其实.........很简单的,只要会编译内核和驱动就差不多啦,可惜..........这些我都不会。或者用OZ还有一些开源的系统,很多是2.6内核的,只不过软件没有pdaxrom多

改用debian就是2.6的,不过据说耗电大些,没测试过。

angstrom也是kernel 2.6,目前kernel 2.6上主要的进展在angstrom。
截止到目前,kernel 2.6尚不支持speedstep,如果原来没有用降频,在缺省频率下,kernel 2.6并不比kernel 2.4费电。

angstrom的系统做的很差,除了kernel,几乎没什么可用的。
目前要在7500上用kernel 2.6,唯一的选择是debian,除了不能降频/超频,debian把SD卡作为硬盘使用,倒是可以突破7500C NAND小的弱点。

oesf上刷kernel的方法,在c1000/c3XXX上都是支持Sharp loader,也就是OK模式。
7500上是uboot模式,比较麻烦,最好能在7500上用OK模式刷,会比较容易。

2.6相对2.4来说,linux的驱动函数的接口都变了 ,在短时间内机器的各个驱动不会都改过来,有些设备将缺少驱动.而且对手持设备来说,2.6对2.4没有差别.也没什么提高.

就算Moto的手机,硬件是pxa270,比zaurus还高,但也用的是2.4的kernel.

C1000以上是pxa270,2.6的提高是有的,速度快了。
但是好多接口都不稳定,现状是跑得快,但是经常跑出边了。
