Hi @arun_mozhi_thevan!

Unfortunately in general in i.MX93 the Cpu frecuency is managed by lpm (Low power Module) and we use the lpm driver in iMX93 and is the reason that we obtain the error using that command.

You can use the mhz command instead.

Hi @arun_mozhi_thevan!

Thank you for contacting NXP Support!


Try with the command mhz.

The result should be the next:
