Hi Cristoph,
have you tried to increase the application stack during compiling phase.
If you use a gcc-like compiler, you should use the flag -Wl,-elf2flt="-s
8192", where 8192 stands for 8KB stack.
In my case, it worked.
Bye

Hello all,
working on an application for an ARM target (no MMU!) with uClinux I ran
into a strange problem. When I try to allocate 4MB of RAM the allocation
fails. If I then try to allocate 4MB minus 4k (one page) it works. But
then no other application can allocate memory until the first
application either frees its memory again or gets killed by the kernel
to make more RAM available. /proc/meminfo shows that there are ~10MB of
free RAM.
Meanwhile I checked the value of MAX_ORDER which is set to 13.
So any ideas out there?
Thanks and Regards,
Christoph
