因为有了IP01,那么现在开始我对embedded linux学习进发,不知道大家是否有兴趣呢?

就算没有,大家也可以来看看,下的IP01的U-boot documentation

But the hardware still has limitation

The following link provides a very good introduction of embedded Linux.

Many members use IP01 in a productive environment. Might be it is better to choose other cheaper platform, like DD-WRT, which is more popular and easy to ...

看来难度比较高,不知道members是否有兴趣参与呢?

Since the initial setup for the Analogue blackfin development environment is completed, the next task is to study the way of writing simple programming code such as flashing the l.e.d on the IP01 box.

For me, it also took about 45 minutes to fresh compile before.  I recall, but not exactly sure, that we may choose to save all the files after completion.  In that case, it will drastically make the next compilation faster on top of the first one.

    I mean for the new version. For the recompilation, I understand this as after the first compilation, I have downloaded most files and make some of the modules. recompilation is just for the new option checked and make image.

You do not need to do so. You may shorten the developed by just modify the settings in the "make menuconfig" and then make it agin and followed by make image. That's all, the totoal time for these remakes took you about 10 minutes. It is pretty fast and not time consuming.

Everytime I make a clean compilation by removing all the old codes and then redownload by svn checkout.
This is why I take almost an hour to do so especially in between I forgot to check the option of CPU to compile.

I shall let you know later when I make another fresh compile after have made clean.

You mean second compilation is an additional option enable not a fresh one. I read from the developer that he tooks 10+ min for a fresh compilation.

A bit too slow for our old or ATOM CPU.

CK,

The first compilation using my old IBM T43 notebook took about 45 minutes to complete the process. For the second compilation after having enabled g729 option, it took less time to do, it was around ten minutes.

YH,

How long do you need to compile? For me on an ATOM 330, it takes quite some times, initially downloading and then compilation
