Local Shell is a new web-based tool that talks to Zephyr devices using Simple Management Protocol (SMP) over Web Serial APIs. This is an easy way to communicate with devices through the browser and mirrors capabilities from tools like mcumgr and smpmgr.
Golioth firmware engineer Mike Szczys walks through debugging the MCUboot bootloader using gdb. This is a slightly different task than normal Zephyr debugging, but can help to find tricky bugs.
Golioth APIs enables hundreds of connected hardware devices to do firmware updates. Espressif's ESP32 now joins that group with their port of MCUboot to their platform. This post shows how to enable this open source bootloader.
