Configuring Middleware for Embedded Linux BSP


HI friends..

I have a question regarding installing middleware in embedded linux system..

I have a board from freescale based on ARM processor which is having Flash of size 256MB.I have BSP which is having ootloader,kernel,Device drivers,RFS... Now i Have to customize that BSP by adding some middleware like WxWidgets,Web browser,webserver,Media player,PDF viewer.etc,But when i go thru BLFS for these packages i found that the sizes of these packages are more like 100MB,500MB.....

Is there any way to configure these packages to reduce these sizes by limiting them to basic functionality.......

Please help me in this....

Thanks in Advance....

Regards,
Thiru

Often, no. The first thing that you need to do is to work out what packages are absolutely necessary. In thing like embedded system, it is unusual to need all that many GUI packages (web browser, pdf viewer, etc, etc) and those are the ones that take the most ROM. In particular, there can be packages which are nice to have, particularly for development, but which can be eliminated for the final product. You may find that having more memory for the development system is something that you have to do.

Your embedded system seems to need all of these big packages and that may be due to the unusual nature of your application, about which you have given no details.

When you have that minimum list, tou may well find that your application is impossible unless you have more ROM, but if you are close there may be some possibility by optimising things.
