USB mouse for DM6446

Swapnil,

I hope you are using mini-A plug to connected USB mouse/keyboard to DM6446 OR have setup the ID pin jumper appropriately to make DM6446 work in host mode.

Please provide the output of cat /proc/driver/musb_hdrc

Regards,A
Ajay

Hey,

      Thanks for replying.

We are using mini-A plug and also we have set up jumper appropriately to make DM6446 work in host mode.

On cat /proc/driver/musb_hdrc , we didn't find such "musb_hdrc" file or directory.

Regards,

Swapnil Ashtekar

You should enable debug at USb support > Inventra-> Enable debug messages

Reagrds,
Ajay

Yeah, It's done.

We have also set Driver mode(USB Host) to USB Host. 

Thanks.

Regards,

Swapnil

Are you using any TI released Linux source ? I think you are using community's source and thus procfs will not be available. I would recommend to use TI releases sources available at http://arago-project.org/git/people/?p=sneha/linux-davinci-staging.git;a=summary

Regards,
Ajay

We are using dvsdk_1_30_01_41 downloaded from the link :

http://software-dl.ti.com/dsps/dsps_registered_sw/sdo_sb/targetcontent/dvsdk/mv_dvsdk/v1_30/index.html

Thanks.

Regards,

Swapnil Ashtekar

Then it must have "Enable debug messages" and drivers/usb/musb/musb_procfs.c file. If you have enabled "Enable debug messages" then tou should see /proc/driver/musb_hdrc entry. Can you check these things again?

Regards,
Ajay

Hi,

There is no musb_hdrc on board.

Welcome to MontaVista(R) Linux(R) Professional Edition 4.0.1 (0600980).

Thanks

As you are using v2.6.10 based kernel so I think you may have debug level to be set in "Eable dbeug message". if so then set it to '1' and not '0'. Also check if musb_procfs.c is getting compiled and procfs related call are successfully going through.

Regards,
Ajay

Hi,

There isn't any Enable Debug Message option in menuconfig.

Please check the Inventra option in menucofig. Is it similar to the one you said.

Device Drivers---> USB Support-->>Inventra USB Highspeed Dual Role Controller Support.

Thanks

I changed the logging level to 1 and now i can see musb_hdrc.

Swapnil,

DEVCTL register value shows that Vbus is on and port is in host mode but the power register (=0x71) shows D0 bit to be set which is SUSPENDM. Can you disable SUSPENDM in musb_start function of drivers/usb/musb/plat_uds.c file? Please let me know the status after this.

Regards,
Ajay

Hi,

   We searched SUSPENDM in musb_start function in driver/usb/musb/plat_uds.c,but could not find.

Please find attach plat_uds.c file.

Thanks

1157.plat_uds.txt

you need to comment out MGC_M_POWER_ENSUSPEND in musb_start.

Ajay

Hi ,

   I did what you suggested and compiled the kernel.  After booting and connecting USB mouse, I am getting same errors.

Is problem with USB mouse related to i2c bus ? I am wondering is it like USB mouse is getting power, but not working due to i2c bus errors(Please see booting sequence above).

After connecting the USB mouse i get following error:

root@10.42.43.10:~# DaVinci I2C WARNING: i2c: NACK detected

Hey  Ajay,

               I installed new dvsdk version 2.0 with kernel 2.6.18,

now when I do cat /proc/driver/usb/musb_hdrc , after connecting usb mouse, I get following

Status: MHDRC, Mode=Host (Power=f0, DevCtl=90)
OTG state: a_wait_vfall; active
Options: cppi-dma, host, debug=1 [eps=5]
Root port status: 00000100
DaVinci: ctrl=00 stat=0 phy=1f0
       rndis=00000 auto=0000 intsrc=00000000 intmsk=01f71e1f
CPPI: txcr=1 txsrc=0 txena=f; rxcr=1 rxsrc=0 rxena=f

Still usb mouse getting power but isn't working.

Please suggest possible solutions.

Thanks.

DevCTL=0x90 shows that controller is in device mdoe. please make sure to eihter use mini-A plug (different than mini-B)  or jumper on evm to make sure id pin is grounded.

Ajay

Hey Ajay,

                On the same kernel, on connecting the mass storage device and doing cat /proc/driver/musb_hdrc,

we find

     root@10.42.43.10:/# cat /proc/driver/musb_hdrc
Status: MHDRC, Mode=Host (Power=f0, DevCtl=5d)
OTG state: a_host; active
Options: cppi-dma, host, debug=1 [eps=5]
Root port status: 00000503
DaVinci: ctrl=00 stat=1 phy=1f0
        rndis=00001 auto=0000 intsrc=00000000 intmsk=01f71c1f
CPPI: txcr=1 txsrc=0 txena=f; rxcr=1 rxsrc=0 rxena=f



And now on connecting USB Mouse, we get

root@10.42.43.10:/# cat /proc/driver/musb_hdrc
Status: MHDRC, Mode=Peripheral (Power=f0, DevCtl=99)
OTG state: b_idle; inactive
Options: cppi-dma, host, debug=1 [eps=5]
Root port status: 00000100
DaVinci: ctrl=00 stat=0 phy=1f0
        rndis=00001 auto=0000 intsrc=00000000 intmsk=01f71e1f
CPPI: txcr=1 txsrc=0 txena=f; rxcr=1 rxsrc=0 rxena=f


I didn't  understand the change in the DevCTL values, and while doing this all, the pin number 2 and 3 of J7 are short.
To use USB Mouse, which mode is preferable ?

Thanks.

This is strange. D7 bit of Devctl should be '0' in both cases of mass storage or mouse. In all host scenarios ID pin should be shorted and DECCTL.D7=0.

Regards,

Ajay
