AM335xsk starter kit not boot from the SD card

Santosh Bongane1

Hi,

I am trying to boot the AM335xsk starter kit using SD card but , after reseting the starter kit it shows following text on serial console.

U-Boot SPL 2011.09-00000-g6035fc2 (Nov 16 2012 - 15:05:21)
Texas Instruments Revision detection unimplemented
No daughter card present
OMAP SD/MMC: 0
reading u-boot.img
spl: error reading image u-boot.img in FAT mode, err - -1
spl: Reading image in RAW mode
mkimage signature not found - ih_magic = 0
Assuming u-boot.bin ..

i think there is Boot file problem,

or else pls. help to come out this scenario.

Thanks in Advance

Hi,

Which version of the AM335x SDK are you using?

Please try to reformat your sd card using the provided create-sdcard.sh script located inside the /bin folder in the SDK, or try with a new SD card.

Best regards,
Miroslav

Can you verify the downloaded files against the md5 sums provided on the download page?

Can you post the output during the creation of the SD card? I just tried reformatting an SD card using the pre-built images from the link you posted and they seem to work fine.

Best regards,
Miroslav

checksum provided with page matched with file.

i use to following command to prepare sd card

Command: sudo ./mkmmc-android.sh <device>

Example: sudo ./mkmmc-android.sh /dev/sdc
Details: In this case, the script will assume default locations for BootImages,

Root Filesystem, Media_Clips and START_HERE. This command is equivalent to the following


sudo ./mkmmc-android.sh /dev/sdb Boot_Images/MLO Boot_Images/u-boot.img Boot_Images/uImage Boot_Images/uEnv.txt Filesystem/rootfs.tar.bz2 Media_Clips START_HERE


If you are in a particular Board Specific Directory, extracted from DevKit Release, then you can prepare the sd card by executing


sudo ./mkmmc-android.sh <device>, to prepare sd card.

... The SD card device name is sdb.

SD card partition contains all Boot , rootfs and images files

Santosh, I meant the output from the script after you run it. Were there any erroneous messages?

Best regards,

Can you just copy-paste the output from the mkmmc-android.sh script? It's only around 15 lines, so no need to put it in a file and attach it - just paste it. I want to see if everything went OK with the SD card formatting.

Best regards,
Miroslav

Hi Santosh,

The script name is mkmmc-android.sh, not mkmmc-android.

Best regards,
Miroslav
