Hello.
I am using FX3 - CYUSB3035. It works as the "cyfx3s_fatfs" example, but an error occurs.
* Using the example
* Block diagram of structure
* Schematic
* Error message
? : CY_U3P_ERROR_INVALID_UNIT, /**< Non-existent storage partition selected for transfer. */
I think it's the error message.
Other than the "ls" command, it doesn't work.
Please check if there is any problem with F/W & H/W
Thank you for reply.
I kown I have to use SD3.0.
J1 is SD Card connector. I'm using the SD card(SD3.0) below.

Error code is "? : CY_U3P_ERROR_INVALID_UNIT"
"// No use" part was corrected. And S0 is not use.
S0 ports are connected the controller. But it's not use.
