为我的Beaglebone黑色设置CAN时,我似乎遇到了问题。我已经更新到最新的映像“ AM3358 Debian 10.3 2020-04-06 4GB SD IoT”,并已从SD卡启动,更新了U-boot覆盖,并具有在p9.19 / p9上启动端口的功能.20以反映可以,但我在跑步时得到了
debian@beaglebone:~$ dmesg | grep -i can
[ 1.226463] CAN device driver interface

任何人都可以向我解释为什么我收到以下消息“找不到任何crtc或尺寸”
使用内核版本-4.19.94-ti-r42
编辑:我还用SD卡上的图像刷新了eMMC,仍然出现相同的错误。
