T4240: CPU ID: Is there any way to mark the CPU if there are more than one T4240 on the board?

[carlpeng]

Hello,

If there are more than one T4240 CPU on the board, are there some ways to distinguish the T4240, for example, are there reset pins to configure the order of the T4240 CPU, and after power on, can read the configured ID through reading a register in the OS?

Thank you,

Carl

It is possible.

Please refer to the QorIQ T4240 Reference Manual, 4.6.3.2 General-purpose input.
