[U-Boot-Users] printf and MPC8540

[Armand Ciejak]

When compiling u-boot 1.1.2 for a MPC8540 board. I have a crash in the 
printf function. After looking at the assembler code generated I found 
the "stswi" instruction which is not supported by the e500 core. The 
config file I use is based on the MPC8540ADS config file which has the 
following defines:
/* High Level Configuration Options */
#define CONFIG_BOOKE         1    /* BOOKE */
#define CONFIG_E500          1    /* BOOKE e500 family */
#define CONFIG_MPC85xx       1    /* MPC8540/MPC8560 */
#define CONFIG_MPC8540       1    /* MPC8540 specific */
#define CONFIG_MPC8540ADS    1    /* MPC8540ADS board specific */

I use ELDK3.1 and CROSS_COMPILE = ppc_6xx-

What should I do ?

Use a recent version of U-Boot. It is nearly always a bad idea to use
old versions for current work.

Well, according to the U-Boot page at SF, 1.1.2 is the most recent
official version.
What am I missing?

It's the latest officially _released_ version.

The latest version is top-of-tree in CVS.

I know that.  But I was referring to this:

Normally, it is a bad idea to use the latest CVS source for
important work.  Instead, you normally use the latest official
release.  Is this different for U-Boot?

For any _current_ work you really better use current sources,  i.  e.
top  of tree. So far (*), U-Boot gets release only very infrequently.
If you stick with a "release" version you will have serious  problems
at the time when you try to get your patches merged into the official
source tree.

So if you start any new project I really recommend not only to  start
with top of tree, but also to update your sources regularly.


(*) This will hopefully change Really Soon Now.

The top of CVS?

Also make sure that the -mno-string option is in your build.

This has been default option in cpu/mpc85xx/config.mk since March 15.

Hello, Wolfgang, Jon!

>>Also make sure that the -mno-string option is in your build.

Oh, good to know. Can some of you please explain more in detail,
when this is needed? I guess, gcc 3.4.x+, binutils 2.15+, right?
I ran into some compiling problems while using some modified
(and non published stuff I need) u-boot-2004-08-18-2000
which shows up as 1.1.2 also :-(

Don't ask me why it wasn't published...
I'll ask our vendor, first.

Great :-|
