已解决---如何编译k2 32M 256M 无USB的纯净padavan固件

longone

用的是HANWCKF老大修改的代码，k2原版已经编译成功。现在想要编译个k2 32M 256M 无USB的纯净padavan固件。

/opt/rt-n56u/trunk/configs/boards/PSG1218/kernel-3.4.x.config

# CONFIG_RT2880_DRAM_16M is not set
# CONFIG_RT2880_DRAM_32M is not set
# CONFIG_RT2880_DRAM_64M is not set
# CONFIG_RT2880_DRAM_128M is not set
CONFIG_RT2880_DRAM_256M=y
CONFIG_RALINK_RAM_SIZE=256
CONFIG_RT2880_UART_57600=y

改成上面红色代码就可以了。FLASH能自动适应。
编译好了。

没编译过padavan，下次来试试。
不过刚去看了下GitHub，项目说明里说的很直白的，修改“某机型配置文件”

1. (可选) 修改机型配置文件
   
2. nano /opt/rt-n56u/trunk/configs/templates/PSG1218.config

复制代码

路径就是

1. /opt/rt-n56u/trunk/configs/templates/

复制代码

随便找了一个<k2p>的打开，其中有如下代码，你应该懂了

1. # CONFIG_RT2880_DRAM_16M is not set
   
2. # CONFIG_RT2880_DRAM_32M is not set
   
3. # CONFIG_RT2880_DRAM_64M is not set
   
4. CONFIG_RT2880_DRAM_128M=y
   
5. # CONFIG_RT2880_DRAM_256M is not set
   
6. # CONFIG_RT2880_DRAM_512M is not set

复制代码

对了，你要仔细看完整个代码，上面片段只是RAM，不是FLASH大小。

...

谢谢，我试试看吧。

看了RuiBox的回复，就去找了PSG1218.config，发现不是这个文件里修改设置。应该是在/opt/rt-n56u/trunk/configs/boards/PSG1218/kernel-3.4.x.config这个文件中修改。

flash能自适应？

FLASH能自适应  不过空间没法全部用

如果要USB驱动，那么改哪里？
