RISC-V Bytes: Exploring a Custom ESP32 Bootloader · Daniel Mangum
I recently acquired an ESP32-C3-DevKitC-02 module, and, as I tend to do, jumped right into reading about how the system boots and how the (pretty good!) tooling Espressif offers works. We have typically used QEMU in the RISC-V Bytes series, but getting our hands on physical hardware starts to make things feel a bit more real. In this first post on the ESP32, we’ll do some basic setup and look at a simple custom bootloader.
