 # StarFiveTech VisionFive2 SDK
 
-This builds a complete RISC-V cross-compile toolchain for the `StarFiveTech` `JH7110` SoC. It also builds U-boot SPL, U-boot and a flattened image tree (FIT) image with a Opensbi binary, linux kernel, device tree, ramdisk image and rootfs image for the `JH7110 VisionFive2` board. Note this SDK is built with the linux kernel version `6.1`.
