Unusual USB Devices in Linux Kernel

Some USB devices (especially cheap ones) are not fully compatible with the USB Stack and when you connect such devices to your target board, the kernel may output errors similar to the one below even though most other devices work perfectly. sd 3:0:0:0: SCSI error: return code = 0x10070000 end_request: I/O error, dev sda, sector 0 Buffer I/O error on device sda, logical block 0 sd 3:0:0:0: SCSI error: return code = 0x10070000 end_request: I/O error, dev sda, sector 8 Buffer I/O error on device sda, logical block 1 sd 3:0:0:0: SCSI error: return code = 0x10070000 end_request: I/O error, dev sda, sector 16 sd 3:0:0:0: SCSI error: return code = 0x10070000 end_request: I/O error, dev sda, sector 24 sd 3:0:0:0: SCSI error: return code = 0x10070000 It previously happened to us with a IDE to USB adapter based on Super Top Bridge ( VID: 0x14CD / PID: 0x6600).

Installing Chrome OS with CD or USB

Chrome OS is a lightweight Linux distribution build around the Google Chrome Browser, it is not related to Google Chrome OS. I suppose they may have to change the name sometimes in the future. To install it, simply download Chrome OS Live CD to try it out on your hardware. Bear in mind this is a Release Candidate version (Chrome OS 0.9.576 RC released on 7th of December 2010) at this time so it should be relatively stable, but expect a few bugs. Here are the main software packages installed in Chrome OS: GNOME 2.30 desktop environment Google Chrome 9.0.576 web browser Google Picasa 2.7 photo manager OpenOffice.org 3.2 office suite GIMP 2.6 image editor Flash Player 10.1 plugin Wine Windows emulator 1.2 Pidgin 2.6 instant messenger Dashboard in browser (See screenshot below) Here are the system requirements of Chrome OS: Processor: Intel Pentium, Xeon or newer; AMD Duron, Athlon, […]

Languages, Unicode and Charset

If your application needs to support multiple languages or if it needs to support languages with different character sets such as simplified Chinese (GB2312, GBK, GB18030, HZ,..) or traditional Chinese(BIG5, HKSCS, EUC-TW) you’ll need to make yourself familiar with Unicode and the different character sets. In this article, we’ll focus on introducing character sets,  manipulating and converting charsets and the possible challenges you may encounter while handling Unicode text files. If you plan to support multiple languages, you’ll also have to internationalize your application, for example by using Po files for different languages, a Po file editor and possibly have the translations done in launchpad if your project is open source. But this would be another subject. Go for Unicode If you are building a new application make sure its structure is based on Unicode (UTF-8, UCS-2, UTF-16 or UTF-32 ) since those charsets can handle most written languages (UTF: […]

Sony NSX-24GT1 Google TV Tear Down

Nikkei Electronics has recently teared down Sony Google TV as seen at IFA 2010. They used Sony NSX-24GT1, a 24″ internet HD television powered by Google TV, for this little exercise. They found three boards: Power supply board at the upper left. Main board (“Android board”) at the lower left. TV board at the right. The SoC mounted on the TV board is Renesas Electronics Corp. EMMA3TL2 (MC-10157), an image processing SoC designed for digital TVs supporting ATSC (USA), DVB (Europe) and ARIB (Japan). Finally, they disassembled the TV to access the main board. It turned out that Sony NSX-24GT1 Google TV main board is based on Intel Atom CE4100 (center) and Foxconn is the manufacturer (lower right). Eight Samsung K4B1G0846F DRAM modules are mounted on the board (Right of Atom CE4100) and since each of the DRAM has a capacity of 128 Megabytes, the total memory capacity is 1 […]
