LPC55S69 USB host doesn't work.

 

SW: SDK example(usb_host_msd_fatfs_bm).

HW: LPC55S69-EVK

 

HW setting USB0 FS host is as below.

Jumper J6 set to  FS.

Jumper J7 closed.

Connect P5 to power.

Connect device on P10 full speed micro AB connector

 

Then  make sure the following defines in usb_host_config.h  must be set like this

#define USB_HOST_CONFIG_KHCI (0U)

#define USB_HOST_CONFIG_EHCI (0U)

#define USB_HOST_CONFIG_OHCI (1U)

#define USB_HOST_CONFIG_IP3516HS (0U)

 

After running SW and inserting USB flash, there is no debug debug message output.

Just display "host init done".

Let me know if any suggestion.
