Hi,

What Linux SDK version are you using ?

MCSDK or Linux LCDK's SDK ?

Could you please share your bootup logs.

I'm using Linux LCDK's SDK

Hi Sangly,

I'm also facing the same problem on Linux LCDK's SDK (kernel image) and I'm not getting any issues in MCSDK release SDK.

I will try to figure out that where is the problem.

Mean while please check in MCSDK.

How to get the MCSDK for OMAPl138 ? 

Hi,

The below link is have latest MCSDK release for OMAPL138 (LCDK,SDI &EVM) with linux kernel ver3.3.

http://software-dl.ti.com/sdoemb/sdoemb_public_sw/mcsdk/latest1/index_FDS.html

Hi, 

Got the sources.

copied the u-boot into SD card from mcsdk_1_01_00_02/images/u-boot-omapl138-lcdk.bin

by following command

desktop:/mediaAM1808/preparation$ sudo ./uflash -d /dev/sdb -b u-boot-omapl138-lcdk.bin -p OMAPL138 -vv
OMAPL138
U-Boot Size 356635
First partition starts at 32130(16450560)
U-Boot Magic Number : a1aced66
U-Boot Entry Point : c1080000
U-Boot Number of Blocks : 000002b9
U-Boot Starting Block : 00000075
Load U-Boot Address : c1080000

copied the uImage into SD card (/media/boot)from mcsdk_1_01_00_02/images/uImage-omapl138-lcdk.bin and copied the filesystem into /media/rootfs

But its not getting boot i'm not getting any log.

Whats wrong in this what is the procedure to boot the board?

Hi,

You don't want to change the u-boot but just change the kernel (3.3) alone.

I tried but not booting successfully.

Its restarting

I followed the link http://processors.wiki.ti.com/index.php/OMAP-L138_Preparing_SD_Card_for_Boot

Please let me know what are images to be in SD card from mcsdk_1_01_00_02 and tell me the procedure ?

Hi,

You can follow the same procedure which you have done LCDK's SDK.

Procedure is the same for MCSDK and LCDK's SDK.

Ya i'm following same procedure but i cant't getting uboot log.

Which u-boot image i need to flash in SD card from mcsdk_1_01_00_02 ?

Hi,

Ya i'm following same procedure but i cant't getting uboot log.

Which u-boot image i need to flash in SD card from mcsdk_1_01_00_02 ?

We don't have separate procedure for MCSDK & LCDK's SDK releases.

How did you perform to boot the board with old u-boot or LCDK's SDK ?

You can use everything as it is from LCDK's SDK except kernel.

You may have bootable SD card for LCDK's SDK and replace kernel image only.

I flashed the LCDK image into SD card long back(6 months). 

Now i formatted the SD card for new kernel, i forgot the procedure to flash the SD card so followed that link. 

I took the mcsdk/images/uboot and signed by AIS tool then used the uflash tool to flash the uboot image into sd card but its not booting. 

Can you share the AIS signed and working uboot and uImage (Linux 3.3) for LCDK to flash the SD card ?

And please tell the procedure to to flash those image into SD card.

Thanks 

Hi Sangly,

For this SD creation, I have posted multiple replies in e2e forums, you can search in our forums and try to boot as like initial.

After that try to change the kernel (3.3) alone.
