LLCE CAN2CAN Enable Time Issue

[qifa]

We use the Goldvip system and flash Goldvip-gateway.bin to implement the LLCE CAN to CAN conversion function. However, it takes about 15 seconds for the board to forward CAN normally after being powered on, which is too long for us. How can we optimize this startup readiness time

Hello, @qifa 

Thanks for your post.

GoldVIP provides a reference vehicle integration platform. It integrates NXP standard and reference software, along with open source and third-party software to provide an evaluation, development and rapid prototyping platform.

As a result, there are a lot of services/software running on the system, the default gateway routing is complex and need run both M core and A core side application, which may cost some time for booting the whole system. 

Typically, it is mainly caused by the A core side booting(TFA, Xen, etc.),as a result, maybe optimization could be done on removing some of the functions and some other common method for accelerating Linux boot could also help.

M核的启动和A核也有关系吗

您好

抱歉从之前的描述，并不太清楚您具体的使用方式，如果您指的的是如下默认的方式的话，需要两边同时启动正常后再做CAN 帧的转发

hi  您好，我的使用方式是用官网的fsl-image-goldvip-s32g274ardb2.sdcard刷写系统，然后在EB上配置LLCE CAN->LLCE CAN的转发规则，按我理解的是走的是fast path。这样的使用方式也是需要A核和M核都起来后才能够开始CAN的转发吗
