S32G3 LLCE CAN2CAN Fail
星期二
1,898 次查看
各位NXP专家，大家好！
背景信息：我的项目现在需要使用 LLCE 的 CAN2CAN 路由功能，从 BCAN1 接收消息将其路由到 BCAN2，绕过 Autosar CAN 通信协议栈。我已经按照手册配置了 EB，但测试后发现没有消息被转发。我的 LLCE 固件版本为 S32G_LLCE_1_0_7。
调试后发现，CAN驱动初始化正常，路由表也设置正确，TXMB也足够。LLCE固定也已成功加载。所以我不知道问题出在哪里。请问您能否指导我如何进行故障修复，以及是否有任何合理的建议？

Hi,Chenyin
Yes, I want to stop the forwarding of a certain port in the CAN2CAN operation. Normally, after receiving the 0x123 message on BCAN1, it is directly routed to BCAN2 for transmission. Now (assuming there is such a switch), if the routing is turned off, BCAN1 stops forwarding the 0x123 message, but BCAN1 can still receive other messages normally. Simply turning off its routing function is sufficient.

Hi,
1.We are using MCAL version RTD_4.4_4.0.2 and our own design board.
2.Thank you for your reply. The problem has been solved. Reducing the TXMB value used for routing on the target controller solved the issue; 16 appears to be the maximum TXMB value for each CAN controller.
3.I'd like to ask further: is there a way to disable the routing function of a specific CAN controller? Could you provide a relevant function or EB configuration option?
