How to add a NAND partition in the kernel for LS1043ardb

[hoanguyen]

I am adding a new NAND partition for the ls1043ardb (SDK 2.0) in the u-boot as follows:

/include/configs/ls1043ardb_common.h

#define MTDPARTS_DEFAULT "mtdparts=60000000.nor:1m(nor_bank0_rcw)," \

            "1m(nor_bank0_uboot),1m(nor_bank0_uboot_env)," \

            "1m(nor_bank0_fman_uconde),40m(nor_bank0_fit)," \

            "1m(nor_bank4_rcw),1m(nor_bank4_uboot)," \

            "1m(nor_bank4_uboot_env),1m(nor_bank4_fman_ucode)," \

            "40m(nor_bank4_fit);7e800000.flash:" \

            "1m(nand_uboot),1m(nand_uboot_env)," \

            "20m(nand_fit);spi0.0:1m(uboot)," \

            "5m(kernel),1m(dtb),9m(file_system)"

Changed to:

#define MTDPARTS_DEFAULT "mtdparts=60000000.nor:1m(nor_bank0_rcw)," \

            "1m(nor_bank0_uboot),1m(nor_bank0_uboot_env)," \

            "1m(nor_bank0_fman_uconde),40m(nor_bank0_fit)," \

            "1m(nor_bank4_rcw),1m(nor_bank4_uboot)," \

            "1m(nor_bank4_uboot_env),1m(nor_bank4_fman_ucode)," \

            "40m(nor_bank4_fit),10m(new_nand_part);7e800000.flash:" \

            "1m(nand_uboot),1m(nand_uboot_env)," \

            "20m(nand_fit);spi0.0:1m(uboot)," \

            "5m(kernel),1m(dtb),9m(file_system)"

My questions are:

1) Is it the right way to add new partition in u-boot?

2) I don't find much information in the kernel for adding new partition rather than the following 2 files:

arm64/boot/dts/freescale/fsl-ls1043a.dtsi and fsl-ls1043a-rdb.dts

How can I add new partition in kernel?

thanks,

Hoa

hi Hoa,

I've the same question, do you have any progress on this?

NXP SDK for LS1043a uses new image source format.

Look at the following pages:

https://casper.berkeley.edu/svn/trunk/roach/sw/uboot/doc/uImage.FIT/source_file_format.txt

Have a great day,
