I want to read 5000 date from the file using the i/o function on the dsp 28335 in ccs3.3.but when the dsp reads the 4134th date, then an error appears .the main source code and the error is as follows:
The main source code :
fid = fopen("ztq.txt","r-"); ////open the file
setvbuf(fid,Sting,_IOFBF, sizeof(Sting)); ////set the buffer
while(i!=5000) ////read the file
{
fscanf(fid,"%d",&ko);
ab[i++]=ko;
}
fclose(fid);
the error:
The CIO command cmd:(255) in the CIO buffer at address (0xf000) was not recognize d. Please check the device and program memory maps.
The CMD file refered by the error:
MEMORY
{
PAGE 0 :
PAGE 1 :
RAML7 : origin = 0x00F000, length = 0x001000
}
SECTIONS
{
.cio : > RAML7, PAGE = 1
}
The device and program memory maps refered by the error:.
SECTION ALLOCATION MAP{
.cio 1 0000f000 00000120 UNINITIALIZED
0000f000 00000120 rts2800_fpu32.lib : ankmsg.obj (.cio)
}
My question:
Why does it generates an error? What’s more, why can it read 4134 date and why can’t the other date be read?
Thank you for your answer.
