LPC55S69 USB host doesn't work

kingchen-2024 — Wed, 08 Jul 2020 09:43:17 GMT

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.

The default SDK example(usb_host_msd_fatfs_bm) without any modification is for full speed mode.

just make sure J6 2-3 and J7 shunt for full speed mode.

Did you ever try the default project without modification?

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

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.

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.

Hi,
I have a similar issue for the default SDK example (usb_host_msd_fatfs_bm). I am using SDK 2.8.2. my LPC55S69-EVK MCU is marked as "sSD19401B". I did not modify anything in the code, I also connect external power on P5, use P10 (USB0 FS) as host. J6 is 2-3, J7 shunt.
I also tried the device mouse demo, it works.

After that, I also tested the demo on HS port (I modified usb_host_config.h and enable the IP3516HS controller, changed the jumper on J6 and J7). it doesn't work either. Device demo works on that HS port.

I also changed the clock to use 100MHz only. still same issue.
I measured VBUS pin, there is no power on VBUS

I could reproduce the issue using 0A silicon but it's not reproducible using production silicon (1B).

As stated here, it is recommended to replace Revision 0A silicon with 1B silicon on boards with older board revision than Revision A2.

I tested PLL0 100M on my side. this code can't run successful on my side.

by checking the the USB host clock init code, I change

CLOCK_EnableUsbfs0HostClock(kCLOCK_UsbfsSrcPll1, 48000000U);

CLOCK_EnableUsbfs0HostClock(kCLOCK_UsbfsSrcPll0, 48000000U);

fix the issue

the output on uart terminal is all successful.

Have a nice day,

Hi,

I just tried your suggestion:
1. changed the clock to 100M

BOARD_InitPins();
BOARD_BootClockPLL100M();
BOARD_InitDebugConsole();

2. changed the USB FS clock to use kCLOCK_UsbfsSrcPll0

#if ((defined USB_HOST_CONFIG_OHCI) && (USB_HOST_CONFIG_OHCI > 0U))
CLOCK_EnableUsbfs0HostClock(kCLOCK_UsbfsSrcPll0, 48000000U);
#if ((defined FSL_FEATURE_USBFSH_USB_RAM) && (FSL_FEATURE_USBFSH_USB_RAM > 0U))
for (int i = 0; i < (FSL_FEATURE_USBFSH_USB_RAM >> 2); i++)
{
((uint32_t *)FSL_FEATURE_USBFSH_USB_RAM_BASE_ADDRESS)[i] = 0U;
}
#endif
#endif /* USB_HOST_CONFIG_OHCI */

I still have the same issue. I believe I am using '1B' version of the MCU. SYSCON->DIEID->REV_ID is 0x1

Could you share with me the log output on your side?

Also could you also check the HS port?

my part is 1B as well.

Attached is my video.

FYI.

This video is for a ScribeMotorController project. Could you double check it?

Re: LPC55S69 USB host doesn't work

ZhangJennie — Tue, 22 Sep 2020 06:48:56 GMT

Please check again.

@yingbohu71 , could you please provide a picture of your board and your setup?

Please make sure it's labeled as "Revision A2"

Re: LPC55S69 USB host doesn't work

yingbohu71 — Thu, 24 Sep 2020 20:28:48 GMT

Here are the pictures how I setup the board hardware and also the screen shot of the IDE and output

Re: LPC55S69 USB host doesn't work

yingbohu71 — Thu, 24 Sep 2020 20:29:25 GMT

The video is correct. Thanks

Basically, default configuration should work on this demo for FS USB. A few things to consider:

Make sure you are using the latest SDK and MCUXpresso IDE from MCUXpresso website
Erase your project and start from scratch
Make sure your power supply is working well, please try other USB cables or other power source
Review all cables and USB dongle
Try another LPCXpresso55S69

If none of this work, please contact a local representative and try requesting another evaluation board.

Here is the latest update.

1. We (I and co-worker) tested on 3 Rev A2 boards and 1 Rev A1 board with and without the 2 settings. We just bought 2 new RevA2 boards to test this.
2. Device mouse demo works fine on all 4 boards.
3. We use J-Link interface installed with LPCScrypt 2.1.1.15.
4. We notice in your video, the project has a "0" in the name, and ours doesn't.
nxp video: lpcxpresso55s69_0_host_msd_fatfs_bm
ours: lpcxpresso55s69_host_msd_fatfs_bm
5. We use latest IDE and SDK just downloaded from the website. Please (NXP) download and install both to test the same thing.
6. Try 3 boards.
7. If it works, export the working project and send to us. Send a photo of the board so we can check jumper settings.
