-`fip.bin` 是一个打包后生成的 bin 文件，包含了 `fsbl`、`uboot` 以及小核的内核镜像文件 `rtthread.bin`。但注意 BSP `c906_little` 构建生成的 `fip.bin` 中的 `fsbl`、`uboot` 这些文件都是 RISC-V 的，所以我们并不能把 BSP `c906_little` 构建生成的 `fip.bin` 直接拿来用于引导启动 ARM 大核。我们这一步只是确保先基于 BSP `c906_little` 做出最新的小核版本 `rtthread.bin`。在下一步构建大核的过程中我们会重新打包更新并生成新的 `fip.bin`，而在重新打包过程中我们需要这个小核的 `rtthread.bin`。
