How to get UID/Serial Number of MCU in Yocto ?

[toanjunifer]

Hi,

I'm trying to get unique ID or serial number of something else which unique for each MCU. 

For example: I have 2 iMX6S boards.  I want to determine that how are they different via Linux command? 

Thank you so much.

Hi Toan

one can read uid fuses (can be found in Chapter 5 Fusemap

i.MX 6Solo/6DualLite Applications Processor Reference Manual

check for userspace access
