On the V5 Brain I have vex OS 1.0.5
Pros version 3.1.6
On the Brain it also says “SD Card Installed” “Yes”
However, this simple prosv5 code
if ( (fp = fopen(“/usd/data1.txt”,“w”)) == NULL)
{
perror("write file error: ");
printf(“write file open error %s:%d\n”,FILE,LINE);
}
come back with “write file error: : No such device or address”
I cannot figure out what could be wrong. Just from the error it would seem that /usd mount point is not there? Any help is appreciated.
