- Technical details covered in section "15.3.2 Anti-DPA Attack Security
Control" chapter of the ESP32-C6 TRM
- Default configuration sets the security level low for the DPA
protection
- This change applies to all the crypto peripherals where the clock
frequency is dynamically adjusted to create randomness in the power
consumption trajectory
- This configuration helps to make the SCA attacks difficult on the
crypto peripherals
This commit adds support for the LP I2C peripheral driver to be used by
the LP core. An example is also added to demonstrate the usage of the LP
I2C peripheral from the LP core.
eFuse module has a hardware bug.
It is related to ESP32-C3, C6, S3, H2 chips:
- BLOCK9 (BLOCK_KEY5) can not be used by XTS_AES keys.
For H2 chips, the BLOCK9 (BLOCK_KEY5) can not be used by ECDSA keys.
S2 does not have such a hardware bug.
modem retention: Support esp32c6 wifi MAC and baseband sleep retention
sleep_modem: wifi MAC modem wakeup protect in modem state before PMU trigger sleep enable request
sleep modem: provide a interface to get whether the Modem power domain is allowed to power off during sleep
add i2c_ana master header file to project
auto beacon: release PMU's lock on root clock source (it is locked in the PLL)
wifi receiving beacon frame in PMU modem state strongly depends on the BBPLL
clock, PMU will forcibly lock the root clock source as PLL, when the root
clock source of the software system is selected as PLL, we need to release
the root clock source locking.
When it is judged that the PLL is locked by PMU after wakeing up from the PMU
modem state, switch the root clock source to the PLL in the sleep process (a
critical section).
auto beacon: fix the failure to receive broadcast/multicast frames in modem state
When the multicast field in the beacon frame received in the PMU modem state is
True, the PMU switches to the PMU active state (the PMU waits for the HP LDO to
stabilize and then restores the MAC context) and starts to receive
broadcast/multicast frames (Broadcast/Multicast frames will be sent after a
minimum delay of 48 us after the beacon frame), because the PMU waits for the HP
LDO to stabilize too long (~154 us), which will cause broadcast/multicast frame
reception to be missed.
auto beacon: select the PLL clock source as the REGDMA backup clock source when the PMU switches to ACTIVE from MODEM state
update Digital Peripheral (M2A switch) REGDMA restore time parameter
auto beacon: fix the issue that only channel 1 can connect to AP in modem state
usb_serial_jtag: Improve the code for the issue of usb cdc device unable to work during sleep
Closes IDFGH-6887
See merge request espressif/esp-idf!20973
1. Remove RTC_CLOCK_BBPLL_POWER_ON_WITH_USB Kconfig option
During sleep, BBPLL clock always gets disabled
esp_restart does not disable BBPLL clock, so that first stage bootloader log can be printed
2. Add a new Kconfig option PM_NO_AUTO_LS_ON_USJ_CONNECTED
When this option is selected, IDF will constantly monitor USB CDC port connection status.
As long as it gets connected to a HOST, automatic light-sleep will not happen.
Closes https://github.com/espressif/esp-idf/issues/8507
