6.11.1.2 Bootloader with display feature has NXP Yocto SDK's steps; ". ./setup-env -m ls1028ardb -b build_ls1028ardb"


6.11.1.2 Bootloader with display feature
----------------------------------------

To enable Display Transmitter Controller, it needs to use the rcw_1300.rcw rcw file, and set HWA_CGA_M3_CLK_SEL to 2.
And then build the ls1028 bootloader file(firmware_ls1028ardb_uboot_<boot-type>.img).

Detailed steps as below:

Refer to section 7, add necessary configurations in local.conf firstly.

Open file <project-path>/layers/nxp-ls1028/conf/machine/nxp-ls1028.conf, and then set RCW related
variable as below.
RCWSD ?= "R_SQPH_0x85be/rcw_1300"
RCWXSPI ?= "R_SQPH_0x85be/rcw_1300"
RCWEMMC ?= "R_SQPH_0x85be/rcw_1300"

Open file <project-path>/layers/meta-qoriq/recipes-bsp/secure-boot/secure-boot-qoriq/ls1028ardb.manifest,
and then set rcw related variable as below.
rcw_xspi=rcw/ls1028ardb/R_SQPH_0x85be/rcw_1300.bin
rcw_sd=rcw/ls1028ardb/R_SQPH_0x85be/rcw_1300.bin
rcw_emmc=rcw/ls1028ardb/R_SQPH_0x85be/rcw_1300.bin

# . ./setup-env -m ls1028ardb -b build_ls1028ardb
# bitbake rcw

Workaround

On LINUXEXEC-26882, it removed some NXP Yocto SDK's steps.
But, it does not fix on 6.11.1.2 Bootloader with display feature.
