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).  […]

ViewSonic Android Tablet: ViewPad 7

Lots of Android Tablet were shown at IFA 2010 in Berlin. The most hyped was Samsung Galaxy Tab. Charbax has lot of videos about different devices. Among them, ViewSonic Viewpad 7 seems to be worth looking at with Android 2.2, #G, Wifi, video calling, capacitive touch screen and a retail price that should be 399 Euros. It actually seems to be doing all what the pricey Samsung tablet is doing (except lower camcorder resolution). On the hardware side, it is most likely using Qualcomm MSM7227 (ARM11).

Digital Signage: Implementing a smooth scrolling text

Many digital signage hardware feature scroll text. However, in many cases the scrolling text is either not smooth, sometimes teared or very slow. It may depends on the performance of the hardware used but also on the implementation of the software. Once easy way to implemented scrolling text is just to redraw the text again and again at different position. However, this is very slow and yields poor results unless maybe you have a Truetype accelerator or similar hardware font accelerator. The next step is then to convert the text into pixmaps. This can either be done in the digital signage manager software (Windows PC/MAC or Linux based) or the digital signage player. Doing so in the latter makes it much more flexible. So you may create 2 pixmaps whose width and length match the region to be displayed, you write the text on those 2 pixmaps, then simply move […]
