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

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

tasks cannot be safely run with their stack residing in external memory; for this reason xTaskCreate and

friends always allocate stack in internal memory and xTaskCreateStatic will check if the memory passed

to it is in internal memory. If you have a task that needs a large amount of stack and does not call on
|
|
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.

Configure the number of universally administered (by IEEE) MAC addresses.

single base MAC address.

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

Bluetooth and Ethernet) receive a universally administered MAC address. These are generated

|
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.

If this option is enabled, NVS will be initialized and calibration data will be loaded from there.
|

PHY calibration will be skipped on deep sleep wakeup. If calibration data is not found, full calibration
|
|
will be performed and stored in NVS. Normally, only partial calibration will be performed.
|
|
If this option is disabled, full calibration will be performed.

If it's easy that your board calibrate bad data, choose 'n'.
|
|
Two cases for example, you should choose 'n':
|
|
1.If your board is easy to be booted up with antenna disconnected.
|
|
2.Because of your board design, each time when you do calibration, the result are too unstable.
|
|
If unsure, choose 'y'.

If enabled, PHY init data will be loaded from a partition.

When using a custom partition table, make sure that PHY data

partition is included (type: 'data', subtype: 'phy').

With default partition tables, this is done automatically.

If PHY init data is stored in a partition, it has to be flashed there,

otherwise runtime error will occur.

If this option is not enabled, PHY init data will be embedded

If enabled, application is compiled with support for power management.

This option has run-time overhead (increased interrupt latency,

longer time to enter idle state), and it also reduces accuracy of

RTOS ticks and timers used for timekeeping.

When APB clock frequency changes, high-resolution timer (esp_timer)
|
|
scale and base value need to be adjusted. Each adjustment may cause

|
small error, and over time such small errors may cause time drift.
|

If this option is enabled, RTC timer will be used as a reference to

compensate for the drift.

It is recommended that this option is only used if 32k XTAL is selected

If enabled, esp_pm_* functions will keep track of the amount of time

This feature can be used to analyze which locks are preventing the chip

in each power saving mode. This feature does incur some run-time
