hi,

--first thing :u try to allocate 2048 of unsigned char which is equal to 2 mb, i think it's to much ! regardless your ram size ?

--seconde thing : to know that malloc() succeded u must do a test like :

if (p =! null) then ...

so i advice u to reduce the allocation size (something like 512 bytes). http://forum.niosforum.com/work2/style_emoticons/<#emo_dir#>/rolleyes.gif

best regards.

Well I sure hope 2K bytes isn&#39;t 2 MB, I believe that would be 2 KB. Regardless, no matter what amount I try and malloc() uClinux reboots. Note that when I "inline" the code into a single .c file, everything works just fine, which leads me to believe that this is a linker problem of some sort.

Also, I am aware that I should be checking the value of the returned pointer from malloc(), but in the second case (test_malloc.c and foo.c), I never even get that far, my board resets (seg faults?) right when the call to foo() is made.
