Problem in booting latest OMAP35x Linux PSP 02.01.01.08 2.6.29-rc3 kernel uImage on OMAP35x EVM

Other Parts Discussed in Thread: OMAP3530

Dear experts,

I am getting the following errors while booting the uImage which is build using the latest OMAP35x Linux PSP 02.01.01.08 2.6.29-rc3 kernel source.

I had flashed the u-boot, x-loader and ramdisk images which has taken from this release version.

I had given the following boot args in u-boot prompt as:

setenv bootargs mem=128M console=ttyS0,115200n8 noinitrd ip=<board_IP_address> rw root=/dev/nfs nfsroot=$(nfshost):$(rootpath),nolock,rsize=4096,wsize=4096,proto=tc

The filesys is taken from this same PSP package.

Can anybody suggests me to solve this error

    Haven't see this error myself.

    1) Do you see any NAND related errors when the u-boot comes up?

    2) Can you also try to compile out NAND driver (just for test purpose) and see if it helps?

    I am not very sure about the errors in initscript. Just wanted to confirm if you extracted the filesystem tarball with root permissions (as "root' or via sudo).

    Best regards,
    Sanjeev

    Hi,

    Thanks for your reply to my query

    I always extracting filesystem tarball with root permissions only.

    Previously, I had used images/fs/nfs.tar.gz which is in PSP-SDK-02.01.01.08 directory.

    Now, I had changed this to targetfs/nfs.tar.gz from dvsdk_3_00_00_36 directory. And done memory adjustments in initenv.txt file as per the guidelines provided in dvsdk getting started guide.

    Also removed "proto=tcp" from bootargs command.

    Now, it is booting successfully and I am getting the following boot messages:

    But still, errors are there related to buffer I/O "Buffer I/O error on device mtdblock0, logical block 0"

    Could you please give me suggestions to rectify this problem if you have faced this ?

    And also why it is booting after removing proto=tcp command?

    Not sure. Did anything changed on your NFS server? May be change to the NFS configuration OR change in the params (/etc/exports).

    Did you try compiling out the NAND driver from kernel configuration?

    I haven't personally worked on the DVSDK myself. But will try to get some details.

    Thanks for your reply.

    As per your suggestion, I will try to compile the NAND driver from kernel configuration and see its result.

    Thanks,

    Hello Hemanth,

     

    Did you resolve this problem?

     

    I am also seeing these issues

    "<3>uncorrectable error : uncorrectable error : <3>end_request: I/O error, dev mt
    dblock0, sector 0"

    with the dvsdk 3.00.01.42.

    Hello Simon,

    I had modified the intenv-micron.txt file (if your board is of type samsung, change intenv-samsung.txt file)

    Refer omap3530_dvsdk_GettingStartedGuide file to modify this.

    And I had given the following boot arguments in u-boot prompt:

    setenv bootargs console=ttyS0,115200n8 noinitrd rw ip=<ip address of your board> root=/dev/nfs nfsroot=$(nfshost):$(rootpath),nolock,proto=tcp mem=88M omapfb.rotate=1 omapfb.rotate_type=1 omap_vout.vid1_static_vrfb_alloc=y

    I had used the filesys given in targetfs directory in dvsdk_3_00_00_36 folder.

    Now, the boot starts without any errors and entered into my filesystem successfully.

    Also loaded all the modules and I am able to run dvsdk demos without any problem.

     

    Regards,

    Hemanth Kumar P

    Hello Hemanth,

     

    Thanks for your reply.  I have also made these changes to my bootargs, but  I am still seeing the mtd errors :(

    Did you also reflash xloader, uboot, kernel or the filesystem?  With the reflash-micron.txt script?

     

    I have been using the filesystem from the SDK package.  I will try the file system from the dvsdk.

    Thanks, again.

    Hello Hemanth,

     

    I needed to modify the udev intitialization to remove these errors.  The change is shown in this thread:
