Hey Adam,
Yes I can confirm that I was a able to trace the code from fpage_map() to map()
but I see zero addresses there - i.e. When I check the receiver and sender
addresses and size everything is zero. This was despite it being correct until
the handle_sigma0_request() function in

Yes, there are produced more than thousand identical entries in less

'26' is the id of the thread that is waiting for '1b'.

Hi,
thanks again for your quick reply!

Hi,
thanks, I've used addr2line and found out that it was the head of
thread_func (l. 27 in examples/libedft-example/main.c).
So it seems that the stack I'm using for passing arguments to the thread
function is the problem. As I am creating a dynamic number of threads,
it does not make sense for

Dear all,
I would like to extract the minimal subset of uclibc required by bootstrap,
sigma and their dependencies only. My idea is to have these modules use the
smaller libc while retain the usual uclibc build for the other packages.
I intend to go about this by copying uclibc (say into
Update: turns out it is not very simple to compile just bootstrap against a
smaller library because the l4/mk/modes.inc file defaults to the uclibc library
for compiling the files which is used for all packages. Any ideas how I can
change this only for some packages?
Thanks.

Hey Markus,
I am using a version from April 2011 but even that version contains a lot of
things that bootstrap and sigma0 do not need. :) Did you mean more recent than
that?
best,
ramya
p.s. my board requires that I run an older version of the kernel - so the pain.
Hi,
as Marcus already pointed out, newer versions of L4Re actually contain a
package called uclibc_minimal that serves exactly this purpose. Even if
you are using an older snapshot, chances are that backporting this
package (and adapting l4/mk) might be easier than stripping things down
