This commit removes the riscv_interrupts.h header is it has become redundant. The previously
exposed API has been handled as follows:
- "riscv_interrupt_enable()" and "riscv_interrupt_disable()" have been removed. These functions
were declarations only and never had any implementation.
- "riscv_global_interrupts_enable()" and "riscv_global_interrupts_disable()" renamed to
"rv_utils_intr_global_enable()" and "rv_utils_intr_global_disable()" respectively and now
placed in rv_utils.h
ESP32-C2 has a single group timer, thus it will use it for the interrupt watchdog,
which is more critical than the task watchdog. The latter is implement in
software thanks to the `esp_timer`component.
This commit gives basic mmu driver framework. Now it is able to maintain
mmu virtual address usage on esp32, esp32s2 and esp32s3. Usage to
external virtual address should rely on mmu functions to know which
address range is available, instead of hardcoded.
This commit also improves psram memory that is added to the heap
allocator. Now it's added to the heap, according to the memory
alignment.

sizeof(time_t) was previously switched from 4 to 8, ROM functions that use
time_t or dependent types (such as "struct stat") are no longer called due as
they still treat sizeof(time_t) as 4 (see commit
24c20d188e).
However, there is a ROM callpath that was left out. If putchar is the first
stdio print related call, the call path will result in cantwrite() ->
__swsetup_r() -> __smakebuf_r() -> __swhatbuf_r() using the ROM "struct stat"
(where sizeof(time_t)==4).
Instead of removing all printf related ROM newlib functions (which will result
in increased binary size), this commit adds a workaround to setup the stdio
files before any print related calls occur.
This results in cantwrite() always returning false, thus the callpath described
above never being reached.
Closes https://github.com/espressif/esp-idf/issues/9269
esp_light_sleep_start() will stall the other CPU via esp_ipc_isr_stall_other_cpu(). After stalling the other CPU,
will call esp_clk_... API which themselves take locks. If the other stalled CPU is holding those locks, this will
result in a deadlock.
This commit adds a workaround calling esp_clk_private_lock() to take the lock before stalling the other CPU.
For RISC-V and Xtensa targets, in case a panic needs to happen when
Task WDT is triggered (ESP_TASK_WDT_PANIC), the interruptee's stack
is now used for printing the backtrace.
Abort after Task Watchdog is triggered can happen on APP CPU (second core).
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
ESP32-S3 stacks have currently have less useable space compared to other targets (due to
AI coprocessor context registers). This has caused a stack overflow in the IPC tasks under
some configurations. This commit increases the default IPC stack size for the ESP32-S3.
Blocking read from cdcacm VFS could return less bytes than requested.
This didn’t match the behaviour of other VFS drivers, and higher level
code could misbehave.
Previously, reset over USB CDC was done by calling esp_restart from
an interrupt handler. This works only until some restart hook function
is registered using esp_register_shutdown_handler, and the hook
function tries to do something that isn’t allowed in an interrupt
handler. One such case is with Wi-Fi. When Wi-Fi driver is installed,
it registers esp_wifi_stop as a shutdown handler function. However
esp_wifi_stop cannot be called from an ISR, and hence we shouldn’t
call esp_restart from an ISR either.
This commit modifies USB CDC driver to call esp_restart by posting it
to esp_timer task.
Closes https://github.com/espressif/esp-idf/issues/7404
Spinlocks themselves do not constitute critical sections as after a spinlock is acquired, interrupts
can remain enabled. However, there are some places where spinlocks are used direclty instead of using
the portMUX_TYPE and portENTER_CRITICAL_...() APIs. This commit fixes those calls.
- Remove esp_cpu_in_ocd_mode() from esp_cpu.h. Users should call esp_cpu_dbgr_is_attached() instead.
- Remove esp_cpu_get_ccount() from esp_cpu.h. Users should call esp_cpu_get_cycle_count() instead.
- Remove esp_cpu_set_ccount() from esp_cpu.h. Users should call esp_cpu_set_cycle_count() instead.
- Other IDF components updated to call esp_cpu_dbgr_is_attached(), esp_cpu_get_cycle_count() and esp_cpu_set_cycle_count() as well.
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
* Some components have initialization dependencies. To account for
them, simple numeric priority values are introduced.
* esp_system_init_fn_array moved into Flash from DRAM
* System init functions defined using ESP_SYSTEM_INIT_FN now return
an error code. This enables simpler and more consistent error
handling in the init functions. Returning an error from an init
function is now a valid approach — the startup code will print
an error and abort.
1. Since the baud rate in the ROM cannot be changed,
set the default baud rate of the 26Mhz version
of esp32c2 to 74800
2. Since the systimer configuration of the 26Mhz
version requires a non-integer systimer frequency
configuration, and this feature is not supported
in the current ROM, this option is disabled for
the 26Mhz version esp32c2
1. Rename MACROs SYSTEM_WIFI_RST_EN register bit fields to be more recognizable
2. reset Bluetooth baseband and clock bits to fix the issue of task watchdog triggered during controller initialization due to invalid hardware state
Adding prop and lit sections to the ELF will let the debugger and the disassembler
have more info about data bytes present in the middle of the Xtensa
instructions, usually used for padding.
The change fixes thread-local-storage size by removing .srodata section
from it. It initially was included in TLS section by mistake.
The issue was found when stack size increased after building applications
with GCC-11.1 compiler. Stack size became bigger because some new data
appeared in .srodata. See more details here:

SMP FreeRTOS uses a single kernel lock for all critical sections. There is a known
issue with esp_ipc_isr_stall_other_cpu() that can cause dead if the other CPU is
already in a critical section.
This commit adds a temporary workaround to reduce the chance of deadlock by taking
the SMP FreeRTOS kernel lock first before stalling the other CPU.
See IDF-5257 for more details.
The previously used splits between memory allocated for ROM code,
2nd stage bootloader and the app were somewhat safe and conservative.
This resulted in some space being unavailable for static allocation
in the app.
This commit increases the space available for static allocation to the
maximum possible amount.
1. Some of the ROM code static allocation is only used in UART/USB/SPI
download modes. This region ("shared buffers") has been placed at
the lower end of ROM memory area, to be reusable in flash boot
mode. The 2nd stage bootloader linker script is modified to "pack"
all sections exactly up to the end but with roughly 8K margin between
startup stacks.
2. Instead of calculating the sections placement and hardcoding the
addresses in the LD script again, rewrite it to calculate the
start address of each memory region automatically based on the
logic above.
3. Adjust the app memory layout (SRAM_IRAM_END) accordingly,
increasing the space available for static allocation.
Overall these changes increase the space available for static
allocation by about 78kB.
The downside of these changes is that the 2nd stage bootloader .data
segment is now directly adjacent to the startup stack on the PRO CPU.
Previously, there was effectively about 78kB of extra stack space for
the PRO CPU, before the stack would run into the data segment.
This commit makes changes to cpu_ll.h, cpu_hal.h, and interrupt_controller_hal.h:
- Moved to esp_hw_support in order to be deprecated in the future
- HAL/LL API now route their calls to esp_cpu.h functions instead
Also updated soc_hal.h as follows:
- Removed __SOC_HAL_..._OTHER_CORES() macros as they dependend on cpu_hal.h
- Made soc_hal.h and soc_ll.h interfaces always inline, and removed soc_hal.c.
This commit also updates the XCHAL_ERRATUM_572 workaround by
- Removing it's HAL function and invoking the workaround it directly the bootloader
- Added missing workaround for the ESP32-S3

The problem with the new format is that it is hard to parse and
breaks the parser that is used by PlatformIO. The old format
is much more reasonable. I do not see how the pattern in IDFDUT.py
can work with the new format, due to the missing space after the :
This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.
The behavior of portSET_INTERRUPT_MASK_FROM_ISR() has changed in SMP FreeRTOS. It's
previous behavior is now implemented in portDISABLE_INTERRUPTS() and portRESTORE_INTERRUPTS().
This commit replaces all portSET_INTERRUPT_MASK_FROM_ISR() and portCLEAR_INTERRUPT_MASK_FROM_ISR()
calls with portDISABLE_INTERRUPTS() and portRESTORE_INTERRUPTS() respectively
When configNUM_CORES = 1, vTaskCoreAffinityGet() is not defined. This

esp_task_wdt_init() API
- Add a set of dedicate TWDT unit tests
- Updates the TWDT example
This commit moidifies the TWDT as follows:
- Adds a feature to allows subscribing arbitrary users to the TWDT
- Changes esp_task_wdt_init() API to accept configuration structure
- Changes esp_task_wdt_init() and esp_task_wdt_deinit() to subscribe/unsubscribe
idle tasks of various cores.
- Adds support for SMP FreeRTOS idle tasks
- Updates startup code TWDT initialization
- Updates API documentation
This commit refactors the task watchdog as follows:
- Renamed variables, types, and functions
- Replaced manual linked list implementation with SLIST()
- Moved calloc()/free() calls out of critical sections
- Shortened ISR critical sections
- Updated API description
- Updated code formatting

Some components were including esp_timer.h without declaring a
dependency on esp_timer component. This used to work due to a
transitive public dependency on esp_timer from freertos component.
Add explicit dependencies where needed.
Also some source files were using esp_timer functions without
including the header file. This used to work because esp_timer.h was
included from freertos port header file. This commit adds esp_timer.h
includes where needed.
Moved the following kconfig options out of the target component:
* CONFIG_ESP*_DEFAULT_CPU_FREQ* -> esp_system
* ESP*_REV_MIN -> esp_hw_support
* ESP*_TIME_SYSCALL -> newlib
* ESP*_RTC_* -> esp_hw_support
Where applicable these target specific konfig names were merged into
a single common config, e.g;
CONFIG_ESP*_DEFAULT_CPU_FREQ -> CONFIG_ESP_DEFAULT_CPU_FREQ_MHZ

IDF FreeRTOS uses vTaskSuspendAll()/xTaskResumeAll() to stop preemption
on a particular core. However, those functions behave differently in FreeRTOS SMP.
This commit replaces all calls of vTaskSuspendAll()/xTaskResumeAll() with
vTaskPreemptionDisable()/vTaskPreemptionEnable() when compiling with SMP FreeRTOS.
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.
If a windowoverflow8 happened after changing the SP, the exception handler would look for
the extra save area by looking at the previous frame's SP. This SP would be a garbage value
and could cause the windowoverflow exception to write to invalid memory ares.

* ESP32_X_BROWNOUT_* -> esp_system
* ESP32_X_DEBUG_OCDAWARE -> esp_system
* APP_NO_BLOBS -> build type (main kconfig)

- 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.

peripheral enable/disable usually should be managed by driver itself,
so make it as espressif private APIs, not recommended for user to use it
in application code.
However, if user want to re-write the driver or ports to other platform,
this is still possible by including the header in this way:
"esp_private/peripheral_ctrl.h"
esp_restart()/panic_restart() never resets the Digital system (so far required only by the Memprot feature) as there's a typo in the corresponding #define:
it checks CONFIG_ESP_SYSTEM_CONFIG_MEMPROT_FEATURE instead of CONFIG_ESP_SYSTEM_MEMPROT_FEATURE.
Issue fixed.

In 4972605, high-level interrupt handler hook was renamed from
ld_include_highint_hdl to ld_include_panic_highint_hdl. However the

This commit removes the following critical nested macros as follows:
- portENTER_CRITICAL_NESTED()
- portEXIT_CRITICAL_NESTED()
They are replaced with portSET_INTERRUPT_MASK_FROM_ISR() and
portCLEAR_INTERRUPT_MASK_FROM_ISR() which are the proper FreeRTOS interfaces.
Created a portmacro_deprecated.h for each port to contain deprecated API
that were originally from portmacro.h
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.
As branches/jumps on Xtensa have a maximum range for the destination, it is
unsafe to refer to a label to another compilation unit in a branch/jump instruction.
The labels have been replaced by absolute addresses.
Clang warns that the original code wouldn't have any effect:
warning: indirection of non-volatile null pointer will be deleted,
not trap [-Wnull-dereference]
note: consider using __builtin_trap() or qualifying pointer
with 'volatile'
__builtin_trap translates to 'break 1, 15' instruction on Xtensa,
which might be okay in this case. However to absolutely certainly not
break anything for GCC builds, add 'volatile' instead.

Level 4 interrupt has a chance of preempting a window overflow or underflow exception.
Therefore it is not possible to use standard context save functions,
as the SP on entry to Level 4 interrupt may be invalid (e.g. in WindowUnderflow4).
Instead, mask window overflows and save the entire general purpose register file,
plus some of the special registers.
Then clear WindowStart, allowing the C handler to execute without spilling the old windows.
On exit from the interrupt handler, do everything in reverse.

PMS aware chips require prefetch padding size for instruction fetch, or
some memory alignment considerations. These settings are now exposed
through kconfig options (hidden) and used through common ld template.

Add Kconfig option SPIRAM_ALLOW_NOINIT_EXTERNAL_MEMORY
When enabled, a new linker script rule (from esp32.extram.noinit.ld)
places any variables in the .ext_ram.noinit section in SPIRAM.
This section is exempted from the startup SPIRAM memory test and is
not zero-initialized or added to the malloc pool, making it usable
for noinit variables that persist across reset.
The EXT_RAM_NOINIT_ATTR macro places variables in this section.
IRAM section didn't contain sufficient padding for possible CPU instruction prefetch,
ie instruction fetch could happen in DRAM section which is prohibited by the Memprot module.
This is fixed by adding 16B to the end of IRAM section in LD script (C3 CPU prefetch buffer depth is 4 words)

table (missing DWARF information).
Fix a bug occuring when parsing backtraces originated from abort().
Fix build missing dependencies issue.
Add .eh_frame and .eh_frame_hdr sections to the binary (can be

when a panic occurs. Their DWARF instructions are decoded and
executed at runtime, to retrieve the whole backtrace. This
parser has been tested on both RISC-V and x86 architectures.

- Turned OFF if not set
The application can still force it to be ON by calling
`esp_sleep_pd_config(ESP_PD_DOMAIN_VDDSDIO, ESP_PD_OPTION_ON);`
