Intel PAC (Arria 10) problem with FIM/BMC

[JensDo]

Hi,

I tried updating an DK-ACB-10AX1152AES board to match the newest FIM/BMC required by Intel's 1.2.1 SDK (it was at 1.1 beta status before I started)
The FIM seems to be now at 1.2-compatible level (using the Bittware II TKL), but something is strange with the BMC.
Here a few pointers...

Any ideas about the root cause of this behavior, and how to fix it?

Update: missing USB cable resulted in erroneous BMC update =>fixed now.

When upgrading BMC, the USB cable is required.
