In my project, I need add usb keyboard support in uboot for recovery purpose.
I have success followed RCN’s uboot build instructions to build uboot for beaglebone black.
Then I try to modify the configuration to add usb keyboard support.
I add CONFIG_USB_KEYBOARD then build.
The build is ok but after I download MLO and u-boot.img into emmc, usb keyboard do NOT works.
My operation is:
1, Press space to interupt auto boot of uboot.
2, > usb start // It shows success to found my dell keyboard
3, > setenv stdin usbkbd
then I click my dell keyboard which connected to bbb, nothing appear in console, also my serial console cannot input characters too.
Another problem is about CONFIG_CONSOLE_MUX, when I enable it, uboot just stuck after echo about 5 lines after uboot.img start.
I have no idea about these two problem, is someone successed to use usb keyboard in uboot?
