File I/O error

Hi all
I have written a C source code for C55x simulator in which I have
used the "fopen" function for reading the input samples from a file. But when my program counter reaches to fopen execution the following error is displayed several times and the program exits:
Invalid CIO command (0).

I deleted the "fopen" and "fprint" and other file related functions
and use a constant array as input data (instead of file context). Then I ran the program again and the following error message happened during execution of my program:
Trouble running Target CPU: WARNING: PAGE BOUNDARY CROSSING DETECTED
AT PROGRAM COUNTER 0x12ee3
the 0x12ee3 address is part of the _printfi(text) code.

my .CMD and .map files are as follow:

PAGE 0: /* ---- Unified Program/Data Address Space ---- */
PMEM (RWIX) : origin = 0x000100, length = 0x01ff00 /* 128Kb page
of RAM */
PMEM2 (RWIX) : origin = 0x020100, length = 0x01ff00
PMEM3 (RWIX) : origin = 0x040100, length = 0x01ff00
PMEM4 (RWIX) : origin = 0x060100, length = 0x01ff00

PREM2, PREM3, PREM4 are not on PAGE0. they are on PAGE1, PAGE2, PAGE3.
try by removing PAGE0
