--- Comment #2 from spork@bway.net ---
Still seeing this as of FreeBSD 14.3.

Same error on CLI, same error in dmesg:


[root@crate /home/spork]# mprutil flash save firmware lsi-orig-fw
mprutil: Fail to save firmware

mpr0: mpr_user_command: unsupported parameter or unsupported function in
request (function = 0x12)
mpr0: mpr_user_command: unsupported parameter or unsupported function in
request (function = 0x12)

adapter info:

[root@crate /home/spork]# mprutil show adapters
Device Name           Chip Name        Board Name        Firmware
/dev/mpr0             LSISAS3008       LSI3008-IT        10000100

I'm aware there may be other methods, but I was not successful in tracking down
any additional tools on Broadcom's site.
