targetfs not found by DM8168

Hi Sanjay Sanju,

     Could you provide a little more of background on your issue? I think I didn't get your question. Have you tried with the Ridgerun EVAL SDK?

Hello David, 

           I am not using the ridgerun EVAL SDK, instead I am using the EZSDK provided by TI. I have tried using the version ti-dm816x_evm-5_05_01_04 and ti-dm816x_evm-5_05_02_00.

I am following the procedure step by step while trying to see the targetfs from the target [ DM8168 ], however I am not successful.

Kindly advice.

Hi Sanjay,

     I would recommend you to try to configure the EZSDK to boot from an SD card, you can find instructions about how to do it here:

http://processors.wiki.ti.com/index.php/EZSDK_Using_data_on_SD_and_filesystem_on_NAND

Also there are some tutorials on line about using the EZSDK: http://www.fedevel.com/welldoneblog/2011/10/starting-with-ti-exsdk-c6a816x-video-tutorial/

In general, you can find the filesystem of the EZSDK on /home/$USER/ti-ezsdk_dm816x-evm_5_05_02_00/filesystem/ezsdk-dm816x-evm-rootfs.tar.gz

Also, the Ridgerun SDK is already integrated with the EZSDK,  the eval should work if you following step by step this guide: https://developer.ridgerun.com/wiki/index.php/Getting_Started_Guide_for_DM8168_EVM

Also, I don't know why your EZSDK is not creating your filesystem directory, but you can check in your uboot environment where is the board looking for the filesystem, from uboot, stop the countdown and type printenv, it should show you bootargs, something like:

bootargs=console=ttyO2,115200n8  notifyk.vpssm3_sva=0xBF900000 root=/dev/mmcblk0p2 rootdelay=2 rootfstype=ext4  mem=364M@0x80000000 mem=320M@0x9FC00000 vmalloc=512M vram=81M 

Hello David,

        When I stop the countdown from u-boot and type printenv, The following output is seen.

bootcmd=if mmc rescan 0; then if run loadbootscript; then run bootscript; else echo In case ENV on MMC/SD is required; echo P lease put a valid script named boot.scr on the card; echo Refer to the User Guide on how to generate the image; fi; else echo

Please set bootargs and bootcmd before booting the kernel; echo If that has already been done please ignore this message; fi

These lines were missing on the previous post!

I do not see anything similar to what you mentioned in your post in the response what I get on the console. What should be inferred from this? Kindly advice.

Hi Sanjay,

         You don't see those lines because in your case, uboot will run the instructions present in the bootcmd variable which at some point runs 

fatload mmc 0 ${script_addr} boot.scr

this part will load the definitions from the boot.scr file present in your SD card (http://processors.wiki.ti.com/index.php/DM816x_AM389x_PSP_U-Boot#ENV_on_SD_card_using_a_script) which should contain something like:

bootargs=console=ttyO2,115200n8  notifyk.vpssm3_sva=0xBF900000 root=/dev/mmcblk0p2 rootdelay=2 rootfstype=ext4  mem=364M@0x80000000 mem=320M@0x9FC00000 vmalloc=512M vram=81M
