1. fix the bug. Modify the condition that esp_bt_controller_mem_release() shoud be only called before esp_bt_controller_init() or after esp_bt_controller_deinit()
2. modify the example to use esp_bt_controller_mem_release()
libc time function now rely on esp_timer_get_time as the source of
high-resolution time, rather than FRC1 timer. Internally, on the ESP32
esp_timer implementation uses FRC2 timer.
- Change help text and labels in Kconfig to use "high-resolution timer"
instead of FRC1. Keep existing Kconfig option name to be backwards
compatible.
- Change references to "FRC1" in the source code to "FRC".
Replace explicit masks and shifts with bit fields when working with FATFS date and time representations. Also zero-initialize remaining members of struct tm.
Fixes https://github.com/espressif/esp-idf/issues/1369.
A couple of typos referencing tx_ring_buf when rx_ring_buf, slv_tx_mux
instead of slv_rx_mux.
Also, I2C_ENTER_CRITICAL()/I2C_EXIT_CRITICAL() usage was not consistent.
Only some of the _set_ functions had them. Most of the _get_ function
had them? It is my understanding that they should be wrapped around
writes, not reads? (I think we still need the lock for reading pairs of consistent values)
Also, the ticks_to_wait timeout handling in i2c_master_cmd_begin() would
not handle integer rollover correctly.

Previously SDSPI host driver would rely on retry count when waiting for
the card to read or write data. This caused different timeout times
depending on CPU frequency and card clock frequency. In practice, card
performance does not depend on these two factors.
This change uses timeout_ms field of sdmmc_command_t introduced
previously for SDMMC host.
Fixes https://esp32.com/viewtopic.php?f=2&t=3440&p=16037 and similar
issues related to SDSPI timeouts.
FATFS does not support f_stat call for drive root. When handling stat
for drive root, don't call f_stat and just return struct st with S_IFDIR
flag set.
Closes#984
A function to change "in IRAM" status for an existing interrupt handle, without going through free/allocate of the interrupt.
mOS HW timer implementation requires this to make HW timers safe to re-set from an IRAM ISR.
This is a wrapper API for creating a Ring Buffer, which ensures that
the ringbuffer can hold the given number of items, each item being of the
same given length.

Useful to check if the next item to receive is wrapped or not.
This is valid only if the ring buffer is initialised with type
RINGBUF_TYPE_ALLOWSPLIT.
This is as per the feature request here:

The earlier available API (xRingbufferGetMaxItemSize())just gives
a static max entry value possible for given ring buffer.
There was a feature request for an API which could provide
a real time available buffer size. See below:
