SD卡读写的问题

lzw_happy · 发表于 2010-9-16 10:52:02

TQ24403.5寸开发板。用4G以上的SD卡或者U盘加载过后读/mnt/udisk 和/mnt/sd 后ls显示为空。pc机下面u盘可识别，开发板不能加载是什么原因？

你插入SD卡和U盘后，串口信息呢？

你启动系统后，把SD 卡，或者U盘插到板子上，会有串口信息。
就那些可以了，这个读得累死我。

哈哈已经解决了
加载4G的sd卡在串口信息里显示

PandaReader       audio_play_list.lml
就搞定了
主要是dev默认加载的设备名称发生了变化，重新mount就可以了
