sdkconfig.defaults.esp32s3

# ESP32-S3 family common defaults — shared between the CoreS3 (M5/Takao base)
# and AtomS3R (Atomic ECHO BASE) builds. Per-board overrides go in
# sdkconfig.defaults.cores3 / sdkconfig.defaults.atoms3r (chained last). PSRAM
# mode in particular is per-board because it cannot be switched at runtime
# (the bootloader needs to know Quad vs Octal at link time).

CONFIG_IDF_TARGET="esp32s3"
# Flash size is per-board (CoreS3 16 MB / AtomS3R 8 MB) — set in the
# sdkconfig.defaults.<board> overlay that's chained after this file. A
# mismatch makes the SPI flash size header reject boot.

# Both boards carry 8 MB PSRAM; the host-side malloc behaviour is identical.
# The wire mode (Quad vs Octal) and clock speed are the per-board overrides.

# NOTE: SPIRAM_MALLOC_ALWAYSINTERNAL is intentionally NOT set here. The
# value lives in the common sdkconfig.defaults (=1024) — this per-target
# file is loaded *after* it in the SDKCONFIG_DEFAULTS chain, so setting it
# here would silently override the common value. A stale 16384 here was
# exactly that bug: local builds (whose persisted sdkconfig had 1024)
# worked, but fresh CI builds got 16384 and the esp-aes DMA alloc failed
# during TLS reconnects. Keep memory tuning in the common file only.

# Default console on the on-board USB-Serial-JTAG.
