Subject: [oc] ZPU
I've got another step further, I noticed that the Java "MakeRam" utility
tends to leave a few bytes off the end. I'm not much of a Java person so
I re-wrote it in C. Here it is. You could include it in the ZPU CVS if
you think it useful.

My code unfortunately still doesn't run.

// zpuromgen.c

#include <unistd.h>
#include <stdio.h>

typedef uint8_t BYTE;

main(int argc, char **argv)
{
BYTE opcode[4];
int fd;
int addr = 0;
ssize_t s;

// Check the user has given us an input file.
if(argc < 2)
{
printf("Usage: %s <binary_file>\n\n", argv[0]);
return 1;
}

// Open the input file.
fd = open(argv[1], 0);
if(fd == -1)
{
perror("File Open");
return 2;
}

while(1)
{
// Read 32 bits.
s = read(fd, opcode, 4);
if(s == -1)
{
perror("File read");
return 3;
}

if(s == 0)
break; // End of file.

// Output to STDOUT.
printf("%6d => x\"%02x%02x%02x%02x\",\n",
addr++, opcode[0], opcode[1],
opcode[2], opcode[3]);
}

close(fd);
return 0;
}
