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

NicolasP — Thu, 11 Aug 2022 12:05:21 GMT

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

Best regards

Harvey

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.
