How to compiler the code(ERSKY9x)?
yagarto-bu-2.22_gcc-4.7.1-c-c++_nl-1.20.0_gdb-7.4.1_eabi_20120616 + Cygwin ?

Thanks

[bertrand35]

Right. Where is the problem?

Best check with Mike on that one....

Under open9x we add loads or compile time options. There may be some you need on ersky9x.

May be a different make program. I don't use cygwin. I already had WINAVR installed, so I used all the utilities, including make I believe, from there.

Hi Mike

I used Winavr but still can not compile.

I use the 4.6.2 version of arm-gcc.
Bertrand.

Side note: Mike on open9x I only use -Os on the stock board. For the other boards I use -O2

bertrand35:
where to download 4.6.2 version of arm-gcc? windows linux?

[gohsthb]

4.6.2 is on the yagarto sourceforge page
http://sourceforge.net/projects/yagarto ... /20111119/

thanks Gohst.

I used Winavr + 4.6.2 arm-gcc.

You need some options after the MAKE command.
First - specify the REVB board (REVB=1).
Second - specify use the generated stamp info (STAMP=1)
I also use include debugging code (DEBUG=1)
I also have an early version of the board I use for testing that only has a 3S2 (not 3S4) version of the processor (SAM3S2=1)

So you want:
make REVB=1 STAMP=1
or:
make REVB=1 STAMP=1 DEBUG=1

Mike there is an issue in the code with latest 4.7.1 and latest binutils.
have a look here:
http://old.nabble.com/-Bug-gas-13215--N ... 16436.html
and here:
http://code.google.com/p/open9x/source/detail?r=1153

As you can see in open9x we patched it.
Now it compiles without troubles even with 4.7.1

[MikeB]

Thanks, I'm still using the 4.6.0 I downloaded at the start of the ersky9x project.

Mike.

[Romolo]

Yes we still use 4.6.2 on server, but yesterday I upgraded compiler chain on my desktop and I discovered this error too, the bad thing is that is assembled the same way on 4.6.2 only the warning is missing.
The bad news is that, accordingly to atmel datasheet, it brings to unpredictable result, the good one is: that code doesn't seem used.
But as the fix is very simple it seems worth to be patched.

BTW we have no flash usage issue on arm but 4.7.1 spares 350 bytes

[MikeB]

I might upgrade when I have some time then. I have put the fix in ersky9x anyway.

Mike.

[neolu]

The code is compiled ok.

Start study the code.

Thanks
