Android Gingerbread Demo image can't work

[zhoujie]

Hi

    I used the QSB of "i.MX53-QSB-Android-Gingerbread-Release4.0" ,download the image by the "flash_prebuild_android.sh " in the folder "scripts".

   Boot environment variables are set as follows(referenced the document "Adeneo i.MX53 Quick Start Board BSP for Android Gingerbread User Guide and Release Notes v4.0"):

  # setenv ethaddr 00:04:9f:01:b4:08
  # setenv fec_addr ${ethaddr}
  # setenv bootcmd ‘run bootcmd_SD1 bootcmd_SD2’
  # setenv bootcmd_SD1 'run bootargs_base bootargs_android'
  # setenv bootcmd_SD2 'mmc read 1 ${loadaddr} 0x800 0x2000;mmc read 1
    ${rd_loadaddr} 0x3000 0x300;bootm ${loadaddr} ${rd_loadaddr}'
  # setenv bootargs_base 'setenv bootargs console=ttymxc0,115200'
  # setenv vga ‘setenv bootargs ${bootargs} init=/init
    androidboot.console=ttymxc0 di1_primary tve ip=dhcp’
  #setenv lcd ‘setenv bootargs ${bootargs} init=/init
    androidboot.console=ttymxc0 di0_primary calibration ip=dhcp'
  # setenv bootargs_android ${lcd}
  # setenv loadaddr 0x70800000
  # setenv rd_loadaddr 0x70D00000
  # saveenv

  But,the board can't run,and the log said:

  What's wrong?please your help.

  Sorry for my English.

Thank!

setenv is done prior to loading the OS so at your prompt you type type the command above. There is a document for the U-Boot called uboot_mxc.fm in your docs directory

Hi, as I'm new, where should I change it (under which path should I find the file where to change this parameter)?

I've tried looking under src/kernel_imx , but I cannot find it.

Thanks

You need to change the bootcmd_SD2 environment variable as follows:

setenv bootcmd_SD2 'mmc read 0 ${loadaddr} 0x800 0x2000;mmc read 0 ${rd_loadaddr} 0x3000 0x300;bootm ${loadaddr} ${rd_loadaddr}'

This tells U-Boot to load the OS from the micro-SD card slot instead of the full-size SD card slot.
