Hello Community,

How to Configure configure DDR3L RAM on fresh FRDM board?? 

As per my knowledge I don't have to do an changes in dts or anywhere in BSP. If anything need to be done in BSP code please guide me.

Please provide pointer on configuration part.

Thanks,

Shyam

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

Have a great day,

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,
