File I/O error - ahma...@yahoo.com - May 29 8:14:11 2008



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
