# Environment Setup
Setup the development environment for Sigmastar SSD202

## Download SDK

```shell
https://gitee.com/qiming-zhixian/ssd20x-images-open 	#Images
https://gitee.com/qiming-zhixian/ssd20x-uboot-open 	#uboot
https://gitee.com/qiming-zhixian/ssd20x-kernel-open 	#kernel
https://gitee.com/qiming-zhixian/ssd20x-rootfs-open 	#rootfs
https://gitee.com/qiming-zhixian/ssd2xx-openwrt-open #openwrt
```

- `ssd20x-images-open`is the system images,and can be used for the production of master chips, USB disk/SD card upgrade images, partition size adjustment, etc.;
- The compiled binary files `ssd20x-uboot-open, ssd20x-kernel-open, ssd20x-rootfs-open` need to be copied and replaced with the corresponding files in `ssd20x-images-open`, and some of them require secondary processing before they can take effect.
