AM67: Can the CC-Link IE TSN + ISP function operate?

Hello Ito-san,

I need some time to check internally on CC-Link IE TSN support. I hope to come back with an update by Friday. Please kindly ping this thread if you did not receive a response by then.

In the meantime, have you looked at https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-am67/latest/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Network/CPSW-TSN.html as a guide on general TSN support for AM67?

Update: 

We currently don't have specifically CC-Link IE TSN support for AM67. However, from my understanding CC-Link IE TSN uses generic TSN with no special requirements, using 802.1AS and 802.1Qbv, 802.1cb. Only special requirement is extending .cb to 802.1cbdb " Ethertype based packet filtering for forwarding the CCLINK untagged packets to high priority queue instead of VLAN priority", with the rest of the 802.1 TSN standards remaining the same. Additionally, it looks like the 802.1cbdb amendment will be approved by 802.1cb as an "extended stream identification in addition to existing stream identification methods in .1cb protocol".

We support several TSN standards as indicated in this link.

ISP function operate on the AM67?

Are you asking about AM67A? ISP function is not available in AM67x only in AM67A.

Hi Daolin,

Thank you for your reply.

I'm inquiring about the AM67.
The datasheet mentions ISP, but is it not usable?

AM67x Processors datasheet (Rev. A)

Best Regards,
