C6A816x-evm kernel boot fails on NAND but works on SD

hutchman
Expert 1100 points
Other Parts Discussed in Thread: PMP

Hi,

I have bitbaked a new arago-console image and generated a new kernel and rootfilesystem.  The kernel works when booted from the SD card (rootfs is mounted via NFS) but when I try to boot the same kernel via NAND it fails.

The version of the kernel that I bitbaked is called linux-omap3-2.6.36+2.6.37-rc3-psp04.00.00.09

I noticed some small changes of the output when booting from SD vs NAND.  Does something need to be done different to the kernel to get it to boot out of NAND?

Here is the dmesg output of booting out of the SD (which works):

... and the above line is where the kernel booting dies.

Anyone seen this before of have a clue what the issue is?

I'm tempted to do a bitbake update to see if maybe something was already fixed in upstream git tree.

Brian

    Instead of ttyS2 you should be using ttyO2 (thats an O as in OMAP). This is mentioned in the ReadMe first section of the User Guide.

    The NFS filesystem mounted in SD boot mode has the "/etc/inittab" file updated to launch a console on both ttyS2 and ttyO2 because of which the issue gets masked out. However the filesystem that is on NAND does not have both the entries and hence you see junk characters on the console.

    Vaibhav, which User Guide were you talking about because I must have missed that?  I have the TI816x-PSP 04.00.00 EA3 UserGuide and it says to use ttyS2.  I made the change you mentioned to ttyO2 and it did get further but then dies in another spot! :(

    Vaibhav,

    Just to clarify, the uImage & root filesystem I am using in NAND and SD are exactly the same!  I did mkfs.jffs2 on the directory I'm using for NFS mounting to create the image I then flashed to NAND.

    Regards,

    Brian

    Brian,

    I should have mentioned the doc that i was referring to: http://processors.wiki.ti.com/index.php/DM816x_C6A816x_AM389x_PSP_04.00.00.10_User_Guide.

    The NAND boot issue seems to be due to mtdblock mismatch. Since the defconfig now has both SPI and NAND enabled, mtdblock7 should be used. More info here: http://processors.wiki.ti.com/index.php/DM816x_C6A816x_AM389x_PSP_04.00.00.10_U-Boot#Environment_Settings_for_JFFS2_Filesystem

    Regards,

    Vaibhav

    Hi Vaibhav,

     

    I saw that document and tried mtdblk7 but that didn't fix it for me.  I'm currently using PSP 04.00.00.09 from the Arago git and am wondering when I can use 04.00.00.10 as I've been following the commit messages and think that maybe that is the version I should be using.

     

    Regards,

     

    Brian

    Brian,

    Is the error message still the same? If yes, can you please double check the step for creating the jffs2 filesystem with the doc. If not, can you provide the error log.

    Regards,

    Vaibhav
