With all do respect.. I have used Eclipse before (CCS, LSI) but my LPCXpresso version hasn't some debug
features I need:

- disassembly window (and other windows) de-attach mode - why am I forced to be in the same window instead on other monitor?
- breakpoints cannot be edited ? I have to remove and add new to change address?
- disassembly window - hide opcodes isn't working at all
- disassembly window - absolute impossible to stop at breakpoint if not set from C code

I try to stop at before fetch crt_init but isn't working.

- disassembly window - step return isn't working at all
- disassembly window - horrible slow refresh and is not working until one step (F5)

Am I missing something, do I need a patch or something?
(LPCXpresso v6.1.4 [Build 194] [2014-01-15])

Too bad.. I like LPC family already.

Best regards,

PS. Where is the simulator ?!

Detaching of Views works fine here.

Currently you can edit the line value for breakpoints set directly on source, but as you highlight you can't edit breakpoints set on addresses in the same way. I'll flag for this to be looked into.

Due to limitations in the Eclipse opcode display mechanism, we actually provide LPCXpresso specific opcode handling. To toggle the display of opcodes on go to:

Window -> Preferences -> LPCXpresso -> Disassembly

and tick the box to turn opcodes on. You will then need to use the Disassembly view's "Refresh View" button.

Please explain what you mean. There should be no problem setting a breakpoint in the start up code.

No issues noted here.

We don't supply one and have no plans to do so.

If you want further assistance, please provide more details of exactly what actions you are carrying out, what host OS you are using, which debug probe and what target MCU, so that we can try to replicate your issues.

One final point to note, given your interest in breakpoints, is that there are limits on the number of breakpoints that can be set on code being run from flash. Typically this is 4 or 6 depending upon the MCU being used:

And remember that things like stepping etc will typically require a free breakpoint unit.
