Dear Group,

                I am testing the TEE on QEMU v7 with my own proprietary TEE client and TA application. So, debug the normal world application, I followed the steps as explained in the section “GDB – Normal world” as explained in the link below. But I am facing the error in the normal world window when I try to attach the GDB to the normal world application as below.

Window from where I am trying to attach GDB:

(gdb) target remote :12345

Remote debugging using :12345

No executable file now.

warning: Could not load vsyscall page because no executable was specified

0x76fd5b40 in ?? ()

(gdb) b main

No symbol table is loaded.  Use the "file" command.

Make breakpoint pending on future shared library load? (y or [n]) n

Normal World Application window:

# gdbserver :12345 tls_server

Process tls_server created; pid = 738

Listening on port 12345

Remote debugging from host 10.0.2.2

                Can someone enlighten me on how to fix this issue?     

Regards,
