转——Zedboard实现Linux

折腾了近半个月了，终于在Zedboard实现Linux的畅通，起初是使用Zedboard自带的SD卡，自行编译了uboot2018.1版本，顺利运行后，卡在了devicetree，研究了1周多，终于搞明白了怎么生成devicetree，随后又卡在uramdisk.image.gz，提示不能读取，这样Linux内核就不能运行，其实可以在uboot中把uramdisk.image.gz这项暂时去掉的，但是就不完整了，于是在网上找到了编译uramdisk.image.gz的网页，研究了，实现了uramdisk.image.gz的制作，可是又出现问题了，自带的sd卡的boot空间有限，只有15m，没办法，又开始研究sd的制作，折腾了近2天，终于实现了sd的自制，特意在boot分区留足了空间300m，再次把之前编译好的文件都拷贝到SD卡，奇迹出现了，运行正常，终于可以长出一口气了。
