Easy debugging of embedded Linux

I am developing an application that runs on a small Linux SBC server (~ 32 MB RAM). Unfortunately, my application has recently become too large to work under GDB. Does anyone know of any good, easy debugging methods that I can use in embedded Linux? Even the ability to view the trace of a thread stack will be extremely useful.

I have to mention that this application is written in C ++ and runs several threads, therefore gdbserver does not work as it does not work with multi-threaded applications.

Thanks in advance,

Maha

Gdbserver really works with multi-threaded applications. However, you need to compile a cross-target debugger for your host so that it works with your target gdb.

For details on how to do this, see this article:
