Re: [Redboot] USB configuration in redboot (version redboot_200732) to make IMX31 ADS as USB client.
Dear Frank,
I Have added USB slave device driver & Common USB slave USB
pakage to configuration. and when I make, in build/usb directory i am
able to find io_usb_slave_usbs.o , usbs.o.d , libtarget.a.deps ,
libtarget.a.stamp files . I have downloaded the Redboot.bin through
TFTP to my board and once i got the Redboot prompt in minicom running
on Linux host, I have connected USB slave port to Windows Test PC. but
nothing was detected.
Frank,
Can u please tell,
How to add USB descriptors to your Redboot build?
How to make USB device to be polled?
Thank you very much for the time.
