例程运行结果错误C:\ti\mcu_plus_sdk_am64x_09_00_00_35\examples\drivers\mcan\mcan_loopback_dma,是不是这例程有问题啊?我这边啥也没改直接拿过来运行的,但是不行

nub 说:但是不行

您跑的是McSPI例程?mcan_loopback_dma例程可以在am64x-evm上运行。https://dev.ti.com/tirex/explore/node?a=VLyFKFf__4.12.1&node=A__AD2nw6Uu4txAz2eqZdShBg__com.ti.MCU_PLUS_SDK_AM64X__rN4Qml4__LATEST

之前图片给错不好意思 ,您给我这个网址说是可以运行,但是我这边实际把程序放到板子上面跑是出现错误的,我运行polling和interrupt是正常的

,

Shine:

请问使用的是什么板子?是am64x-evm板还是am64x-sk?

,

nub:

am64x-evm,AM6442
