Integrating swtpm(as a software TPM) with OpenBMC on Qemu

Hi C,

How to build this image =>  obmc-phosphor-image.rootfs.wic.qcow2 ? In openBmc build directory we don’t get this image built.

Also, remaining image formats used while running on qemu are available in the build directory. i.e fitImage-linux.bin, aspeed-bmc-ibm-rainier.dtb and obmc-phosphor-initramfs.rootfs.cpio.xz .

Please advise if we have to build openbmc stack in a different way than the standard procedure. We follow the below steps for build,
1. . setup Romulus
2. bitbake obmc-phosphor-image

Thanks,
Sandeep.

Hi C,

Got it working. Looks like slirp is no longer supported on ubnutu 18.04. have upgraded to a newer version  and is working now.

Thanks,
Sandeep.

Did you install the libslirp-dev or libslirp-devel package ?
