Primary Git Repository for the Zephyr Project. Zephyr is a new generation, scalable, optimized, secure RTOS for multiple hardware architectures.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on resource-constrained systems: from simple embedded environmental sensors and LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M, Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of supported boards.

zephyr's Issues

ESP32 bootloader.bin not found when flashing

Describe the bug
Hi!
I was trying out the WiFi support for ESP32 and encountered the following issue: each time I build an app and try to flash it I get an error pointing that no bootloader.bin is present in the build (no partitions file is generated as well). Tried the CONFIG_BOOTLOADER_ESP_IDF=y option as well, still no bootloader is being built.

To Reproduce

1. west build -b esp32 -s samples/net/dhcpv4_client/
2. west flash --esp-device [device COM port]

Expected behavior
Build and flash the dhcpv4_client app

Impact
Been tackling this one for some time of this week so any help would be much appreciated :) .
