Hello,

I’m trying to port the FreeRTOS cell for Jailhouse to x86\_64 environment.  
（[https://github.com/siemens/freertos-cell）](https://github.com/siemens/freertos-cell%EF%BC%89)  
Currently it can only be run on ARM systems.

Can anyone give me suggestion for what should be considered to achieve this goal?

As the document has mentioned, I should modify the serial interface access for x86 to construct a correct memory map, probably by creating a new file like this  
([https://github.com/siemens/freertos-cell/blob/master/jailhouse-configs/bananapi.c](https://github.com/siemens/freertos-cell/blob/master/jailhouse-configs/bananapi.c)) for x86.

But what more should be done?

Best regards,

Sean

Don’t know much about Jailhouse, but if you are using FreeRTOS on a 64-bit part then ensure you are using the latest FreeRTOS version as some changes were made to run on the Cortex-A53 in 64-bit mode.
