Please use Espressif Flash Download Tool !!!

[tomotomo]

I tried to use ESP_DOWNLOAD_TOOL_V2.4.exe for update firmware.
I downloaded AT_v0.51_on_ESP8266_NONOS_SDK_V1.5.0.zip and read readme.txt.
readme.txt says

Flash size 32Mbit-C1: 1024KB+1024KB
boot_v1.2+.bin 0x00000
user1.2048.new.5.bin 0x01000
esp_init_data_default.bin 0x3fc000 (optional)
blank.bin 0xfe000 & 0x3fe000

but I could not find 'boot_v1.2+.bin'.
Where can i get 'boot_v1.2+.bin' ?

I think "+" means version 1.2 or higher. As example boot version 1.4+ means (also) boot_v1.4(b1).bin.

You can use boot_v1.2.bin but according the fact that newer version (1.2+) is supported, you should rather use the latest boot version which is boot_v1.4(b1).bin at the moment.

hi,

what is the alternative in case we do not have a windows os?

I tried to use the provided python tool but it requires py-exec that is only provided for windows

How to erase the whole external Flash using this Flash download tool?

I think I downloaded to a wrong address, then cause the whole module dead, ESP-12 module always ON red and blue leds. So I need to erase all to do re-flash.
