My board is FSL board imx6ul EVK board.
I want to realize the function of USB virtual serial port.
I tried to config uboot using uboot 2016.03 and 2017.11,but failed .
So could anybody tell me how to config the uboot and what do I need to pay attention to?
Thank you !
Hi wang,
do you mean that you are not able to see the uboot output in the console?
Hi,Carlos_Musich
I didn't mean that.let me give an example to describe the problem .
If I config the linux kernel 4.1.15 like this :
make menuconfig
Device drivers --->
USB support --->
<*> ChipIdea Highspeed Dual Role Controller
ChipIdea device controller
<*> USB Gadget Support --->
<*> ChipIdea Highspeed Dual Role Controller
ChipIdea device controller
<*> USB Gadget Support --->
<*> USB Gadget Drivers (Serial Gadget (with CDC ACM and CDC OBEX support)
make and load zImage into board,plug the board into computer using usb cable .
In PC I installed gadgetserial driver ,
when I open the device manager , I find a serial port device :Blackin Com Port (COM4)
Now I want to do this in the uboot ,don't use linux kernel .
So how to config the uboot to implement this function .
