im8mq-evk 支持jailhouse虚拟机,但是在实际测试中,gic测试和uio_ivshmem测试都很正常;测试linux时候,总是报:

因为我的板子只有一个mmc,dts中标记为usdhc1,使用fsl-imx8mq-evk-root.dts的时候,打开了usdhc1,而在fsl-imx8mq-evk-inmate.dts上禁用了usdhc1(也就是删除了这个节点),上述打印依然会出现

请问,使用jailhouse 是否必须配备两个mmc设备(或者emmc+sdcard)?是否可以共用板载emmc?

希望有人能提供答案或建议~

If you are destroying inmate linux and restart it again, I suspect it might be sdhc controller not been reset when you recreate inmate linux. There should be fix in i.MX latest BSP. which release are u using, what test are you doing?
