Re: Developer Guide to GDB

[Ramana Radhakrishnan <ramana.radhakrishnan@codito.com>]

Hi,


There are newer versions of GCC and binutils than that and which support
the core you want. 
http://www.codito.com/arc/download.html

GDB is something that is in the pipeline but depends on user demand for
the A4 core. We have 6.3 based GDB for the later versions in our tree
which is yet to be merged back . It does not yet support the A4. 
 

cheers
