3D capable Android 2.2 Smartphones

Lately all the rage was for 3D high definition televisions, but now 3D is also coming to mobile handsets. Softbank will release 2 smartphones – “Galapagos 003SH” and “Galapagos 005SH” – in Japan between the end of 2010 and spring 2011. The smartphones will run Android 2.2 on a platform based on Qualcomm MSM8255 @ 1Ghz, feature a 3.8″ display and the capability to record HD videos (720p maximum). The main differences between the 2 handsets are that Galapagos 005SH will have a slide-out keyboard and a built-in 8 Megapixel camera whereas 003SH won’t have the keyboard but the camera will be 9.6 Megapixel. Both handsets will be manufactured by Sharp which also owns the 3D technology. The 3D images and videos will be viewable with the naked eyes, i.e. you won’t have to wear glasses. This will be used for picture, videos and 3D games. The smartphones will be […]

Default root password for sigma designs smp86xx boards

I have seen some people google for the default root password for sigma designs boards and they ended up in this blog without any answer. So I’ll provide some kind of answer. In the serial port console, once you get to the username/password prompt, the root password is… there is none, just press “Enter”. This is the default behavior in Sigma Designs SDK, it’s quite possible the root password has been changed for the device you are trying to access. In case telnet or ssh is enabled, you may try one of the default users in /etc/password, that may not have been disabled by the development team e.g. ftp, man, nobody,default, etc… and try to login without password, by just pressing “Enter” at the password prompt. Once you are logged-in as a normal user, type “su” to become super user, press “Enter” if you are being asked for a password. […]

Resources for Qualcomm MSM722x: MSM7225, MSM7227

Qualcomm MSM722x processors – part of MSM (Mobile Station Modem) series – are mainly used in mobile phones and to a lesser extend in tablets such as WellCoM A800. You won’t find any proper documents or information in Qualcomm website (see Qualcomm MSM page) except the following description: Qualcomm’s Mobile Station Modem™ (MSM™) chipset solutions enable cost-effective mobile handsets with advanced capabilities that leverage 3G technology yet minimize development time. Offered on four discrete platforms for tailored functionality, each chipset is integrated with a select set of features from Qualcomm’s multimedia suite of applications to enrich the user experience while maintaining cost-target objectives. So if you plan on developing on that platform, you’ll need to visit Qualcomm developer website to get most of the information you’ll need. There are two chipsets with similar characteristics. MSM7225 The MSM7225 chipset includes a 528 MHz ARM11 processor with a floating point unit (FPU). […]

WellcoM WePad A800 Android 2.2 Tablet Video Review

More and more decent (e.g. with capacitive multi-touch screen, decent processor…) and cost-effective android tablets are hitting the market such as Archos Gen8 Series. It might be difficult to obtain Archos 70 in some countries in Asia. But not is all lost as product such as the WellcoM WePad A800 are available in Thailand (and probably other countries).

Socket Programming: Client crashes when exiting server

One of our digital signage applications was crashing when the control server was shutdown at the same time a command was sent with no apparent reason. It would always crash inside the write function (see code below) and no error message were returned. sent = write(fd, buf, n); After a while, we found that in case the connection with the server is lost, and write tries to access the server, it will generate a SIGPIPE signal and in most systems, the application would just exit by default. A simple way to handle this case was to ignore the pipe signal by adding the following line during initialization: signal(SIGPIPE, SIG_IGN); In case the server is down at the time the write function is called, the signal SIGPIPE would be ignored, write would return -1 and errno should return 32 (Broken pipe). Alternatively, if needs be you could also handle the SIGPIPE […]

Archos 101 Archos 70 with Android 2.2

In the previous blog post about Archos 70 Video Review, I mentioned the device was running on Android 2.2. This is not currently accurate, as the device now ships with Android 2.1, but will be upgradable to Android 2.2 soon after. [ad#Google Adsense – Wide Banner] In the meantime, here’s an another Charbax’s video about Archos Gen8 devices (i.e. Archos 28,Archos 32, Archos 43, Archos 70and Archos 101) running a beta version of Android 2.2 for this series of devices.

Finding a device IP Address

If you are developing software for an Ethernet (or Wifi) device, you’ll need to access the board for debugging and/or testing purpose. If your board does not have user interface or the serial port is not available, you’ll have to find the IP address (assuming it is using DHCP) before accessing the board thru telnet or ssh. A simple way to do that is to ping the broadcast address and check the arp table. > ping -b 192.168.0.255 WARNING: pinging broadcast address PING 192.168.0.255 (192.168.0.255) 56(84) bytes of data. 64 bytes from 192.168.0.246: icmp_seq=0 ttl=64 time=0.018 ms 64 bytes from 192.168.0.101: icmp_seq=0 ttl=64 time=0.217 ms (DUP!) 64 bytes from 192.168.0.246: icmp_seq=1 ttl=64 time=0.023 ms > arp -i eth0 arp -i eth1 Address HWtype HWaddress Flags Mask Iface 192.168.0.103 ether 00:50:FC:00:00:01 C eth1 192.168.0.109 ether 00:13:20:01:01:01 C eth1 If you cannot find your device, it may be configured to […]
