好好一直用着,放假一直插着电没关,近两个多星期回来TF卡启动uboot发现无任何打印信息
怀疑是uboot的问题,用SDFormatter格式化之后重新烧录裸机例程测试,发现灯也点不亮
设置成EMMC启动,测试启动linux后的插拔卡的打印信息,如下:
[ 36.312556] mmc0: card never left busy state
[ 36.316862] mmc0: error -110 whilst initialising SD card
[ 38.432575] mmc0: card never left busy state
[ 38.436883] mmc0: error -110 whilst initialising SD card
[ 40.552551] mmc0: card never left busy state
[ 40.556860] mmc0: error -110 whilst initialising SD card
[ 40.678845] mmc0: Skipping voltage switch
[ 40.706571] mmc0: Skipping voltage switch
[ 40.734039] mmc0: Skipping voltage switch
[ 40.763227] mmc0: Skipping voltage switch
[ 40.788827] mmc0: Skipping voltage switch
拔掉TF卡的信息为
[ 44.425927] mmc0: error -123 whilst initialising SD card
换了其他的TF卡也是这样,有没人遇到过这样的情况,求指导,板子是借同事用的,弄坏了不好交差了
