Hi Renuka<br><br><div>If I'm not mistaken this warning refers to a missing firmware descriptor binary. This file will be present in the ROM that was flashed to the chip before you received the board.<br></div><div style="font-family: Arial, sans-serif; font-size: 14px; color: rgb(0, 0, 0);"><br></div><div>If you don't know how to get that file, do the following:</div><div>You'll need to use the ifd tool (<code>cd coreboot/util/ifdtool</code>​) to extract it from the factory firmware that's currently on your mainboard. Copy your backup firmware.rom to the ifdtool folder to make it easier, and run <code>./ifdtool -x firmware.rom</code>​<br></div><div>It will also extract other files too, like the management engine binary and BIOS region.<br></div><br><div>In the menuconfig interface, go to -&gt; chipset and scroll down to "add Intel descriptor.bin file".&nbsp; Select this and enter the path to the descriptor binary you just extracted.<br></div><div><br></div><div>You'll also see an entry for Management Engine which you'll need to include as well in order to get a usable image. Again, select this entry and provide a path to the Management Engine file.</div><div><br></div><div>I recently built for a tigerlake Chromebook and this process is exactly what worked for me. <br></div><div style="font-family: Arial, sans-serif; font-size: 14px; color: rgb(0, 0, 0);"><br></div><div>If you want to know more about what the purpose of the Flash Descriptor, check out this <a href="https://doc.coreboot.org/util/ifdtool/layout.html" title="coreboot doc">coreboot doc</a>. As I understand it, the Descriptor region is configuration data similar to a partition table for your SPI chip.<br></div><div style="font-family: Arial, sans-serif; font-size: 14px; color: rgb(0, 0, 0);"><br></div><div>Hopefully this helps you get to the next stage, and apologies if I went over things you already knew.<br></div><div><br></div>-------- Original Message --------<br>On 22 Feb 2023, 20:41, Renuka Pande &lt; rrmr6093@gmail.com&gt; wrote:<blockquote class="protonmail_quote"><br><div dir="ltr">Hi,<div>I am trying to configure coreboot and fsp for Intel Tigerlake Board.</div><div>I am facing the following issues:</div><div><br></div><div>While building coreboot, in the menuconfig command, in mainboard section, if the ON BOARD EC is selected as INTEL EC, when make command is given, it is giving "Makefile:215" error. </div><div>If the ON BOARD EC is selected as Chrome EC, then only the make is successful.
