以下所有的操作基于``
kernel下面生成的boot.img是RKIMG(RKIMG is a format customized by Rockchip from Android boot image)的镜像,因为u-boot里面用的命令是android_boot(之前不知道这个东西是用安卓启动的方式启动linux内核的,误解成是bootrkp)
然后FIT镜像是uboot.itb,在uboot目录下的fit,可以用dumpimage -l uboot.itb查看.
TSPI的原厂固件boot.img,recovery.img也是一个FIT镜像
所以镜像分两种,一个是uboot FIT一个是android镜像
分区信息可以在执行完./make.sh orangepi-3b-rk3566后看见fit/u-boot.its

如何pack idblock(idbloader)?
在u-boot下面进行
./make.sh --idblockshell源码:
function pack_idblock()
{
INI=${INI_LOADER}
if [ ! -f ${INI} ]; then
echo "ERROR: No ${INI}"
exit 1
fi
# chip
COMMON_H=`grep "_common.h:" include/autoconf.mk.dep | awk -F "/" '{ printf $3 }'`
PLAT=${COMMON_H%_*}
# file
SPL_BIN=${RKBIN}/`filt_val "FlashBoot" ${INI}`
TPL_BIN=${RKBIN}/`filt_val "FlashData" ${INI}`
if [ ! -z "${ARG_SPL_BIN}" ]; then
SPL_BIN=${ARG_SPL_BIN}
fi
if [ ! -z "${ARG_TPL_BIN}" ]; then
TPL_BIN=${ARG_TPL_BIN}
fi
# pack
rm idblock.bin -f
./tools/mkimage -n ${PLAT} -T rksd -d ${TPL_BIN}:${SPL_BIN} idblock.bin
echo "Input:"
echo " ${INI}"
echo " ${TPL_BIN}"
echo " ${SPL_BIN}"
echo
echo "Pack ${PLAT} idblock.bin okay!"
echo
}运行后终端提示:
(py2) ➜ u-boot-orangepi git:(v2017.09-rk3588) ./make.sh --idblock

Pack rk3568 idblock.bin okay!在运行./make.sh xxx时候INI_LOADER如何被选中?
看源码make.sh, 是从当前目录下的.config中寻找CONFIG_LOADER_INI
function select_ini_file()
{
# default
INI_LOADER=${RKBIN}/RKBOOT/${RKCHIP_LOADER}MINIALL.ini
if [ "${ARM64_TRUSTZONE}" == "y" ]; then
INI_TRUST=${RKBIN}/RKTRUST/${RKCHIP_TRUST}TRUST.ini
else
INI_TRUST=${RKBIN}/RKTRUST/${RKCHIP_TRUST}TOS.ini
fi
# defconfig
NAME=`filt_val "CONFIG_LOADER_INI" .config`
if [ ! -z "${NAME}" ]; then
INI_LOADER=${RKBIN}/RKBOOT/${NAME}
fi
NAME=`filt_val "CONFIG_TRUST_INI" .config`
if [ ! -z "${NAME}" ]; then
INI_TRUST=${RKBIN}/RKTRUST/${NAME}
fi
# args
if [ ! -z "${ARG_INI_TRUST}" ]; then
INI_TRUST=${ARG_INI_TRUST}
fi
if [ ! -z "${ARG_INI_LOADER}" ]; then
INI_LOADER=${ARG_INI_LOADER}
fi
}小勘误
rockchip wiki上面是这样从bin 制作img的(img烧录到sd卡中)
tools/mkimage -n rkxxxx -T rksd -d rkxx_ddr_vx.xx.bin idbloader.img
cat rkxx_miniloader_vx.xx.bin >> idbloader.img但是这样会有问题(提示文件过大)
然后用make.sh里面的方法:
./tools/mkimage -n ${PLAT} -T rksd -d ${TPL_BIN}:${SPL_BIN} idblock.bin
