Retrieve CPU ID on F28377D

rony macabo56

Hi,

On F28377D, Is there a way to know at runtime on which processor, my application is running? without having to add #ifdef CPU1 statement?

What i need it's to know at runtime, by reading a register on which processor the part of the application is running, so that i could perform load balancing.

Please, i do not find some register like that in MPIDR datasheet? is there one? or another way to proceed?

Thanks in advance,

Best regards,

Rony

Rony,

In F2837x devices, address 0x7026D has CPU ID field at bits 7:0.
For CPU1, value should be 1. For CPU2, value should be 2.

Thanks and regards,

Rony,

I checked with our team on this and got the confirmation that this info will be documented in the next revision of TRM.

Thanks and regards,
