Intel PAC (Arria 10) problem with FIM/BMC - Intel PAC (Arria 10) problem with FIM/BMC 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... $ lspci | grep 09c4 01:00.0 Processing accelerators: Intel Corporation Device 09c4 $ sudo dmesg -T |grep avmmi [Wed Sep 29 08:44:53 2021] avmmi-bmc avmmi-bmc.2.auto: avmmi_send_one no response count [Wed Sep 29 08:44:53 2021] avmmi-bmc avmmi-bmc.2.auto: avmmi_bl_version failed bmc comm -110 [Wed Sep 29 08:44:53 2021] avmmi-bmc avmmi-bmc.2.auto: avmmi_probe failed to get BMC BL version.

Replies: Re: Intel PAC (Arria 10) problem with FIM/BMC When upgrading BMC, the USB cable is required. Replies: Re: Intel PAC (Arria 10) problem with FIM/BMC Update: missing USB cable resulted in erroneous BMC update =>fixed now.
