problem :

ON the prototype, the customer use the  MCIMX6Q5EYM10ACD6AVT10AC (grade indus) without problem ,

  but on theProduction version  they used the iMx6  quad 1GHz ref MCIMX6Q5EYM10AC (grade commercial)  and 

and they have some problems . THe linux stops to run in  somes cases without raison .

    It is exactly the same Board between production and prototype board . .

  All DDR signals are corrects .

THe power comsuption is good .

temperature about 67 ° C

  Same soft on the both board ...


Following the SR request , they performed the DDR test +

power . IT seems thaht it is not hardware related but soft problem due to the

configuration .


They performed the DDR test :

  We performed the ddr test up to 1GHz without any problem reported.

After loading the config file, the bugs appears as before.





Could you please help us to determine the difference
between the both I.MX6 that could explain it ?



on the both board, they can not achieve the 1 GHz , only
800 Mhz .
