# Boot-Linux-ESP32S3-Playground
This is a playground for Boot Linux on ESP32-S3.
Example kernel and rootfs images built from the above [wiki sources](http://wiki.osll.ru/doku.php/etc:users:jcmvbkbc:linux-xtensa:esp32s3) as well as a [toolchain archive](http://wiki.osll.ru/doku.php/etc:users:jcmvbkbc:linux-xtensa:esp32s3)
used hardware in this case: ESP32-S3-N8R8 DevKitC-1 from [Espressif](http://espressif.eu) ( Octal-pSRAM )
