Hi

After pulling the recent git merges from stefan I get the following error:

ppc_4xx-gcc -D__ASSEMBLY__ -g -Os -fPIC -ffixed-r14 -meabi

I am using ppc_4xx-gcc --version
ppc_4xx-gcc (GCC) 4.0.0 (DENX ELDK 4.1 4.0.0)

Any hints would be appreciated.

Best regards

Hmmm. CONFIG_440 is set _and_ cpu=405. This is the source of the problem.

Is this a PPC405 based board or a PPC440 based board? Please include your board config file and I'll take a look at it.

As you may have noticed all 4xx boards (405 & 440) compile clean with ELDK4.0.

Viele Gr??e,
Stefan

Hi Niklaus,

Do you see any complaints about 'sed' not found? One thing that might be going wrong is while checking for the 440 vs. 405.

The board config file is found (using sed...) to decide on the variant -- see cpu/ppc4xx/config.mk. When the tool is not available the config.mk would default to chosing 405 and likely lead to such problems.

kind regards,
Rafal
