Can the console display using LCD framebuffer and use the usb keyboard to type command on the uboot framebuffer console?

 

Have anyone done this ?

 

Can it be realized?

people have done it on other boards, but i'm not aware of anyone doing it on a Blackfin exactly.  feel free to refer to the boards doing it, but we dont have any Blackfin-specific examples.

Thank you ,Frysinger.

 

If I want to use the usb in UBoot,whether the interrupt is needed?

 

As I know ,the interrupt is inhibited in uboot.

interrupts arent inhibited, they just dont get used by code in u-boot already.  they are rarely needed anyways -- write a driver that polls for input just like all the other pieces of code.

Dear Frysinger:

 

Now I puzzle about how to use Uboot realize the choose item function like the BIOS do on the PC.

 

how to let user move  up and down,right or left to highlight the option choose an Item to do something.

 

Can you give some proposal?

if you mean a menu/config system, then u-boot doesnt currently support that.  it only supports a video console (like what you see on the serial console).
