# Freertos-gdb Python module for user-friendly view freeRTOS-kernel objects in GDB ## Requirements GDB must built with python 3.6+ support Check your GDB with command: ```bash gdb -q -ex "python print('OK' if sys.version_info.major==3 and sys.version_info.minor>=6 else 'NOT SUPPORTED')" -ex "quit" ``` ## Install 1. Install the distro using `pip` ```bash pip install freertos-gdb ``` ## Run Start GDB and run the command ```bash python import freertos_gdb ``` Also, you could just update `.gdbinit` with this command ## Possible problems and solutions #### ModuleNotFoundError ```bash Traceback (most recent call last): File "<string>", line 1, in <module> ModuleNotFoundError: No module named 'freertos_gdb' Error while executing Python code. ``` #### Solution Check your `sys.path` inside GDB shell ``` python import sys; print(sys.path) ``` Append `sys.path` with a path to directory which contains `freertos_gdb` module. Or execute GDB with right `PYTHONPATH` env variable ## Commands You have `freertos` command with subcommands inside: ``` (gdb) freertos "freertos" must be followed by the name of a subcommand. List of freertos subcommands: freertos queue -- Generate a print out of the current queues info. freertos semaphore -- Generate a print out of the current semaphores info. freertos task -- Generate a print out of the current tasks and their states. freertos timer -- Generate a print out of the current timers info. .... ``` ## Examples ### Tasks ``` (gdb) freertos task CPU - Processing on CPU number ID - TCB_t task memory address PRI - Task priority B_PRI - Base priority. SS - Stack size. SL - Stack limit (available space left). CPU ID NAME STATUS PRI B_PRI MUTEXES_HELD SS SL ----- ---------- --------- --------- ----- ------- -------------- ---- ---- CPU0 0x3ffb6674 IDLE ready 0 0 0 1104 428 0x3ffb6dd4 IDLE ready 0 0 0 1104 428 CPU1 0x3ffbb724 SEM_RECUR ready 6 6 1 1680 364 0x3ffafd14 ipc0 suspended 24 24 0 564 456 0x3ffb4db4 esp_timer suspended 22 22 0 3648 444 0x3ffb3c54 ipc1 suspended 24 24 0 592 428 0x3ffb7734 Tmr Svc delayed_1 1 1 0 1584 460 0x3ffaf83c SENDER1 delayed_1 6 6 0 1600 444 0x3ffaf998 SENDER2 delayed_1 6 6 0 1548 496 0x3ffb909c READER1 delayed_1 6 6 0 1608 436 0x3ffb99fc READER2 delayed_1 6 6 0 1608 436 0x3ffba35c SEM_BIN1 delayed_1 6 6 0 1624 420 0x3ffbacbc SEM_BIN2 delayed_1 6 6 0 1592 452 ``` ### Queues, Semafores (and mutexes) To watch queues you must add them to registry via [vQueueAddToRegistry](https://www.freertos.org/vQueueAddToRegistry.html) ``` (gdb) freertos queue COUNT - Number of items currently in the queue. I_LEN - Length of the queue (number of items could hold, not the number of bytes). I_SIZE - Size of each item that the queue will hold. TASKS_WAITING_TO_SEND - Tasks that are blocked waiting to post onto this queue. TASKS_WAITING_TO_RECEIVE - Tasks that are blocked waiting to read from this queue. RX_LCK - Number of items received from the queue (removed from the queue) while the queue was locked. Set to queueUNLOCKED when the queue is not locked. TX_LCK - Number of items transmitted to the queue (added to the queue) while the queue was locked. Set to queueUNLOCKED when the queue is not locked. NAME COUNT I_LEN I_SIZE TASKS_WAITING_TO_SEND TASKS_WAITING_TO_RECEIVE RX_LCK TX_LCK ------ ------- ------- -------- ----------------------- -------------------------- -------- -------- TmrQ 0 10 16 0x3ffb7734 Tmr Svc -1 -1 queue1 10 10 4 0x3ffaf83c SENDER1 -1 -1 0x3ffaf998 SENDER2 queue2 0 10 4 0x3ffb909c READER1 -1 -1 0x3ffb99fc READER2 ``` ``` (gdb) freertos semaphore COUNT - Number of items currently in the queue. I_LEN - Length of the queue (number of items could hold, not the number of bytes). MUTEX_HOLDER - The handle of the task that holds the lock. RCALLCOUNT - Number of times a recursive mutex has been recursively "taken". TASKS_WAITING_TO_GIVE - Tasks that are blocked waiting to release a lock. TASKS_WAITING_TO_TAKE - Tasks that are blocked waiting to take a lock. NAME COUNT I_LEN MUTEX_HOLDER RCALLCOUNT TASKS_WAITING_TO_GIVE TASKS_WAITING_TO_TAKE --------------- ------- ------- -------------------- ------------ ----------------------- ----------------------- BINARY 0 1 0x3ffba35c SEM_BIN1 0x3ffbacbc SEM_BIN2 COUNTING 5 10 MUTEX 1 1 0 RECURSIVE_MUTEX 0 1 0x3ffbb724 SEM_RECUR 1628326 ``` ### Timers ``` (gdb) freertos timer TIMER_ID - An ID to identify the timer. OVERFLOW - True if timer has been overflow PERIOD_IN_TICKS - How quickly and often the timer expires. STATUS - Holds bits to say if the timer was statically allocated or not, and if it is active or not. TIMER_ID NAME OVERFLOW PERIOD_IN_TICKS STATUS CALLBACK_FN ---------- ------ ---------- ----------------- -------- --------------------------- 0x2 TIMER3 0 400 5 0x400d490c <vTimerCallback> 0x3 TIMER2 0 300 5 0x400d490c <vTimerCallback> 0x5 TIMER1 0 200 5 0x400d490c <vTimerCallback> 0x2 TIMER4 0 500 5 0x400d490c <vTimerCallback> ```
