I am trying to boot a DA830 REV A board that was shipped to me with U-Boot loaded without Linux. I was able to build DaVinci Linux and a root file system, and now I want to load Linux using tftp. I booted the board but am getting an error that "No ethernet was found.". Following is what the board starts up with:
SF: Detected W25Q32 with page size 4 KiB, total 4 MiB
In: serial
Out: serial
Err: serial
Net: Read from EEPROM # 0x50 failed
Board Net Initialization Failed
No ethernet found.
U-Boot >
I found one forum that suggested that the ethernet address was not set, and I checked with:
U-Boot > env print ethaddr
ethaddr=FF:FF:FF:FF:FF:FF
And indeed it is not set. I attempted set it with the following and got an error:
U-Boot > setenv ethaddr 01:02:03:04:05:06
Can't overwrite "ethaddr"
I also attempted to set it with the following, but it still does not set:
U-Boot > env set -f ethaddr 01:02:03:04:05:06
U-Boot > env print ethaddr
ethaddr=FF:FF:FF:FF:FF:FF
I don't know what to try next. Maybe my switches aren't configured properly??

Can anyone help me with formatting USB ?
The problem:

I'm trying to set up gem5 x86 full system on Mac OS Mojave (10.14)
First I did a git clone to get the gem5 sources, which are located at ~/gem5.
Then I ran scons build/x86/gem5.fast to build the whole thing. I had to change some of the -Werror flags to get it to compile, but it seems to work.
To test it, I ran build/x86/gem5.fast configs/example/se.py -c tests/test-progs/hello/bin/x86/linux/hello and got the following output:
gem5 Simulator System. http://gem5.org

I wanted to configure full system simulation, so I went to the "Full-System Stuff" section at http://gem5.org/Download and downloaded the Full System Files. I extracted the tar into ~/gem5/x86-system.
So now there's ~/gem5/x86-system/binaries which contains x86_64-vmlinux-2.6.22.9 and ~/gem5/x86-system/disks which contains linux-x86.img
In ~/.bash_profile I added export M5_PATH="/Users/me/gem5/x86-system".
However, when I run scons build/x86/tests/fast/quick, almost all of the tests fail. A lot of them have a failure like this:
...
File "/Users/me/gem5/configs/common/SysPaths.py", line 62, in __call__
raise IOError("Can't find a path to system files.")
IOError: Can't find a path to system files.
I also tried to run build/x86/gem5.fast configs/example/fs.py but I get the following error:
...
File "/Users/me/gem5/configs/common/SysPaths.py", line 71, in __call__
raise IOError("Can't find file '%s' on path." % filename)
IOError: Can't find file 'x86root.img' on path.
I'm not sure what part of configuration I'm missing. The docs and google searches aren't giving any working solutions...
when running GEM5 X86 in SE mode, I am trying to run bzip2 from SPEC2006, at first it was failing because it says it can't run dynamic execution so I compiled it with -static flag.
now I get this error:

I tried to find solutions in google but I didn't see any one referring to this problem, does anyone know how to fix the problem?
Please check your host machine configuration. Bzip2 does not work in a 32-bit machine. My desktop is dual core have 32-bit X86 architecture, I tried to run bzip2 it had shown same error.
my question about the installation of openshift environment using minishift on virtual box.
minishift v1.4.1+0f658ea
VirtualBox-5.1.26-117224-Win.exe
The installation is incomplete due to the folowing error:-
C:\Users\xyzdgs\Desktop\Openshift_n_Docker\OpenShift Developer>minishift.exe start --vm-driver=C:\Program Files\Oracle\VirtualBox\VBoxSVC.exe
-- Starting local OpenShift cluster using 'C:\Program' hypervisor ...
-- Minishift VM will be configured with ...

So, to solve this I simply put the directory where all drivers are located in the installation and run it again
C:\Users\xyzdgs\Desktop\Openshift_n_Docker\OpenShift Developer>minishift.exe start --vm-driver=C:\Program Files\Oracle\VirtualBox\

It says "machine does not exist", shouldn't the machine be created by minishift itself (see te procedure here: blog.novatec-gmbh.de/getting-started-minishift-openshift-origin-one-vm/)
Not sure what is causing this. Please guide.
The main issue with the command -- and what it's really complaining about -- is that you're passing in an unquoted path:
minishift.exe start --vm-driver=C:\Program Files\Oracle\VirtualBox\VBoxSVC.exe
should have been
minishift.exe start --vm-driver="C:\Program Files\Oracle\VirtualBox\VBoxSVC.exe"
But according to the MiniShift documentation, you should update to VirtualBox 5.1.12+ (which you have) and use the following syntax:
minishift.exe start --vm-driver=virtualbox
7 months after this question was asked and using VirtualBox v4.3.30, I can get MiniShift v1.15.1 running with the last command, but can't get it to accept your previous syntax or even produce the same error from it.
I'm trying to follow the instructions at syntaxnet's github page to build syntaxnet parser models.
My system is a Debian Wheezy. Shouldn't be very different from Ubuntu 14.04 LTS or 15.05. I have compiled bazel 0.2.2 (as opposed to 0.2.2b) from source and it appears to work correctly.
Whenever I launch the bazel test syntaxnet/... util/utf8/... command, no tests are executed (all skipped) with some quite cryptic error messages. Here's an example:
root#host:~/tensorflow_syntaxnet/models/syntaxnet# ../../bazel/output/bazel test syntaxnet/... util/utf8/...

Tried looking into the namespace-sandbox binary that's mentioned in the error message, but before I dive deep into this, I thought I'd ask here.

Command seems to work fine though:

Usage: /root/.cache/bazel/_bazel_root/install/ca381eaad1c931167a6355cb8a2b98cf/_embedded_binaries/namespace-sandbox [-S sandbox-root] -- command arg1
provided: /root/.cache/bazel/_bazel_root/install/ca381eaad1c931167a6355cb8a2b98cf/_embedded_binaries/namespace-sandbox
Mandatory arguments:
-S <sandbox-root> directory which will become the root of the sandbox
-- command to run inside sandbox, followed by arguments
Optional arguments:
-W <working-dir> working directory
-T <timeout> timeout after which the child process will be terminated with SIGTERM
-t <timeout> in case timeout occurs, how long to wait before killing the child with SIGKILL
-d <dir> create an empty directory in the sandbox
-M/-m <source/target> system directory to mount inside the sandbox
Multiple directories can be specified and each of them will be mounted readonly.
The -M option specifies which directory to mount, the -m option specifies where to
mount it in the sandbox.
-n if set, a new network namespace will be created
-r if set, make the uid/gid be root, otherwise use nobody
-D if set, debug info will be printed
-l <file> redirect stdout to a file
-L <file> redirect stderr to a file
#FILE read newline-separated arguments from FILE
Any idea?
UPDATE: I have done exactly the same steps on a Ubuntu 14.04 LTS (my small workstation, as opposed to the production server running Debian) and everything works well there, with all tests passing. I wonder what's the difference.
Apparently some permission errors happens when setting up the sandbox. A quick workaround is to deactivate the sandbox by using --genrule_strategy=standalone --spawn_strategy=standalone (note that the second one is already specified in the TensorFlow rc file).
You can set those flag in your ~/.bazelrc:
echo "build --genrule_strategy=standalone --spawn_strategy=standalone" >>~/.bazelrc
