Hello,
I'm quiet new to arago and the TI SDK, so I have some questions if I understood everything right.
I am using the AM335x-EVM-SK. The real hardware will change a bit, no MMC but a smaller NAND device. I aim to boot within 4 seconds and the image should 200MB or smaller, Qt is also needed. Do you think this is possible?
First some questions about arago. For example, the arago kernel is called ti-staging, that looks like still in development?
My arago builds (e.g. bitbake arago-base-tisdk-image) don't boot to the end and I ran into this
Hit any key to stop autoboot: 1 \0x08\0x08\0x08 0
mmc0 is current device
SD/MMC found on device 0

I could find this thread and it seems to be a known arago bug? Or am I wrong?
http://e2e.ti.com/support/embedded/linux/f/354/t/263058.aspx
Is it possible to use arago for the current stable versions (kernel 3.2 instead of the staging 3.8?).
After arago I tried to use the TI SDK.
I am able to boot both rootfs images (arago-base-tisdk-image-am335x-evm and tisdk-rootfs-image-am335x-evm), okay that is quite easy. Then I had a look how to install Qt to the rootfs, I think increasing the base image is better than shrinking the tisdk-image. When I understand it right, I have to install the Graphics SDK following this Link:
http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide
and afterwards I have to install Qt with the help of following Link
http://processors.wiki.ti.com/index.php/Building_Qt
My first question is, do I really need the Graphics SDK for Qt? I do not need OpenGL/3D, I need Qt just for some simple Applications (Buttons, Lineedit, shwoing an Image and so on...).
The second question is, to improve boot time I thought about a static kernel without any modules, I think this wouldn't be possible if I have to use the Graphics SDK due to the kernel modules omaplfb, pvrsrvkm, and bufferclass_ti?
Best regards
Falk
