Hi @Arularasan 

Do you use USB1 or USB0?

There are some USB demo codes under MCUXpresso SDK folder. By default, the demo code is for USB0 (FS USB). If you use USB1, please follow below article to switch to USB1 code:

For HW design, I suggest you refer EVK schematic:

I tested host_msd_fatfs_bm demo with LPC55s69 demo board, it ran well.

While on LPC54018 board, I got the same as yours. I am checking the reason. Will let you know as soon as I find it out.

Thanks,

HI Arularasan 

I tested host_msd_fatfs for both USB0 and USB1. They both work well. 

Please check the jumper setting.

For USB0 (USB FS), board jumper settings are as below

J9 2-3 full speed mode; J10  shunt full speed; J11 2-3, J12 2-3, J13 2-3 , need provide external power through J1.

For USB1 (USB HS), board jumper settings are as below

J9 1-2 high speed mode; J10 open high speed; J11 2-3, J12 2-3, J13 2-3 , need provide external power through J1.

As the default code is for FS USB. To work with HS USB, revise source\usb_host_config.h macro as below :

#define USB_HOST_CONFIG_OHCI (0U)

#define USB_HOST_CONFIG_IP3516HS (1U)

@ZhangJennie thanks for your support.

After modify demo code  macro definition in usb_host_config.h and jumpers to USB1 its working

thank you...
