+
+My involvement in Linux on mobile phones
+ 2003/2004: gpl-violations.org / Motorola A780
+ 2004: Started OpenEZX for A780 (now E680, A1200, E6, ...)

+Introduction
+
+
+Linux on mobile phones
+ is hardly something new
+ Vendors have been doing this since 2003, e.g.
+ Motorola EZX
+ (A760, A768, A780, E680, A1200, E6, ...)
+ Motorola MAGX
+ (ROKR2v8, ...)
+ lots of unknown Chinese vendors (E28, Haier, ..)
+ however, no 'really open' devices
+ proprietary UI libraries
+ proprietary kernel extensions
+ often no full source code
+ cryptographically locked down
+

+Openmoko
+
+
+Linux on mobile phones
+ Openmoko is many things
+ the hardware
+ GTA01 (Neo 1973)
+ GTA02 (Neo FreeRunner)
+ the various UI's
+ One GTK+ based)
+ One is a mixture of Qtopia, GTK+ and e17
+ One is FSO + e17 based
+ the distribution (based on Openembedded)
+ the company (Openmoko, Inc.)
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+Openmoko
+
+
+Why I'm not working on/for/with Openmoko hardware?
+
+ Not true, I still contribute to Openmoko :)
+ Linux kernel port is quite complete and stable
+ Hardware has its limits
+ GPRS-only (no EDGE, UMTS, HSDPA)
+ quite big and heavy
+ no option for keyboard
+

+Community based projects
+
+
+Linux mobile phone community ports
+
+ The vendor ships WM or other OS, community replaces it
+ xda-developers.com community
+ mostly focused on HTC devices
+ way too little developers fro too many devices
+ hardware product cycles getting shorter / faster
+ many new devices based on completely undocumented chipsets
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+Community based projects
+
+
+Linux mobile phone community ports
+
+ More smaller / fragmented projects
+ Most based on the fact that somebody bought the device and started osme hacking
+ Most are stuck
+ either in a quite early stage (kernel boots, not many drivers)
+ or advanced but hardware already end-of-life
+ Conclusion:
+ We need a new project with more prospect for success
+ Needs to be stable and full-feature while hardware still available

+Community based projects
+
+
+Linux mobile phone community ports
+
+ What if you want to start from scratch?
+ choose hardware that is as documented as possible
+ choose hardware where most peripherals have drivers
+ choose hardware that has good support in mainline Linux
+

+
+How to find such a Linux-friendly device?
+
+ Look at hardware details of available devices
+ Use Google to find out what hardware they use
+ Use FCC database to get PCB photographs
+ Look at WM firmware images (registry/...)
+ At some point you buy one and take it apart
+

+Linux-friendly hardware
+
+
+The E-TEN glofiish device family
+
+ various devices with different parameters
+ screen full-VGA or QVGA
+ EDGE-only, UMTS or HSDPA
+ keyboard or no keyboard
+ GPS or no GPS
+ Wifi or no Wifi
+ application processor is always the same (S3C2442)

+Linux-friendly hardware
+
+I went through this process
+ I found the E-TEN glofiish devices
+ They are very similar to Openmoko
+ Samsung S3C2442 SoC MCP with NAND+SDRAM
+ TD028TTEC1 full-VGA LCM
+ Other hardware parts reasonably supported/known
+ Marvell 8686/libertas WiFi (SPI attached)
+ SiRF GPS (UART attached)
+ CSR Bluetooth (UART attached)
+ Only some unknown parts
+ CPLD for power management and kbd matrix
+ Ericsson GSM Modem (AT commandset documented!)
+ Cameras (I don't really care)

+Project 'gnufiish'
+ Port Linux to the E-TEN glofiish devices
+ Initially to the M800 and X800
+ Almost all glofiish have very similar hardware
+ Openmoko merges all my patches in their kernel!
+ Official inclusion to Openmoko distribution

+JTAG pins
+
+ Find + use JTAG testpads
+ JTAG is basically a long shift register
+ Input, Output, Clock (TDI, TDO, TCK)
+ Therefore, you can try to shift data in and check if/where it comes out
+ Automatized JTAG search by project "jtagfinder" by Hunz (German CCC member)

+Serial console
+
+
+How to find the serial console
+ Just run some code that you think writes to it
+ Use a Scope to find typical patterns of a serial port
+ I haven't actually done (or needed) this on the glofiish yet, but on many other devices
+ RxD pin is harder to find, just trial+error usually works as soon as you have some interactive prompt that echo's the characters you write
+ Don't forget to add level shifter from 3.3/5V to RS232 levels

+What's HaRET
+
+What is HaRET
+ a Windows executable program for any WinCE based OS
+ offers a control interface on a TCP port
+ connect to it using haretconsole (python script) on Linux PC
+ supports a number of popular ARM based SoC (PXA, S3C, MSM)
+ features include
+ GPIO state and tracing
+ MMIO read/write
+ virtual/physical memory mapping
+ IRQ tracing (by redirecting IRQ vectors)
+ load Linux into ram and boot it from within WinCE
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Reverse Engineering and Porting Linux to a WM PDA Phone
+Using HaRET
+
+Using HaRET
+ run the program on the target device
+ connect to it using haretconsole over USB-Ethernet
+ read GPIO configuration
+ Create GPIO funciton map based on SoC data sheet
+ watch for GPIO changes
+ remove the signal from the noise
+ exclude unitneresting and frequently changing GPIOs
+ watch for GPIO changes while performing certain events
+ press every button and check
+ start/stop peripherals
+ insert/eject SD card
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Reverse Engineering and Porting Linux to a WM PDA Phone
+Using HaRET
+
+
+Using HARET
+ watch for IRQ changes/events
+ e.g. you see DMA3 interrupts while talking to the GSM
+ read MMIO config of DMA controller to determine user: SPI
+ read SPI controller configuration + DMA controller configuration
+ find RAM address of data buffers read/written by DMA
+ haretconsole writes logfiles
+ you can start to annotate the logfiles
+ of course, all of this could be done using JTAG, too.
+ but with HaRET, you mostly don't need it!!!

+Disassembling WinCE drivers
+
+
+Disassmbling WinCE drivers
+ is the obvious thing to do, right?
+ is actually not all that easy, since
+ WinCE doesn't allow you to read the DLLs
+ not via ActiveSync neither WinCE filesystem API's
+ Apparently, they are pre-linked and not real files anymore
+ luckily, there are tools in the 'ROM cooking' scene
+ hundreds of different tools, almost all need Windows PC
+ therefore, not useful to me
+ conclusion: Need to understand the ROM image format
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

+Disassembling WinCE ROM files
+
+Disassembling WinCE ROM files
+ 'datextract' to extract different portions like OS image
+ 'x520.pl' to remove spare NAND OOB sectors from image and get a file
+ split resulting image in bootsplash, cabarchive and disk image
+ 'xx1.pl' to split cabarchive into CAB files
+ 'partextract' to split disk image in partitions
+ 'SRPX2XIP.exe' (wine) to decompress XPRS compressed partition0+1
+ 'dumpxip.pl' to dump/recreate files in partition0 and 1
+ 'ImgfsToDump.exe' to dump/recreate files in partition2 (imagefs)

+Disassembling WinCE Drivers
+ Now we finally have the re-created DLL's with the drivers
+ Use your favourite debugger/disassembler to take them apart
+ I'm a big fan of IDA (Interactive Disassembler)
+ The only proprietary software that I license+use in 15 years
+ There's actually a Linux x86 version
+ Was even using it with qemu on my Powerbook some years back

+ spi.dll: The GSM Modem SPI driver
+ Sergsm.dll: S3C24xx UART driver, NOT for GSM
+ SerialCSR.dll: CSR Bluetooth driver
+ fm_si4700.dll: The FM Radio (I2C)

+Disassembling WinCE Drivers
+
+Disassembling WinCE drivers
+ Is typically hard, they're completely stripped
+ Windows drivers are very data-driven, not many symbols/functions
+ However, debug statements left by developers are always helpful
+ After some time you get used to it
+ You know your hardware and the IO register bases
+ take it from there, look at register configuration
+ What I've learned about WinCE driver development
+ ... would be an entirely separate talk
+ MSDN luckily has full API documentation
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%page
+Reverse Engineering and Porting Linux to a WM PDA Phone
+WinCE Registry
+
+
+WinCE has a registry, too
+ I never really understood what this registry is all about, but it doesn't matter ;)
+ You can use 'synce-registry' to dump it to Linux
+ Contains important information about
+ how drivers are interconnected
+ various configuration parameters of drivers
