ESP32-CAM not taking firmware file (lemariva)

Post by AwesomeCronk » Fri Nov 27, 2020 1:36 pm

I have three ESP32-CAM devices that I am trying to get set up. The first one has been set up using a fork of uPython at https://github.com/lemariva/micropython-camera-driver written by lemariva that allows access to the onboard camera. As of now, I have the first one running, but the second one refuses to save the firmware file. When I reboot the device after running erase_flash and look at it with a serial terminal, I get this output:

Code: Select all

rst:0x1 (POWERON_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2))

waiting for download
After running write_flash with the specified binary file (found under the firmware folder in lemariva's repository), I switch to the serial terminal, reboot the device, and get the same output as before I ran write_flash. What is going on here?

I am using esptool v2.8 and the last commit on the firmware I am using was commit 8c91c6801cc6250b2d285526d61f20a6d30c70b2.

Solution is to unjumper gpio0 and ground after flashing it. Facepalm moment for sure.
