[microblaze-uclinux] fgetc() blocks

[Lars <lpn1328@xxxxxxxx>]

Hello list!

I porting a big (?) application (binary about 500kB)
to microblaze-uclinux. I try to read a text file from
ram disk. Writing the file works OK and I can verify
that the file exists on the disk by using "cat".

When I read characters from the same file the fopen
statement works OK but the fgetc() call just blocks
forever. The program can be interrupted with ctrl-c so
the system has not crashed.

A small 10-line test app built with the same tool
chain both reads and writes.

Can the size of the binary have any impact on file io?
I have also check that there is plenty of RAM left
when the prgoram is running.

Board is Suzaku S-030 with
uClinux-dist-20051110-suzaku3 and
microblaze-elf-tools-20060213
