All,

We are thinking of using serial port for image download. I browsed
this group for some pointers but I was not able to find any.

Can I download the nk.bin using serial port ? What are all the changes
that I should be doing ?

Any help guys.

Reg,
Venkatesh

The speed will be a problem, which will be very slow for NK. For the serial
downloading, the protocol should be realized in a simple way, which is like
usb downloading. How to process the incoming data in the serial port? When
to send ACK? This is all about protocol.

Speed is only an issue if he doesn't have time to wait. If the OS is very
small, it wouldn't be that bad.

Example code for serial download can be found in CEPC's sboot and
Platform\Common.
