gdb issue when debug a freeRTOS & C++ project

gschelotto — Thu, 23 Feb 2017 10:31:08 GMT

Hi,

I'm working with LPCxpresso IDE 8.2.2 and JLink debugger with no problem on a LPC1788. I can compile & debug the LPCOpen projects as expected and also migrate C applications to C++. The problem is when I try to debug a basic (1 task) freeRTOS in C++. The compilation ends successfully but here's the error dialog when gdb starts

then, when I press the Debug button...

and finally... no debug sesion is started

Any hints? How can avoid this issue?

regards,

gaston

Sounds like an issue between GDB and the J-Link server, or maybe in the GNU ARM Eclipse plugin for J-Link - if that is what you are using. I'm afraid that there isn't much advice we can provide on these. Good starting point might be The J-Link debugging Eclipse plug-in

It seems that no matter if the code is written in C or C++. I'm working with last link plugin (4.1.2.201701141320) and jlink driver (v6.14). The issue seems to be related to the number of opened projects. If I just imported the PSU (lpc_xxx projects are necessary to build) everything goes well.

However in the next scenario I'm not able to debug the PSU project, as shown in the previous post.

I've also used another debug probe (P&E Multilink Universal with its latest eclipse plugin & driver) with the same (bad) results. So It seems the issue does not related to the jlink tool

Lack of memory problem maybe? (I'm running on W7 Professional 32-bit and 3GB RAM)

I will continue investigating anyway...
