您好
环境描述：am3352 custom board，sdk：ti-processor-sdk-linux-am335x-evm-05.02.00.10
之前帖子在工程师帮助下（没有eeprom，ddr leveling, mmc1驱动，网口驱动），spl和uboot已经能成功启动，并且通过dhcp把zImage和dtb（设备树应该是和uboot设置匹配的，见输入printenv打印出的环境配置信息）文件传给板子，现在想通过uboot命令让kernel加载到ddr上运行，,uart0接电脑，打印如下：

Kernel编译配置：make tisdk_am335x-evm_defconfig
make menuconfig尝试增加early printk，但是串口没有多的输出，看到这个比较奇怪，printk不能选择uart0，只能选择uart1-3，不知道是不是启动了就是信息打印到别的串口了？但是ssh登录无响应。
恳请技术支持debug方向，网上帖子搜的比较多，对比了ti给出的几种错误，并不能解决，请帮助谢谢！
