Re: [Freeipmi-users] freeipmi command equivalent to ipmitool fru read/write <fru id> <file>

[Albert Chu]

I've got what I believe works in this branch on github

https://github.com/chu11/freeipmi/tree/frureadwrite

To build:

git clone https://github.com/chu11/freeipmi.git
cd freeipmi
git checkout -b frureadwrite origin/frureadwrite
./autogen.sh
./configure --enable-debug
make

There's more info the manpages, but I added the read/write into
bmc-device since I considered it an advanced niche need.  The basics
are:

bmc-device/bmc-device --read-fru=filename --device-id=num
bmc-device/bmc-device --write-fru=filename --device-id=num

Also added a --fru-file option to ipmi-fru to test anything you dump
out.
