When I use Single Step Target a asm Program,the CCS2.1 occur a message
like this:"Unexpected Fatal Error Encountered which may have been caused by a stack
overflow,out of memory condition,or access violation.I'm going to try and save your work before
TERMINATING this application."I doubt that FIRS instruction cause this problem.Is FIRS work on
DARAM?How can I to solve this problem?My program and cmd file is as follow:
;****************fir5.asm*******************

That's a CCS/Windows error box saying that CCS has eaten itself alive and is in the process of crashing nicely. I wouldn't recommend letting it save the workspace or anything else it wants to do, it tends to corrupt whatever it tries to preserve. CCS 2.2 does this a little less often, but is still not what I would expect after paying a couple of K for a piece of software. It still has memory leaks that use up windows resources after opening/closing CCS multiple times without rebooting the machine. I sure wish there were a GCC target for the C5xxx series.
