L138 Experimenter's Kit Booting trouble

Elisa Pasquali

Other Parts Discussed in Thread: OMAP-L138, DA8XX, PMP, AM1808

Hello,

I've got a Logic PD Zoom OMAP-L138 Experimenter's kit that I can't boot. I've waded through the online wikis and I'm afraid I must've messed something up in the tutorials because it seems a bit confusing to me what the correct version of SDK I was supposed to download (so I downloaded them both, and tried them both, and neither work).

Basically, my problem is as follows. I set up the U-Boot variables to load from nfs with a tftp server running on Ubuntu 10.4 running on a Virtual Box. On the target board, I run tftp and the image is fetched correctly, and then...the board hangs either at the "starting kernel" stage (when I try to load the image uImage-dm37x-evm.bin that comes with the TI DVSDK) or at the "Uncompressing Linux....done, booting the kernel" stage when I tried to load the uImage that comes with the OMAP-L138 SDK). Is this a problem with my configuration, or am I loading up the wrong images, or what do you think?

These are my U-Boot environment variables:

baudrate=115200
ethaddr=00:08:ee:06:07:70
rootpath=/home/elisa/targetfs
nfshost=139.79.100.178
bootdelay=4
autoload=no
netmask=255.255.255.0

stdin=serial
stdout=serial
stderr=serial
ver=U-Boot 2009.11 (Jan 13 2011 - 01:05:37)

And these are the errors I seem to get:

Nevermind. Solved it. I used the uImage that came with the SD card in the eval board as opposed to the multitude of uImages that are available on the wikis/user guides. Booted up no problem.

Oops, I spoke too soon. Turns out, boot halts again, when trying to mount the nfs root directory. Here are my new U-boot variables and the messages that pop out when booting:

So does anyone have an idea of what's going on now? My nfs server seems to be running fine on the Ubuntu VM...

Thanks,

In your first attempt, it appears that you were using a UImage from Dm37xx, is that right? I would not expect that to work.

In your second attempt you have mixed uboot environment setups. Your bootargs indicate nfs boot but your bootcmd indicates SDMMC boot. If you obtained the uImage from a Linux PSP package, the documentation provides the different uboot arguments that are needed for the boot. Could you specify where you obtained the uboot and uImage and the reason for the mixed uboot settings.

Regards,

Rahul

Hi, Rahul,

You were right. The thing is there are so many images and so many different instructions floating out there on the wikis that it is difficult to sort out which is meant to go where (and to answer where I got which, again I couldn't tell you, they were all cobbled together from doing a search on "getting started guide OMAP L138" and following the links on the wikis, etc. I have no doubt some of these documents were obsolete or outdated). As it turns out, I had the wrong uImage and when I replaced it with the one that came in the SD card from my development kit, and followed its instructions to the letter instead of trying to "upgrade" to a more recent version for the Code Sourcery tools, etc, it all installed flawlessly. I can even see my mapped nfs directory and can transfer files between my host and target by dropping things into the targetfs directory. The U-boot environment variables that finally worked for me were as follows (in case anyone else runs into similar trouble in the future):

U-Boot > printenv
baudrate=115200
ethaddr=00:08:ee:06:07:70
rootpath=/home/elisa/targetfs
nfshost=139.79.100.178
bootdelay=4
autoload=no
bootargs=console=ttyS2,115200n8 noinitrd rw mem=32M@0xc0000000 mem=64M@0xc4000000 root=/dev/nfs nfsroot=139.79.100.178:/home/elisa/targetfs,nolock ip=dhcp
bootfile=uImage-da850-omapl138-evm.bin
bootcmd=dhcp; setenv serverip 139.79.100.178; setenv bootfile uImage-da850-omapl138-evm.bin; setenv netmask; setenv dnsip; tftp; bootm
stdin=serial
stdout=serial
stderr=serial
ver=U-Boot 2009.11 (Jan 13 2011 - 01:05:37)

The reason the bootfile variable needs to be set again on the bootcmd is that because for some reason on my system when I run dhcp it also likes to change the bootfile name to pxelinux.0 for some reason. Weird. Anyway, seems to work now.

Thanks Rahul for the hints!

Hi,

I am also struck at the same point “Uncompressing Linux... done, booting the kernel.” Using AM1808 @375MHZ with 128MB mDDR.

Running my uImage & rootfs from SD-Card, Find my bootargs:-

----------------------------------------------------------------------------

U-Boot > printenv

baudrate=115200

bootargs=init=/init console=ttyS2,115200n8 ip=off rw root=/dev/mmcblk0p2 rootwait nolock mem=128M androidboot.console=ttyS2

bootcmd=if mmc rescan 0; then if fatload mmc 0 0xc0600000 boot.scr; then source 0xc0600000; else fatload mmc 0 0xc0700000 uImage; bootm c0700000; fi; else sf probe 0; sf read 0xc0700000 0x80000 0x220000; bootm 0xc0700000; fi

bootdelay=3

bootfile=uImage

ethact=DaVinci-EMAC

hwconfig=dsp:wake=yes

stderr=serial

stdin=serial

stdout=serial

ver=U-Boot 2012.04.01 (Jan 22 2013 - 17:38:47)

Environment size: 546/65532 bytes

----------------------------------------------------------------------------

Please suggest me where I can enable(either in UBL or U-boot) and work my board with OS.

Thanks,

Francis
