Other Parts Discussed in Thread: AM62P
Tool/software:
Hi,
I attempted to enable CAN support using a device tree overlay, following the Android 15 documentation provided here:
https://software-dl.ti.com/processor-sdk-android/esd/AM62PX/10_01_01/docs/devices/AM62PX/android/Application_Notes_dtbo_support.html#android-dtbo
I used the following commands:
=> env set adtbo_idx 9
=> saveenv
=> reset
Although the device booted successfully, I was unable to see the CAN interface listed when running ip link show.
