In the last two posts in the RISC-V Bytes series we have looked at a bootloader for the ESP32-C3, then built a Zephyr application that was loaded by it. In this post we’ll take a closer look at that “Hello, World” application, diving into what happens prior to printing our message to the UART console. Note: all analysis and code samples used in this post correspond to the v3.3.0 release of Zephyr.
