Part Number: TDA4VM

Hi TI,

I am using PSDK 7.3 Linux with TDA4vm/J72EXCPXEVM.

I want to use main_mcan0/2 instead of mcu_man0/1 on Linux.But it was disabled in dts/dtis.

Could you please send me a guide on how to enable MAIN_MCAN0 and MAIN_MCAN1 in the device tree?

Regards.

    Hi,

    Can you please use the attached patch to enable main_mcan0 and main_mcan1 from Linux.

    When using this, please make sure that no other core is already trying to enable these two mcan instances.

    Hi Karan.

    Thanks for your quick reply.

    We tested main_mcan0 and main_mcan2 with your patch and it works without any problems.
