Evaluating TSN RDB

raj2569 — Tue, 15 Oct 2024 12:17:41 GMT

Hello all,

I am new to NXP community and landed here to evaluate a TSN board for an upcoming TSN based switch project. I have seen three boards with TSN capability here (Not sure if I had missed any)

Of course all three are of different capabilities, and with varying price points. IS there any document comparing the capabilities of these three so that I can make an informed choice?

Also there are two operating systems for the devices:

Again how are these two different and what are the basis for choosing one over the other?

One more question, in the documents I can see a reference to felix. Is this related to the reference boards above?

LS1021ATSN board is the early product, it includes a regular LS1021A SoC and an external L2 switch (SJA1105TEL) with TSN features. LS1021A processor is just used to configure SJA1105TEL.

Probably You could consider new TSN silicon LS1028A, it consists a new TSN-enabled Ethernet controller with endpoint-specific features, as well as a new on-chip TSN switch.

For LS1021ATSN, you could use NXP released Real-time Edge Software.

For LS1028ARDB, you could use NXP released LSDK or Real-time Edge Software.

Both LSDK and Real-time Edge Software are free for customers.

Flex Ethernet and switch drivers are related with LS1028A processor.

Thanks @yipingwang for your kind answer.

If I choose LS1021ATSN over LS1028ARDB, given the price difference, what am I missing? If there is some documentation comparing these two solutions, I will be happy to read them. This is just for my due diligence and if there is a sufficiently strong engineering reason for my use case to use LS1028ARDB I will certainly use it.

PS: I am assuming these are the two TSN switch RDB available with NXP. Please let me know if there are other solutions I should be looking at.

Thanks

Please refer to section "Table 28. TSN configuration tools support on different platforms" in https://www.nxp.com.cn/docs/en/user-guide/REALTIMEEDGEUG_Rev2.4.pdf

Thanks! In the same document I can see the following table:

LS1028A has two models provided, If I buy LS1028A Reference Design Board which one will I be getting? ENETC or Felix Switch?

Thanks!

You will get both.
