Hi.
I have developed some professional products that uses the ESP-01 module, and now I want to update their firmware to continue our tests before start to sell the products.

The flash memory chip of the board is 8Mbit (25Q80A) and the crystal is 26MHz.

What I tried to do?

(1) I entered on this page (wiki.ai-thinker.com/esp8266/sdk) and downloaded the "factory AT firmware" (ai-thinker_esp8266_at_firmware_dout_v1.5.4.1-a_20171130.rar).

(2) Then entered on this page (wiki.ai-thinker.com/esp_download) and downloaded the "Download Tool" (flash_download_tools_v3.6.6.zip)

(3) Then opened the Flash Download Tool and did as the picture below shows, but when I try to download the firmware the status shows "ERROR" message.


Also, I tried the same but with "DOUT" marked as SPI option and the same error occurred.

What is wrong, how to do firmware download correctly? I need to do this...
The other pictures shows what my modules respond when I send AT+GMR command to them.


Regards,
Jeferson.
