大家好，最近在使用am335x新版的processor-sdk-linux-am335x-evm-06.03.00.106-Linux 。板子是自制的，使用的是AM3359，1GB DDR3,512MB NandFlash，没有外接TF卡，没有带EEPROM，两路RGMII都使用上了，目前编译的方向是向A335X_SK靠近，使用am335x-evmsk.dtb，目前已经将MLO、u-boot.img、zImage、dtb、ubi（am335x-evm-06.03.00.106-Linux.bin中filesystem文件夹中自带的ubi文件）等按照如下地址烧录到NandFlash中，

请教各位大神，是我的uboot内容不对，还是ubi文件需要重新编译？从网上搜到的信息基本都是按照 Ubifs文件系统的制作和启动.pdf 这个文件制作，但是文件中所说的路径和宏好像都发生了变化，感觉已经不适用了。编译uboot以及linux时都是在根目录下直接用make就可以完成的，但是没有找到ubi的make方式。
并且menuconfig也是按照/board-support/u-boot-2019.01+gitAUTOINC+333c3e72d3-g333c3e72d3/configs/am335x_evm_defconfig 这个文件来执行的，我想关闭了usb ethernet ，关闭了am335x_evm_defconfig里面的相关宏，编译时也会报错。
