[U-Boot-Users] U-boot for MIPS - problem using latest gcc

[U-Boot-Users] U-boot for MIPS - problem using latest gcc

[Jerry Walden]

Hello:

I have three issues.  The exisiting distro uses the "mips-4KC-gcc", I am
using "mipsel-gnu-linux-gcc".  There are 2 command line options:

1) -mcpu=
2) -mabicall

For "-mcpu=" I substituted "-march=mips32" - is this correct?

For -mabicall - what should I substitute?


Also - I get an error building cpu/mips/start.s

On line 242 there is a label "memsetup" - the error is "cannot branch to
undefined symbol". Any ideas?

Thanks Much!

If this is a MIPS32 processor, yes.

Dunno. Does your compiler documentation mention this keyword?

Yes. The file board/<yourname>/memsetup.S is missing / incorrect.

I do not understand the response.  Are you saying that something is
wrong with my file layout?  Should I not be compiling this file?
Basically - how do I fix the problem?

Thanks

You got an error because "memsetup" was  undefined;  "memsetup"  gets
defined  in  board/<yourname>/memsetup.S  - so obviously this file is
missing or incorrect for your board configuration.

First - I downloaded u-boot v1.0

Then - I unzipped it.

Then - I changed CROSS_COMPILE to be the latest MIPS compiler

Then - I did a make dbau1x00_config

Then - I did a make all.

Memsetup.S is definitely in board/dbau1x00/

So - the file is not missing.

You said:

>missing or incorrect for your board configuration.

Since it is not missing - it must be "incorrect".  What would "incorrect
be"?

Thanks much

Indeed. And actually this is building fine:

	-> tar jxf /opt/tarballs/u-boot-1.0.0.tar.bz2 
	-> cd u-boot-1.0.0
	-> MAKEALL dbau1x00
	rm -f include/config.h include/config.mk
	Configuring for dbau1x00 board...

	net.c:492: warning: integer overflow in expression

	 112120    4760   17252  134132   20bf4 u-boot

Since all of your  steps  except  one  work  fine  here  I  can  only
speculate  that  the  problem  must be in the step where we do things
differently: I use a working compiler.

Seems your toolchain has some problems?

[U-Boot-Users] U-boot for MIPS - problem using latest gcc

[Jerry Walden]

My toolchain builds the latest mips kernel and the kernel runs
perfectly.

If you look in start.S - there is a branch to memsetup.  In start.S
there is NO definition of this symbol (i.e. as an external or
otherwise).  

The start.S file includes some files, none of which have any reference
to memsetup.  Does the toolchain in ELDK assume that any symbol which is
not defined as an extern, or is not defined in the file as a direct
label, must be external?  Makes no sense to me.
