Nah lho! Weekend ini mo bingung bingung sekalian dah! Tinggal pilih yg
mana yg memiliki efisiensi battery better. Dan yg mana yg punya
browser yg paling compatible dgn PC. Secara sudah ditemukan beberapa
web yg tidak bisa dibuka di latest Android.

PALM PRE RUN ANDROID AS ALTERNATIVE
Yes, you’ve read it right. And not only Android. OpenMoko is being ported too.
So what is this nonsense? I will explain. While doing research on the
technology behind Palm Pre processor I have uncovered something that I
did not expect to see. It turns out Texas Instruments provided a
development device based on OMAP3430 processor called Zoom™ OMAP34x
Mobile Development Kit (MDK). I will not bore you with the
specifications of this device since you can follow the link to find
out more, however, one of the documents on this page attracted my
attention. I quote OMAP 3 SOM-LV Product Brief document from that link
“By starting with the corresponding ZoomTM OMAP35x Development Kit or
Zoom OMAP34x Mobile Development Kit, engineers can write application
software on the same hardware that will be used in the final product”
which means that software developed on the Zoom MDK should, in theory,
work on any OMAP3430 device.
Now for the juicy part. Following the release of the Zoom MDK device,
OmapZoom project was formed to gather OMAP developers together to work
on an open-source project. Of course, one of the projects within
OmapZoom is porting Android on the OMAP 3 system. And they have
succeeded. There are instructions on how to install Android on Zoom
MDK at the Omap Zoom Android page together with the helpful Beginners
Guide here.
To get started you would need to be running Linux (i386) operating
system with all the necessary software listed in the Omap Android
Beginners Guide:
* Git 1.5.4 or newer and the GNU Privacy Guard
* JDK 5.0, update 12 or higher
* The following packages: flex, bison, gperf, libsdl-dev,
libesd0-dev, libwxgtk2.6-dev (optional), buildessential, zip, curl
* You might also want Valgrind, a tool that will help you find
memory leaks, stack corruption, array bounds overflows, etc.
Other tools that we would need are: 2 stage bootloader (u-boot and
x-loader), linux kernel and android filesystem.
The OMAP processor follows a 2 stage boot process. The first stage is
loaded into the internal static ram by the ROM code. Because the
internal static ram is very small (64k), the first stage loader is
needed to initialize memory and enough of the peripheral devices to
access and load the second stage loader into main memory. It is the
job of the second stage loader to initialize the remaining hardware
and prepare the system for kernel boot. For the visual process of how
2 boot stages work on OMAP processes please refer to Booting and
Flashing.
The main problem to overcome with Palm Pre will be the requirement of
serial connection to the device to access the initial boot loader and
kernel console to tell the device where to look for boot sector. The
way it works is the loader will look for boot sector in stages: NAND
–> SD card –> filesystem. If it finds a boot sector in NAND boot
partition (which will be WebOS) it will not look further. We would
need to acces the initial bootloader to change the boot partition.
Since developers were able to develop a serial over USB driver for
iPhone, which is a firmly closed system, it may be much easier to
develop the same driver for a device based on such an open system as
OMAP. I believe it is only a matter of time and we will see the
ability to access Palm Pre’s bootloader and linux core soon after its
release. This would open the possibility to (1) install various
operating systems like Android and OpenMoko and (2) develop native
applications for Palm Pre (similar to Cydya and Installer on iPhone
prior 2.0 software).
Now, you may have noticed that Android Beginners Guide only shows how
to install Android on SD card. As we are all well aware Palm Pre does
not have an SD card slot. This leaves us the option of partitioning
the NAND and installing Android there. There may be, however, another
option too. Palm Pre supports USB Mass Storage. We might be able to
install Android on a partition on the accessible part of the Palm Pre
user storage and then point the initial bootloader to that partition.
Android on OMAP project hints that this is indeed possible as we embed
Android in the original linux core. This means that with a native
application or execution of some scripts it can be possible to run
call Android OS within Palm WebOS, just like they have done it on
Nokia N810, which is also based on an older OMAP processor.
So the holy grail of dual boot of several operating systems on one
device may be a step closer now. Android on NokiaN810 and linux on
iPhone have made a great progress in this direction. Now Palm Pre can
join with a very good chance to succeed. Android project is only a
small part of OmapZoom. Guys over there are working on DSP driver,
OpenMax codecs, GSStreamer plugins and more. Check out OmapZoom for
yourself for more information and documentation.
