Hi Oscar Niño,

Hi Jeremyzhou

Thanks for reply. What it supposse to happen? I mean; I saw a message "host init done" but when I connect the USB device, nothing happened. What it should happen when I connect the USB pendrive? I had tried with almost all examples but nothing happened, maybe I'm doing something wrong. I attach a picture about how I'm connecting the device.

Best regards

Hi Oscar Niño,Fig 1 illustrates the run result, and Fig 2 represents the hardware attaching.
On my site, the usb_host_msd_fatfs demo works well.
In the attachment, it guides the developer how to get started with the demo.
