TI中文支持网自己做的3358板子，使用ddr3（和BBB一样），nand启动；
使用sdk8.0的uboot和kernel，修改了uboot中的read_eeprom、sdram_init中config_ddr使用和BBB一样的参数。
在启动时，串口信息如下：

卡在这里不动。
请问下，这是有哪里没有修改到吗？（使用开源社区的BBB的uboot和kernel启动能够正常，但开源社区的UBI挂载有问题）
谢谢！
HG：
应该还是参数不对， kernel根本就没有启动
Eggsy Pang：
进入uboot命令界面，输入printenv，截图看一下传参
QingKai Ji1：
回复 Eggsy Pang:
1、uboot参数不对的话，kernel会起不来吗？（我理解是kernel起来后运行不正常）
2、uboot参数如下：
