Hi,
I would like to ask a question with GUI support.
I am developing on OMAP L138 platform which has quite an amount of Linux resources from TI. The primarily purpose I am looking into Linux is for enabling Qt to build kind of an elegant user interface.
Meanwhile, I am also interested in BIOS, and there are some questions:
1. From the list of supported OS at http://en.wikipedia.org/wiki/Qt_(framework), it doesn't seem like Qt works on BIOS. Is it true?
2. Without Qt, is there other components that can be used to build professional-like UI based on BIOS?
3. Could anyone compare the learning curve/effort for
assuming zero basis on both?
Thanks,
Zheng
Selection of GUI framework depends on the kind of UI you want to develop. Qt is quite sophisticated and feature rich but comes at a cost. It's going to require a significant CPU and memory bandwidth.
1. Qt is not supported on BIOS
2. You can consider whether StarterWare is sufficient for your needs. It comes with a basic graphics library. I would assume it will be easy to port to BIOS
3. Linux + Qt - 1 week to understand the basics and write a hello world program. Probably another 4-6 weeks to understand what's required for your application and implement.
BIOS + GUI - Much simpler graphics package. 2 days for hello world and another 3 weeks for the UI development
The critical questions - what do you need and how much resources can be spared for graphics.

Qt is famouse and it is the foundation on which KDE is built on. Is it also what Andrioid relies on?
A big question for me is that I don't know how good(sufficient), or how bad(inadequate) the basic graphics library in Sitaraware is. The graphics library for my Sitaraware installation is at C:\Program Files\Texas Instruments\SitaraWare_01_00_00_09\grlib, and I see that it has a quite a number of commonly used graphic primitives, just like what one could find in the Toolbox of Microsoft Visual Studio Windows Form Designer. Given the richness of types, how well is the display effect? Is there any case showing for Sitaraware's graphics library? It makes me feel rather frustrated when exploring a graphics library without being able to see what its effect would be like.
Zheng,
You can download the latest versions from http://processors.wiki.ti.com/index.php/StarterWare. StarterWare graphics lib is ported from StellarisWare. It is good for basic graphics. To get an idea, you can download grlib_demo or game example from StarterWare (formerly SitaraWare) for OMAPL138 and load it on LogicPd evm.

Baskaran,
Thanks for referrring to the link, I will study the examples.
