Pulp GNU ToolChain Not throwing L2 Overflowed Error
#1
Hi,
   I am currently working with L2 Memories. I notice that even though the size of the stimuli file I have is larger than the total size of L2 private memory (0x1c010000). The compiler does not throw l2 overflowed by ... bytes error. i have not changed the /my-path/pulp-sdk/pkg/sdk/dev/install/rules/pulpissimo/link.ld file. 

This the command the make file of hello example uses to compile my code

Any idea why the pulp_gnu_toolchain did not throw any error. does the pulp_gnu_toolchain should be rebuilt because i am playing by extending the Private memory sizes although the above error was produced with no change in the pulpissimo or pulp-sdk code
