USB0 host mode configuration for AM335

Radhika Gandhi

Hi,

I want to set USB0 to HOST mode on my board which is a design based on AM335x.

In AM335x EVM, USB0 is set to OTG and USB1 is set to HOST.

The board file board-am335xevm.c contains the following code for USB configuration

static struct omap_musb_board_data musb_board_data = {
   .interface_type   = MUSB_INTERFACE_ULPI,
   /*
   * mode[0:3] = USB0PORT's mode
   * mode[4:7] = USB1PORT's mode
   * AM335X beta EVM has USB0 in OTG mode and USB1 in host mode.
   */
   .mode           = (MUSB_HOST << 4) | MUSB_OTG,
   .power       = 500,
   .instances   = 1,
};

To set USB0 to HOST I have changed above code to

.mode = (MUSB_HOST << 4) | MUSB_HOST.

The kernel compiles, but when I try to run, it crashes giving an error --- "Unable to handle kernel NULL pointer dereference at virtual address 00000018"

What could be the problem ? How can I set USB0 to HOST mode ?

Regards

Radhika,

Can you post the complete crash log and the System.map file of your kernel?

Hello Renjith,

Find the complete boot log and kernel config file attached.

Thanks and Regards

Attaching the kernel config file. Got missed in the earlier mail.

Radhika,

Are you using a RALink WLAN module? Have you seen the error occurring if the module is not connected?Are you inserting an ralink driver after booting up? If so, try not to insert the module and see the behavior.

Hello Renjith,

The RALink USB module is always plugged in. I am not plugging it during boot-up. This module is on USB1 interface of AM335x. I am seeing a crash during boot-up when USB0 is configured as HOST. If USB0 is configured as OTG, the system works fine. Nothing is connected on USB0.

Radhika,

In you .config file the USB controller glue interface used is CONFIG_USB_MUSB_TI81XX_GLUE=y CONFIG_USB_MUSB_TI81XX=y, I don't think AM335x is using the same interface as 81xx's. Could you please check this? Also please post the link to the kernel version that you are using.

Hello Renjith,

I checked the defconfig file of AM335x EVM from TI (arch/arm/configs/am335x_evm_defconfig), the Platform Glue Layer configuration is CONFIG_USB_MUSB_TI81XX=y.

I have not changed it in my config file.

Radhika,

If you see the crash log "Modules linked in: rt2800usb(O) rt2800lib(O) rt2x00usb(O) rt2x00lib(O) mac80211(O) cfg80211(O) compat(O)" says that these modules are inserted into the kernel.

Also if you see the .config file these modules are not included in kernel and not as modules also.

# CONFIG_CFG80211 is not set
# CONFIG_LIB80211 is not set

So, could you please check whether these modules are present in your filesystem and see whether its getting inserted also. From that you'll be able to figure out whether its really getting compiled for this particular kernel or whether you are using some old ones or not. If so, please compile it again and use it if required.

Hello Renjith,

The Wifi driver is compiled in the filesystem. It is inserted by the init.rc script. The WiFi works properly and I am able to browse. It is problem with USB0 port which when configured as HOST instead of OTG, the kernel crashes during boot. USB1 which contains the WiFi is working fine.

Regards

Radhika

Radhika,

I understand that USB0 is the problem. But to debug this further, we need to figure out what in USB0 is causing the trouble. As a first step, if we can try removing the modules and see whether any function call from the above modules are causing the trouble or not. Also, if the modules are not compiled with the latest kernel configuration as reference this can happen. Please try removing the modules one by one so that we can pin point which module is creating the trouble.

Hello Renjith,

I touched some files in WiFi source code, to see if it compiles. When I compile android, WiFi also gets compiled.

I will try removing the modules one by one and then get back.

Thanks and Regards
