解决：问题找到了，tina linux内核rootfs只支持squashfs文件系统，如果选用其它文件系统就会出现上面的情况

如题，在使用T113-i的DSP做定时器类测试时，希望可以产生一个周期中断，在中断中完成定时任务，但是手册中对于DSP中断的应用讲解的非常少，不知道有没有人了解可以给讲讲，或者给个资料也可以啊。

@maihuanyi 没有解决，希望有高手出面解决

问题有新的进展了，因为boot分区时fat格式的，我将boot分区挂载到root分区的目录下，然后通过sftp将文件传送到boot分区中，传送成功了，系统并没有死机。似乎这个文件复制过程死机和ext4文件系统有关系。原来传输的文件大小为5k左右，我把文件调大到10k，传输同样会失败。我现在也不清楚时文件系统格式的问题还是文件大小的问题，有没有大神可以出来指导一下。

@story_xjj
我还发现了一个怪现象，因为创建的SD卡镜像中，boot分区时fat格式的，如果用读卡器把文件复制到boot分区中，然后重新引导系统，挂载boot分区，再把文件复制到或移动到根分区中，就不会出现死机的情况。一切正常。
而且编译的文件可以正确执行。

[root@buildroot ~]# ls

根据网上的buildroot创建了一个D1s的镜像，启动和运行都是比较正常的，由于东山派D1s没有网络接口，所以我利用RNDIS虚拟了一个网络，SSH可以正常登录，执行命令和查看修改系统的信息没有任何问题。在通过SFTP方式上传是出现了死机的情况，于是采用nfs链接windows的nfs服务器，可以正确链接，向windows的nfs服务器创建文件没有任何问题，但是向linux系统拷贝文件同样会出现死机的情况。

下面是系统打印的日志，请各位看看是什么原因导致的。

非常好的内容，正需要

解决：问题找到了，tina linux内核rootfs只支持squashfs文件系统，如果选用其它文件系统就会出现上面的情况

针对d1s，调整了rootfs分区的大小为204800后，重新编译生成的img文件达到了58M左右。烧录后启动提示root分区无法打开。
启动信息记录如下：

屏幕有显示，但是屏幕闪烁，并且图片内容有重影。
在终端执行disp命令的显示信息如下：
