Re: Problems while booting a linux system on fast models based CortexA15

[Mai Daftedar <mai.daftedar@xxxxxxxxx>]

I still have no luck in bringing up the host on fast models.

There is something I'm definitely missing out :

Theses are my suggested potential errors:

When I execute the following command as mentioned in the pdf
mkfs.ext3 ./disk.img

The following occurs..Is this okay?

--------------------------------------------------------------------------------------
./disk.img is not a block special device.
Proceed anyway? (y,n) y
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
32768 inodes, 131072 blocks
6553 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=134217728
4 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks:
    32768, 98304

Writing inode tables: done                           
Creating journal (4096 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 29 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.

I use the params file as follows:
motherboard.smsc_91c111.enabled=1
motherboard.hostbridge.userNetworking=1
cluster.cpu0.semihosting-cmd_line="--kernel uImage --dtb host-a15.dtb -- earlyprintk console=ttyAMA0 mem=2048M root=/dev/mmcblk0 rw ip=dhcp"
motherboard.mmc.p_mmc_file="disk.img"

I still get the errors:

Thanks Christopher for your reply. Please excuse my in-experience in this

These are literally the semihosting commands I use (I define them in a params file):

motherboard.smsc_91c111.enabled=1
motherboard.hostbridge.userNetworking=1
cluster.cpu0.semihosting-cmd_line=--kernel uImage --dtb host-a15.dtb -- earlyprintk console=ttyAMA0 mem=2048M root=/dev/nfs nfsroot=192.168.0.45:/srv/nfsroot/ rw ip=dhcp
motherboard.pl011_uart0.out_file=/home/mai/ARM/somefile
motherboard.pl011_uart0.unbuffered_output=1

and I defined the following in the /etc/exports file

/srv/nfsroot 192.168.0.0/255.255.0.0(rw,sync,no_root_squash,no_subtree_check,insecure)

To run the model shell i use the following:

model_shell cadi_system_Linux-Release-GCC-4.6.so -f params  /home/mai/ARM/boot-wrapper/linux-system-semi.axf

I read that there is another way to run this using an mmc image. Can you please advice.

Hello,

I suggest for you to check out chapters 6.1, about bridge networking, and if you still have troubles then 6.4 MMC booting (image file should be less than 2 GB) from the KVM-on-ARM guide.

Regards.
