I want to update the firmware to ESP8266 RTOS SDK V1.5.0 which I have downloaded from Github.
Also got flash_download_tools_v3.4.4 from espressif.
Got no idea what files to flash to what addresses.
I can find 3 bin files in the SDK I downloaded which are:
blank.bin
boot_v1.6.bin
esp_init_data_default.bin
Thanks
