[microblaze-uclinux] fgetc() blocks, problem solved

[Lars <lpn1328@xxxxxxxx>]

After getting remote debugging working I solved the
problem. The application program had a fuction called
'read' that was called from inside the fgetc code
instead of the uCLinux read(from file). I renamed the
application 'read' function and now file io works
again!

Thank you for remote debugging!
