commit 9f89c1c2a698c560182a331dc86019c6af690f05 Author: Marcio Ribeiro <[email protected]> AuthorDate: Thu Sep 3 15:25:23 2026 -0300 boards/risc-v/esp32c2/esp8684-devkitm: add ESP8684-DevKitM board Add NSH bringup for the Espressif ESP8684-DevKitM. The nsh defconfig uses a 26 MHz XTAL, 4 MB flash, and debug features for the MINI-1 module.
