For updates, this binary is located in "TBD", with a filename vxWorks. One interesting command " d " allows to display memory. Another vxWorks lkup allows to find all symbols with there associated address these dumps are totally useless as vxWorks. There are three identified segments :. TOC r2 : 0xA5F80 Problem, it points in the middle of a very large data array, an deflated bmp picture. Could be ok if r2 is a computed value to optimized opcode At 0x there is a Symbol Table which is made of symbols.
In earlier tutorials, we saw how to create, use and delete the tasks. In this tutorial, we will see how to Suspend and Resume the tasks. Check this link for more details.
Like Linux, VxWorks is a multi-task OS and is a "real-time" OS because the programmer can have control on the way the tasks are executed the "scheduling". VxWorks is a "preemptive" multi-task OS: each task has a priority level ranging from 0 for the highest priority to for the lowest priority. When a resource needed for T2 is missing, T2 is turned in "pending" state. If the execution of T2 has been completed, T2 is discarded from the schedule. When two tasks with the same priority level must be managed, VxWorks can use the "Round-Robin" scheduling: the CPU will spend alternatively a certain amount of time "time slice" on each task until they are completed.
