Legacy API of task watchdog used the same function esp_task_wdt_feed() to add and feed a task. This caused issues of implicitly adding a task to the wdt list if the function was used in shared code. The new API introduces init, adding, feeding, deleting, deinit functions. Tasks must now be explicitly added to the task watchdog using their handles. Deletion must also be explicit using task handles. This resolves the issue of implicit task additions to the task watchdog due to shared code calling esp_task_wdt_feed(). Task watchdog is now fully configurable at runtime by calling the init and deinit functions. Also added functions to get the handles of idle tasks of the other core. This helps when adding idle tasks to the watchdog at run time. Configuring the task watchdog using menu config is still available, however menu config will only result in calling the init and add functions for idle tasks shortly after the scheduler starts. Menu config also allows for using legacy behavior, however the legacy behavior willcall the new API functions but with slight variations to make them legacy compatible. Documentation and example have also been updated gcov_rtio.c headers updated to prevent error of freertos header files being included in the wrong order. Resolves issue TW#13265

Revision 1 of the ESP32 has a bug that can cause a write to PSRAM not to take place in some situations

when the cache line needs to be fetched from external RAM and an interrupt occurs. This enables a

|
fix in the compiler that makes sure the specific code that is vulnerable to this will not be emitted.

with the workaround and located in flash instead.

Because the external/internal RAM allocation strategy is not always perfect, it sometimes may happen

that the internal memory is entirely filled up. This causes allocations that are specifically done in
|

internal memory, for example the stack for new tasks or memory to service DMA or have memory that's

also available when SPI cache is down, to fail. This option reserves a pool specifically for requests

like that; the memory in this pool is not given out when a normal malloc() is called.

Set this to 0 to disable this feature.

Because some bits of the ESP32 code environment cannot be recompiled with the cache workaround, normally

ROM code in any way (no direct calls, but also no Bluetooth/WiFi), you can try to disable this and use

xTaskCreateStatic to create the tasks stack in external memory.

single base MAC address.

If the number of universal MAC addresses is four, all four interfaces (WiFi station, WiFi softap,

sequentially by adding 0, 1, 2 and 3 (respectively) to the final octet of the base MAC address.

If the number of universal MAC addresses is two, only two interfaces (WiFi station and Bluetooth)

addresses, respectively.
