Part Number: SK-AM62P-LP
Other Parts Discussed in Thread: AM62P

Tool/software:

Hello,

I am using SK-AM62P-LP with Android SDK 10.0.1. I have referred to below link for MCAN however it does not work and I could not find a link for Android automotive SDK.

software-dl.ti.com/.../How_to_test_MCAN_on_AM62x.html


From what I understand from above link, dtbo overlay is needed. I have used tried as below but still I could not find a can0 interface when using ifconfig command. Kindly share steps (or) any document for enabling CAN-FD in android.

    I tried the steps mentioned in below link but still there was some issue loading m_can.ko. So finally I downgraded to Android 14(SDK 10.0) and removed all protected symbols from the list and now I am able to see can0 & can1 interfaces.

    Planning to check physical connections today but I am yet to locate pin diagram and config for starter kit.

    Below link to download design files does not work!

    I sent packets via J1 (3 pin) and it is received in can3.

    Strange! but it seems there is no vehical hal (or AIDL) listening to CAN interfaces. As far as I see there is no TI implementation of vehicle hal.
