E rror4:
mmci-omap mmci-omap.0:MMC CRC DATA
mmcblk0: error -84 transferring data
Solution:
repartition the SD card into two partitiones:FAT32 and ext3.
Error:
We could
see the string "Android" displayed on the LCD. The full android build does
not seem to bring up the phone active home screen.
Solution:
There is something wrong with the filesystem,maybe two reasones made this error,one is when you make the android ,some mistakes occurred ,you can “ make clean ” under the android root folders before syncing again ; another is you could try to change the priority of system folders by “ chmod – R 777 system ” .
More Important:
Do remember to make the name of kernel image in the SD card be “ uImage ” .
#setenv bootfile=uImage
Do make the ” init=./init “ in the setting of bootargs, because the init is the executable file.
Do not use the command “ mkimage – A ..-T ..-O …” to generate the uImage,the best way to make the uImage is to add the path of u-boot ’ s tools into the PATH.
E xp: $sudo vim /etc/bash.bashrc
A nd then change the PATH to
PATH=/usr/local/arm/arm-2008q3/bin:/home/wenjuan/android/bootloader/u-boot/tools/: ” {$PATH} ”
