 General Description
Samsung's S3C4530A 16/32-bit RISC microcontroller is a cost-effective, high-performance microcontroller solution for Ethernet-based systems. An integrated Ethernet controller, the S3C4530A, is designed for use in managed communication hubs and routers.
The S3C4530A is built around an outstanding CPU core: the 16/32-bit ARM7TDMI RISC processor designed by Advanced RISC Machines, Ltd. The ARM7TDMI core is a low-power, general purpose microprocessor macro-cell that was developed for use in application-specific and custom-specific integrated circuits. Its simple, elegant, and fully static design is particularly suitable for cost-sensitive and power-sensitive applications.
The S3C4530A offers a configurable 8-Kbyte unified cache/SRAM and Ethernet controller which reduces total system cost. Most of the on-chip function blocks have been designed using an HDL synthesizer and the S3C4530A has been fully verified in Samsung's state-of-the-art ASIC test environment. Important peripheral functions include two HDLC channels with buffer descriptor, two UART channels with full modem interface signal and 32byte buffer, 2-channel GDMA, two 32-bit timers, and 26 programmable I/O ports. On-board logic includes an interrupt controller, DRAM/ SDRAM controller, and a controller for ROM/SRAM and flash memory. The System Manager includes an internal 32-bit system bus arbiter and an external memory controller. The following integrated on-chip functions are described in detail in this user's manual:

Der 10/100Mb/s Switch ist ein

Broadcom
BCM5324MKPBG
HC0622 P12
785357 P2

Das heisst leider: Schlechte Doku!

• http://www.broadcom.com/products/Small-Medium-Business/Fast-Ethernet-Switching-Products/BCM5324M

Eventuell gibt es aber ein paar Linux ansätze für irgendwas davon.
Dann steht der eigenen Firmware nichts mehr im wege!

eventuell KÖNNTE man den Openwrt Treiber für den BCM5325/BCM536x Erweitern und Nutzen!

• https://dev.openwrt.org/browser/tags/whiterussian_0.9/target/linux/package/switch/src/switch-robo.c

werden wir wohl mal das Zeug was wir haben dissassemblieren!

Bei den Gbit/s Pots gibt es zwei extra Chips auf denen die Kühlkörper mit wärmeleitkleber befestigt sind, desshabl weiss ich nicht was sich darunter verbirgt. Ich möchte ungern die Chips mitsamt dem Kühler durch mechanische gewalt von der Platine lösen.

So nun Wir haben zwei Switchs derselben Sorte hier im Haus. Dachte ich zu Anfang jedenfalls. Tatsächlich stellte sich aber beim configurieren der Geräte heraus das die Firmware unterschiedlich ist. Darauf hin dann das es sich bei den Geräten, warum auch immer einmal um einen ES5224RS+ und einemal um einen ES5224RM+ Handelt, welcher neuerer und wesentlich besser ausgestattet ist.

Da aber die Hardware bis auf das vorhandensein einer Seriellen Schnittstelle identisch ist kam ich auf die Idee einfach die Firmware bei der Firma anzufordern und auf dem RS+ einzuspielen. Leider liess sich die Firmware aber nicht so einfach ordern.

Also beschloss ich einmal den switch genauer zu untersuchen. Ich öffente den RM+ mit der Seriellen Schnitstelle und steiss auf einen Jumper in der näher der CPU (CPU info siehe oben)

[ Bild ]

Nachdem ich diesen entfernt hatte fand ich zunächst das auch “normal” zugängliche bios, in dem man neue Firmware einspielen kann.

Nach einem Neustart liess ich die Firmware normal booten und staunte nicht schlecht als ich schliesslich eine promt erhielt. aber nicht den “normalen” telnet promt zum configurieren des Switchs.

Mit ifconfig kann man die netzwerkkarte configurieren, und mit tftp daten übertragen ein nfs Laufwerk zu mounten scheitert mit der meldung das es keine nfs unterstützung gibt.

Also ARM binarys der gängigen programme suchen und mit tftp übertragen!

from http://opensrc.sec.samsung.com/

 	
the linux-2.6.4-hsc1 patch is announced
	
	
Hyok S. Choi announced the MMU-less ARM patch against linux-2.6.4 kernel, linux-2.6.4-hsc1.patch.gz on the download section.

This port includes ATMEL AT91xx(ARM7TDMI) platform support, which means GDB/ARMulator is supported also. And proc-arm940.S is included. (contributed by Hee-Chul Yun)

This patch is pending for being merged to 2.6.4-uc0 patch of uClinux developer team. 

openwrt runs on AT91xx * http://downloads.openwrt.org/snapshots/

Also wollen wir mal testen. . .

• http://mailman.uclinux.org/pipermail/uclinux-dev/2005-August/034302.html Patch für die Netzwerkkarte
• http://mailman.uclinux.org/pipermail/uclinux-dev/2003-December/023191.html

• http://sourceforge.net/projects/bios-lt/ Das Bios für das Teil
• http://www.ixo.de/info/zyxel_uclinux/ Das bringt danna uch die erklärung wie man den code compiliert.

   ARCH := armnommu
   CROSS_COMPILE = arm-elf-

• http://mailman.uclinux.org/pipermail/uclinux-dev/2004-October/028930.html S3C4530 und der MTD driver

Irgend ein Simu

• http://www.skyeye.org/

Auf dem Weg zu nem cross compilerr lief mir noch so eien fehler über den weg error: array type has incomplete element type hier die Lösung:

• http://lists.osdl.org/pipermail/kernel-janitors/2005-May/004092.html

• http://www.ixo.de/info/zyxel_uclinux/ uclinux auf einem Zyxel (auch SC34510B)

Also nach tagelangem, interessantem aber leider fruchtlosem gebastel: man nehme die 2.00 Firmware von http://www.rubytech.com.tw/EN/download.php für den “L2 Managed FE Switch-ES-2126C”
Und kanns diese auf EDIMAX ES5224RM+ Switchs einspielen.
Kann aber sein dass man damit ein Backdate macht, denn die Edimax Firmware gibt sich als V 2.23 aus.

Natürlich übernehme ich hier wiedermal keien Haftung. Ist euer Bier und nur nen Idee von mir.

das mit / ist 0xD6F18 oder 880408 dann gibt es noch einen -rom1fs- Eintrag bei 0x3F904 oder 260358 und einen 0x7E530 oder 517424 bei f8D00 steht es nochmal drin, ist aber nur im mount binary oder in ner lib, wo alle möglichen FS Typen gelistet sind. lassen sich aber alle nicht mounten.

wenn da mal kein linux ist. und Linux ist GPL! Ruby Tech und Edimax verletzen dei GPL!

ok, da ist noch ein bisschen magie dabei

• http://mailman.uclinux.org/pipermail/uclinux-dev/2004-July/027364.html

eventuell das image vor das rom kitten und dass dann übertragen?

Also wenn das so nciht geht, JTAGgen!

• http://www.reseaucitoyen.be/wiki/index.php/Samsung4510
• http://hri.sourceforge.net/tools/openwince.html JTAG the Samsung4510

JTAG tolls also mit den zwei patches für den S3C4510b applied und compiliert, ein paar änderungen an den Device files, und schon erkennt er alles automatisch.

so nimmt man nun den atftp von gentoo dann kann man damit auch Dateien richtig zu dem teil übertragen. der atftd von debian Etch geht definitiv nicht! weiss der Geier warum! Dann nimmt man noch das ungezippte rubytech image und gebe das das edimax zum booten, dann bootet er auch!

mit [Ctrl]+[c] kann man übrigens den bootvorgang unterbrachen und bekommt die shell auf der Seriellen.

Start: no need to update flash..
User: no need to update flash..
# 
# 
# ls
bin   dev   etc   home  lib   mnt   proc  tmp   usr   var   

so, mal sehen ob es wirklich eine andere Firmware jetzt ist. .

Naja, gut, ich dachte er würde nicht booten! tut er aber doch! nur loggt er alles zu ttyS0 !! und das ist nicht zugänglich, es sei denn man Lötet! und das habe ich getan! an die TX und RX pins vom Samsung nen MAX232 dran und man bekommt was.

Kernel panic: VFS: Unable to mount root fs on 1f:03

Ok, das er kein RootFS findet ist klar, weil keins da ist. und schon garkein jffs2 das war jetzt das uCrouter image für nen anderen AP

— Bernd 2007/03/27 01:15

nimmt man einen Kernel vom Dell-True_mobile_1184 (R51714.EXE) der auf mit einem Linux auf einem s3c4510 läuft und bastelt sich selbst ein romfs dran, dann kann man das auch booten. und man bekommt einen promt, wenn man alles richtig macht. leider taugt der kenel nicht für den switch, weil er keine module für den switch einkompiliert hat.

• http://wiki.kuban.tv/doku.php?id=hack:firmwareanalysis anderer Firmware hack

im WRT54G_1.02.1_US_code.bin soll eine busybox stecken, die versuche ich mal zu extraieren. im image ist ein cramfs drin

kann ich aber leider vergessen, weil das ist MIPS und kein BFLT binary!

#cramfs
update für /dev/mtdblock1

-Compressed ROMFS
-mountbar auf der box oder auf big endian systemen.
-um updates zu mounten mit einem hexeditor  (big endian, also verkehrtrum) nach "28 CD 3D 45" suchen und alles vor der 28 löschen
mount -t cramfs -o loop mein.wsw /mnt2
- oder den offsset an der 28 rausfinden und -o loop, ofsset=<offset>

Nach der 4-Byte-Magic (0x28cd3d45) folgt die totale Länge (4 bytes, big-endian?) des cramfs. Hier ein Auszug aus cramfs_fs.h:


/*
* Superblock information at the beginning of the FS.
*/
struct cramfs_super {
u32 magic; /* 0x28cd3d45 - random number */
u32 size; /* length in bytes */
u32 flags; /* feature flags */
u32 future; /* reserved for future use */
u8 signature[16]; /* "Compressed ROMFS" */
struct cramfs_info fsid; /* unique filesystem info */
u8 name[16]; /* user-defined name */
struct cramfs_inode root; /* root inode data */
