help
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 (-mfix-esp32-psram-cache-issue) that makes sure the specific code that is
vulnerable to this will not be emitted.
This will also not use any bits of newlib that are located in ROM, opting for a version that is
compiled with the workaround and located in flash instead.

The ESP32 only supports 4MiB of external RAM in its address space. The hardware does support larger
memories, but these have to be bank-switched in and out of this address space. Enabling this allows you
to reserve some MMU pages for this, which allows the use of the esp_himem api to manage these banks.
#Note that this is limited to 62 banks, as esp_spiram_writeback_cache needs some kind of mapping of
#some banks below that mark to work. We cannot at this moment guarantee this to exist when himem is

If malloc() is capable of also allocating SPI-connected ram, its allocation strategy will prefer to
allocate chunks less than this size in internal memory, while allocations larger than this will be
done from external RAM. If allocation from the preferred region fails, an attempt is made to allocate
from the non-preferred region instead, so malloc() will not suddenly fail when either internal or

depends on SPIRAM_USE_MALLOC
default 32768
range 0 262144
help
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.
Note that because FreeRTOS stacks are forced to internal memory, they will also use this memory pool;
be sure to keep this in mind when adjusting this value.
Note also that the DMA reserved pool may not be one single contiguous memory region, depending on the
configured size and the static memory usage of the app.
config SPIRAM_ALLOW_STACK_EXTERNAL_MEMORY

depends on SPIRAM_USE_MALLOC
help
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.
During initialisation, MAC addresses for each network interface are generated or derived from a
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)
receive a universally administered MAC address. These are generated sequentially by adding 0
and 1 (respectively) to the base MAC address. The remaining two interfaces (WiFi softap and Ethernet)
receive local MAC addresses. These are derived from the universal WiFi station and Bluetooth MAC
addresses, respectively.
When using the default (Espressif-assigned) base MAC address, either setting can be used. When using
a custom universal MAC address range, the correct setting will depend on the allocation of MAC

ESP-MESH utilizes beacon frames to detect and resolve root node conflicts (see documentation). However the
default length of a beacon frame can simultaneously hold only five root node identifier structures,
meaning that a root node conflict of up to five nodes can be detected at one time. In the occurence of
more root nodes conflict involving more than five root nodes, the conflict resolution process will detect
five of the root nodes, resolve the conflict, and re-detect more root nodes. This process will repeat
until all root node conflicts are resolved. However this process can generally take a very long time.
To counter this situation, the beacon frame length can be increased such that more root nodes can be
detected simultaneously. Each additional root node will require 36 bytes and should be added ontop of the
default beacon frame length of
752 bytes. For example, if you want to detect 10 root nodes simultaneously, you need to set the beacon
frame length as
932 (752+36*5).
Setting a longer beacon length also assists with debugging as the conflicting root nodes can be identified
more quickly.

config PM_PROFILING
bool "Enable profiling counters for PM locks"
depends on PM_ENABLE
default n
help
If enabled, esp_pm_* functions will keep track of the amount of time
each of the power management locks has been held, and esp_pm_dump_locks
function will print this information.
This feature can be used to analyze which locks are preventing the chip
from going into a lower power state, and see what time the chip spends
in each power saving mode. This feature does incur some run-time
overhead, so should typically be disabled in production builds.
config PM_TRACE
bool "Enable debug tracing of PM using GPIOs"
depends on PM_ENABLE
default n
help
If enabled, some GPIOs will be used to signal events such as RTOS ticks,
frequency switching, entry/exit from idle state. Refer to pm_trace.c
file for the list of GPIOs.
This feature is intended to be used when analyzing/debugging behavior
of power management implementation, and should be kept disabled in
applications.
