serial number on digi Digi ConnectCore 6UL

0 votes

On the module I have SN:IXXXXXXXXXXXX, can I read this number from linux?

Is this the number that shows in /proc/cpuinfo | grep Serial?

I have implemented reading serial number from /sys/fsl_otp/HW_OCOTP_CFG1 and /sys/fsl_otp/HW_OCOTP_CFG0 but this number is different that written on the Imx6ul module.

Forgive me so simple question but I can't check it by myself. I have "opened" devices so /proc/cpuinfo | grep Serial returns me 0000000000000000. I want to be sure before closing device.
