EWSTM8 of IAR - problems with breakpoints

Dear,


I have been trying IAR EWSTM8 Beta version. This beta version has solved a = problem with crashes as result of Live Watch activation and yet some improv= ements. Still, one of the annoying issues with EWSTM8 is breakpoints.=20 When breakpoint breaks the program, I can't run or go step-by-step, until t= he breakpoint is removed, so it is not so convenient. As well, sometimes I = see some communication timeout errors. The 1st problem occurs in the most p= laces in my program, but there are some places where it works properly. In = my work we have 3 EWSTM8 seats and the problem is visible in everyone of th= em. Nevertheless, at IAR site the problem is not reproducible, so they're s= tuck.



I'm kindly asking here, if somebody has been facing the same problem or hav= e some other issues, to share them here. It would be very important also to= get your understanding of the problem.=20



Thank you, E.L.

I am curious what kind of Beta version this is. Sometimes an unofficial patch is sent to specific customers with problems and sometimes chip vendors receive a pre-release version or patch that they can sometimes re-distribute to their key customers.

That sounds like you hit a hard limit of the number of breakpoints supported by the debug environment (debug probe + on-chip debug hardware). Note that some features require a breakpoint to be available.

Communication between what and what?

Do they have access to the same target board as you are using?

Dear Boudewijn Dijkstra,

Thank you for you comments.

Regarding the breakpoints, it's obviously not a matter of number of breakpoints, since if I removing a BP to another place, the problem is being solved. IAR cannot reproduce the problem, since we work with different HW targets and source code. I thought to send that them but because I have been assuming that the project is going to be completed, I haven't done it yet.

Communication error mentioned here is the communication between the IAR debugger and my target by means of SWIM bus.

Best regards, Eli
