您好,
1.重启之后是否还会卡在下图位置?


如果不卡,能重新进入系统,那么卡住的概率有多高?
2.如果还是卡在那里,在Ubuntu下将SD启动卡的dra7-dsp2-fw.xe66固件删除
a.删除后能启动,排查是否为DSP2固件问题

b。删除后不能启动,排查是否为DSP2固件问题
3.您使用的DSP2固件是有做过什么修改还是?

1、这次重启起来了。
2、我做的操作有:
   编译server_dsp1.xe66和server_dsp2.xe66,上传到板子上,
   然后load-firmware.sh
   然后执行arm程序

当arm上MessageQ_create始终都失败之后,就reboot板子。

没做过其他操作。

你好,
        1. 从附件的打印信息来看,多次启动失败都停在了DSP2固件加载启动的过程中。
        2. 乱码打印的错误信息来看,DSP2中设计到了内存错误访问的情况。

调试建议:
        1. 可先确认是否为DSP2所导致的启动问题,若原本失败的概率较高;则可通过删除DSP2固件的方式来排除是否为DSP2的问题。
        2. DSP2的启动失败比较大可能是因为内存问题,可确认内存映射表以及代码中,对物理虚拟地址的访问部分,确认问题的根源。
