WiFi starts and joins on internal RAM: ~42 KB the first time, ~25 KB after, more for WPA. Free internal RAM had shrunk to ~20 KB after opening the map (the tile decoder's 12 KB stack, the 32 KB I-cache, the DMA draw buffers, UI statics), so a scan failed at once (esp_wifi_init: no memory) and a join during a tile download timed out (AUTH_EXPIRE). - ESP-IDF: CONFIG_SPIRAM_ALLOW_BSS_SEG_EXTERNAL_MEMORY, and the esp_timer task stack 8 -> 4 KB (it uses ~0.4 KB). Rebuild the framework libs: pio run -e Wio_Tracker_L2_idf_libs. - PSRAM_BSS (EXT_RAM_BSS_ATTR) on the UI's big statics: QR codes, map state, charts, lists. .dram0.bss 115 -> 66 KB. - The tile decoder's and fetcher's task stacks in PSRAM. Free internal RAM, idle: 48 -> 105 KB; WiFi up: 57 KB, 29 KB at the lowest while downloading tiles. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
