hello,
i want to embed u-boot-2015.04 for imx6q, our board runs ok with L3.0.35_4.1.0_130816 u-boot-2009.08。
what should i do?
The following is right?
i add "#define CONFIG_SPL" in include/configs/mx6sabresd.h,then
make mx6qsabresd_defconfig
or
make mx6sabresd_spl_defconfig
and how to download?
i modified E:\Mfgtools-Rel-4.1.0_130816_MX6Q_UPDATER_pinao\Profiles\MX6Q Linux Update\OS Firmware\ucl2.xml:
<CMD state="Updater" type="push" body="$ echo 0 > /sys/block/mmcblk0boot0/force_ro">access boot partition 1</CMD>
<CMD state="Updater" type="push" body="send" file="files/tasco/u-boot-spl.bin">Sending U-Boot-Spl</CMD>
<CMD state="Updater" type="push" body="$ dd if=$FILE of=/dev/mmcblk0 bs=512 seek=2 skip=2">write U-Boot-Spl to sd card</CMD>
<CMD state="Updater" type="push" body="send" file="files/tasco/u-boot.bin">Sending U-Boot</CMD>
<CMD state="Updater" type="push" body="$ dd if=$FILE of=/dev/mmcblk0 bs=512 seek=50 ">write U-Boot to sd card</CMD>
it's doesn't work, can you help me?
Hi Chen
first please run ddr test for new board (or reuse values
from working dcd header for u-boot-2009.08)
and enter new values to *.cfg file in uboot/../board/freescale/mx6sabresd.
Then rebuild uboot, I think it is not necessary to define CONFIG_SPL.
For programming Use MFG Tools for approprieate BSP, for example
Programmers (Flash, etc.) (9)
IMX6_L3.14.52_MFG_TOOL (REV L3.14.52_1.1.0)
Best regards
igor

uboot-imx.git - Freescale i.MX u-boot Tree Dose this u-boot version for imx6q need spl or not?
spl usage is optional.
without spl u-boot-2015.04 can copy itself to sdram, our board like public board, because of we do nothing with u-boot-2009.08, u-boot-2009.08 do works ok.
so what should i do for u-boot-2015.04
ps:
u-boot-2009.08:
make mx6q_sabresd_config
u-boot-2015.04:
make mx6sabresd_spl_defconfig
right ?
tks.
