回复: USB不能接U盘

Hi @geyuer123 

板子是在host模式吗?如果不是,试试

1>petalinux-config -c kernel
Device Drivers ---> Input device support ---> <*> Event interface
2>petalinux-build

Thanks
Simon

@geyuer123 

可能是相关驱动配置不太正确,

1. 换个U盘试试;

2. lsusb, 打印输出是怎样?

3. 是MPSOC还是zynq7000? USB2.0还是3.0?如果是USB3.0在vivado中有没有勾选正确?

4. 参考下https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841729/Zynq+Ultrascale+MPSOC+Linux+USB+device+driver对比下petalinux配置过程是否正确。

 

供参考~
