uboot(1.1.4) kernel (2.6.17.13) busybox(1.21)移植

litroncn

近段时间工作是自己制作编译个arm-linux-gcc-4.0.3至今使用正常,移植了uboot,我的板子本来也是用的uboot但公司不给uboot源码,我不知道这样算不算违反GPL协议.1. 制作交叉编译工具arm-linux-gcc (4.0.3)顺便也做了支持软件浮点,不过在uboot上编译通过,下载uboot后在板子上不能通过串口打印信息,但编译内核就没有问题,到现在还没有搞定,不过可能是浮点两中标准混在一起使用了.2. 移植uboot3. 移植内核2.6.17(包括部分主要驱动)4. 制作文件系统busybox(1.2.1)启动信息如下:U-Boot 1.1.4 (Sep  4 2006 -
