Accessing PRAM on SCC ( MPC852T )

Hi,

I need some insight into the u-boot cpu/mpc8xx/scc.c driver. I am able to use the SCC4 with these settings but to use the SCC3 I have got to comment these line. Any leading as to where I can look for an explanation most welcome.

Thanks in advance.

Warm Regards,
Raghu

Good morning (o;

Didn't find any ELDK related mailing list so I am asking here (o;

Tried to install on SuSE 8.2 and it stops at the beginning:

dell:/home/klingler/ppc/eldk-ppc-linux-x86 # ./install -d /usr/eldk ppc_82xx

Do you really want to install into /usr/eldk directory[y/n]?: y

Dear Rick,

This is a known problem which will be fixed in ELDK-3.0 (due to be out soon).

You have two options:

1) Install on an older SuSE or on a RedHat system and copy the files
2) download the file ftp://ftp.denx.de/pub/tmp/ELDK-update-2.2.0.tar.bz2 Then change into the source tree with the ELDK files and perform the following operations:

        bash$ rm RPMS/rpm-4.0.3-1.03b_2.i386.rpm \
                RPMS/rpm-build-4.0.3-1.03b_2.i386.rpm \
                RPMS/rpm-devel-4.0.3-1.03b_2.i386.rpm \
                tools/usr/lib/rpm/rpmpopt-4.0.3
        bash$ tar jxf /tmp/ELDK-update-2.2.0.tar.bz2

Then build the ISO image as documented, and try again.

Morning again...

Anyone seen Bernhard Kuhn's Coldfire patch lately?

Otherwise I'll restart again with m68k/CF support for u-boot-1.0.0
