W90P950bootloader启动内核的小问题

只看该作者 · 2010-8-14 21:40

小问题，**烦。
把950kernel下到0x8000，然后执行g 0x8000，系统可以正常启动。
把950kernel.zip下载到Flash中：
ft 1 kernel 0xa0020000 0x8000 -azcx

然后reboot,结果显示下面的内容后就没有反应了:

怎么办?
内核下载到0x8000后能正常启动,说明内核文件是正确的.
Unzip image 1也没有报错,说明解压缩也是正常的,可执行的时候结果就不对.

Flash中的内容:
ootloader > ls
Image: 0 name:BOOT INFO base:0xA0010000 size:0x0000FFCC exec:0xA0010000 -f
Image: 1 name:kernel base:0xA0020000 size:0x000ED790 exec:0x00008000 -acxz
Image: 2 name:rootfs base:0xA0140000 size:0x00223000 exec:0xA0140000 -fr
rootfs是一个cramfs格式的系统.

系统正常启动的输出如下:

你能不能帮我看下J-LINK调试710的问题，我用的是710的开发板，那个.gdbinit我怎么弄都同有初始化正确啊

不压缩下载到flash里面看看。

3# 6019实验室
不压缩直接下到Flash：
ft 1 kernel 0xa0020000 0x8000 -acx

结果还是一样，无法启动。
是不是因为启动的时候没有设置r0、r1、r2三个寄存器所致？
原来用W90P710/745做项目的时候就碰到过这个问题，后来是自己写了个加载内核的程序搞定的，当然我但是使用的内核是zImage，而不是.zip格式的。

在W90X900系列MCU上启动Linux，R0、R1、R2需要分别设置成哪个值？

你现在用的是zimage的？
这个不行的，你要用Image这个文件。

解释下我为什么没有设置R0、R1、R2.
由于华邦的bootloader是单独的，不会和任何内核进行沟通，所以新唐bootloader里面不会向kernel传递任何参数。
但是linux要求必须bootloader负责完成这个工作，所以我在移植linux的时候r0，r1是在kernel里面钉死了的。至于r2似乎最新的linux才需要设置r2的。所以你一定要用Image这个。因为zimage需要bootoader去解码的。而我们bootloader没这个功能。

用Image，直接下到Flash,可以启动.
不过,Flash就没有空间来放rootfs了.
