[rohit_k]

Hello community,

We are using custom board based on i.mx8m-mini.

Yocto version :  Zeus-fsl-5.4.3-mx8mm-v1.1

while booting this error occurs : "ddrc freq set to low bus mode" .

Observation about this error : This error not comes every-time, sometimes board boot properly and sometime this error happens.

Could you please tell us what is the reason for this error and how to resolved it ?

Please find attached log file.

Thanks and Regards,

Rohit Khatal
