hi.

 

i'm finding a 64bit device unique ID in imx6 board.

 

i found OCOTP_CFG0, OCOTP_CFG1. the chapter 46.5.10, 46.5.11 explain that they are each 32 bits unique IDs in IMX6DQRM doc.

 

1. can i read OCOTP_CFG0, OCOTP_CFG1 with physical address (Address: 21B_C000h base + 410h offset = 21B_C410h)?

 

2. it could be read only secure mode ? or non-secure mode?

 

Best regards.
