Hi mike,
please do not top post
It seems there's a big difference between my current project and u-boot common usage. I can only enjoy the patch myself now
i want to get a packet from usb/network, then redirect it to can bus. So blocked write/read of can is not allowed.
what's wrong with receiving data over usb/network into external memory, then transferring it over CAN ? this is typically how things are done -- load an file over the network and once it is complete, operate on it (write it to flash, boot it, whatever). -mike

It seems a good method, especially when we download a file from computer. But i'm afraid u-boot doesn't support upload well. Basically I agree blocked CAN read/write can fulfill my requirement, even though it's not so flexible as what i wished.
