BR_CID does not match ECID

Autonomous Machines Jetson & Embedded Systems Jetson AGX Orin

Hello,
I am seeing different BR_CID and ECID values.

I checked the BR_CID by putting the Jetson in forced recovery mode:
sudo ./tegrarcm_v2 --new_session --chip 0x23 0 --uid
BR_CID: 0x80012344705DD3E310000000030082C0

ECID was read using the below command:
cat /sys/devices/platform/efuse-burn/ecid
ECID: 0x0x00000004 705dd3e310000000030082c0

I applied the patch provided on this thread - Reading BR_CID from kernel

Thanks!

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Hi shivam11,

It seems the expected result to me since ECID is gotten from BR_CID with masking the first 28 bits.

May I know what’s your use case for ECID?
