ESP chip Swiss knife tool in a browser
Hello,
I wanted to share my project that I've been working on that is aimed for debugging and flashing everything around the esp chip from the browser only without anything to install. I got frustrated with the current tech that for a lot of basic things esp-idf is needed while I don't have my regular device at hand. There are couple of other projects allowing to flash the board from browser or open a terminal but most of them are very basic and not sufficient to do something more advanced. I got into the internals and realised the tech is ready (Webserial api, webassembly and browser support) and exists but there is no tool to leverage it so I built the ESP Swiss knife tool.
All of this runs in a browser as a static website with no installation (browser must support Webserial, recommended choice is chrome/edge)
Here is a quick rundown of features:
- flash and chip identification
- read and write memory (in bootloader mode) interactive terminal
- inspect security status of efuses and configuration (secure boot) read and browser partition table flash any partition or whole chip, verify on flash, sanity check for alignment and compatibility, dump chip/partition or edit any flash data via builtin hexviewer
- inspect bootloader details
- edit otadata status, reflash apps and change their ota status
- browse and modify NVS keys in nvs partition
- browse and modify with full file browser for supported FS partition types (littlefs, spiffs, fat32) read and decode coredumps directly in browser
The tool is available for free at https://esp.sourcecode.ai . Please share any feedback or ideas for improvements. Thank you guys for trying and I hope this helps you in debugging as much as it does me on daily basis!
