quick fix!

[septic]

Thank you, thank you, thank you, Tom. The Id patch worked perfectly with Arduino 1.0.4 on Mac os X 10.6.8. Now I can program my attiny85!

Dear Tom

I'm having the same problems at everybody in this thread but your fix unfortunately hasn't helped. I'm using Arduino Uno and ATtiny85. Here's my error:

Here's what I've done to try to fix it:

1. Followed every step in http://arduino.cc/forum/index.php/topic,60649.msg437771.html#msg437771 (I didn't have WinAVR previously so didn't have to replace anything, there was no tools folder)
2. Downloaded the patch and replaced the ld.exe file in the hardware/tools/avr/avr/bin folder with the one from the patch zip

I definitely got the Windows version, not the Mac one.
I have restarted the IDE.



Let me know if I should post anything else, like my code (really long and essentially irrelevant to this problem if I understand correctly) or boards.txt. Thanks a bunch!

[icegooner]

Does anybody have any tips for me? I'm making a birthday present for my little nephew for his party tomorrow and I'll be in quite a pickle if I can't get this sorted. Any help would be greatly appreciated!

If you don't have WinAVR installed, how could you follow every step?

[Coding Badly]

Navigate to this directory...
[font=Courier New]C:\Program Files (x86)\Arduino\hardware\tools\avr\avr\bin\[/font]

Is there a file named[font=Courier New] ld.exe [/font]in that directory?

Is the file dated[font=Courier New] 12/04/2008 [/font]or[font=Courier New] 3/14/2009[/font]?

[icegooner]

I just set up Arduino IDE and did everything again according to instructions on a new computer (and there was stuff different between this and the one from before, like when I installed Arduino IDE on the previous one there was no tools directory, but now there was). And the ld.exe file was dated 03/14/2009.

Anyway, I've done everything and things are looking up, but there still one error (related to ld.exe).

Code: [Select]

e:/arduino in/arduino/hardware/tools/avr/bin/../lib/gcc/avr/4.3.2/../../../../avr/bin/ld.exe: infmirror.cpp.elf section .text will not fit in region text
e:/arduino in/arduino/hardware/tools/avr/bin/../lib/gcc/avr/4.3.2/../../../../avr/bin/ld.exe: region text overflowed by 4440 bytes

I've replaced the old ld.exe (dated 12/04/2008) with the one from the patch (dated 3/14/2009) but now this is the only error I get. Any ideas?

EDIT: I've just discovered that now I'm just being dumb and I've exceded the ATtiny capacity... So I'm all good now, I'll just have to try to shorten the code before the big birthday tomorrow. Thanks a bunch Coding Badly!

You are welcome.  I'm glad you are back on track.
