Hi wxie, I can successfully build, compile and flash my LILY ESP32 TTGO V2 with the source on https://github.com/sudomesh/disaster-radio <https://github.com/sudomesh/disaster-radio>. My LILY ESP32 TTGO V2 then gets stuck in a loop of rebooting. The monitor shows this: rst:0x8 (TG1WDT_SYS_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 188777542, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:2 load:0x3fff0030,len:1184 load:0x40078000,len:13132 load:0x40080400,len:3036 entry 0x400805e4 [ 227][E][Preferences.cpp:483] getString(): nvs_get_str len fail: un NOT_FOUND No name saved Got username Got IF setting WiFi Got txPwr setting 17 Got loraFrq setting 915 Got sf setting 9 [ 238][E][Preferences.cpp:503] getBytesLength(): nvs_get_blob len fail: duty NOT_FOUND Got duty setting 0.100000 Got interval setting 10000 Got gps setting 0 Initializing WiFi... --> Started WiFi AP "disaster.radio 6d088758", IP address: 0.0.0.0 Initializing mDNS responder... --> Advertising http://disaster.local <http://disaster.local/> Initializing SPIFFS...

Thanks. I tried building the candidate release and it builds and runs. I get some OLED warning compiling, not sue why? But things seems to work. I also get issues with the SD card. Apart from that all working. Any ideas on the warnings and SD card problems ?
