The tftpboot command permits reading of files over a network interface
using the Trivial FTP protocol. This patch series adds the ability to
transfer files the other way.
Why is this useful?
- Uploading boot time data to a server
- Uploading profiling information
- Uploading large mounts of data for comparison / checking on a host
(e.g. use tftpput and ghex2 instead of the 'md' command)
Mostly the existing code can be re-used and I have tried to avoid too
much refactoring or cleaning up.
The feature is activated by the CONFIG_CMD_TFTPPUT option.
This has been very lightly tested on a Seaboard with a USB network
adaptor. It does handle block number overflow which removes any limits
on maximum transfer size. However, tftp-hpa does not seem to support it.
However, I might have a patch...
Changes in v2:
- Cope with block rollover
- Don't print amount of data transferred on each block rollover
