Hello all, 

 

I have made linux image for IMX8MPLUS with the help of Yocto and flash the image on a custom board which is using IMX8MPLUS processor (Image made for IMX8MPLUS will be required for that board) when i flash that image on IMX8MPLUS-evk Board then it works fine but when i flash that image on that custom board it does'nt boot properly and showing below  errors .  It is not reaching till user prompt as in evk board appears and showing failed to load regualtory.db file. 

I am putting logs here only of errors and complete file of log i am attaching in attachment.
