USB port: HW design and USBMODE register question

Qmax

I'm not able to make USB1 port working on our custom board based on AM335x. The port must work in host mode only, but in the HW design the USB1_ID pin has been left floating and the USB1_VBUS is connected to 5V power (always on since the boot even if nothing is connected to USB port). Could it be a problem?

I'm booting with Linux, and I've modified the MUSB Controller instance 1 to be in host mode, therefore writing USB1MODE register to ignore USB1_ID pin. Everything seems fine during initialization, but when I plug a device, even if it is power, it seems not to be detected by the kernel.

Any suggestion? Thanks.

USB1_VBUS is an input pin to sense the Vbus. USB1_DRVVBUS should be used for driving 5V onto the bus.

Since USB1_ID is not connected to you should enable software controlled ID pin logic. This requires MODE.D7 =1 (MUX enabled) and MODE.D8 = 0 (ID grounded).

You can read DEVCTL register value to see what is current controller mode by looking at DEVCTL.D7 bit (=0 means host ; =1 means device ; D7 valid only when D0 =1)

What are exactly MODE and DEVCTL looking at AM335x Tec. Reference Manual?

I am setting USB1MODE (offset 0x00e8 of USB0_BASE 0x4740 1000) bit 8 to 0, to force host mode. But bit 7 is reserved in TRM document: do I need to set it???

DEVCTL seems at offset 0x460 of USB0_BASE, so it is in USB0 Core registers which are not described in TRM? What these registers are used for?

Initialization seems fine, but...

...but if a read registers (I've modified the debugfs to dump both), both DevCtl are 0x99, therefore "USB devices" as per your explanation. In fact the controller does not drive high the USB1_DRVVBUS, which is the behaviour I would expect if it was in peripheral mode:

DEVCTL is mentor core register which are not added in TRM. You can refer http://www.ti.com/lit/ug/spruer7e/spruer7e.pdf for Mentor only registers (starting offset 0x400) as they are same across all musb controllers. This document as enough details of DEVCTL and other mentor registers.

USB1MODE is at offset 0xe8 as you correctly identified and MODE.d7 should be 1 and MODE.D8 = 0 for host mode. As there are two controllers so all the mentor core registers are seperately available for each of them. USB1 DEVCTL will be at 0x47401c60 whereas for USB0 it will be at 0x47401460.

You said USB1_DRVVBUS is left floating and USB1_VBUS is always on, you may want to check a similar issue reported at e2e.ti.com/support/dsp/sitara_arm174_microprocessors/f/791/p/169145/617763.aspx#617763 which got solved when DRVVBUS was used to activate VBUS.

Ajay,

Thanks for the doc about DEVCTL. I've downloaded a snapshot of v3.2-staging branch from git repository, and now I'm running tests with that version.

In ti81xx_musb_set_mode, MODE.d7 = 1 (USBMODE_USBID_MUXSEL bit) is done only if cpu_is_ti816x() return true: but on AM335x EVM this function returns false, so this bit is never set. Is this correct? Or do I need to modify the code to set it?

Thanks for the hint. We have removed the connection between USB1_VBUS pad and +5V, connecting it to the VBUS of USB1 port that is expected to be driven by the Controller with the USB1_DRVVBUS pin. Looking at TRM it seems this is done automatically by the Controller. I do not find anything in musb source code to drive this pin. Unfortunately we have another HW constraint that we cannot workaround easily: USB1_VBUS and USB0_VBUS are connected together . I've run some more tests: these are some logs that I captured on TI AM335x EVM board at init:

.....

Both are taken with no device connected on USB ports, nor on USB0 neither on USB1. When musb_start is called for port (1) , the DEVCTL has the BDEVICE bit high on both boards, even if port has been configured in host mode; the main difference is the VBUS bits that are 0x2 on EVM and 0x0 on our board. Then a different interrupt occurs: on EVM a 0x100 interrupt, which moves state to a_wait_vrise and DEVCTL to 0x19. While on our board a 0x01 interrupt occurs, with DEVCTL changed to 0x91, on port (1) but also on port (0)!

When I plug a device on USB1 host port on our board, DEVCTL on port (0) move to 0x80 and no iterrupt arises:

[   74.200912] XXXX (0) OTG timer devctl 0x91 (b_idle) (otg_timer)

[   76.206632] XXXX (0) OTG timer set DEVCTL to 0x81 (otg_timer)

And when I un-plug it:

[   32.200917] XXXX (0) OTG timer devctl 0x80 (b_idle) (otg_timer)
[   32.206618] XXXX (0) OTG timer set DEVCTL to 0x81 (otg_timer)

[   34.206595] XXXX (0) OTG timer set DEVCTL to 0x91 (otg_timer)

On the other hand, USB0 (perpheral port) is working fine if nothing is connected on USB1.

Max,

In TI PSP driver we have disabled the SW controlled IP pin logic for AM335x but as you need to use it for your custom board so you should change the same. USB1_DRVBUS will be driver when SESSION is set and controller detects the ID pin to be grounded (either through connector if MODE.D7 =0 OR through MODE.D8 = 0 when MODE.D7=1)

I think you should definitely not connect USB0_VBUS and USB1_VBUS as mentor controller senses VBUS using these input pins and decides on USBx_DRVVBUS.

Port1 DEVCTL becoming 0x91 seems to be due to VBUS always ON in yur board and thus controller think it to be in device mode connected to external host. This was exact same issue in other e2e thread.

Hi, Ajay,

I have some problem with usb. Could you help me? It is the USB1 port working on our custom board based on AM335x. When I run a Qt applition, the USB will not work immediately and get this information:

reg 0x4c, usb read 1 fail, status:-110 value=0x0, vendorreq_times:3

I doubt that the usb mode has been changed,so I've done the work below.

Before run a Qt application.

root@am335x-evm:~# cat /proc/driver/musb_hdrc.1

Status: MHDRC, Mode=Host (Power=f0, DevCtl=5d)

OTG state: a_host; active

Options: pio, otg (peripheral+host), [eps=16]

Peripheral address: 00 Root port status: 00000503

After run a Qt application.

root@am335x-evm:~# cat /proc/driver/musb_hdrc.1

Status: MHDRC, Mode=Host (Power=f0, DevCtl=99)

OTG state: a_host; active

Options: pio, otg (peripheral+host), [eps=16]

Peripheral address: 00 Root port status: 00000503

Why this happen? What shoud I do to let the USB1 keep with HOST mode ?

What USB device is connected to USB1 host port? What does the Qt app do to the USB device?

Does the issue happen every time run the Qt app?

Before start the Qt app, please do 'dmesg -c', then start the Qt app, then does 'dmesg' command give any new kernel message?

Do you use USBx_MODE register or grounding ID pin to put USB1 in host mode?

By the way, I think it is better to start a new thread post whenever you have a new query. You can add URL reference in your post if you think other posts are relevant. Thanks.

Hi, Bin Liu

Thank you for reply.

On our board, there is a usb hub connected to USB1 host port, and I've programmed the USB1_MODE Register IDDIG bit field with a value of '0' value. As for usb hub, there are 3G, wifi and usb to SATA module connected to it.

The Qt app have nothing to do with USB1, it just a video surveillance app.If I don't run the application, everyting is normal. Once I run it, as I mentioned before, the USB1 mode switched from host to device and make the modules which connected to hub not work.

Here is the demsg info.

From the log I am unable to explain what happened. It shows USB EP0 traffic timeout. Have you measured ARM load? Is that because the Qt app causes ARM is fully loaded and no time slot to serve USB requests?

Just want to double check, the exact value of USB1_MODE should be 0x80 for host mode.

Do you use TI released Linux SDK package on AM335x EVM? I see a couple problems from the log.

- EHCI/OHCI drivers are loaded which shouldn't. AM335x does not have those controllers;

- Kernel crashes in pvrsrvkm driver right after kernel booted. You probably want to fix this issue first.

Hi, Bin Liu

Thank you for you reply.

I'm sure that USB1_MODE's value is 0x80. We use the TI SDK package on AM335x EVM. The usage rate of CPU and memory is very low, so I don't think it's the problem of ARM fully loaded. I have unloaded EHCI/OHCI drivers, but the problem still happened.

So I have some questions below:

1.Where is the persrvkm driver's source codes? I can't find them.

2. As I mentioned before, USB1 mode switched from host to peripheral (DevCtl register's value switched from 0x5d to 0x99) after run the Qt app. What kinds of reasons(software or hardware) can cause the mode change?

I hope you will help me.Thank you.

Sorry, I cannot think of any reason why the Qt app will affect the USB module at this moment. Maybe you can try to turn on MUSB ISR debug messages to see if that gives any hint. Please do the following then run your test.

echo "file ti81xx.c func ti81xx_interrupt +p" > /sys/kernel/debug/dynamic_debug/control

The pvrsrvkm driver source code is in the installer 'Graphics_SDK_setuplinux_4_08_00_02_minimal_demos.bin' inside the SDK package.

http://software-dl.ti.com/dsps/dsps_public_sw/am_bu/sdk/AM335xSDK/latest/index_FDS.html

By the way, you don't need to install the pvrsrvkm modules if you don't use OpenGLES.
