Is the branch, 201811 (Broadcom SAI 3.3 GA release) supporting the Broadcom TD3 chip yet?

[pollyhsu2git]

Description
Based on the Broadcom SAI release note, the Broadcom SAI 3.3.X.X supports the Broadcom TD3 chp. However, based on our testing here on the branch, 201811, it seems NOT

We just want to clarify that:

1. Whether SONiC has any plan to support the Broadcom TD3 chip?
2. If YES, when will it be?

Steps to reproduce the issue:

1. git clone the SONiC code base, and checkout the branch, 201811.
2. Do the porting of our TD3 model (AS7726-32X) based on the SONiC porting guide.
3. The syncd initialized failed with the following error messages:

Hi,
Below logs suggest cancun files are missing and that could be root cause of your issue. Are they available on SONiC? If not, you may want to get in touch with Broadcom marketing.

Um, On SONiC, the Broadcom SAI 3.3 GA release is built / released by MS co-working with Broadcom. We are trying to clarify whether the Broadcom TD3 chip family will be supported on SONiC (MS / Broadcom) by high-lighting the root cause upon our debugging.

Hi
I'm porting Broadcom TD3 in SAI 3.3.4.3-1 and get some error message after port was inserted

I checked M0 firmware was loaded

Have I met the same issue? or I'm missing some configuration need to set?

No. SAI 3.3 doesn't have TD3 support. Sorry for taking so long to answer.
