mmc报错

有没有人碰到过，板子运行过程当中报mmc2的内核错误？

djh 发表于 2021-9-26 13:35:53

用的是出厂镜像吗？有具体的报错信息吗？

您用的是8MM吗？
是每次跑应用程序都会报错吗？
应用程序做了哪些操作啊？

lp1982sdu 发表于 2021-9-27 17:42:32

是的。我尝试在上面跑了jailhouse,那个嵌入式的虚拟机静态分区工具。100%会报这个错。上面还有一点信息。

psci: CPU2 killed.

jailhouse 大概会分配CPU MM 虚拟一些pci 设备，映射些中断，这些操作。

这个不清楚原因，您在网上找找看有其他人遇到过没。可以看看应用程序的实现逻辑
