Title: Troubles with uTasker Simulator (Unhandled Exception)
Post by: paulk on October 30, 2009, 08:16:09 PM

First, let me say hello!  I'm new to the world of highly embedded, powerful microprocessors, and am exited to use a tool like uTasker to discover it.

I'm running the tutorial for the LM3Sxxxx parts.  Everything is going well, but I ran into a hitch with the simulator.  Basically, it works, and I can ping, http, and FTP to the simulator, but when I do an FTP "dir" command, it crashes with the following error:
(http://i38.tinypic.com/11r819x.jpg)

When I hit "break", it takes me to the line with the "while" loop in the following code:

Code: [Select]

static USER_FILE *fnNextUserFile(USER_FILE *ptrFiles, MAX_FILE_LENGTH *FileLength, unsigned char *ucMimeType)
{
    while ((ptrFiles != 0) && (ptrFiles->fileName != 0)) {
        if (ptrFiles->ucProperties & FILE_INVISIBLE) {
            ptrFiles++;                                                  // jump the invisible file
            continue;
        }
        *FileLength = ptrFiles->file_length;
        *ucMimeType = ptrFiles->ucMimeType;
        return ptrFiles;
    }
    return 0;                                                            // no more user files
}

Any ideas?  I took out the "dir" statements from the file referenced to by the .bat file, but I'd like to trace this problem.

Hi Paul

This is an error in the present release version as described in the following thread:
http://www.utasker.com/forum/index.php?topic=718.msg3165#msg3165

Simply change #define user_files_are_in_internal_flash 1 to#define user_files_are_in_internal_flash 0 (in ftp.c) and it will then operate correctly in the simulator (this is a simulator issue so doesn't change anything on the HW target).

Regards

Mark
