I'm trying to update my ESP-01 to firmware v1.7.4. I have the ESP Flash Download Tool and the device below:


Here's my device info:


My problem is I don't know what addresses to load each firmware file (there are several but blank.bin is loaded more than once)

I've tried the examples in the Quick Start Guide but when I return the switch on the dongle to UART mode, and fire up my terminal (TeraTerm) all I get is a never-ending stream of garbage. Can anyone help me update the firmware? At least let me know the addresses for a 32Mbit device. Are the addresses the same as the 32Mbit-C1? If so then there's something else wrong since I tried those and still got the garbage.

that sounds like you don't have the correct baud rate on your terminal - what do you have it set to?

Hi, I usually use the ESP Flash download tool in order to update it. Regarding hardware, I used to work with arduino board.

No i mean your TeraTerm baud rate is not correct - the ESP is sending you data and information but it's garbled due to the wrong baud rate
