Espressif Systems releases a Linux BSP developer preview for ESP32-S31 RISC-V microprocessor

The ESP32-S31 microprocessor is getting Linux support from Espressif Systems. The ESP32-S31 dual-core RISC-V microprocessor was first unveiled in March, two ESP32-S31 development boards followed in May, and mass production was announced a few weeks ago. The new RISC-V chip features an MMU (Memory Management Unit), which makes Linux much easier to handle, and the development boards also come with 16MB PSRAM, so a minimal Linux image is possible. Moving from theory to practice, Espressif Systems has now released a developer preview version of the ESP Linux BSP for ESP32-S31, and some community Linux ports are also in the works (more on that at the end of the article). Let’s focus on the official ESP Linux BSP. The aforementioned repo only contains the image layout and packaging tools used by the ESP32-S31 Buildroot integration, and the core of the project can be found in the esp-buildroot-external repo with ESP32-S31 NOR boot [...]
