similar to: downloading Centos to thumb drive?

I was doing a laptop repair job today and needed to boot from a USB thumb drive, in order to free up the CD/DVD burner. Fortunately, the laptop to be repaired permitted one to boot from a USB thumb drive. However, there are still PCs out there that can't boot from a thumb drive (I have two), so I was wondering if it's pos to use the CHAIN module to boot from a thumb drive ? I looked at

I took the "everything" iso and did the dd command to my 16G thumb drive. I booted and entered my usual ks=http://xxx on the boot line. All good so far. It gets my kickstart file and installation begins. At some point it says Installing libreoffice-opensymbol-fonts (492/1948) Retrying download of 1:libreoffice-opensymbol-fonts-5.3.6.1-21.el7.norarch then after 10 retries it fails. I

I have created a custom kernel as I needed to add floating point emulation to the kernel. I used the command below to create my initrd: mkinitrd --preload=ohci-hcd --preload=uhci-hcd --preload=ehci-hcd --preload=ext3 --preload=jbd --preload=scsi_mod --preload=sd_mod --preload=ata_piix --preload=libata /boot/initrd-2.6.9-67.ELmsgnet.img 2.6.9-67.ELmsgnet When I copy my vmlinuz and initrd to

I am running CentOS 4.7. I have a USB flash (thumb) drive that has a bunch of files placed there by Windows. I plugged it into the CentOS machine, and when I listed the files under "/media/usb-name", there was nothing there. I created an empty file: touch blah and it showed up when I did list it. I noticed, checking dmesg that it was attached to /dev/sdb. So I did a quick

Hi Koan, In general, this looks OK to me. Please split the patch into separate pieces, one for each issue you're addressing, though. From your description, it sounds like this should be 4 patches. That way we have a cleaner revision history in svn. -Jim On May 12, 2011, at 10:42 PM, Koan-Sin Tan wrote: > Hi, > > We are trying to use clang as a drop-in replacement for the gcc come

Hi I would like to use clang to cross compile the ARM binary. I hope the target binary contains both arm and thumb instruction sets. I use the flag -mhwdiv=arm,thumb. I compiled several binaries. However, I found that the thumb mode instructions are few. Even for very big program like gcc. The number of thumb mode instruction is less than 100. I get the ground truth from the mapping table.

Hi, We are trying to use clang as a drop-in replacement for the gcc come with Android NDK. I found that MC/ELF doesn't not handle Thumb functions properly, e.g., bit 0 of the function name in the .symtab is not set to 1, and some thumb instructions are not generated correctly, e.g., the addresses for tBL/tBLX are not calculated right. With that attached patch, we can compile and run some

Hi, I just realized that clang produces Thumb-2 instruction in code even when older CPU type which doesn't suport Thumb-2 is specified. Here is output: # /opt/llvm/bin/clang -S -ccc-host-triple arm-unknown-freebsd -mcpu=arm926ej-s -mfloat-abi=soft -v -o rrx.S rrx.c clang version 3.0 (http://llvm.org/git/clang.git 98138cdfdee05c0afbab2b209ce8cfe4a52474e1) Target: arm-unknown-freebsd Thread

I wonder if there are CDs available for purchase. I don't have any way to burn one from a downloaded iso image. Any help appreciated. Tom

Has anyone experimented with installing XCP from a USB thumb drive? Is it possible? How was the installation media installed to the USB thumb drive (e.g., dd)?

Thanks, Shankar. I needed to override all the places where st_value had been used, and it worked. But there another problem appeared: after correcting all atoms, I cannot distinguish between ARM and Thumb symbols in the further stages when fixing up relocations. I used to check targetVAddress (in terms of the relocation handler) since it contained 1 in the least bit when addressing Thumb

Hi all, When I use Clang, I can add -mno-thumb to the command line and Clang generates pure Arm code without any use of Thumb instructions. However, I am messing about with the Glasgow Haskell Compiler (GHC) which generates LLVM IR code directly and then calls `opt` and `llc` on that IR code. The generated IR code currently has: target datalayout =

Hi all, I'm trying to figure out a problem with relocation types 1 and 8 (as observed using otool -r on ARM/Thumb object files). Earlier, when I used LLVM 2.8 with llc to generate thumb (-march=thumb -mattr=+thumb2) assembly listings, then assemble those using the gcc of iPhone 4.2 SDK, there wasn't any problem. However starting with LLVM 2.9, the same toolchain emits slightly different

The llvm compiler can now generated movt/movw instructions to create 32-bit constants. Those new instructions use new relocations. Mach-o uses different numbering for relocations than ELF does. For mach-o, ARM_RELOC_PAIR=1 and ARM_RELOC_HALF=8. You need a newer linker that understands the new relocations. -Nick On Feb 20, 2012, at 5:20 AM, Harel Cain wrote: > Hi all, > > I'm

Hi everyone, I'm working on some custom transformation passes that have the side-effect of significantly increasing the code size. While testing it on some larger, real-world code bases, I run into a linker error for armv7 thumb code. The particular error I get from ld64 is that "armv7 has no pc-rel bx thumb instruction." I've been able to reproduce the problem by taking a

Hi Tim, Thank you for clarifying what the error actually means! I did read something about the BLX instruction but since I'm compiling strictly for thumb, it didn't make much sense to me. Adding -mdisable-tail-calls as a cc1 command indeed allowed me to link the generated binary. After looking some more at the ld64 source code, I came across the following comment: // The tail-call

Hello everyone, I want to generate machine code for target thumb, so run with bit code test.bc llc -march thumb test.bc -filetype obj -o test.o It doesn't generate test.o but show a message: "target doesn't support generation of this file type!"
