Unable to read "uImage" from SD card !

Hi lee,

Refer to the following http://processors.wiki.ti.com/index.php/TI81XX_PSP_UBOOT_User_Guide#U-Boot_Environment_Variables

you can either set the boot cmd as below

setenv bootcmd 'mmc init;fatload mmc 1 0x81000000 uImage;bootm 0x81000000'

or add the following to boot.scr.

fatload mmc 1  0x81000000 uImage

bootm 0x81000000

if it's not solved then provide the contents of boot.scr as well.

Regards,

RK

Hi:
I've took your suggestion,and reset my bootcmd,but the uImage still can't be read!
here are my new console logs:

** Unable to read "uImage" from mmc 1:1 **
Wrong Image Format for bootm command

TI8168_EVM#

Well,my boot.scr file in SD card can't be opened, but I could read from
boot.cmd file as following:

setenv bootargs 'console=ttyO2,115200n8 rootwait root=/dev/mmcblk0p2 rw mem=256M earlyprink vram=50M ti816xfb.vram=0:16M,1:16M,2:6M ip=off noinitrd'
fatload mmc 1 0x80009000 uImage
bootm 0x80009000

Also,I've changed bootargs into 'mmc init;fatload mmc 1 0x0x80009000 uImage;bootm 0x80009000', it didn't work either!

Could you still help me with this?

Thank you very much!

Best regards!

fatload mmc 1 0x0x80009000 uImage

The above commands are for old PSP versions (PSP_04.00.00.12 and older release). For new PSP versions use:

$mmc rescan 0

$fatload mmc 0 <addr> <file>

Regards,
Pavel

As Pavel mentioned ,

change your mmc partition id in the command

bootcmd=mmc init;fatload mmc 0 0x81000000 uImage;bootm 0x81000000

But it till cann't read the uImage!

You can also try the below (after you enter in the u-boot prompt), do the below instead just typing #boot

TI8168_EVM#mmc rescan 0
raise: Signal # 8 caught
TI8168_EVM#fatload mmc 0 0x80009000 uImage

If the above does not help, the best thing you can do here is to create MMC/SD card with the ti-ezsdk_dm816x-evm_5_05_02_00/bin/mksdboot.sh script. This script will format your MMC/SD card and make all the correct settings (boot arguments, loadbootscript, bootcmd) and will place u-boot and uImage (pre-built) in the card.

So, run this script on your MMC/SD card, and try to boot with it. On a success, you can build your own u-boot and uImage and replace them in the MMC/SD card.
