TDA4VM-Q1: uboot中环境变量默认存储到SD卡,如何修改

Part Number: TDA4VM-Q1
Other Parts Discussed in Thread: TDA4VM

您好

     我们在尝试emmc启动TDA4,方法如下:

一、使用sd卡启动UBoot,然后在u-boot 下执行如下操作将boot刷新到emmc boot0分区

二、poweroff,然后设置启动模式为emmc(boot)模式

三、poweron,再次进入UBoot(emmc启动正常),修改环境变量并保存时报错

四、尝试了插入SD,此操作成功。发现saveenv默认保存到SD卡下,SD卡boot分区出现bBoot.env文件

所以问题是如何保存环境变量到默认环境,而不是到SD卡下
