Does LPC54018 support credit based shaper, if yes, how can I enable it ?
@william_jiang would you mind assign a guy support this case who knows Ethernet IP well?
The end customer is Microsoft
Hi Magicoe,
any update on this topic?
is there any special requirement for enabling CBS?
we run traditional iperf test on queue enabled CBS, and expect the throughput are limited by the idle slope. Is that reasonable?
Hi,
I do not think that the Ethernet module of LPC54018 supports credit based shaper.
Hope it can help you

Hi,
have you received the project I send out by e-mail?
thanks.
Hi, Wang,
Can you clarify your requirement? do you hope that NXP engineer can help review your code, or you do not know how to use CBS feature of ethernet and hope to get support.
Pls clarify your requirements.

1. if LPC54018 support CBS?
2. if yes, how to enable it.
if the question 2 is too complicate, let us ignore it.
I think just to clarify if LPC54018 supports CBS, that will be good enough.
Hi, Wang,
This is the AE reply "LPC54018 supports CBS", but we have not the code to support the feature in SDK driver. I am sorry.

Thanks for the information.
I just created the code based on the reference manual : UM11060
LPC540xx/LPC54S0xx User manual.
and there are actually credit based shaper register on LPC54018
Hi,
Obviously, from the UM11060.pdf, the LPC54018 supports CBS, I will create a ticket for AE team, pls clarify your requirements so that the AE team engineer can help you
If you require us to review the code, pls post it here or send to my personal Email if it is confidential.

ok, i can send you the CBS code to review, can you tell me your email?
Do you have examples that show how to use CBS and how to validate the CBS function?
Hi,
I tried to contact you, but it appears that your Email address has issue. Pls check if the spelling is correct.

thanks for the effort, that email can't be accessed.
i will leave my personal email here: wenflower@163.com
Hi, Wang,
I appologize for the wrong information, I am not familiar with the CBS (credit based shaper) protocol.
We will give you a response after we discuss with AE team engineers.
