Change u-boot configuration file for your SDRAM. Look at attached file. These file are u-boot configuration files for the FRDM-LS1012Aboard .This file is available in u-boot source folder. Use the following path:

QorIQ-SDK-V2.0-20160527-yocto/build_ls1012afrdm/tmp/work/ls1012afrdm-fsl-linux/u-boot-qoriq/2016.09+fslgit-r0/git/include/configs

Look at u-boot source code. U-boot provides DDR3L initialization. See attached files. These files are available using the following path in SDK 2.0:

/QorIQ-SDK-V2.0-20160527-yocto/build_ls1012afrdm/tmp/work/ls1012afrdm-fsl-linux/u-boot-qoriq/2016.09+fslgit-r0/git/board/freescale/ls1012afrdm

Hi pavel,

I have checked those file and I can see some initialization parameters as well but I don't see any size related parameters.

So my query is What changes to be done in BSP If I increase RAM size to 2GB which is Presently 512MB on FRDM-LS1012A board.

NOTE : There is one parameter 'CONFIG_SYS_SDRAM_SIZE' but I don't know how to manipulate

Thanks,

Shyam
