Thanks for reply! Is there a reason why secure boot isn’t supported for LX2162a CLEARFOG 18\_9\_0? Also 3200 MHz DDR3 not supported only 2900 MHz and BUS is set to 650 MHz. Have this options major reasons? ---

The changes in the max memory and bus speed are changes NXP has released for the product lineup. We have not received an official statement regarding the change in the spec, but my assumption is that it has to do with NXP’s long term testing, and requirements for support for 10+ years. None of our developer builds support secure boot. It is not specific to the 18\_9\_0 configuration. ---

Ok thanks for your explenation.

I will test and get back to you. The latest BSP does have the ability to have linux re-create the interfaces setup in the mcbin .dpc. We are still working on testing this and documenting it. This will remove the need to run ls-addni every boot. ---

Please test the latest BSP images. We have verified them with a 25Gbps fiber module and they detect and function properly. ---

I can’t bring up the 8x1 Gbps NIC and also not SFP+ which I brought up with the old branch. I will test my SFP28 optics later ---
