eyeguy Posted February 10, 2021 Share Posted February 10, 2021 I'm investigating ways to solve a provisioning problems I have that requires configuring a "personality" (persisted state) on a ESP32 platform. I'd like to understand if it may be possible to hardware hack the Bash Bunny (or something else) to use as a compact and portable means for the following two use cases: Use case 1: Configuring a "personality" onto the ESP32 device plug in a USB (something) to the USB connector on a ESP32 board and have power supplied to the ESP32 by the (something) The ESP32 boots up and the bootstrapper/bootloader recognizes a USB flash drive implemented by the (something). The ESP32 bootstrapper/bootloader looks for and discovers a particular file name on the USB flash drive, and then burns the contents of the file ("personality" data) into flash memory within the ESP32 controller. Ideally the "personality" could be selected by a switch on the (something). Use case 2: Configuring a new code image onto the ESP32 device plug in a USB (something) to the USB connector on a ESP32 board and have power supplied to the ESP32 by the (something) An application running on the (something) microprocessor downloads a new bootable image and causes it to be persisted on the ESP32 device. Ideally the "deploy code image" mode could be selected by a switch on the (something). Perhaps the same (something) as in use case 1, but not required. From what I understand so far, the Bash Bunny is not self-powered and does not supply power over USB. Seems like there would be need for a hardware hack or addition of some other power-supplying device into the mix. I sincerely appreciate your thoughts and insights. BTW, this effort is in support of provisioning wearables onboard the TechnoGecko electric autonomous mutant vehicle: https://www.technogecko.org/ .
