How to make a Linux image run?

thaip

Hello,

I'm sorry to post a question in English here. As this is the only forum talks about skyeye. I'm Vietnamese, not a native-English speaker. Hence my English might be not really good.

Because I'm totally new to embedded software development, therefore I choose skyeye as a practice environment. However, I have some problems since the very first step. I download the uClinux source code from the website, then compile it with arm-linux toolchain. After several errors and failures, I can make an image without any problem. Then I use that image with a default skyeye.conf got from testsuite2/at91/uclinux_cs8900a. Unfortunately, the image is loaded successfully and it hangs without showing the command prompt.

When running make xconfig, I choose GDB for the vendor and Skyeye for the product and leave other options as default. I follow the link http://opensrc.sec.samsung.com/Getting_Familiar_with_uClinuxARM2_6.html to do this.

Below is the screen log:

If any of you have seen this problem, please show me how to fix it. Beside that, please share with me the document about the commands in skyeye.conf if you have it.

I appreciate any answers.

Thanks,
Thai.
