QUESTION
I have a MIPS system (VSC7427) with u-boot and I am trying to boot a more recent kernel than the kernel provided by the vendor in their GPL release (which boots just fine).
The kernel FIT image appears to be sane, and judging by the output I think it should be bootable:
...ANSWER
Answered 2021-Apr-06 at 21:03The final problem you run in to:
ERROR: new format image overwritten - must RESET the board to recover
is because you've loaded the image in to memory in the same location as the entry point but you need to load it in to memory somewhere else so that U-Boot can unpack the image and put the contents where their load address is set to. Since you have 128MB of memory you should be able to put it at +32 or +64MB from start and then things should work.
QUESTION
I'm looking for a tool that can extract files by searching aggressively through a ZIP archive. The compressed files are preceded with LFHs but no CDHs are present. Unzip outputs an empty folder. I found one called 'binwalk' but even though it finds the hidden files inside ZIP archives it seems not to know how to extract them. Thank You in advance.
...ANSWER
Answered 2021-Jan-06 at 22:46You can try sunzip. It reads the zip file as a stream, and will extract files as it encounters the local headers and compressed data.
Use the -r option to retain the files decompressed in the event of an error. You will be left with a temporary directory starting with _z containing the extracted files, but with temporary, random names.

ANSWER
Answered 2019-Nov-29 at 10:54If you pull a random Arm Linux kernel (including Android) from somewhere and try to run it on anything other than the hardware that it is intended to boot on, the expected result is that it crashes very early in bootup without being able to output anything to screen or serial port, ie you get a black screen and nothing happens. The most likely situation here is that your image is fine and not corrupt, it's just not built to run on the vexpress-a9 board you're running it on.
In the unlikely event that this really is a kernel built for the vexpress-a9, the next problem you have is that you haven't passed QEMU a device tree blob via the -dtb option. Modern Linux kernels don't hardcode all the information about the boards they can run on, but instead expect the bootloader (which is QEMU in this case) to pass them a data file which provides information about where all the devices are for the board. If you don't do that, then the result is the same as above: kernel crashes very early in bootup without being able to output any information, so black screen.
QUESTION
I install qemu-system-arm in Ubuntu 16.04 to run firmware of dlink DIR868L. But when I use the command chroot ./squashfs-root/ /bin/sh, it just shows Illegal instruction. I get squashfs-root/from DIR868LB1_FW203b01.bin by binwalk and I am sure that /bin/sh exists in squashfs-root/.
I start qemu by sudo qemu-system-arm -M versatilepb -kernel vmlinuz-2.6.32-5-versatile -initrd initrd.img-2.6.32-5-versatile -hda debian_squeeze_armel_standard.qcow2 -append "root=/dev/sda1" -net nic -net tap and use scp to cpoy squashfs-root/ into virtual mechine. And I met the same problem when using debian_wheezy_armel_standard.qcow2
What should I do ? It has bothered me for the whole afternoon.
Or can anyone give me an example to run the arm firmware in qemu ? I only find lots of examples using firmware based on mips.
Thanks a lot !
...ANSWER
Answered 2018-Apr-23 at 17:09The problem is almost certainly because whatever CPU is in the DIR868lL is newer than the ARM926 CPU that the "versatilepb" board has. If the binaries from that firmware are built to use newer instructions, then running them in an emulation of an older CPU will result in an 'illegal instruction' signal, just as if you'd run them on real older ARM hardware.
This is similar to taking binaries that were built for a Core2 Duo and trying to run them on your old Pentium system: it won't work.
