Linux/TMDSSK3358: AM335x SD Boot Problem

Part Number: TMDSSK3358
Other Parts Discussed in Thread: AM3358

Tool/software: Linux

I am using AM335x Start-Kit, TMDSSK3358 and I am trying to use  PROCESSOR-SDK-AM335X  but every time SD boot failed with following message 

U-Boot SPL 2016.05 (Feb 20 2017 - 16:27:15)
Trying to boot from MMC1
** First descriptor is NOT a primary desc on 0:1 **
** Partition 1 not valid on device 0 **
spl_register_fat_device: fat register err - -1
** Partition 1 not valid on device 0 **
spl_register_fat_device: fat register err - -1
spl_load_image_fat: error reading image u-boot.img, err - -1
spl: no partition table found
spl: no partition table found
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

so I did test about MLO,  changed Android MLO to Linux MLO but it was same  

but SD Boot on the Android was so different  if I used Linux MLO or Android MLO on the Android  ,  SD boot was working properly 

so I think  this problem is partition problem or other problem.

I used TI-Image and Win32DiskImager Program  

Thanks for reading my message

    Hi,

    Android is not supported by TI. There isn't any "Android MLO" present in the Processor SDK - Linux. Have you tried with the prebuilt card image? The Starter Kit should boot from it with no issues.

    Hi Biser,

    MLO for Android included ICS 4.0.3 DevKit 3.0.1 on SD Card is working properly now, that is no problem but

    I want to do test with prebuilt image, am335x-evm-linux-03.02.00.05.img.zip in software-dl.ti.com/.../index_FDS.html or what I made , exactly by using /bin/create-sdcard.sh.

    this images,(Linux-SDK) was not working properly.
    it was not working with this images on the AM335x Start-Kit, TMDSSK3358 so now I am checking SD-PIN CD( Card detection ) in MLO

    Thanks and Regards

    Hi,

    I tested my AM3358 Starter Kit with the latest u-boot 2016.05 (SDK 03.02.00.05) and the device boots normally.

    I am not sure what is wrong on your side. Can you provide the steps you took to make your sd card & boot the boar?

    Best Regards,
    Yordan
