Some RTC features are synchronized to RTC_SLOW_CLK, so sometimes
software needs to wait for the next slow clock cycle.
This function implements waiting using Timer Group clock calibration
feature.
If VDDSDIO is controlled by RTC (which is the case when using 1.8V flash
and CONFIG_BOOTLOADER_VDDSDIO_BOOST is enabled), need to allow VDDSDIO
to be controlled by the state machine before going into deep sleep.
1. raise vddsdio for 1.8v flash
2. gpio matrix config for flash
3. fix esp_restart function
todo:
to decide whether to raise core voltage
to test deep-sleep current
In some cases, xPortGetCoreID was not inlined, and ended up in flash.
Since this function is used in many situations when cache is disabled,
that caused exceptions. Adding IRAM attribute to fix that.
When debugging crashes caused by flash cache access errors, OpenOCD may
request the value of uxTopUsedPriority when cache is disabled. Placing
it into IRAM to avoid an error in such case.
Previously NVS did check CRC values of key-value pairs on the active
page, but the check for full pages was missing. This adds the necessary
check and a test for it.
SDMMC hardware treats all buffers as aligned, and ignores 2 LSBs of
addresses written into DMA descriptors. Previously SDMMC host driver
assumed that data buffers passed from SDDMC command layer would be
aligned. However alignment checks were never implemented in the command
layer, as were the checks that the buffer coming from the application
would be in DMA capable memory. Most of the time this was indeed true.
However in some cases FATFS library can pass buffers offset by 2 bytes
from word boundary. “DMA capable” restriction may be broken if pSRAM
support is used.
This change adds buffer checks to the SDMMC host driver (alignment and
DMA capability), so that the host layer will error out for incompatible
buffers. In SDMMC command layer, a check is added to read and write
functions. If an incompatible buffer is passed from the application, new
buffer (512 bytes size) is allocated, and the transfer is performed
using {READ,WRITE}_SINGLE_BLOCK commands.
1. Remove the bond_device global variable.
2. Fix bond_device add cause memory exception
3. Modify the code location.
4. modify thread security
5. remove esp_ble_clear_bond_device_list() API
6. modify esp_ble_get_gond_device_list() to return list immediately, rather than wait event.
7. modify the gatt_security_server demo to show how to remove all the bonded devices.
8. fix some code bugs may cause something error.
9. modify gatt_security_server demo
If destination IP address of the packet is broadcast address, firstly compare
source IP address with the that of each network interface. If it matches,
packet is forwarded from the interface.
