您好 这里有一些可能的原因和解决方法：1. 检查硬件和软件配置 确认硬件支持：确保您的TCAN4550硬件以及相关的接口（如PCI-E、USB等）能够支持5Mbps的CAN FD通信。驱动程序更新：检查并更新Linux系统上的CAN驱动程序和TCAN4550的相关驱动，确保它们是最新版本且支持CAN FD。配置检查：确认...
tcan4550调试,从linux-5.14版本获取了tcan4x5x的驱动,调试发现如下问题: 1、设备驱动在读取ID作为匹配时,调用tcan4x5x_read_reg,此函数在地址位中对所有地址偏移加0x1000,发送地址数据为0x41100001,而根据手册实际应该为0x41000001,修改后读取ID正常; 2、根据m_can_check_core_release()中读取ID后的逻辑判断,...

I am not too familiar with the Linux drivers that are not directly related to TCAN4550. If possible, let's keep this discussion high level: register values, desired configurations, electrical observations, etc. During test 1, can you read the values of the interrupt r...

我的理解是、现有的 tcan4x5x Linux 驱动程序本质上是以相同的方式构建的、并将 M_CAN 驱动程序包装到全面控制器件所需的附加 SPI 寄存器。 为了提高效率、最近对此驱动器进行了一些修订。 此致、 乔纳森 admin2 年多前 TI__Guru***1930300points 请...
The Linux driver has been included into the Kernel and the Linux community is responsible for driver support. This is a device support forum and I can help you with device specific issues, but I will not be of much help if the issue is with the linux driver. ...
