Starcore ADS Crash

annoyedUser — Wed, 08 Nov 2006 22:34:31 GMT

I am using the MSC8122ads development board. I noticed a crash when I entered my program. I isolated the print statement and began to dig. Ultimately I discovered that the code went off the track and into the weeds (illegal instruction trap) at the point labeled below ( I believe it jumps in response to stream flag = 9 and goes to an incoherent instruction.)
I was told that I should try to get my problem fixed here since the development staff is overworked. Can anyone suggest a patch or a fix?
These values represent the initial conditions:
ptr = 0x23B60 ; size= 1 ; nmemb = 23 ; stream->_flag = 9 ;
After stepping from PC = 01012E7E this goes to illegal instruction land
This code is from fwrt__common_,c

/* check for basic errors */
if ( NULL == ptr || 0 >= size || 0 >= nmemb ||
( !( stream->_flag & _IOWRITE ) && !( stream->_flag & _IORW ) ) )
{
stream->_flag |= _IOERR;
return (size_t) 0;
}
/* check for basic errors */
if ( NULL == ptr || 0 >= size || 0 >= nmemb ||

Hello

For these kind of issues I can only recommend you to submit an SR through our on line support web page.

Our support staff will be looking into that.

Make sure to attach a project reproducing the issue and information on CodeWarrior product you are using to the SR.

To get CodeWarrior product information:

- Start IDE

- Select Help -> "About Metrowerks CodeWarrior"

- Click on "Installed Products"

- Click on "Save As". save the information in a text file and attach it to the SR.
