default ESP_COREDUMP_ENABLE_TO_NONE
help
Select place to store core dump: flash, uart or none (to disable core dumps generation).
Core dumps to Flash are not available if PSRAM is used for task stacks.
If core dump is configured to be stored in flash and custom partition table is used add
corresponding entry to your CSV. For examples, please see predefined partition table CSV descriptions
in the components/partition_table directory.

depends on ESP_COREDUMP_ENABLE_TO_FLASH
help
When enabled, if any data are found on the flash core dump partition,
they will be checked by calculating their checksum.
config ESP_COREDUMP_ENABLE
bool
default F
help
Enables/disable core dump module.
config ESP_COREDUMP_LOGS
bool "Enable coredump logs for debugging"
depends on ESP_COREDUMP_ENABLE
default y
help
Enable/disable coredump logs. Logs strings from espcoredump component are
placed in DRAM. Disabling these helps to save ~5KB of internal memory.
config ESP_COREDUMP_MAX_TASKS_NUM
int "Maximum number of tasks"
depends on ESP_COREDUMP_ENABLE
default 64
help
Maximum number of tasks snapshots in core dump.
config ESP_COREDUMP_UART_DELAY
int "Delay before print to UART"
depends on ESP_COREDUMP_ENABLE_TO_UART
default 0
help
Config delay (in ms) before printing core dump to UART.
Delay can be interrupted by pressing Enter key.
config ESP_COREDUMP_FLASH_NO_OVERWRITE
bool "Don't overwrite existing core dump"
depends on ESP_COREDUMP_ENABLE_TO_FLASH
default n
help
Don't overwrite an existing core dump already present in flash.
Enable this option to only keep the first of multiple core dumps.
If enabled, the core dump partition must be erased before the first
core dump can be written.
config ESP_COREDUMP_USE_STACK_SIZE
bool
default y if ESP_COREDUMP_ENABLE_TO_FLASH && SPIRAM_ALLOW_STACK_EXTERNAL_MEMORY

help
Force the use of a custom DRAM stack for coredump when Task stacks can be in PSRAM.

help
Size of the memory to be reserved for core dump stack. If 0 core dump process will run on
the stack of crashed task/ISR, otherwise special stack will be allocated.
To ensure that core dump itself will not overflow task/ISR stack set this to the value above 800.
NOTE: It eats DRAM.

Size of the buffer that would be reserved for extracting backtrace info summary.
This buffer will contain the stack dump of the crashed task. This dump is useful in generating backtrace
