esp-idf/tools/test_idf_monitor/Makefile

# The purpose of this Makefile is to build dummy ELF files required to run idf_monitor tests.

# Make sure the toolchains are in the PATH:
PREFIX_XTENSA ?= xtensa-esp32-elf-
PREFIX_RISCV ?= riscv32-esp-elf-

PROG_XTENSA := dummy_xtensa.elf
PROG_RISCV := dummy_riscv.elf

# This actually depends on the value of portUSING_MPU_WRAPPERS.
# I.e. ESP32-S2 would also have TASK_NAME_OFFSET=52 since portUSING_MPU_WRAPPERS is 0.
CPPFLAGS_XTENSA := -DTASK_NAME_OFFSET=56
CPPFLAGS_RISCV := -DTASK_NAME_OFFSET=52
