I follow the guide "ESP32_Certification_and_Test_Guide__EN.pdf" to put the ESP32 into FCC Certification mode. After flashing the module then rebooting it, it is stuck into a reboot loop :
The second block is repeated infinitely.rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

My hardware is an ESP32-DevKitC and I flashed the module with ESP32 DOWNLOAD TOOL V3.6.3
Anyone get an idea ?
