ppc-82xx_objcopy hangs

ppc-82xx_objcopy hangs

[Marc Leeman]

I am in the process of porting our MPC8245 system to the MVista 3.1
(from 2.1). Just like with the kernel, this requires major code cleanup
in the kernel (sources I 'inherited' when starting :( ).

After cleaning the kernel sources and patching the 3.1 kernel, I want to
cleanup ppcboot and move to u-boot. I intend to do this in a 2-step
process.

1. compile a clean patch from ppcboot-2.0.0 to ppcboot-2.0.0-custom
2. port the patch to u-boot

I have the following problem:

1. ppcboot-2.0.0 compiles cleanly on the 3.1 env. for a board (a README
config).
2. when compiling the ppcboot-2.0.0-custom sources (with support for our
system), the compilation succeeds, but
ppc_82xx-objcopy --gap-fill=0xff -O srec ppcboot ppcboot.srec
gets stuck.

Idem for a system where I only brought in a couple of changes from the
old sources. Any ideas as to what code might cause this problem?

Seems you version of objcopy is broken. Try using the native objcopy,
or the cross objcopy from the ELDK.

Best regards,

baud rate question

[Brian Hawley]

Forgive the obvious newbie question, but we've tried everything, reviewed
the readme's, etc.

We are using the linux-2.5-ocp tree from bk.

We are using u-boot 1.0.0.

We set u-boot to 38400 in the config.  linux wants to be 9600 by
default.  So, we realize
that we can't see the kernel boot up.

We've tried changing u-boot back to 9600, but haven't been able to.

Is there a way to tell linux to come up at a different baud rate?  We've
tried the earlyserialpk option, and the console options...but no luck.

Thanks for any assistance.

Wolfgang,

It seems you were right, your version of the GCC compiler does not
produce this problem [1], while the MVista tools do [2]. I guess it's
time to issue a bug report.
