#15 Can't read info about DIMM's
Hello oo community!
Lot of thanks for your work.
I have a problem - can't read info about DIMM's - ipmisample program returned very strange output:
INF: .1.20.111.0.0.0 fru.c(fetch_complete): Unable to decode FRU information
WARN: (32.4) entity.c(fru_fetched_ent_cb):Error fetching entity 32.4 FRU: 26
EINF: .1.20.110.0.0.0 fru.c(fetch_complete): Unable to decode FRU information
WARN: (32.1) entity.c(fru_fetched_ent_cb):Error fetching entity 32.1 FRU: 26
EINF: .1.20.112.0.0.0 fru.c(fetch_complete): Unable to decode FRU information

EINF: .1.20.113.0.0.0 fru.c(fetch_complete): Unable to decode FRU information
WARN: (32.24) entity.c(fru_fetched_ent_cb):Error fetching entity 32.24 FRU: 26
ipmitool retrive and decode info for this DIMM:

What is your suggestions and advices?
The FRU information must be in some format that OpenIPMI doesn't
understand, but ipmitool does.
DIMM FRU information usually comes encoded with SPD, and looking at the
OpenIPMI version of the decoder, well, it leaves a lot to be desired.
It's pretty much wrong, and it was written long before DDR3, DDR4, etc..
I didn't write the original code, so I don't know that much about it.
So someone need to rewrite that code to comply with the standards. Do I
have any volunteers?

Hello Corey.
As far as my workaround will be tested I can share my solution with you.
