Problems installing MTD for 64 bit bus

Mon Dec 15 20:55:03 EST 2003

Greetings-

I am having problems getting up a JFFS2 file system with linux kernel
2.4.17 on a 8260 processor with 64 bit bus. I had success in bringing up a
similar board with 32 bit bus without any problem.  I went through the
mailing archive and as advised applied the latest
mtd-snapshot-20031208.tar.bz2 on my kernel. I found there were a few
compiling problems I could resolve some, but the zlib.h and some other
files were causing problems, which I was not able to resolve. So, I decided
to go to a relatively older mtd snapshot and used mtd-snapshot-20020731,
which has 64 bit support and fewer changes. I was able to compile and
configure, but I am having problems installing JFFS2 on MTD. Could you
please tell me where I could be going wrong..

thanks
Arun
