I'm getting the "One or more breakpoints could not be set and have been
disabled" message, even though I'm only trying to set one. Have I
inadvertently thrown a switch?

Using IAR 4.0 and an MSP430F2272 with TI USB FET and JTAG.

I've been through the manual and the project settings, but I'm just not
getting it this A.M.

Hi

You are trying to set an hardware or a software breakpoint?

I guess it would be a software breakpoint - on a line of code.

When you debug c-code, IAR will automatically set up one Breakpoint at
where the startup code calls "main()" and it will not tell you that a
Breakpoint is used there.

F2272 has two "Beakpoint Registers". A Data Breakpoint will use up
both "Breakpoint Registers". Range Breakpoint is not supported on F2272.

Thanks for the feedback. I haven't set up a Data Breakpoint or tried
a Range breakpoint.

I think I have something set wrong, but for the life of me can't find
it yet.

My 'red dot' on a code line gets 'whited out'.

This had been working for me. Alas, still learning a new tool.

Hi

The user old_cow_yellow is correct. So I sugest that you read the
application note SLAA263.pdf that explain how to use the MSP430 EEM
debug feature with IAR 3.30.

The number of software breakpoints is not limited.

Best regards
AES

This has happened to me too. Usually, the breakpoint was on a piece of
code that is no longer used (not called from anywhere or optimized
away). When pressing the Debug icon to load the microcontroller and
start debugging, then I get that error.

As far as I know, the number of breakpoins IS limited by hardware. For
example the MSP430F12x has 3 while the MSP430F16x has 7. To use
additional breakpoints, these have to be created as "virtual
breakpoints",in which case IAR has to go into something called
singlestepping or microstepping mode. This are not really breakpoints,
as IAR tells the uC to execute one instruction each time and when it
reaches the virtual breakpoint, IAR stops telling the uC to execute
the next instruction. This results in a very low executing speed.

At least this is the way I understand it.
