Espressif ESP32-S2 User Manual

Chapter 2. API Reference
The ESP32S2 contains a feature which allows you to trace the execution path the processor has taken
through the program. This is stored in a chunk of 32K (16K for single-processor) of memory that can’
t be used for general purposes anymore. Disable this if you do not know what this is.
Default value:
• No (disabled)
CONFIG_ESP32S2_ULP_COPROC_ENABLED
Enable Ultra Low Power (ULP) Coprocessor
Found in: Component config > ESP32S2-specific
Set to ‘y’if you plan to load a firmware for the coprocessor.
If this option is enabled, further coprocessor configuration will appear in the Components menu.
Default value:
• No (disabled)
CONFIG_ESP32S2_ULP_COPROC_RESERVE_MEM
RTC slow memory reserved for coprocessor
Found in: Component config > ESP32S2-specific > CONFIG_ESP32S2_ULP_COPROC_ENABLED
Bytes of memory to reserve for ULP coprocessor firmware & data.
Data is reserved at the beginning of RTC slow memory.
Range:
• from 32 to 8176 if CONFIG_ESP32S2_ULP_COPROC_ENABLED
• from 0 to 0 if CONFIG_ESP32S2_ULP_COPROC_ENABLED
Default value:
• 2048 if CONFIG_ESP32S2_ULP_COPROC_ENABLED
• 0 if CONFIG_ESP32S2_ULP_COPROC_ENABLED
CONFIG_ESP32S2_ULP_COPROC_RISCV
Enable RISC-V as ULP coprocessor
Found in: Component config > ESP32S2-specific > CONFIG_ESP32S2_ULP_COPROC_ENABLED
Set this to y to use the RISC-V coprocessor instead of the FSM-ULP.
Default value:
• No (disabled) if CONFIG_ESP32S2_ULP_COPROC_ENABLED
CONFIG_ESP32S2_DEBUG_OCDAWARE
Make exception and panic handlers JTAG/OCD aware
Found in: Component config > ESP32S2-specific
