各位帮我看一下。

我的SPI flash启动不起来,不知道为什么。。。。
[    0.819749] m25p80 spi0.0: mx25l12805d (16384 Kbytes)
[    0.824837] spi0.0: parser cmdlinepart: 0
[    0.828928] spi0.0: parser ofpart: 0
以上是Log信息。也确认命令行内容是没有问题的。
却解析不出分区信息来。不知道为什么。

正常识别到分区,应该报以下信息:

找个正常的固件, 从 u-boot, dtb, zImage, jffs2文件系统, 一个一个替换排除问题了。

Re: 各位帮我看一下。

我重新下了4.13.版的源代码来编译,终于可以识别到分区了。可是不能正确引导。。。。。吐血。。。。前面的问题,经过对比,发现是dts的问题。

Re: 各位帮我看一下。

jffs2文件系统挂载成功,但是几个可执行文件都执行失败,看下是不是文件系统做得有问题,或者文件没有可执行属性,或者缺库
