# ESP32 Platform Configuration
|
|
# Included by all ESP32-based boards (XIAO ESP32-C3, XIAO ESP32-C6, etc.)
|
|
# Only contains ESP32-specific settings — common BLE/Storage/Input is in zephcore_common.conf
|
|
#
|
|
# Include order: prj.conf → zephcore_common.conf → esp32_common.conf → <board>/board.conf
|
|
|
|
# ========== BLE: ESP32-specific controller settings ==========
|
|
# DLE managed internally by Espressif blob — no CONFIG_BT_CTLR_DATA_LENGTH_MAX
|
|
# TX power managed internally by Espressif blob — no CONFIG_BT_CTLR_TX_PWR_*
|
|
|
|
# BLE thread stacks — ESP32 software BLE controller needs larger stacks
|
|
CONFIG_BT_TX_PROCESSOR_STACK_SIZE=2048
|
|
|
|
# ========== Heap ==========
|
|
# ESP32 BLE stack requires larger heap (override zephcore_common 2KB default)
|
|
CONFIG_HEAP_MEM_POOL_SIZE=32768
|
|
|
|
# ========== Flash ==========
|
|
# 4MB is standard for XIAO/LilyGo RISC-V boards.
|
|
# Station G2 (16MB) overrides in board.conf.
|
|
CONFIG_ESPTOOLPY_FLASHSIZE_4MB=y
|
|
|
|
# ========== Debug ==========
|
|
# CONFIG_ASSERT disabled for ESP32: Espressif's closed-source BLE controller
|
|
# blob leaves IRQs in a state that triggers false "Context switching while
|
|
# holding lock!" assertions in kswap.h. The BLE stack works correctly — the
|
|
# blob manages its own IRQ state internally. nRF52/nRF54L boards keep asserts
|
|
# via their platform configs; ESP32 relies on logging for debug.
|
|
# CONFIG_ASSERT=n (Zephyr default)
