Where exactly did it hang? What was the command you used, and what was the exact output?

I tried it now, and it got stuck indeed:

It's not a a script, but a binary, so you are limited to  tools  like
strace, ltrace etc.

In my case I see this:

# strace -p 21197
Process 21197 attached - interrupt to quit
futex(0x96fe17c, FUTEX_WAIT_PRIVATE, 1, NULL

i. e. it's hanging in a futex call. [Futextes have often before  been
a major PITA].

A quick workaround seems to be to build the installer on  the  native
(Fedora  9) system; download the source and the Makefile from the git
repository:

http://git.denx.de/?p=eldk/build.git;a=tree;f=install;h=5f1a9bb9ca5757f4efbca7ff4f48bf869a2ef949;hb=90ed3ca5e1163d771badf1c26f76e95d95e13990

and run:

$ make TARGET_ARCH=ppc

Then use this "install" binary to replace 

Then reboot, and then try again.  Note  that  the  reboot  is  really
necessary,  or  at least I do not know of any other way to get rid of
the stuck futexes.


BTW: ELDK related questions are better posted on the ELDK mailing
list, see http://lists.denx.de/mailman/listinfo/eldk

Best regards,
