ESP-WROVER-KIT factory firmware

[RobinC]

I've been playing with the new wrover kit and want to install some of the test projects. Before doing that, I wanted to make sure I could get back to the factory image functionality. I don't see the factory software (display tests and temp screen) in the current code on github.

Is the factory firmware available somewhere?

Hi RobinC,

We haven't shipped the source for that demo program yet, but it (or something very similar) will be available as an example in esp-idf.

If you want to back it up for now, you can run "esptool.py read_flash 0 0x300000 wrover_firmware.bin"

And use "esptool.py write_flash 0 wrover_firmware.bin" to write it back.

Too late... Did anyone save the factory firmware available for download? I already nuked mine...

since my wrover kit is stuck
I would need the default bins so i can use the esp_falsh_tool to make factory reset

[RobinC]

Send a PM and I'll send a link. Espressif may not like publishing it publicly...

Still no sign of the default code, or similar example?

I too am looking for the Stock Code for the WROVER Kit v4.1
Any help is appreciated. Won't let me post a PM...
Thanks

Hi am very newby with ESP-IDF. I just got my ESP-WROVER, could you help back up the factory firmware?

Where exactly do I need to run "esptool.py read_flash 0 0x300000 wrover_firmware.bin"?
I cannot find any esptool.py

I am using the stable version

Code: Select all

%userprofile%\esp\Factory_Firmware>esptool.py read_flash 0 0x300000 wrover_firmware.bin
'esptool.py' is not recognized as an internal or external command,
operable program or batch file.

I also tried to run python.exe from %userprofile%\.espressif\python_env\idf4.0_py3.6_env\Scripts

It seems I was simply missing esptool.py. Weird that it was not installed along with ESP-IDF.

Do we know if that demo program is available in examples yet?
I couldn't find it. It would be nice to have the code as well.

I realize this thread is old, but...I believe what you're looking for can be found in:
{esp-idf}\examples\peripherals\spi_master\lcd

I loaded it and got back the fancy picture on the LCD.

EDIT: I just realized that this isn't exactly the same code; it doesn't blink the RGB LED.
