为什么会出现下面显示：

:em12: 麻烦大家啊，我这里地址该怎么设置啊

tangpujun

我ramdisk大小是29316K,而zImage 为1940K

若我不写入flash，写到ram中，则显示如下信息：

kernel编译的有问题？

tangpujun

不是编译有问题，我那是专门网站下的针对该开发板的内核

bamv2005

是不是串口或波特率问题?
1, 如果"booting the kernel"后面就没东西了可能是串口选的不会. 内核自解压时是直接写的uart寄存器, 所以能显示.
2, 如果"booting the kernel"后面都是乱码, 怀疑是PC机串口终端波特率不正确, 如果bootloader串口波特率比内核串口波特率低, 就会出现乱码. 如果是波特率问题, 内核启动完乱码就不出了, 这是回车应该还是出乱码. 可以在内核启动时把波特率改大些, 57600, 115200等.
