mongoose-os

there is a community driven fork of crosstools-ng which in turn is based on a gcc fork made by a tensilica/cadence employee (jcmvbkbc). both gcc and gdb are ported to the call0 calling convention (no register windows on lx106). it's quite a mess but it's getting better. we (Cesanta) packaged and cleaned up the build environment: https://github.com/cesanta/mongoose-iot you can use our docker based toolchain. It contains a few patches (malloc, stdio, moved all text sections to flash, ...), a gdb stub and serial crash dumper, working OTA solution and a sensible event driven networking API (based on the good old mongoose web server) for those that just can't wrap their heads around espcon . please take a look. the embedded JavaScript interpreter thing can be disabled if not necessary

To anybody interested in ESP8266 and JavaScript, shameless plug: https://github.com/cesanta/mongoose-iot It can also be used as a replacement SDK for C development. In addition to the stock ESP8266 SDK it offers a filesystem, configuration infrastructure, async networking library (using the github.com/cesanta/mongoose networking library), OTA update support, coredumps, easy to use toolchain based on docker, improved (faster) flashing tool. And you can also enable the JavaScript scripting engine and script your firmware. We're also supporting other platforms such as the cc3200 so it will enable you to easily change the target; some platforms are good for prototyping, some are better for production; often it's impossible to choose wisely at the beginning so it's nice to not require a full rewrite of your logic.

shameless plug: portable JavaScript+C programming environment for esp8266/esp32/cc3200/RPi https://github.com/cesanta/smart.js. Supports over the air updates (OTA) both and rapid development and updating your device fleet.

Have a look at our GitHub page: https://github.com/cesanta/smart.js Smart.js is open source and works with ESP8266, CC3200 and POSIX.

Shameless plug: Embedded JavaScript VM, ported to ESP8266 port https://github.com/cesanta/smart.js

I think the key contribution outlined in the post is the heap profiler tool that allows you to figure out whether you need a different allocator for your needs. The tool can be found at https://github.com/cesanta/smart.js/tree/master/tools/heaplo... If anybody knows other similar open source tooling, please share!
