AM5716: How to control CAN1 on Linux and CAN2 on SYS/BIOS systems?

Hello Zhicheng,

Please read the TRM Interconnect section, I think theoretically this is possible based on the connections available : 

Linux would be controlled by the A15 and this has connections with both the L4 _WKUP and L4_PER2_P3. (See the below image for the interconnect paths to dcan1 and dcan2)

As to the other cores, you can refer to chart, the "C" denotes that a functional path exists.

With regards to the code, Please see the corresponding SDK documentation for any existing guidance: 

• Linux - https://software-dl.ti.com/processor-sdk-linux/esd/AM57X/09_02_00_133/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/DCAN.html
• RTOS - https://software-dl.ti.com/processor-sdk-rtos/esd/AM57X/09_02_00_00/exports/docs/rtos/index_device_drv.html#csl-fl-examples

Best,

Josue
