PCI Express x4 Device Support
#2
Sorry, I should have posted my progress on these boards earlier.
 
I have two variations of the LSI Logic 9211-4i SAS RAID Controller working in two systems with Rockpro64's. 
 
One is the stock LSI 3/4 length board which is available on Amazon, eBay, etc.  This is a 4x board with a SAS connector out.

I'm using this board's SAS out port to the SAS in on an Intel RES2SV240 RAID 24 port SAS Expander Card.

From the expander I can address up to 20 sata drives or more SAS expanders.  I have this working in IT mode with Ayufan's recent (last month) Openmedia vault build. Thank you - Ayufan.  This is running in a re-claimed mini tower case with the re-claimed 300 watt power supply. I have tested and accessed twelve (12) drives through Linux and OpenMedia Vault with this build.
 
The second system is using a 1/2 length variation from Crossfield - same LSI 9211-4i chipset re-designed for 1/2 length.

I have this in a custom 4 drive NAS enclosure using 3d printed & MakerBeam components

Thanks again - Ayufan. It is running off an external power supply (Meanwell 160w) to a matching internal pico-power supply. That cleans up and distributes sufficient power to the drives, boards and fans while being ~90% efficient so the system idles around 22watts.  All these boards, 9211, SAS Expander, & RockPro have heatsinks that require air flow to be effective.  I have two in push-pull on the NAS and a couple in the mini-tower.


Both cards booted directly with the Openmedia vault builds. There are "oh-by-the-ways" however which are probably a function of my super-limited linux knowledge.  

While these versions of Linux recognize and effectively support the boards, I cannot get any version of the SAS2Flash, SAS2IRCU or LSIUtil to run from the command line.  MPT3SAS and MPT2SAS (drivers?) both load at bootup but I can't re-flash the boards while installed in the RockPro64 nor can I load any BIOS/firmware app to configure the boards in IR (integrated Raid) mode.  IT mode is working fine with OpenMedia vault but I would like to benchmark and experiment with the IR mode.  
 
Any suggestions or workarounds would be appreciated.
