1. remove rc when ap not found
closes issue: https://github.com/espressif/esp-idf/issues/1797
2. allocate mimo packet to internal memory
3. use FRC2 timer instead of WDEV_NOW() for modem sleep to calculate
TBTT time.
It fixes the bug that TBTT will be incorrect if beacon is lost.
If the RTC crystal is bad or has no matched capacitance, then you do not need to start such the crystal. It is necessary to determine this case, output an error (about impossibility to start from the oscillator) and start from the internal RC of the chain.
Reduced the default value of the number of bootstrap cycles. Because we can oscillating the oscillator which then stops. (in Kconfig). Changed from 100 to 5.
The number of calibration cycles has been increased. It is the main criterion for estimating the launch of an oscillator. A large increase leads to an increase in the load time, as well as the stability of recognition of this case. (in Kconfig).
Changed from 1024 to 3000.
This fixes errors logged on the console: sdmmc_req:
handle_idle_state_events unhandled: 00000004 00000000
The issue happens if "data done" event occurs before "command done".
State machine code did not check *which* event occurred in
SENDING_CMD state, and went to IDLE or SENDING_DATA state on any
non-error event. In this case, we can't process "data done" event
until command has completed. This change introduces "unhandled event"
mask, which is carried over from one run of process_events to the
other. This allows waiting for the "command done" event to complete,
and then process "data done" event.
Ref TW17126.
CMD53 in byte mode supports transfers of any number of bytes between 1
and 512. This change removes limitation that the number of bytes must
be divisible by 4. Host quirk, that such transfers must be split into
two commands (one for the aligned part and the other one for
unaligned) is taken into account.
When two CPUs read the area of the DPORT and the area of the APB, the result is corrupted for the CPU that read the APB area.
And another CPU has valid data.
The method of eliminating this error.
Before reading the registers of the DPORT, make a preliminary reading of the APB register.
In this case, the joint access of the two CPUs to the registers of the APB and the DPORT is successful.
As of now, when Bluetooth debugs are enabled, all the messages are
mapped to BT_PRINTF which is mapped to ESP_LOGE. Hence, make monitor
shows all logs in red color which might lead to missing the actual
errors
This patch maps the Bluetooth messages to appropriate ESP_LOG* messages
and improves readability.
Also, make the BT trace level be configurable in menuconfig, so that
each layer of bt trace can be enabled/disabled.
Finally, add debug log control for BTC, OSI, BLUFI and clear up
Bluetooth debug logs.
So, with this the method of enabling Bluetooth logs is as follows:
1. make menuconfig -> Component config -> Bluetooth -> Bluedroid Enable
-> BT DEBUG LOG LEVEL -> set trace level for every layer of BT

It has been observed that, if external SPIRAM is enabled, then under

ALT header files for sha1, sha256, sha512 are only supposed to declare

Update hardware implementations of SHA functions, and other IDF
components which used above functions, to use new versions.
When light sleep is started, the other CPU gets halted using DPORT
stall mechanism. This can happen while it is inside an esp_timer
critical section, which may lead to a deadlock. This change adds
functions to take and release esp_timer lock before entering
DPORT critical section, preventing the deadlock.
1. Add error log if failed to store calibration version/mac/data
2. Change the NVS calibration version/mac/data store sequence
3. Pass the init_data instead of NULL to esp_phy_rf_init() in esp_phy_load_cal_and_init()
Currently when page is being freed, items are individually moved from
FREEING page to ACTIVE page and erased. If power-off happens during the
process, the remaining entries are moved to ACTIVE page during recovery.
The problem with this approach is there may not be enough space on
ACTIVE page for all items if an item was partially written before
power-off and erased during recovery. This change moves all the items
from FREEING to ACTIVE page and then erased the FREEING page, If
power-off happens during the process, then ACTIVE page is erased and the
process is restarted.

Command response tokens can be delayed from the original command by 1

Currently when MAX_STATION limit in DHCP config is set to N, dhcp server

Previous version of the code only connected CD and WP to the

signals automatically. This adds code to read CD and WP values when
command is executed and return errors if card is not present, or
write command is executed when WP signal is active.
Ideally suited for generating a binary externally, containing key-value pairs specific
to device manufacturers. Utility allows creation of a binary, compatible
with NVS structure, which can be separately flashed onto a new

different devices, e.g. serial numbers, but using a single firmaware
image.

Current code for recovery after power-off do not clean-up partially
erased items for FULL pages. If the erasure was part of modification
operation, this gets luckily cleaned-up because of duplicate detection
logic. For erase-only operation, the problem still exists. This patch
adds the recovery for FULL pages also.
Closes TW<20284>
When erasing a variable length item with an incorrect CRC32, the span
value of the item can not be trusted, so the item will be erased with
span = 1. Subsequent entries represent the data of the variable
length item, and these will be treated as separate items. For each
entry CRC32 is checked, the check most likely fails (because the
entry contains arbitrary data, and not a proper NVS item), and the
entry is erased. Erase function assumed that every item should be
present in cache, but it is not the case for the entries which are
just parts of item’s payload. This change allows for the item to be
not found in the hashlist, if the CRC32 check fails.
Current page selection algorithm selects a page for compaction based on just erased counts
and gives up when it does not find any page with erased count greater than 0. This is
problematic since the current allocation procedure skips the active page if there is not
enough room for the item in that page leaving free chunks on the pages. This change modifies
the algorithm to consider both erased as well as free counts on the candidate pages.
Closes TW<20297>

- In SPI mode, the card will respond to the initial SDIO reset (done
using CMD52) with “invalid command” error. Handle this correctly.
- sdmmc_card_init had a hack where GO_IDLE_STATE (CMD0) command was
sent twice. Add explanation why this is done, and don’t expect
correct response from the card on first CMD0.
- improve logs printed at debug level by adding CMD index
- Add SDIO support at protocol layer (probing, data transfer, interrupts)
- Add SDIO interrupts support in SDMMC host
- Add test (communicate with ESP32 in SDIO download mode)
Existing code assumed that response timeout is not followed by CMD_DONE,
which was not true, in fact. Host datasheet states that CMD_DONE is sent
after an RTO.
All the commands which do not have a response must have their flags set
accordingly. Therefore the host will not send RTO interrupt if response
is not expected. It is a bug in the code logic if it happens otherwise.
SDMMC host suffers from an issue that it outputs data near the rising
edge of the card clock, which is the edge used by the card to sample
data. If sampling time constraint is not satisfied, card may read data
after the transition.
The phases of output/input data can, in fact, be adjusted. However this
adjustment happens in the clock generation block outside of the host.
So the maximum phase change which can be created this way is equal to
half of the host clock period. So if the host clock is set to the lowest
possible frequency (for the given card frequency), then the phase offset
(and hence the hold time) will be the highest. This change modifies the
logic used to determine clock dividers accordingly.
sdmmc host: set correct dout phase and print correct frequency
SET_BUS_WIDTH is not a data transfer command. Extensive search in the
host datasheet and SD card spec did not reveal the origin of this hack
or 'feature'. Further testing showed that removing this does not lead to
regressions.
Fixes exceptions LoadProhibited, when rmt tries read variable p_rmt on RX END which can be 0.
It happens after esp_reset() (OTA) and the rmt is not probably stopped by it.

scenario:
register tx channel

- In some cases where the HTTP URL contains the port number

Purpose:
1. TLS calls can be too many, and require a user to know the expected behaviour. A simple TLS socket wrapper that can be used in any higher level protocol.
2. Uses OpenSSL compatibility layer, so applications using esp-tls can be built on the host, and it should just work on ESP
