USB on OMAP35x

Frank An
Prodigy 30 points

Hi,

I am testing the USB port with my OAMP35x EVM board and it doesn't seem to be working.

Here is what I have:
BSP: 1.0.2
kernel: 2.6.22.18-omap3
Board revision: D

Experiment 1: connect a USB thumb drive using a mini-A (5-pin) male to A connector with an extension for A receptacle
No response from the kernel (this is a known good drive and cable)

Experiment 2: connect a 4-port self-powered hub with mini-A cable to the board
again, the hub is not detected. Further connecting a usb keyboard or mouse to the hub doesn't do anything either.

So I looked through 1.0.2 release notes section 3.6.2 Known Issues and Limitations. It mentions that older rev of EVM requires two mods:
1. Select the ISP1504 PHY;
2. Remove large surge suppressor in the D+ and D- lines

Does anyone know if these are applicable to rev.D board? Do I need to do anything to enable the usb host mode?

Thanks in advance,

Frank

    Please follow below steps to test EVM in host mode.

     

    • Boot the kernel with USB support and insert the controller module if they are not built into kernel image.
    • Connect USB device to EVM with Mini-A plug towards EVM
    • If you don't see any new device attach log then use below command to switch on the bus power,

     

      • $ echo F > /proc/driver/musb_hdrc

     

    • Now the device should be detected and should work properly.

    Regards,
    Ajay

    Also make sure to connect the devices using a self powered USB Hub.

    Thanks,

    Thanks for your suggestions.

    I am using the default 1.0.2 kernel configuration which has USB bulit into the kernel (as well as the host controller support). See below for a dump for USB related settings in my .config file.

    On echo F > /proc/driver/musb_hdrc

    I get

    musb_stage2_irq 864: SUSPEND (a_idle) devctl 91 power e0

    I am using a mini-A (5-pin) connector connecting into the board, and it is self-powered. The same hub plugged into my linux machine (ubuntu-8.10) gets recognized properly (just to say the hub is ok).

    Other ideas?

    Frank

    Pl. ensure that the Mini-A to A-receptacle adapter is connected to the EVM MiniA/B port when the EVM boots up(either with or without the associated USB device).  I think this might be the cause of the issue you are facing.

    I will give that a try. Thanks.

    In the meantime, for those who have this working (usb kb and mouse), can you post your .config file and "dmesg | grep usb" dump so that I can compare what I am missing? Or if the my config and the boot message dump doesn't raise any suspicion, maybe it is a cable issue?

    Thanks a lot,

    Frank
