LS1046a RDB board uses MTA18ASF1G72AZ (UDIMM) DDR SDRAM.
We changed the DDR SDRAM to MTA18ASF1G72HZ (SODIMM) to create a new board.
In this case, I would like to know which part of the U-boot and kernel source should be changed in the SDK used by the ls1046a RDB board.
If you know, please answer.
Find the /drivers/ddr/fsl folder in u-boot source code.
Change the ddr4_dimm_params.c file in this folder.
Have a great day,
Pavel Chubakov
Usually additional configuration is not needed.
The LS1046ARDB u-boot uses SPD for reading DDR parameters.
It provides initialization of DDR using SPD.
Linux does not initialize DDR. Linux uses DDR configuration from u-boot.
Have a great day,
