<div><font face="Calibri" size="2"><span style="font-size:11pt;"> </span></font></div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;">How to build this image => <b>obmc-phosphor-image.rootfs.wic.qcow2</b> ? In openBmc build directory we don’t get this image built. </span></font></div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;"> </span></font></div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;">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 . </span></font></div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;"> </span></font></div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;">Please advise if we have to build openbmc stack in a different way than the standard procedure. We follow the below steps for build, </span></font></div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;">1. . setup Romulus</span></font></div>
<div><font face="Calibri" size="2"><span style="font-size:11pt;">2. bitbake obmc-phosphor-image</span></font></div>
