Enabling forward traffic on switch ports from DPSW (DPAA2) without running OS

rgallais — Wed, 27 Apr 2022 10:05:33 GMT

Dear Community,

From my trials, it seems that applying DPL from U-Boot is not enough to enable the DPSW and enable forwarding traffic on switch ports from DPSW and I needed to run the following command "ip link set eth<N> master <brX>" (under Linux) to do it.

Is there a way to enable forward traffic on switch ports from DPSW (DPAA2) without running OS ?

It would be great to do so from DPL configuration but I haven't found how to do it from LSDK UG document.

Regards,

Please get mc_utils source code folder in flexbuild_lsdk2108/components/firmware/mc_utils/.

Please refer to dpl file in mc_utils/config/ls2088a/LS2088A-RDB/custom/dpl-eth-dpsw.0x2A_0x41.dts.

Thank you for your inputs ! I succeeded to deploy the DPSW with forward traffic enabled under U-Boot without running Linux.
