Tool/software: Linux

Hello support,

I am using : Ubuntu 14.04; clean install of SDK 5.0

my connections are : VMWare Ubuntu --> AP/router --> EVM.

I've tried static and dhcp ip addresses

Question: why is ipaddr needed if i'm setup for DHCP?
Question: where does u-boot get the names of zImage, DTB, etc?
Question: what am i missing?

I am using the following TFT and NFS setup files:

# /etc/default/tftpd-hpa

TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/home/marc/ti-sdk05-am57xx-evm/filesystem/boot"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="--secure --create --listen"
RUN_DEAMON="yes"

marc@ubuntu:~$ cat /etc/exports

# /etc/exports: the access control list for filesystems which may be exported

/home/marc/ti-sdk05-am57xx-evm/filesystem *(rw,nohide,insecure,no_subtree_check,async,no_root_squash)
/home/marc/ti-sdk05-am57xx-evm/targetNFS *(rw,nohide,insecure,no_subtree_check,async,no_root_squash)

I've restarted TFTP and NFS servers:

TFTP : sudo /etc/init.d/tftpd-hpa restart
NFS : sudo /etc/init.d/nfs-kernel-server restart

Using out-of-box u-boot settings with the following additions

setenv autoload no
setenv serverip 192.168.1.101
setenv rootpath /home/marc/ti-sdk05-am57xx-evm/filesystem
setenv nfsopts 'nolock,proto=udp'
setenv myargs 'setenv bootargs console=${console} ${optargs} root=/dev/nfs nfsroot=${serverip}:${rootpath},${nfsopts} rw ip=dhcp earlyprintk'
setenv uenvcmd dhcp; tftp ${loadaddr}; run myargs; tftp ${fdtaddr} ${fdtfile}; bootz ${loadaddr} - ${fdtaddr}

#setenv fdtfile devicetree-zImage-am57xx-evm-reva3.dtb

Question: why is ipaddr needed if i'm setup for DHCP?
Question: where does u-boot get the names of zImage, DTB, etc?

Hi,
Try this command from the u-boot console:

run netboot

The TI U-Boot environment provides a netboot macro to boot the board with using tftp and nfs as the root file system.

The tftpboot command needs parameters such as a filename and a load address, neither were provided so the command failed because the filename was undefined.

Here is the netboot macro:

netboot=echo Booting from network ...; setenv autoload no; dhcp; run netloadimage; run netloadfdt; run netargs; bootz ${loadaddr} - ${fdtaddr}

If you follow netboot macro you will see how it gets ip address (dhcp), calls a macro to load the kernel, calls another macro to load the dtb, sets up the nfs args and finally boots the kernel with accompanying dtb. These other macros are defined in the printenv command earlier in this thread.

Best Regards,
Schuyler

Schuyler,

Thanks for the response. I am still having issues. I tried 'run netboot', see log. I also set the 'tdtfile am57xx-evm.dtb' and 'bootfile zImage'. These files are in /tftpboot directory. See output log. I also added the printenv output below.

Can you verify that my settings are correct?

Schuyler,

I have TFTP working but I am not mounting the NFS? u-boot environment settings and boot log below.

no error messages.
Is there a way to ‘sync’ NFS?
I tried running the ‘boot’ and ‘netboot’ commands – no good.
I restarted the nfs server – no good.
>> cat /etc/exports – shows proper ../targetNFS
>> mount – does not show targetNFS

u-boot printenv:

Schuyler,
I was able to get NFS working. I believe the issue was ownership. I changed targetNFS to user.user instead of root.root. I run the ./setup.sh as sudo, it extracts the targetNFS as root.root.

Does this make sense?
