Part Number: DRA821U-Q1
Other Parts Discussed in Thread: DRA821

Tool/software:

Can I use 18 CAN interfaces on DRA821 simultaneously?
We are trying to use 12 of them simultaneously on our development board, but only 6 are working.
Could it be a design error? Are there any restrictions on the CAN interfaces that can be used simultaneously on the DRA821?

Hello,

There are no such restrictions that only 6 will work out of 12.Are you using default CP board or custom board? No design issues reported .

My board is custom board. DAR821 has 18 pcs cans. According to you, 18pcs can be used at the same time? Clearly confirmation is required.
