Linux in ARM926EJ-S 248Mhz

So what that it supports ARM? The anyka is CPU is different the core is ARM, but other peripherals are completely unknown.

Android is just starting to be built into tablets and netbook computers. At this point, only phones are really supported - I am running it on my Nexus One phone. I also run Debian Linux on embedded ARM boards I work with. It works on systems with 32-64MB of RAM so your 128M system should work very well. If the system does not have a CD/DVD player, then you should be able to install from a USB thumb drive. You can get the minimal installation disc image from here: Debian -- Network install from a minimal CD and if you don't have a CD reader, then use Unetbootin to create a live USB drive from either Windows or Linux, which you can get from here: UNetbootin, Universal Netboot Installer | Download UNetbootin, Universal Netboot Installer software for free at SourceForge.net

while, i don't have a linux core,somebody try it.

Hi,

an "uncleany" way to get Linux working with Arm-WinCE is the following :
1/ have PocketDOS installed.
2/ find the Slackware Distro with umsdos file system (elderly version).
3/ have the loader loadlin.exe to load Slackware.
5/ enjoy!

An other safe way to run Linux on anyka devices :

1/ have a Java VM Sun compatible installed
2/ run JPC.jar, from the Java PC of the Oxford University, or from Sourceforge
3/ within the x86 PC emulator, launch DSL disto (Damn Small Linux)
5/ Enjoy ! ( but very slow )

It is also a safe way as with the above PocketDOS, because you run Linux in a Sand Box.

For people trying an Arm-Linux kernel directly, please MAKE EXTREMLY CAUTION as you are accessing the hardware diretly. Don't let your device without watch, risks known are the battery to explode or a compound making a fire in your house. This MAY happend, so your are told.

To play with x86 emulation with PocketDOS or JPC, the french shareware "WinImage" is very usefull to extract a kernel image from a "cdrom.iso" image,to create a cdrom iso image, or to create "file.img" images and so on. You can download freely this app.
Revive your old floppies 1.44MB of Linux to bareboot.img or ramdisk.img

x86 emu with PocketDOS shareware for Linux hints.
*************************************************************************************************************************************
- have the OEM version of PocketDOS for Windows Mobile 2.1 or higher, it is easy to decompress on an external SD Card in a PocketDOS folder ( doesn't need of activesync from a running PC to install .cab files). Clean it up to remove Mips, SH3 and SH4 files.

- download the mini-slackware distro umsdos named ZipSlack from 50 to 100MB according to the different versions.

- set the virtual DOS machine with :
. Msdos622.img (or .ima, it is the same) you can find on the Net if you have the license, if not try to find a 6.22 FreeDOS image or other flavor of DOS but bootable ( seems DOS ver 7.10 doesn't fit)

. from PocketDOS, create a virtual disk ZipSlack.hdd at least 150MB. You will have to create a partition on this HDD from your A:>\ virtual floppy with fdisk, and format it with A:>\format C:, of course the files fdisk.exe and format.com must be on your virtual 1,44Mb floppy. Inject then with WinImage the ZipSlack distro in a Linux folder of your brand new virtual HD on your PC.

. make sur you have a x86 32 bits virtual CPU in real mode running. Take the Bochs_CPU.dll or the DOsBOX_CPU.dll (elsewhere on the net, not in PocketDOS site). The Bochs_CPU worked for me having in PocketDOS Setting/system pointing on the Bochs_CPU.dll (remove other dll files) and max memory at all types ( this setting works for me and avoid hanging).

. load the barnum and check you have eventually a 486 DOS virtual machine with chkcpu121 (Check CPU version 1.21) in real mode working.

. you can also put your SD Card in an usb key SD Card reader and reconfigure PocketDOS A: and C: to make it works.

. launch the linux kernel with linux.bat, it take a certain time to load, to decompress and to boot, be patient and watch the messages on screen to discover possible mounting points.

Have fun !

x86 emu for Linux hints - part 2
********************************
if you experience geometry problems in loading the kernel, you may inject from WinImage to your SlackDisk.hdd the

Testdisk utility from Christophe Grenier, released as freeware. PocketDOS seems sometimes giving wrong Disk parameters.

x86 emu for Linux - comments
****************************
While the Knights have serious fun to get an Arm-distro booting the hardware, you should have fun at this point if you have mounted your root in ram or in loop.

Kernel messages like under should not be uncommon on your device :

FAT : bogus cluster size 31
UMSDOS: umsdos_read_super failed, mount aborted
sh-2021: reiserfs_read_super : can not find reiserfs on ramdisk (1,0)
Kernel panic : VFS : unable to mount root fs on 01:00

Even knights do not have working Anyka Linux boot distro.

x86 emu Linux - worth to try
****************************
SkaOS 2.0 from Bodo Giannone 1,44MB floppy image at [You must be registered and logged in to see this link.]
You may perhaps get :

VFS: Mounted root (minix filesystem)
Freeing unused kernel memory: 56k freed
init started: Busybox v0.60.5 (2007.01.31-21:32+0000) multi-call binary

The ramdisk that is loaded after contains X and may crash.

According to Bodo, SkatOS is not emulator friendly aside Qemu.

x86 emu Linux - WARNING
***************************
Please be carefull if you plan to test a graphical environment inside PocketDOS, it may crash and you may need to reinstall WInCE, if you have it and if your device unable a reinstall.. So I would suggest for the moment to limit experiments with PocketDOS to text mode only..QNX demodisk, a real time UN*X which runs in graphical mode, seems more friendly as it gives hints for technical service when it crashes..

JPC's sandbox from Oxford is much more reliable, but the problem is to get a Java VM suitable to run it under WinCE.

x86 emu Linux - settings working
********************************
- have a MS-DOS 8.0 compatible floppy image to boot in PocketDOS ( I used the floppy you can create with Windows Millenium, rem before each line of the autoexec.bat file)

- create with WinImage a 2MB88 floppy where you put the following files extracted from Slackware 7.1 :
* loadlin.exe
* bzImage ( choose the bare kernel)
* umsdos.gz from the rootdisks folder
* linux.bat, containing the following line :

loadlin bzImage initrd=umsdos.gz root=/dev/ram0

( note that rw is not specified)
- check the bootsector of the 2,88 floppy to be Win95/98
- boot PocketDOS by A:, go to the 2,88 floppy by B: and type linux

You may get :

VPS: Mounted root (Minix File System)
Freeing unused kernel memory : 60k freed
INIT : version 2.76 booting
none on /proc type proc (rw)
INIT: Entering runlevel 4

log now as root
cd .. to go to /
ls to list the directory and files :

bin cdrom etc lib proc sbin tmp var
boot dev floppy mnt root tag usr

You can now navigate in the directories and cat files to see their contents, and wait for the Knights to get a solution to get
Arm-Linux on your device.

Note that your ZipSlack HDD can't be seen for the moment (unable to read partition table for hda), and that loading the RAMDISK is a bit long.

x86 emu Linux - Slackware 8.1
=============================
Booting with A: WinME DOS 8.0 virtual floppy, going to C: your vitual HDD (partitionned and formated) with Zipslack installed, and where you have injected the following files with WinImage :

- bzImage the bare kernel
- initrd.img the ramdisk from the Isolinux directory
- linux.bat as follow : loadlin bzimage initrd=initrd.img root=/dev/ram0

you may mount an ext2 fs,and discover your environment :

cat /proc/meminfo

mem total 13MB

cat /proc/cpuinfo :

processor : 0
vendor_id : GenuineIntel
cpufamily : 4
model : 1
model name : 486 DX-50
stepping : 3
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exeption : yes
cpuid level : 1
flags : fpu
bogomips : 0,94

Next step would be to get a Pentium MMX @ 233MHz dll and at least a 250MB mem environment !

x86 emu Linux - Slackware 11.0
==============================
Booting with A: WinME DOS 8.0 virtual floppy, going to C: your vitual HDD (partitionned and formated) with Zipslack installed, and where you have injected the following files with WinImage :


- initrd.img the ramdisk from the Isolinux directory
- linux.bat as follow : loadlin vmlinuz initrd=initrd.img root=/dev/ram0 (could put nousb option)

start with C:\>linux

As you can notice, the size of the RAMDISK of newer Slackware versions are over our 16MB ram environment.

x86 emu
=======
with Slackware 11.0, we get :

root@slackware/#ls

bin etc lost+found root tmp
boot floppy mnt sbin usr
cdrom lib nfs sys var
dev linuxrc proc tag

Note : umsdos-progs : removed in Slackware 12 since 2.6.x kernels do not support this filesystem.

I would believe that the way to get further may be to compile bochs emulator sources for the WinCE OS, as it is also possible inside Bochs to choose higher CPU. Qemu would also be of interest to setup an Arm-machine and safely testing Arm-Linux

An other way could be from a living Slackware 12 or 13 install to create a booting image with a slim kernel and a very slim RAMDISK compressed image with ext2 file system as we do not have much mem under PocketDOS.

x86 emu
=======
Under PocketDOS environment with Slackware :

cat /dev/fd0 : nothing ! no A:\> driver !
cat /dev/fd1 : nothing ! no B:\> driver !
cat /dev/hda : nothing ! no C:\> driver !

and

ls /sys/devices/platform : nothing !

PocketDOS troubleshooting on PC 703 WinCE 5.0 @ 266MHz
######################################################

There seems to be a mess with the five graphical modes of PocketDOS to enable system
settings, refering to my hardware

Hope things are better with AK8802 WinCE 6.0

16 bits Linux ELKS (from PocketDOS Web site) on WM8505 WinCE 6.0 :

VFS: Mounted root (Minix Filesystem)
Loading init
ELKS 0.0.78
Login: root
Stand-alone shell (version 1.0)
>cd ..
>ls
CVS bin boot dev etc home mnt root tmp usr var

Doesn't fit on AK780x WinCE 5.0, the cpu.dll module is not loaded (and PocketDOS checks for a valid boot sector ELKS.DSK doesn't have)
------------------------------------------------------------------------------------All this seems to mean that for ARMLinux on Anyka devices we need sharp cpu and display drivers..

Here is an image of a NetKids WM8505 running a bit of Slackware 11 under PocketDOS trying to communicate with a PC703 AK780x with PuTTY. Devices are linked by a RJ45 ethernet wire. Work in progress, I suspect them to speak chinese together when I don't watch them
