[LS1043A] Verify ITS Fuse state

samfuxu — Fri, 21 Jun 2024 15:23:14 GMT

Hello,

I'm trying to verify the state of the Intent To Secure fuse on LS1023A and LS1043A based boards.

After provisioning the fuse configuration and U-Boot image (which does not give any command line interface to the user), how can I verify the state of the fuses and in particular the ITS fuse ? Is it feasible via JTAG ?

Hello @SebastianG

Do you have any update on this topic?

Which procedure can follow to verify ITS status via JTAG?

I am looking to something similar to: https://community.nxp.com/t5/Layerscape/How-to-detect-if-device-was-fused-secure-boot/m-p/1314528

Thank you,
