I tracked down the error message. It's coming from this piece of code
sprintf((char *)tmpString, "P %ld %ld\r\n", Sector, Sector);
SendComPort(tmpString);
ReceiveComPort(Answer, sizeof(Answer)-1, &realsize, 2,5000);
sprintf((char *)tmpString, "P %ld %ld\r\n0\r\n", Sector, Sector);
if(strcmp((const char *)Answer, (const char *)tmpString) != 0)
{
printf("Wrong answer on Prepare-Command (2) (Sector
%ld)\n", Sector);
OutputErrorMessage(GetErrorNumber(Answer));
exit(4);
}
The prepare command is documented as taking a start sector and an end
sector number and so something like
P 2 2
should be sent to the micro. Unless echo is turned off then that should be
echoed back followed by the return code number (which should be 0 for
CMD_SUCCESS).
It's apparently not getting that but the code is converting whatever is
received to a number and then to an error message. If you can compile the
code try inserting the following line
printf("Expected [%s] -- Received [%s]\n", tmpString, Answer);
That may help track down what is actually happening.
