Linux/AM3352: gpio0 wake-up disturbed by usb1 connection

user5102395

Part Number: AM3352
Other Parts Discussed in Thread: TUSB9260, PCM2906C

Tool/software: Linux

Dear Specialists:

Strange issue. Signals from gpio0 bank cannot wake-up the system when usb1 connected to a module using Host mode.

I'm using Linux(kernel 4.14.71) based on ROCESSOR-SDK-AM335X( kernel 4.14.y branch) to run on a custom board , Processor is AM3352, and the usb1 is designed to connect to an Am Telecom (amm570)LTE module, everything goes well except the gpio0 to wake-up system from standby mode.

1, when comment out the usb1 section in arch/arm/boot/dts/my_board,dts, that is meaning not use usb1 connection. gpio0 (number 23)from a button can wakeup the system( using command as follow) immediately

rtcwake -d rtc0 -m standby -s 10

2, but when add the usb1 section to the board's devicestree file, the gpio0(number 23 , also number 22) signals can not wake up the system)

&usb1_phy {

status = "okay";
};

&usb1 {

status = "okay";
dr_mode = "host";
};

3, When using another version Linux kernel . ROCESSOR-SDK-AM335X( kernel 3.14.y ) , everything is OK no matter using usb1 or not.

I think there is no problem in hardware design, according to the checklist ( http://processors.wiki.ti.com/index.php/AM335x_Schematic_Checklist#USB

and the success use case in version ROCESSOR-SDK-AM335X( kernel 3.14.y )

Hi,

I am trying to understand the usb topology on your board. You mentioned AM335x USB1 is connected to a LTE module, but

USB1 is enumerated as USB bus2, which is connected to a 4-port USB hub. Can you please explain?

By the way, is the LTE module permanently mounted on the board or connected to a USB connector?

Can you reproduce the same problem on any AM335x EVM, such as the GP EVM, Starter Kit, or Beaglebone Black?

Dear Bin Liu

Yes, just as you mentioned, the LTE module is permanently mounted on an expand board which connect to main board through an XIO connection.

Exactly as the log showed, USB1 is connect to a 4 ports hub, and one of the port is connect to the LTE module.

I have no any AM335x EVM, test board or Starter Kit,

Hi,

You are disabling AM335x USB module through devicetree, so I am trying to understand is the am335x usb module or the LTE modem which affects the GPIO wakeup. Please answer my following questions.

What is the 'XIO' connection? I am not familiar with the term.
Where is the hub located? on the main board or the expansion board with the LTE module?
Your kernel log shows two devices connected to the hub, TUSB9260 and PCM2906C. Which one is the LTE modem? Or the modem is not connected in that test?

If you use command 'echo standby > /sys/power/state' instead of 'rtcwake -d rtc1 -m standby -s 10' to put the system into standby mode, can you use the GPIO button to wake up the system?

By the way, it shouldn't be related to this issue, but the resister R189 is too high, please replace it with a 0-ohm resister.

Hi,　Bin Liu:

Sorry to not explain clearly about the XIO connection and the expansion board. the XIO is as follows

which connect with an expansion board.

On the test environment, AD[15:0] on the expansion board is used for I/O and not connect to anything.

SPI1 is used for the bus of the expansion board. and the USB1 is connected to a hub which located in the expansion board.

TUSB9260 is a bridge which change data form USB to Serial ATA, but not connected with any Serial ATA devices.

PCM2906C is refer to audio device.

After confirmed the hardware expansion board, Actually, the LTE modem does not connect to the USB1 hub in the test environment.

I also use command 'echo standby > /sys/power/state' , the GPIO button can wake up the system if not use USB1 connection.

thanks for the attention about the R189, I will tell the hardware team to consider it.

Hi,

Thanks for the clarification.

user5102395 said:
I also use command 'echo standby > /sys/power/state' , the GPIO button can wake up the system if not use USB1 connection.

but gpio button doesn' wake up if use USB1 in this test, correct?

If you enable USB1 in devicetree as mentioned in your first post, but don't connect the expansion board to the main board, (basically the hub and its down stream devices are not attached to USB1), can you use the gpio button to wake up?

Dear Bin Liu:

gpio(bank0) button can not wake up the system in the conditions as follows:

1, use USB1 in the devicetrees

2, the expansion board connected to the main board

3, Linux(kernel 4.14.71) based on ROCESSOR-SDK-AM335X( kernel 4.14.y branch)

1 and 2 and 3

gpio(bank0) button can wake up the system in every one of the following conditions is satisfied

1, not use USB1 in the devicetrees

2, the expansion board not connected to the main board

3, Linux kernel(3.14.79) based on ROCESSOR-SDK-AM335X( kernel 3.14.y )

1 or 2 or 3

Hi,

Please just confirm - does the issue happen in the following condition?
- usb1 is enabled in devicetree;
- the expansion board is NOT connected to the main board;
- using kernel v4.14.71.

If I can use Beaglebone Black to test the use case with gpio0_26 or gpio0_27.

0 user5102395 over 5 years ago in reply to Bin Liu

Dear Bin Liu:

The issue did not happen in the condition you mentioned, because the expansion board is NOT connected to the main board.(that is means, usb1 pin is not connected with any devices in the test environment).

of course, you can use Beaglebone Black board to test it. According to its PCB, there are two USB1 connectors.

Hi,

Yes, the BBB has USB1 port in host mode, and gpio0_26 and gpio0_27 on the expansion header. I can use them to run the test case.
Do you think if I connect any usb device (for example, a thumb drive) to the BBB USB1 host port, and use gpio0_26/27 to wake up from system standby, this issue should happen?
If not, how should I make the BBB setup to close to your use case?

Hi, Bin Liu:
According to the fact that the issue happened in my test environment, if you connect some usb device to the BBB USB1 host port, using
gpio0_26/27 can not wake up the system from the standby mode.
if it can, tell me the kernel version you used.

0 Bin Liu over 5 years ago in reply to user5102395

TI__Guru*** 125366 points

Hi,

The AM335x GP EVM already has gpio0_2 and gpio0_3 connected to two buttons which can be used for gpio wakeup out of the box, without any hw or sw modification. I can use any of two buttons to wake up with usb devices enumerated on the USB1 host port, using the Processor SDK v5.1.0.11 and v5.0.0.15 pre-built images. Attached below is the full kernel log.

Hi, Bi Liu:

It seemed something wrong with my board, or system software.......

by the way,, can you tell me the result value of the follow command:

cat /sys/bus/platform/devices/<usb1-phy-id>/power/wakeup

thanks.

Hi,

I noticed you have marked this issue is solved, I am curious did you find the root cause on your system? what was the problem?

Hi, Bin Liu:

I have not found the real reason about this problem, and confused by the fact that the BBB board is OK and in my board, it is not.

Anyway, I found if I do this command:

echo enabled > /sys/bus/platform/devices/47401b00.usb-phy/power/wakeup

the gpio(bank0) can wake up my system no matter which kernel version used or with/without expansion board connected.

the other method is just to modify the kernel(SDK v5.1.0.11) by:

①comment out the Line 1178 : irqc->flags = IRQCHIP_MASK_ON_SUSPEND; in file drivers/gpio/gpio-omap.c

②comment out the Line 81 : device_set_wakeup_enable(dev, false); in the file drivers/usb/phy/phy-am335x.c

and it worked.
