Hello folks, I am trying to optimize the boot time of my system with Waveshare CAN cape.
I got CAN1 (P24,P26) working by setting in uEnv.txt: uboot_overlay_addr0=/lib/firmware/BB-CAN1-00A0.dtbo It is also possible to use config-pin (I later noticed that this is a feature of cape-universal) to enable CAN1 as explained in this link: https://www.thomas-wedemeyer.de/beaglebone-canbus-python.html While trying to reduce boot time, I realized that disabling cape-universal significantly reduces boot time. However when I disable it, CAN bus stops working and I get the following error when trying to enable it: debian@beaglebone:~$ sudo ip link set can1 up type can bitrate 500000 Cannot find device "can1" Is it possible to use the CAN interface without cape-universal? How can I avoid unneeded hardware initialization to reduce boot time?
