Hi Rob Herring,
I am just do a function testing on Atmel sama5d3xek board. And a small
comment as following.
Btw, do you test to transfer big size file. I try a file bigger than
100MiB, it will hang. However use DFU or RNDIS don't meet this issue.
How much RAM do you have? It will happily download into the end of RAM overwriting u-boot if loadsize is not set. DFU at least has its own buffer size configuration.
I really have to wonder ... why does android not use DFU instead and instead forces us to take in yet another (fourth ? ... CDC ethernet, DFU, Thor, Fastboot) usb image download protocol someone invented without cooperating with the rest of the community on a common and functional solution? Sigh :'-(
