[Buildroot] imx8 common script problem

[Buildroot] imx8 common script problem

[Michael Nazzareno Trimarchi]

HI all

I found that in order to generate a correct flash.bin image, the
script at the moment are broken at least for imx8mn. It works only
with this change

  ${HOST_DIR}/bin/mkimage_imx8 -fit -loader
${BINARIES_DIR}/u-boot-spl-ddr.bin 0x7E1000 -second_loader ${BIN
ARIES_DIR}/u-boot.itb 0x40200000 0x60000 -out ${BINARIES_DIR}/imx8-boot-sd.bin
        elif grep -Eq "^BR2_PACKAGE_FREESCALE_IMX_PLATFORM_IMX8MN=y$"
${BR2_CONFIG}; then
-               cat ${BINARIES_DIR}/u-boot-spl.bin
${BINARIES_DIR}/ddr_fw.bin > ${BINARIES_DIR}/u-boot-spl-ddr.bin
+               dd if=${BINARIES_DIR}/u-boot-spl.bin
of=${BINARIES_DIR}/u-boot-spl-pad.bin bs=4 conv=sync
+               cat ${BINARIES_DIR}/u-boot-spl-pad.bin
${BINARIES_DIR}/ddr_fw.bin > ${BINARIES_DIR}/u-boot-spl-ddr.bin
                BL31=${BINARIES_DIR}/bl31.bin
BL33=${BINARIES_DIR}/u-boot-nodtb.bin ATF_LOAD_ADDR=0x00960000
${HOST_DIR}/bin/mkimage_fit_atf.sh ${UBOOT_DTB} >
${BINARIES_DIR}/u-boot.its
                ${HOST_DIR}/bin/mkimage -E -p 0x3000 -f
${BINARIES_DIR}/u-boot.its ${BINARIES_DIR}/u-boot.itb
-               rm -f ${BINARIES_DIR}/u-boot.its
+               #rm -f ${BINARIES_DIR}/u-boot.its


The padding seems correct even in the origina soc.mk of imx tools. Can
anyone comment?

Michael

I think the correct person to ask is Stephan that added support for:
board/freescale/imx8mnevk/
configs/freescale_imx8mnevk_defconfig
and he maintains him as you can find in DEVELOPERS file.

Michael, can you please send a patch --in-reply= to this e-mail with 
these changes putting in Cc all people I've listed here? So it's easier 
to review it. Especially for Stephan or who else owns a board with this SoC.

Unfortunately I don't have such hardware :-/
