Upload firmware through TFTP on REDFISH interface.

[Xiaochao Ma (马小超)]

Hi, all.

I'm trying to update firmware using REDFISH interface.
It can successfully upload images through TFTP on the BMCweb.
However, the firmware upgrade command in
https://github.com/openbmc/docs/blob/master/REDFISH-cheatsheet.md
failed.(Through TFTP method)
The TFTP command here is not configured.
The results of the command are as follows:

$ curl -k -H "X-Auth-Token: $token" -X POST https://${bmc}/redfish/v1/UpdateService/Actions/UpdateService.SimpleUpdate -d '{"TransferProtocol":"TFTP","ImageURI":"obmc-phosphor-image-fp5280g2-20190924042243.static.mtd.tar"}'
  Not Found

How should the address of TFTP be configured?
