writewordFormatwriteword id vaddr data What This Tool Does It writes data to a target system location. Specifically, it sends a request to write a word into the memory space of the target system by using the dbgif tool. The id is the thread number. Even though all threads share the same address space, you must still specify a thread. This command is shared with other debuggers in which threads may have different address spaces. The virtual address vaddr is the location to write, and it must be on a word boundary. The 32-bit data is the value to be written. Before execution of this command, the dbgif program must be running and the METHOD environment variable must be set to indicate whether this is a request for the R4300 CPU or the coprocessor. The value zero represents the CPU and the number one represents the RCP. In csh, this is accomplished by specifying: setenv METHOD 0If METHOD is set to 1 and the co-processor is running, the request will probably fail (as it should). It is generally unwise to use METHOD 1 for this command anyway; all addresses may be accessed from the CPU. Bugs In the event of a communications failure, the program will dump core. If that happens, you will need to remove the core file manually. See Also dbgif listthreads readmem
