How to use eSPI between Host and slave BMC in openbmc project

[zhang_cy1989]

Dear Kwin
    I'm very sorry for the late reply.
    I'll try it later. Maybe delayed some days for other things.
    Anyway, the result and any problem will be show here after my experiment.
    Looking forward to more communication with you
    Thanks

Felix

Hi  Felix,

 

Both KCS and eSPI driver are ready x86 platforms.

Please refer https://github.com/Intel-BMC/

 

Example:

https://github.com/Intel-BMC/openbmc/blob/intel/meta-openbmc-mods/meta-ast2500/recipes-bsp/u-boot/files/0022-KCS-driver-support-in-uBoot.patch

https://github.com/Intel-BMC/openbmc/blob/intel/meta-openbmc-mods/meta-ast2600/recipes-bsp/u-boot/files/0005-Ast2600-Enable-interrupt-in-u-boot.patch

https://github.com/Intel-BMC/openbmc/blob/intel/meta-openbmc-mods/meta-common/recipes-kernel/linux/linux-aspeed/0022-Add-AST2500-eSPI-driver.patch

 

 

BTW: you could set Acute travel logic to analyze eSPI bus. There is eSPI connector on Intel CRB platform.

 

Thanks,

Kwin.

 

 

 

Dear James/andrew/Oskar
    Thanks a lot.
    I am studying eSPI spec. But it's hard to find any products with eSPI.
    Your reply gives more understanding about eSPI.
    
    Looking forward to more applications with eSPI in openbmc project.
    Thanks again.

Felix
