Debugging troubles with LPC1769 when hovering with mouse over array

Hello,

I'm using LPCXpresso board with CodeRed LPCXpresso software. I'm using default unmodified CMSIS2 library and USB library from base board (RDB1768cmsis2_usbstack).
(Default 12MHz clock without any modifications of PLL settings in library)
I made sure that workspace is clean and with default values by switching to other workspace and reimporting all libraries and examples from archives.

When I hover the mouse cursor over relatively large array (8192 B) I get an error:
15: Target error from Read Memory Not connected

If I do the same for small array or variable it is working OK (I can see LED blink on LPC-Link board every time I hover the mouse over some variable).

I can also step over or into functions without any problem just until I hover the mouse over such array.

Is there any setting for communication timeout or maybe for defining maximum array length read back to IDE?

I'm on the very tight schedule so I need answer asap.
Any suggestions?

Regards, Darko

OK. I can replicate the problem. It appears to be some strange corner case timeout transferring very large blocks of data when hovering.

I'll flag this for further investigation and fixing in a future LPCXpresso release. For the moment I am afraid that I can only suggest avoiding using hover on very large arrays- and instead, for example, use the variable view.

Note that this only seems to affect LPC-Link, not Red Probe+ or the RDB-Link on our RDB1768 board. Thus you could consider using a Red Probe+ instead of LPC-Link.
