This another bootloader, originally based off rboot, but has the following notable features:
- Works with applications created from latest ESP8266 SDK, which have an entrypoint in ROM. Applications with IRAM entrypoints (e.g. Arduino) still work too.
- Includes build date, version information and description in the application header, so you can can see the details of the applications stored in flash. This is particularly helpful when managing applications and selecting the boot index.
- Uses 0 bytes of stack space. Before starting the application, the stack is reset so there's no wasted DRAM.
- Similar to rboot, zboot allows the use of the entire flash part for OTA updates and multiple applications stored in flash.
A generic build environment for microcontroller projects. The main goal of the project is to reduce or eliminate copying code when building microcontroller projects. micro-builder's library management provides some of the same features of the Arduino IDE, but doesn't constrain the user to the Arduino IDE. micro-builder uses zboot by default for ESP8266 targets.
These projects (and other associated projects) were created for a few specific needs, but I'm looking to see if there's any other interest. Please share any thoughts.
