zero spi flash启动时卡在了Starting kernel ...,大神们帮我看下

参考官方文档做flash:http://zero.lichee.pro/%E7%B3%BB%E7%BB%9F%E5%BC%80%E5%8F%91/SPI_flash_build.html#

启动时卡在了Starting kernel ,没有任何下文,等多久都没有用

可以考虑进入uboot命令模式,看下bootcmd和bootargs这两个参数。
print bootcmd
print bootargs
或者printenv

不知道了,匿了...

可以看下烧录的zImage文件有多大,荔枝派是给内核分配了4M空间。

Re: zero spi flash启动时卡在了Starting kernel ...,大神们帮我看下

boot 前可以用 crc命令计算出文件(内存段)的校验码,和写入文件的校验码比较,如果对不上, 那就是zImage或者dtb有问题了.

编译后是4.1M,也有4M,都试过了,也不行

超过4M应该是不行的,可以试试将文件系统再裁剪下。

uboot和kernel用的不是同一个console 也是这种现象

好像是SEC_4K的问题,我没去搞了,卡在alsa编译的问题上
