Memprot functions are no longer placed by default in IRAM,
selecting ESP_PANIC_HANDLER_IRAM will still force panic related memprot
functions to be placed in IRAM.
esp_rom_spiflash_attach is called in cpu_start.c when it's
CONFIG_APP_BUILD_TYPE_RAM && !CONFIG_APP_BUILD_TYPE_PURE_RAM_APP.
This function will:
- reset MSPI
- configure MSPI IOs
- configure MSPI into slow read mode
Prior to this commit, this function is put quite late. It's OK for chips
earlier than C6. On C6 and H2, MMU registers are in SPI_MEM_x, so
resetting MSPI registers will also reset MMU registers.
After this commit, this funciton is called eariler, before
cpu_start.c: bootloader_init().
1. Fix deep sleep wakeup IOs can not be unhold issue
2. Correct hold related APIs' description
3. Fix gpio_force_hold_all API
docs: Add GPIO wakeup source to sleep_modes doc for ESP32C3 and C2
Functions used for burning this efuse would log, but at this point
esp_log is not initialized. Moved to a later point in the startup process.
Closes https://github.com/espressif/esp-idf/issues/9457
This commit marks all functions in interrupt_controller_hal.h, cpu_ll.h and cpu_hal.h as deprecated.
Users should use functions from esp_cpu.h instead.
The following two functions in bootloader_support are private now:
* esp_secure_boot_verify_sbv2_signature_block()
* esp_secure_boot_verify_rsa_signature_block()
They have been moved into private header files
inside bootloader_private/
* Removed bootloader_reset_reason.h and
bootloader_common_get_reset_reason() completely.
Alternative in ROM component is available.
* made esp_efuse.h independent of target-specific rom header
1. Clean up clk usage in IDF, replace rtc_clk_xtal/apb_freq_get with
upper level API esp_clk_xtal/apb_freq
2. Fix small errors and wrong comments related to clock
3. Add clk_tree_defs.h to provide an unified clock id for each chip
Modify the NGed drivers to adopt new clock ids
This commit updates the visibility of various header files and cleans up
some unnecessary inclusions. Also, this commit removes certain header
include paths which were maintained for backward compatibility.
The following files were deleted:
- components/esp_hw_support/include/soc/cpu.h
- components/soc/esp32s3/include/soc/cpu.h
The following functions are deprecated:
- get_sp()
The following functions declared in soc/cpu.h are now moved to esp_cpu.h:
- esp_cpu_configure_region_protection()
The following functions declared in soc/cpu.h are now moved to components/xtensa/include/esp_cpu_utils.h:
- esp_cpu_process_stack_pc()
All files with soc/cpu.h inclusion are updated to include esp_cpu.h instead.

There was race condition where interrupt entries set by APP cpu core
could have been cleared during PRO cpu startup.
This was observed while setting up "cache access error" interrupt in
SMP mode for ESP32-S3.
This fix allows to NOT modify or clear any entries set by other core
(APP or PRO) and thus avoiding any race conditions during startup code.
Check Memprot lock bit(s) during the system startup, abort/reset on any Memprot parts found locked during this phase.
There is no legal reason to disallow the Memprot configuration by the system, so it's either a critical bug in the
application or an malicious attempt to bypass the system security.
Error message is printed before digital system reset.
Closes IDF-2700
Software support for PMS module.
Allows controlled memory access to IRAM (R/W/X) and DRAM0 (R/W)
On/locked by default, configurable in Kconfig (esp_system)
Closes https://jira.espressif.com:8443/browse/IDF-2092
* Target components pull in xtensa component directly
* Use CPU HAL where applicable
* Remove unnecessary xtensa headers
* Compilation changes necessary to support non-xtensa gcc types (ie int32_t/uint32_t is no
longer signed/unsigned int).
Changes come from internal branch commit a6723fc
Sometimes the flash size read from bootloader is not correct. This may
forbid SPI Flash driver from reading the the area larger than the size
in bootloader header.
When the new config option is enabled, the latest configured
ESPTOOLPY_FLAHSIZE in the app header will be used to override the value
read from bootloader header.
- Introduce system time function and concept of system time provider.
esp_timer is system time provider when present.
- Set the reference point for system time, g_startup_time.
- Use the system time functions in newlib instead of calling esp_timer
functions directly
