ESP32 Forum

I am trying to flash the AT command set onto my Sparkfun ESP32 Thing.

When I boot after flashing I get the following messages
[0;32mI (32) boot: compile time 07:53:05[0m
[0;32mI (49) boot: Enabling RNG early entropy source...[0m
[0;32mI (50) boot: SPI Speed : 40MHz[0m

[0;31mE (117) boot: Failed to verify partition table[0m
[0;31mE (133) boot: load partition table error![0m
user code done

Note that it is showing a SPI Flash Size of 2MB when I know I have an 8MB flash. The Flash downloader properly identifies
it as an 8MB.

Why does the bootload thing I have a smaller Flash?
How can I resolve this error?

What method/command are you using to flash the firmware?

I am using the Flash Download Tool V3.6.3.
I have attached a screenshot of my setup

The address of the esp-at.bin file looks suspicious. I normally expect to see the application loaded at 0x10000 and not 0x100000 as you have described.
