hi all ......

              Here i am using   TI_Android_FroYo_DevKit-V2.2 android stack for DM3730 board i m able to flash everything from SD card to NAND FLASH mode..But while running  the board its showing  the following error..

## Booting kernel from Legacy Image at 82000000 ...
   Image Name:   Execute uImage.bin
   Image Type:   ARM Linux Script (uncompressed)
   Data Size:    357 Bytes = 357 Bytes
   Load Address: 00000000
   Entry Point:  00000000
   Contents:
      Image 0: 349 Bytes = 349 Bytes
   Verifying Checksum ... OK
Wrong Image Type for bootm command
ERROR: can't get kernel image!
                                   

 

                                    I am unable to find where i am doing wrong.Please suggest some ideas to solve the issue.

 
Thanks,

    You appear to have flashed an incorrect image. Please try with the 'AM37X EVM UBIFS NAND Flash Images' prebuilt package available at

    http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/02_02_00/index_FDS.html

    The prebuilt-package for DM37x does not support NAND boot.

    You need to prepare the sdcard - just like in case of sd-boot. The mk-mmc utility in the package will copy the bootloader, kernel filesystem etc into the sdcard along with a special script which will write these on the Flash.

    Once you have prepared the sdcard, setup your board for sd-boot. Insert the card and power-up. You should see messages in the console saying "flashing xx to NAND". Once this is succesfully completed, poweroff and set the DIP switches for NAND-boot.

    You still need the sd-card as android uses it for data partition.

     

    EDIT: It appears that the instructions at the download page are not clear to you. We will try to make improvements in the setup instructions.
