The framework libs are rebuilt for the L2's own ESP-IDF options (solo/wio-tracker-l2/idf/sdkconfig): a 32 KB instruction cache and 64-byte data cache lines make frames ~35% faster (map 45 -> 30 ms, settings ~36 -> 22 ms). mbedTLS and the NimBLE host allocate in PSRAM, so internal RAM ends up with more free than before (103 KB, largest block 57 KB; was 89.6 / 45). Wio_Tracker_L2_idf_libs does the rebuild; it has to run before the firmware env, also in CI. idf/arduino_tinyusb gives the rebuild the TinyUSB options and the framework's prebuilt library, which it would otherwise lose.

# ESP-IDF options for the L2's LVGL firmware, over the Arduino framework's own

# The reason for all this: a 32 KB instruction cache (the framework ships

# 16 KB) and 64-byte data cache lines. LVGL runs from flash and draws into
|

# PSRAM; frames draw ~35% faster. Costs 16 KB internal RAM.
