21.3.8 Tsqware Sparclet

gdb enables developers to debug tasks running on Sparclet targets from a Unix host. gdb uses code that runs on both the Unix host and on the Sparclet target. The program gdb is installed and executed on the Unix host.

remotetimeout args
gdb supports the option remotetimeout. This option is set by the user, and args represents the number of seconds gdb waits for responses.

When compiling for debugging, include the options ‘-g’ to get debug information and ‘-Ttext’ to relocate the program to where you wish to load it on the target. You may also want to add the options ‘-n’ or ‘-N’ in order to reduce the size of the sections. Example: 

     sparclet-aout-gcc prog.c -Ttext 0x12010000 -g -o prog -N

You can use objdump to verify that the addresses are what you intended: 

     sparclet-aout-objdump --headers --syms prog

Once you have set your Unix execution search path to find gdb, you are ready to run gdb. From your Unix host, run gdb (or sparclet-aout-gdb, depending on your installation).

gdb comes up showing the prompt: 

     (gdbslet)
