About a USB driver of LinuxBSP for i.MX6 Solo

Dear all,

 

We use i.MX6Solo.
And L3.0.35_4.0.0_130424_source.tar.gz is used.

 

We have some questions about Linux BSP.

 

In our system, we think about the following configuration.
We use this for the maintenance of our system. (like RS232C)

 

     [PC(USB Host)]<====[USB to serial]====>[i.MX6 original board(USB Device)]

 

In this case, we understand that we should use "g_serial" included in the USB gadget of Linux BSP.

 

[Question1]
We want to modify this "g_serial".
However, the "g_serial" is a module form.

Can "g_serial" be modified?

 

[Question2]
Is there the document about "g_serial"?

 

[Question3]
When we use USB like RS232C, is there the good idea?

 

[Question4]
We understand that the USB driver included in Linux BSP decides the operation of the USB port by a state of USB_OTG_ID.

      - Low => USB_OTG of i.MX6 works as Host.
      - High => USB_OTG of i.MX6 works as Device.

Is my understanding right?

 

May I have advice?

 

Best Regards,
Yuuki
