Patch to compile on Linux #55

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The attached patch contains a Makefile to compile the firmware on Linux.

I had to fix some #include's because the Linux preprocessor is case sensitive.

Also please note that your source files have mixed Windows and Unix line 
endings (CRLF vs LF). I left that as is.

Oops... forgot to fix UART.c

applied and commited. Thanks! Please also consider joining us in the forum, 
it's a lot more active there :)

How was the Linux compile? Do you like MPLABx?

Thanks for the quick reply.

There was a problem with your commit: eetext.s should have been renamed to 
eetext.S (capital S).
Apparently there's a bug in SVN because renamed files don't show up in the 
patch.

Also compiling the BPv4 variant does not currently work. I'll have to figure 
out where to get the USB header files...

Hi Stephan,

I've fixed eetext.s into eetext.S
Your makefile works against the current SVN.
But there is also a new Makefile made automatically from my MPLABX conversion, 
in busPirate.X/busPirate which works too.
What I don't understand is the difference in size between your .hex and mine:
main.hex: 154804
busPirate.production.hex: 205080

Hi,
Thanks for fixing my Makefile! As for the file size, I'm using "-Os" to 
optimize for size. It's strange that the could should be 25% smaller, but I 
checked that all modules are included.

For BP_MAIN I get a main.hex of 176792 bytes
For BP_ADDONS it's 154804 bytes

If I use "-Os" in MPLABX, I get a hex size of 147992 and 169980, respectively

Hum there is definitively something to explore here...
I could make a firmware containing both MAIN & ADDONS module (except I2C_HW for 
which compil fails ATM) and the device seems working fine!! (I tried self-test 
& UART sniffing)

I tried to compare your Makefile with MPLABX one and I see the following diffs:

Yours:
 space optimization: -Os
 ee.c & eetext.S

MPLABX's:
 via elf format: -omf=elf
 def intern symbols, probably not needed:
 -Wa,--defsym=__MPLAB_BUILD=1
 -Wl,--defsym=__MPLAB_BUILD=1

ee?? is it a kind of easter egg?? And people say the firmware is full, pfff :-)
So I think all diffs you saw come from the optimization flag and this ee 
stuff...

What do you suggest for both Makefiles?
Can we add properly the -Os flag in the IDE so we can keep the sole MPLABX 
Makefile?
It's a bit less neat than your but, well, it's there anyway and managed by the 
IDE...

Would it be possible to move this to the development forum:
http://dangerousprototypes.com/forum/index.php?board=28.0

Can I also give you SVN access so you can commit these patches as needed?

Done, see

Makefile discussion
