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

Hi Yuuki
1.2. for usb "g_serial" one can look at
Linux-USB Gadget API Framework
and attached Linux Manual Chapter 41 CHIPIDEA USB Driver,
in most cases there is no need for modification of this driver
3. this is common approach, seems this is not bad idea
4. yes it is right
Best regards
