Specification EDK version:8.2i FPGA Board: Virtex II Pro Compiler : mb-g++
I'm tring to create a file stream using ifstream instr("ba1.bits") or ifstream instr("a:\\ba1.bits") to create a file stream from CF card.
In addition I've added #include which is necessary to ensure that microblaze compiler recognizes the the c++ sections of code.
I've amended the file ....\EDK\sw\lib\sw_services\xilfatfs_v1_00_a \src\include\sysace_stdio.h uncommenting the following lines
#define SYSACE_FILE FILE // typedef void FILE;
#define fopen sysace_fopen #define fclose sysace_fclose #define fread sysace_fread #define fwrite sysace_fwrite
File cannot be read...
Alternatively I tried using sysace_fopen directly -> char array ->
streambuf
streambuf * pbuf;
void myrun(void * mybuf) { sysace_fread( (void *) mybuf, 1, 1, outfile); // pbuf->sputn (charbuffin,sizeof(charbuffin)-1); }
Int main (){ void *mainbuf;
if ((outfile = sysace_fopen("file.txt", "r")) == NULL) { xil_printf("Couldn't open the file\r\n"); } else{
for (int i=0;isputc( (char *) mainbuf); usleep(1000); } return 0; }
System hangs at this point.........
Please do let me know how file from CF card ->input stream?
