Linker script generator produces build/esp32/esp32.common.ld from
components/esp32/ld/esp32.common.ld.in
This works fine until IDF is downgraded to V3.1 which uses components/esp32/ld/esp32.common.ld and
doesn't track build/esp32/esp32.common.ld at all.
At this point, the linker runs in the build/esp32 directory and "-T esp32.common.ld" picks up the
linker script generated .ld file, which causes mis-builds.
As reported on forums: https://esp32.com/viewtopic.php?f=13&t=9684&p=40105
Previously, this compiler flag was not being applied
regardless of CONFIG_SPIRAM_CACHE_WORKAROUND setting.
Explanation: add_compile_options() only applies to
source files added after the function is run, or in
subdirectories added after the function is run. In
this case, no new source files were being added after
this function was run.
Due to a hardware limitation in ESP32, the first four bytes of some
CSI data is invalid, not the last four bytes.
Correct a mistake of CSI sub-carrier index in documentation.
Added a new structure esp_app_desc_t. It has info about firmware:
version, secure_version, project_name, time/date build and IDF version.
Added the ability to add a custom structure with a description of the firmware.
The esp_app_desc_t is located in fixed place in start of ROM secotor. It is located after structures esp_image_header_t and esp_image_segment_header_t.
app_version is filed from PROJECT_VER variable (if set in custom make file) or PROJECT_PATH/version.txt or git repo (git describe).
Add API to get app_desc from partition.
1. add network channel switch function.
- users can obtain the new channel through the event MESH_EVENT_CHANNEL_SWITCH.
- the entire network will be moved to the same channel as the router without user intervention.
- if no router is in the network, users can call esp_mesh_switch_channel() on the root side to
move the entire network to their desired channel.
2. support not configuring the network channel.
3. support not configuring the router BSSID even if the router is hidden.
4. add allow_channel_switch to mesh configuration.
- if the channel is not specified, this value will be ignored.
- if the channel is specified and this value is set, when "fail" (mesh_attempts_t) times of parent selection
or look for networks are reached, device will change to perform a full channel scan for networks that could join.
- if the channel is specified and this value is set to 0, when a root is not elected, channel switch is not allowed.
but when a root appears, the root performs a full channel scan during the process of connecting to the router,
so even allow_channel_switch is set to 0, the root may still switch channel and eventually the entire network
changes channel.
5. add allow_router_switch to mesh router configuration.
- if the BSSID of router is not specified, this value will be ignored.
- if the BSSID of router is specified and this value is set, when the router of this specified BSSID fails to be found
after "fail" (mesh_attempts_t) times, the entire network is allowed to switch to another router with the same SSID.
6. modify the root to perform a full channel scan when esp_wifi_connect().
7. support handling beacon without DS Paramter Set.
This commit adds an option to enclose all FreeRTOS task functions within a
wrapper function. In the case that a task function returns, the wrapper function
will log an error and abort the application immediately.

Changes:
KConfig: The option CONFIG_ESP32_RTCDATA_IN_FAST_MEM is added in Kconfig file for esp32 component.
esp32.common.ld: added support of RTC_DATA_ATTR, RTC_RODATA_ATTR data placement into appropriate segment according to Kconfig option.
esp32.ld: linker script is modified to set alias for memory segment selected by Kconfig option to place data. The segments for force placement are added for RTC_FAST_ATTR, RTC_SLOW_ATTR attributes.
esp_attr.h: added new attributes RTC_FAST_ATTR, RTC_SLOW_ATTR for force placement into fest/slow memory.
test_rtc_fast.c: Added unit test cases to check data placement into appropriate memory segment.
Updated documentation for RTC_DATA_ATTR, RTC_FAST_ATTR, RTC_SLOW_ATTR in deep_sleep_stub.rst file.

The following commit rewrites the ESP-MESH docs. This commit includes
new diagrams and a structure approach to the mesh docs. Some mesh api references
have also been modified.
Guarantees that a component's project_include.cmake will be called after its dependent components'
project_include.cmake. Because of cycles in the dependency graph, this is less useful than you'd
think but it gives a strong guarantee for any component which is not part of a cycle.
Also applies deterministic ordering (ordering is initialised as COMPONENT_REQUIRES_COMMON then all
COMPONENTS in alphabetical order, but then the sorting by dependencies is applied.)
Hardware implements conditions LE, LT, GE, and conditions EQ and GT
are implemented in the assembler by emitting two JUMPS instructions
with other conditions.
The argument to ulp_run should be expressed in 32-bit words. Both the
address of ulp_entry and RTC_SLOW_MEM already are uint32_t*, so their
difference is the difference in addresses divided by sizeof(uint32_t).
Therefore the extra division by sizeof(uint32_t) is not needed.
Based on report on forum here:
https://esp32.com/viewtopic.php?f=13&t=6382&p=27514
Previous versions were much more relaxed about what could be in the partition
table, erroring out avoids unexpected changes on upgrade like different
partition offsets.
1. Move channel to the first row of the table.
2. Remove the condition of HT20/HT40 for they are determined by
secondary channel.
3. Clean up the CSI table.
The WiFi station connect sequence diagram does not have any "successful" ending.
It looks like a copy-paste error, because there are two consequent `SYSTEM_EVENT_STA_DISCONNECTED` events firing with nothing happening in between.
I think the original meaning was that the last event should be `SYSTEM_EVENT_STA_CONNECTED` to signify that if all goes well, that is the event that will be fired.

The old command caused was incorrect (x is “examine”, not “execute”)
and caused GDB register update only by chance. This replaces it with
“flushregs” command which purpose is exactly that — force GDB to
fetch registers from the remote.
Don't show the "Python 2 interpreter" option in menuconfig when using CMake.
This is a stop-gap until we support Python 2 & 3 together in ESP-IDF (soon).

This fixes multiple bugs with ring buffers and re-factors the code. The public
API has not changed, however the underlying implementation have various private
functions have been changed. The following behavioral changes have been made
- Size of ring buffers for No-Split/Allow-Split buffers will not be rounded
up to the nearest 32-bit aligned size. This was done to simplify the
implementation
- Item size for No-Split/Allow-Split buffers will also be rounded up to the
nearest 32-bit aligned size.
The following bugs have been fixed
- In copyItemToRingbufAllowSplit(), when copying an item where the aligned
size is smaller than the remaining length, the function does not consider
the case where the true size of the item is less than 4 bytes.
- The copy functions will automatically wrap around the write pointers when
the remaining length of the buffer is not large enough to fit a header, but
does not consider if wrapping around will cause an overlap with the read
pointer. This will make a full buffer be mistaken for an empty buffer
closes#1711
- xRingbufferSend() can get stuck in a infinite loop when the size of the
free memory is larger than the needed_size, but too small to fit in the ring
buffer due to alignment and extra overhead of wrapping around.
closes#1846
- Fixed documentation with ring buffer queue set API
- Adding and removing from queue set does not consider the case where the
read/write semaphores actually hold a value.
The following functions have been deprecated
- xRingbufferIsNextItemWrapped() due to lack of thread safety
- xRingbufferAddToQueueSetWrite() and xRingbufferRemoveFromQueueSetWrite()
as adding the queue sets only work under receive operations.
The following functions have been added
- xRingbufferReceiveSplit() and xRingbufferReceiveSplitFromISR() as a thread
safe way to receive from allow-split buffers
- vRingbufferGetInfo()
Documentation for ring buffers has also been added.
Added .rtc_noinit and .noinit section definitions into linker file /esp32/ld/esp32.common.ld.
The macro __NOINIT_ATTR, RTC_NOINIT_ATTR declared in esp32/esp_attr.h file.
Added unit test file to test added behavior for noinit variables and its attributes.
Added documentation changes for new added attributes.
Make some corrections after code review:
The linker file has been corrected to place noinit section before bss_start to make it safer.
Documentation file has been modified to clarify reset behavior of allocated data .
Corrected typos in test_noinit.c and removed assertion of noinit variable to avoid possible issues with ROM boot loader memory allocation.
