LPC55S69 USB host doesn't work

[kingchen-2024]

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.

SDK           ：  SDK_2_16_000_LPCXpresso55S69，

example  :     usb_host_hid_mouse

tool           :     KEIL

The Jumper settings:
J6 1-2 and J7 open for high speed mode

like:

The mouse is not work:

I checked my demo board. It can run 150MHz.

And make sure J6 2-3, J7 shut, Full speed, P5 power inserted. And I tested USB device CDC demo full speed P10, which is no problem running at 150MHz.

any suggestion?

If you are sure your EVK MCU is 0A version, please use it in 100MHz or lower.

0A version doesn't pass full test under 150MHz. Only 1B pass it.

I know in some condition 0A can also work under 150MHz, but we can't guarantee its performance.

[kingchen-2024]

But I changed BOARD_BootClockPLL150M() with BOARD_BootClockPLL100M().

It is the same result. And I took the OTG cable for test.

The chip mark date is 1850.

any suggestion?

Please make sure you have external power supply and try again.

[kingchen-2024]

Yes, I didn't revise anything.

I took SDK V2.7 version.

It seems that I found the issue. The default SDK example (usb_host_msd_fatfs_bm) is initial MCU 150MHZ. But my LPC55S69-EVK mcu is 0A version, which should be configured 100MHz max.

I will download the old SDK and try again.

Thanks
