Error boot Android 5.0 on custom board with 2G DRAM

Hi all

I built and ran Android 5.0 on imx6q-sabre SD of freescale successfully. But with my custom board uses 2G DRAM, i modified source to build new u-boot:

First, modified the content of file "~/myandroid/bootable/bootloader/uboot-imx/boards.cfg": DDR_MB=1024 -> DDR_MB=2048:

"mx6qsabresdandroid mx6sabresd:IMX_CONFIG=board/freescale/imx/ddr/mx6q_4x_mt41j128.cfg,MX6Q,DEFAULT_FDT_FILE="imx6q-sabresd.dtb",DDR_MB=2048,SYS_USE_SPINOR,ANDROID_SUPPORT ..."

Then, follow user guide document:

$ cd ~/myandroid/bootable/bootloader/uboot-imx

$ export ARCH=arm

$ export CROSS_COMPILE=~/myandroid/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-

$ make distclean

For i.MX 6Quad SABRE-SD:

$ make mx6qsabresdandroid_config

Configuring for mx6qsabresdandroid - Board: mx6sabresd, Options: IMX_CONFIG=board/freescale/imx/ddr/mx6q_4x_mt41j128.cfg,MX6Q,DEFAULT_FDT_FILE="imx6q-sabresd.dtb",DDR_MB=2048,SYS_USE_SPINOR,ANDROID_SUPPORT

$ make

After that, i download u-boot.imx to SD and run on custom board, but the console only shows:

U-Boot 2014.04-08648-g9d7bf9b (Oct 09 2015 - 11:08:36)

CPU: Freescale i.MX6Q rev1.5 at 792 MHz

CPU: Temperature 33 C, calibration data: 0x56a4df69

Reset cause: POR

Board: MX6-SabreSD

I2C: ready

DRAM:

That's all.

It took me a long time. Please help me solve this error. Thanks

HI Dang

*.cfg file should be also updated with calibration settings obtained

from ddr test

i.MX6/7 DDR Stress Test Tool V2.20

Just for reference attached 2GB init script for arm2 board.

Best regards

igor
