  Hi,

  When I use the Ubuntu image, the system boots without any problem. But when I want to use a Yocto image generated following the tutorial it doesn't. I have connected the board to my computer to see what's happening with picocom and I get that :

  Ubuntu image :

  

  Then it boots without any problem.

  Yocto image :

  

  Is it normal that there is a difference between the DRAM rates ?

  Hi Julien,

  Could you please tell us, if you're using uboot from our github, or you built your own uboot?

  @Allumallu Susmitha I'm using the Yocto build tutorial for IMX8MP in your documentation.

  @Allumallu Susmitha where do I configure the number of RAM gigs in the Yocto building process ?

  Hi Julien

  https://github.com/ADLINK/meta-adlink-nxp/wiki/01-1.-Build-Yocto-Image_imx8mp

  Follow this documentation step no. 2.2 Required Setting in conf/local.conf

  $ vi <build_dir>/conf/local.conf
  
  # sets the LPDDR4 DRAM size, available options are: LPDDR4_2GB, LPDDR4_2GK, LPDDR4_4GB, LPDDR4_8GB
  UBOOT_EXTRA_CONFIGS = "LPDDR4_2GB"

  @Allumallu Susmitha it could be a good idea to update the tutorial on the I-Pi documentation...
