Other Parts Discussed in Thread: AM3892

Hello,

ARM Booting with SD Boot mode is not working,

we are using AM3892 Device,

Following testing were done,

1)Checked all the Power domains,sequencing and Clock domain for ARM Sitara AM3892 device - working
2)Checked for POR status on Pin RSTOUT of AM3892 device - POR working.
3)SD clock  generated from AM3892 device .
4)Did ARM DDR Read/Write test with .GEL file - working.
5)Read the BOOT STATUS Register in CCS,BOOT Strap pins are configures to SD Boot Mode.
6)Printouts on Teraterm while booting ARM with SD Boot mode, 
U-Boot 2010.06 (Feb 10 2015 - 12:21:23)

DRAM: 256 MiB
MMC: OMAP SD/MMC: 0
Using default environment

Hit any key to stop autoboot: 0 
mmc_init_stream: timedout waiting for cc2!
mmc_send_cmd : timeout: No status update
Card did not respond to voltage select!
** Can't read from device 0 **

** Unable to use mmc 0:1 for fatload **
## Starting application at 0x80800000 ...

Thanks,

    Hello,

    What you mean by AM3892 Device is it custom board or EVM?

    What are the bootargs?

    How you are creating the SD card?

    If you are using the script :

    • 1st partition is formatted as FAT32 containing MLO, u-boot.bin, uImage files
    • 2nd partition is formatted as ext3 where the filesystem is extracted in root.

    if you not check the above points.

    You could check the uboot user guide about  SD card booting.

    Hello Margarita,

    Thanks for the reply,

    Actually its custom board with AM3892 device,

    I did'nt get what is Bootargs ?

    Can you please let me know the link for  uboot user guide for SD card booting.

    Iam able to Read/write DDR through .Gel file and also able to read BOOTSTATUS Register(which is set to SD boot mode) with CCS.

    Thanks,

    Hello,


    Bootargs=boot arguments.

    Here is the link for the user guide:

    Please search for the SD boot.

    Could you check the SD card holder as well.

    Best Regards,

    Margarita
