DRA829J: Enable USB host in u-boot (and kernel)

Hi Bo 

Do you want you usb host to work in usb3.0 in UBOOT or its ok if it works in USB2.0 ?

can you share the dtb as well i want see what is the mode used for both of the USB subsystem.

Regards
Diwakar

USB2.0 would be fine in u-boot as well as in Linux.

I couldn't upload the file here. Here is a link: https://easyupload.io/rviijo

Thanks!

/Bo

HI Bo 

I would suggest you to remove the seredes configuration and configure the dtsi according to the USB 2.0 also you need to change the dr_mode from OTG to host.

You can just do drag and drop here.

I'm sorry, I should have mentioned that we have an USBC port on usb0, so I can't remove the serdes blocks.

usb0 is USBC for dfu

usb0 is connected to a hub serving two usb-host type A ports according to the above.

Best regards,

/Bo

Serdes configuration is need if you want to support USB3.0 if you are ok with the USB  2.0

you can remove the serdes configuration and can use usb2phy.

That is new information for me. Thank you.

Do you have an example of such a configuration?

Regards,

/Bo

Hi Bo 

By default in DRA821(j7200) we not configuring the USB subsystem for USB3.0 you can take a reference from the j7200 dtsi 

ref:k3-j7200-common-proc-board.dts

do let me know if you still face any issue.

Regards
Diwakar

Diwakar,

It turns out our host ports are indeed USB3 capable, so I guess serdes is needed. Here is a fragment of our schematic:

The serdes3 connection is working fine. We can dfu properly through that usb port. The trouble I am having is with the top USB1 connection. It connects to the hub just as on BeagleBoneAI64.

Can you confirm that our serdes2 settings look ok?

Regards,

/Bo

Hi Bo 

As i said earlier if you are ok with USB2.0 on type c port you can remove the seredes configuration and can use usb2.0.

Bo Mellberg said:

even if you are not doing a serdes configuration still dfu can work as it uses high speed mode.

so you mean for you USB 1 is not coming up in the UBOOT what is the dr_mode set there also please share the dtb by just doing a drag and drop  i will take a look at it.

Diwakar

Diwakar Dhyani said:

See first post. mode is set to "host".

I'm sorry, either insert file or drag and drop works for me. Please use this link for the u-boot.dtb: https://easyupload.io/rviijo

Best regards,

/Bo

HI Bo

I am not able to download the dtb from the link as the site is blocked for us.

Regards
Diwakar

1830.u-boot.zip

I was able to upload if I changed the file type to .zip. Please just change it back to .dtb after download.

Best regards,

/Bo

Hi Bo 

not able to extract 

can you try these changes 

&usbss1 {
    pinctrl-names = "default";
    pinctrl-0 = <&main_usbss1_pins_default>, <&mcu_usbss1_pins_default>;
    ti,vbus-divider;
    ti,usb2-only
};

&usb1 {
    dr_mode = "host";
    maximum-speed = "high-speed";
};

Regards
Diwakar

I have already tried those settings. They didn't help.

Regarding the file, it is NOT a zip-file. Just rename the file from u-boot.zip to u-boot.dtb.

Another hint might be this message when booting to Linux:

[ 2.253543] cdns-sierra-phy 5020000.serdes: failed to get reset phy@0
[ 2.260125] cdns-sierra-phy: probe of 5020000.serdes failed with error -16

What is the error you were getting with these changes ?

why the mode is peripheral ?

Regards
Diwakar

You are looking at the USBC port on usb0, which is working fine.

Below, on address 0x6400000 you see usb1, which has dr_mode="host"

Regards,

/Bo

if you see the logs its already working 

see the address usb@6400000  the controller is up and running 

i dont know what exactly you want to achieve here , my understanding  was you want both the usb subsystem USB0,USB1 to be  accessible in uboot.

Regards
Diwakar

Right now I just want to confirm that the HW is ok, and that we can use the USB host ports, but no devices can be detected either in U-boot or in Linux.

For example, on the BeagleBoneAI64, i can see this:

debian@BeagleBone-AI64:~$ lsusb
Bus 002 Device 002: ID 0451:8140 Texas Instruments, Inc. TUSB8041 4-Port Hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 0451:8142 Texas Instruments, Inc. TUSB8041 4-Port Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

On my board, nothing is being reported:

root@asp3:~# lsusb
root@asp3:~#

As I wrote above, the probing seems to fail:

Hi Bo 

in uboot controller is up so you should see a usb device is there is no issue 

in linux its failing because of some missing serdes configuration can you send me the full boot logs.

Regards
Diwakar

Diwakar,

I'm not convinced that it is working in U-boot. Look at this log:

Hit any key to stop autoboot: 0

You see that it is unable to probe serdes2 (5020000). The same is happening in Linux.

This is the dmesg of Linux boot:

Any ideas? Still struggling here.

/Bo

Hi Bo 

Currently occupied with the other high priority task give me a week i wiil try to respond on this.

Regards
Diwakar

Hi Diwakar,

Ouch, that hurts. The HW teams sets the layout for the next engineering prototype this Wednesday and I have yet to give them an OK on the USB host solution.

Are there any other USB/Serdes experts that can assist?

Best regards,

/Bo

Hi Bo 

Understood  your concern i will try to analyze the logs and will respond to you as earliest .

Regards
Diwakar

Hi Bo 

i am not seeing any serdes related logs in the logs which you shared above can you cross verify that.

Regards
Diwakar

Diwakar Dhyani said:

Correct. When booting into Linux, I don't see anything serdes-related. Should I see anything?

Comparing with the BeagleBone, there are no serdes stuff in dmesg either, but there I can see the hub and devices connected with "lsusb".

Regards,

/Bo

HI Bo 

can you do lsmod and see if any driver is getting loaded or not .

can you send me the BegleBone logs as well .

Regards
Diwakar

Diwakar,

There are drivers being loaded at boot. I build them not as modules but into the kernel:

Update: when I measure the USB1_DRVVBUS it is always 0. What might cause this?

Regards,

/Bo

Another update:

I can now get the host ports to work i u-boot by forcing them to USB2.0:

Hi Bo 

what was the mode you kept  ?

it is trying to do the role switch cdns3_hw_role_switch() did you kept OTG mode ?

Bo Mellberg said:

need to see if pad configuration is ok also is it high in uboot and linux it is low am i right?

Hi Diwakar,

On the working USB2 USB1_DRVVBUS is working ok, and shows 3.3V.

The current dts-tree looks like this now, usb0 is our USBC-port, used for dfu. usb1 is connected to the hub, just as on BeagleBone.

Why is trying to switch role? Isn't that set by the usb_serdes_mux?

Best regards,

/Bo

Hi Bo 

This doest seems to correct to me you are using usb2 only and then speed mentioned is super speed which is not correct it should be high speed 

why we are using serdes link as mentioned earlier if you are using usb3.0 in that case only we need serdes.

please refer <Linux sdk>/Documentation/devicetree/bindings/usb/ti,j721e-usb.yaml
                    <Linux sdk>/Documentation/devicetree/bindings/usb/cdns,usb3.yaml

for details about the properties.

The goal is to have usb3.0 on both usb0 and usb1. But the serdes configuration seems to be wrong.

Can you halp me get it working?

Best regards,

/Bo

Hi Bo 

can you add a print in the usb driver in linux so that at least will come to know why its is failing right now its bit difficult as we are not  getting any print in the linux.

share final dtb which you are corrently using  config file also can you dump these register

Diwakar,

There has been some progress. I think we can be content with usb2.0 in U-Boot, so I went on to Linux.

I removed the "ti,usb2-only" from the Linux dts, and now I see that it tries to probe through serdes:

HI Bo 

Can you share the above asked register dumps to make sure your serdes configuration is correct.

Hi Diwakar,

I tried to devmem2 those registers but only managed to read the two first ones:

Hi Diwakar,

I read the datasheet and the presumed addresses for the serdes ctrl lines are

Serdes 0: 00104080 and 00104084
Serdes 1: 00104090 and 00104094
Serdes 2: 001040a0 and 001040a4
Serdes 3: 001040b0 and 001040b4
Serdes 4: 001040c0, 001040c4, 001040c8 and 001040cc

HI Bo

 BeagleBoneAI64 uses TDA4VM soc 

i checked the data sheet 

0010 40A0h --> CTRLMMR_SERDES2_LN0_CTRL

0010 40A4h --> CTRLMMR_SERDES2_LN1_CTRL

0010 40B0h--> CTRLMMR_SERDES3_LN0_CTRL

0010 40B4h --> CTRLMMR_SERDES3_LN1_CTRL

can you dump the value of these register dont use 'l' option by default devmem2 will print 32 bit data.

also if everything goes ok with this we need to see serdes specific configuration 

we need to get the value for (SERDES 2/3 base address + reg offset)

Diwakar

Bo Mellberg said:

Hello Bo,

Is serdes2 being configured at U-Boot? Also, can you please share the complete device-tree nodes for:
serdes_wiz2, serdes2, usbss1 and usb1
with contents of the nodes from main.dtsi as well and not just the changes made in the board file.
That will be helpful to debug the issue.

Regards,
Siddharth.

Hi Siddharth,

Yes, Serdes is configured in U-Boot. At least I think so as I have it present in my top dts. Could it be that it needs to be configured in the u-boot-portion of the U-Boot dts?

In U-Boot, I have the following dts-files:

k3-j721e-asp3.dts
k3-j721e-asp3-u-boot.dts
k3-j721e-r5-asp3.dts
k3-j721e-r5-asp3-u-boot.dts

Which of these control the serdes setup? Currently I have only made changes in the top k3-j721e-asp3.dts

The complete node for Serdes and usb (in U-Boot, but looks the same in Linux), with all my changes comes here:

In main.dtsi:

Diwakar,

The register values comes here:

0010 40A0h --> CTRLMMR_SERDES2_LN0_CTRL - 0x0

0010 40A4h --> CTRLMMR_SERDES2_LN1_CTRL - 0x2

0010 40B0h --> CTRLMMR_SERDES3_LN0_CTRL - 0x2

0010 40B4h --> CTRLMMR_SERDES3_LN1_CTRL - 0x2

The below values are for serdes 2, @0502 0400 + offsets:

Yes, Serdes is configured in U-Boot.

If Serdes2 is configured in U-Boot, I assume it is being configured for USB3 protocol at U-Boot. If that's not the case, then it will be an issue.
You could try preventing Serdes2 configuration at U-Boot and let Linux configure it instead and check if that works.

Siddharth.

I turned all serdes2 stuff off in U-Boot. I can still not probe anything when it boots to Linux.

Hi Bo 

can you help us understand how you turned off the serdes in uboot , can you share those steps to make sure its the correct way.

Regards
Diwakar

Sure,

I commented out all serdes2 stuff in the k3-j721e-asp3.dts:

Bo,

Can you comment out the following lines within the file board/ti/j721e/evm.c in U-Boot source?

if (board_is_j721e_som())
	configure_serdes_sierra();

if (board_is_j721e_som())

configure_serdes_sierra();

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

if (board_is_j721e_som())
	configure_serdes_sierra();

They are present in the function board_late_init().

I'm afraid that didn't help either.

But going back, isn't it strange that the reset register differs from BeagleBone?

Register 0x0502040c read 0x92000000 on my board, but 0xb1000000 on BeagleBone. Those differing bits are the refclock selection and the dig_refclock selection.

Best regards,

/Bo

Bo,

Can you boot to Linux prompt and share the output of the following command?
k3conf dump clock

Regards,
Siddharth.
