#38 Re: 全志 SOC » 请教arm linux在 windows链接出错问题 » 2018-03-19 14:42:45

根据上面两个关键字,找到这里
Android.mk文件语法详述

(6). LOCAL_SHORT_COMMANDS := true /flase

       当你的module有很多的源文件,或者依赖很多的静态或动态库。这会强制编译系统使用一个中间的列表文件,并通过@$(listfile) 语法和library archiver 或者 static    linker一起使用。

    这在Windows上是非常有用的,因为它的命令行只接收最大8191个字符,这对于复杂的工程来说太小了。

    这同样也会影响单个源文件的编译,如果将所有的编译器选项放在列表文件里面。

    注意如果设置了‘true’以外的值,都会恢复成默认行为。

    你也可以在Android.mk文件中定义APP_SHORT_COMMANDS来强制使你的工程中的所有modules使用这项功能

    注意:默认我们不推荐启用这个功能,因为它会使得编译变慢。

    该变量可以解决如下编译问题:make: execvp: /home/android-ndk-r9d/toolchains/arm-linux-androideabi-4.6/prebuilt/windows-x86_64/bin/arm-linux-                      androideabi-g++: Argument list too long

          特别注意:

      APP_SHORT_COMMANDS , LOCAL_SHORT_COMMANDS 可以解决链接时参数太长的问题(生成*.a *.so时中间文件过多)

       然而,编译,生成 libcrypto.so时,

在libcrypto模块中采用LOCAL_SHORT_COMMANDS:=true来指定会导致编译错误
在Application.mk中指定 APP_SHORT_COMMANDS:=true可以顺利编译,链接

Android.mk
LOCAL_SHORT_COMMANDS := true 

Application.mk
APP_SHORT_COMMANDS := true

5.14 官方就发现了这个问题,提供了补丁, 但是 5.24a 又老毛病又犯了.

http://www.keil.com/support/docs/3795.htm

SYMPTOM
When a new µVision project is created with Project - New µVision Project... and a project is already loaded, it is possible that µVision reports the error Encountered an improper argument under some circumstances for specific microcontrollers. Under Windows XP it is even possible that µVision crashes in this situation.



CAUSE
There was an issue in µVision version 5.14.2.0 which has been identified and fixed.

RESOLUTION
Download the attached file and extract it to the folder C:\Keil_v5\UV4. If you have installed PK51 to a different folder, you need to adapt the path accordingly. The file UV4.exe is replaced with version 5.14.2.1.

PK51 versions later than 9.54a will include this µVision update.

有一个u盘, s3c2416和电脑都可以读写, 但是用V3s出现这个提示,

格过了, 还是不行

供电应该没有问题,
另一个U盘正常。
有没有办法解决?

Linux的启动log是这样:

上面V3s启动错误的终于找到问题了, 打死我都没想到是这个全新芯片的问题。
我把两块板子交换V3s芯片,
不正常的板子变正常了,
正常的板子变不正常了, 和上面出现的问题一模一样.

芯片有可能焊坏,当然也不排除全志芯片出厂检验不严格。

#72 Re: 全志 SOC » 试着v3s从spi nand启动,读取rootfs数据出错。 » 2018-03-02 15:18:21

是yaffs2吗?

你试一试这样,
弄一个rootfs ramdisk, 与zImage一起打包那种方式,
先把shell启动,然后再mount这个文件系统试一试。

谢谢楼上两位, 终于解决这个问题了, 用SDL_PIXELFORMAT_RGB565 也可以了.

代码稍微改一点点,就是用那个 memcpy

板子只改了一点重新做了一次板子, 基本没改过V3s附件元器件,
奇怪旧版4片板子都没这个问题,
刚刚试过了, 连续50次重启旧板都正常。

感觉应该是硬件问题,
把 CPU旁边的1.2V和1.8V都焊上电容,
还是没什么卵用,
把V3s重新拖焊一下也是如此,不过概率小很多了。

1. 进入u-boot命令行,bootcmd, bootargs参数均为空,那启动的时候怎么加载dts和kernel,rootfs的呢?
2. Widora dts文件Widora.dtb是不是和kernel一起打包的?如果一起打包的怎样让uboot加载dtb, 启动的时候dtb加载的地址是什么?

widora_mode repeater:
是中继, 你就把widora当成一个放大器好了。你连上widora获取到的ip,网关就是上级路由器给的。

widora_mode client :
这种就是路由器级联, 把widora当下以一级路由器。你连上widora获取到的ip,网管就是widora给的。

#89 Re: 全志 SOC » 有人知道全志的.fex格式是啥吗?比如u-boot.fex和u-boot.bin有什么区别?全志的pack脚本到底干了啥?有高手提点一下吗? » 2018-01-12 08:40:27

解决了,感谢大家的帮助,分享一下过程吧。
1.对于新用全志平台的朋友来说,比如我,先了解一下sys_config机制,其实就是类似主流的dts,全志linux内核里有script_get_item之类的程序也是对应主流linux的设备树解析函数
2.看了u-boot的源码,发现很多设备信息都是空的,也没有其他函数来填充初始化
3.虽然全志自己搞的一套脚本很烦,但是既然要用还是得研究研究,比如这次,一般来说编译完的u-boot就可以直接使用,但是全志的不一样,需要用pack脚本把sys_config里面的配置信息添加进去,生成u-boot.fex,这才是烧写文件

再请教一下,是不是做SD启动卡,一定要用全志的pack脚本。现在比如我没有android,只有linux kernel,u-boot,那么打包出来的东西用phoenixcard做出来能启动板子吗?谢谢

因为我们买的V3开发板,他们给的SDK是android的,我们打算用自己的linux,所以我就打算单独做SD卡启动,没用他们给的pack脚本

可是我看源码,第一句"HELLO! BOOT0 is starting!\n"都没打出来....肯定是串口初始化就失败了,要么就是串口不对
