Can anyone help me with formatting USB ?
The problem:
Error formatting volume:
Error wiping device: Command-line `wipefs -a "/dev/sda1"' exited with non-zero exit status 1: wipefs: error: /dev/sda1: probing initialization failed: Read-only file system

I'm new to kernel debugging, I'm trying to analyze the vmcore file using crash tool on RHEL 7. I'm trying to open the dump with below command.
crash /lib/debug/lib/modules/3.10.0-1160.80.1.el7.x86_64/vmlinux vmcore
but tools fails to load the vmcore with below error:
WARNING: kernel relocated [460MB]: patching 87472 gdb minimal_symbol values
crash: page excluded: kernel virtual address: ffffffffffffffff type: "possible"

please wait... (gathering kmem slab cache data)

I'm not sure this the vmcore file issue or crash tool issue. Can someone please help resolve this issue.
Thanks in advance
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
gem5 is copyrighted software; use the --copyright option for details.

**** REAL SIMULATION ****

Hello world!
Exiting # tick 5941500 because exiting with last active thread context
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...
I'm building a static library in objective-c, in Xcode 9 I could build without problem but I'm blocked in Xcode 10.
Initially I had these two problems that I resolved with the answers below
Xcode 10 Error: Multiple commands produce
Xcode 10: unable to attach DB error
Now I have this lipo error, and I already tried the solution of adding arm64 to the valid architecture and build only valid architecture
build settings pictures
** BUILD SUCCEEDED **
fatal error: lipo: can't open input file: /Users/Alex/Library/Developer/Xcode/DerivedData/myNewLibrary-gvpwgkkoffdnkybybgkafnqwepcx/Build/Products/Debug-iphoneos/arm64/myNewLibrary/myNewLibrary (No such file or directory)
Command PhaseScriptExecution failed with a nonzero exit code
Anyone have idea how to resolve ? thanks

What can I do? Please help

Your current error message states that the command "patch" is not found. I gues your mingw installation has not installed this programm. See Apply a patch file in Windows using Mingw how to install it.
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??
