DM385使用uclibc交叉编译器编译

请问TI能够提供使用uclibc交叉编译的交叉编译工具吗？

    详细说一下，由于希望精简DM385的文件系统，官方的开发包里仅提供了使用glibc编译的交叉编译工具，编译出来的文件系统精简后也要17M左右，其实主要还是glibc相关的库文件比较大，我使用uclibc编译了一个交叉编译工具，但是编译后的内核无法启动，出现很多错误。

    uclibc和glibc的差别还是蛮大的，用uclibc链内核，风险太大，最精简的文件系统应该是没有17M这么大的，可以进一步精简，去掉一些不需要的库文件和静态库文件，还有个办法就是可以考虑下ramdisk

    uclibc的交叉编译工具HK在用，我在他的产品的打印信息中确认过，使用的是uclibc。风险是会有，但是理论上是可行的，只是需要时间来验证。使用glibc的文件系统我已经精简过了，17M已经很小了，整个系统要想使用16M的flash，文件系统至少要控制在12M左右，最好是10M左右。

    内核启动失败的问题是由于编译器编译选项中没有使用soft-float导致，之前使用的是NEON，选择soft-float后重新编译内核、uboot，之前uboot第二阶段无法启动的问题也解决了，内核的问题也没有了，现在就差文件系统引导起来就可以测试稳定性了。有相同需求的朋友可以参考一下。
