[TDA4VM]mcan demos

Other Parts Discussed in Thread: TDA4VM

Hi,

Now we have some TDA4VM/J721EX boards and 06_01_00_15 sdk.

-1-

Is there any examples running on mcu2_1 where we can control the MCAN0~13?

We want to test the links of MCAN0 and MCAN2 which are exposed on the EVM.

If the links are OK, we want to connect some can devices to the EVM through MCAN0 and MCAN2. Do you have any demos?

-2-

We found there is no driver for CAN on TDA4VM/J721EX as of now. Would you provide linux driver of MCAN in the next version of SDK?

If we want to control our can devices in Linux, what should we do? We need to develop drivers by ourselves?

-3-

I found there is a board test demo in pdk/packages/ti/board/diag/mcan, but the demo only can be built for mpu1 and mcu1_0.

The test demo cannot run on mcu2_1?

How can I use this demo to test MCAN0~13?

I found something as shown below in the makefile of mcan_board_diag. I think the sdk lack of .asm and .lds files of mcu2_1, is it right?

Where can we get the files?

    Hi Subin,

    Please find my responses as follows:

    1. The sample application for MCAN is available in PDK and it is available here: 'pdk\packages\ti\csl\example\mcan\mcanEvmLoopback'. This sample application runs on MCU1_0 as well as MCU2_1 and uses MCAN modules from MCU and MAIN domains.
    2. MCAN driver is available in PDK but it is not available in Linux. May I know the reason behind controlling MCAN through Linux? Can you please use PDK MCAN driver?
    3. You can use the MCAN sample application instead, as mentioned in the first point.

    Thanks & Regards,
    Vivek Dhande.
