modifying rcw file for lx2160ardb-rev2

[shivam_kumar]

I am booting the lx2160ardb board through eMMC card, and want to make changes EC2_PMUX =1  to rcw and deploy it so that i can do gpio testing. i am doing it according to lskd only but not able to do it.

i want to know in which rcw file should i make the changes and how to deploy it since it has not been mentioned in lsdk

I am using UG10081_LLDP_6.1.55_2.2.0.pdf , and have checked the manifest file . after making the changes to rcw i have regenerated atf image using new rcw through $ bitbake qoriq-atf command .  i have copied the new images to boot section of emmc card. but what should be the next steps?

$ source build_lx2160ardb-rev2/SOURCE_THIS

$ bitbake rcw -c cleansstate

$ bitbake rcw -c patch

Please go to rcw source code folder tmp/work/lx2160ardb_rev2-fsl-linux/rcw/git-r0/git/

and modify file lx2160ardb_rev2/XGGFF_PP_HHHH_RR_19_5_2/rcw_2200_750_3200_19_5_2.rcw

$ bitbake rcw

$ bitbake qoriq-atf -c cleansstate

$ bitbake qoriq-atf

After copy atf image to boot location, then run the following command to boot from emmc in u-boot.

=> qixis_reset emmc

I assume that you are using LSDK 21.08.

Please refer to configs/board/lx2160ardb_rev2/manifest

rcw_emmc="firmware/rcw/lx2160ardb_rev2/XGGFF_PP_HHHH_RR_19_5_2/rcw_2200_750_3200_19_5_2.bin"

Then execute the following procedure

$ source setup.env

$ flex-builder -c rcw -m lx2160ardb_rev2

Please modify components/firmware/rcw/lx2160ardb_rev2/XGGFF_PP_HHHH_RR_19_5_2/rcw_2200_750_3200_19_5_2.rcw

The rebuild rcw and atf image:

$ flex-builder -c rcw -m lx2160ardb_rev2

$ flex-builder -c atf -m lx2160ardb_rev2 -b emmc

Then you will get emmc ATF image bl2_emmc.pbl and fip_uboot.bin in build/firmware/atf/lx2160ardb_rev2/, please deploy them to emmc card.
