How to identify which i.MX8M type a program is running on ?

[NicolasP]

Hi,

On a i.MX 8M (a i.MX 8M Plus to be exact), how can the software know which chip it is currently running on ?

i.MX 8M, i.MX 8M Mini, i.MX 8M Nano, i.MX 8M Plus... ?

Also, how to get the revision number ?

Best regards,

Nicolas

Hi @NicolasP 

Please check cat /sys/devices/soc0/soc_id and cat /sys/devices/soc0/revision

Hi @Harvey021 ,

Thanks for your reply but this does not answer my request.
I'd like to know how to identify the SOC at low level programming (in the boot process).
Which registers of the chip do I have to read ?

Best regards,
Nicolas

Hi @NicolasP 

For example i.MX8MP.  see the register 5.1.8.39 DIGPROG Register (CCM_ANALOG_DIGPROG) in reference manual.
