hi,<br>  as what you mentioned yesterday, i tried to make to use Makefile to load the libpayload kconfig instead of using <br>&quot;source&quot; command.<br>I can successfully load libpayload&#39;s config by modifying some code of the /util/kconfig/Makefile<br>
but the only problem left now is that i can not make them saved in separate files.<br>There is a env variable &quot;KCONFIG_CONFIG&quot; which is used to indicate the file to save the configuration.<br>i can make it work in the main frame of Makefile by <br>
&quot;export KCONFIG_CONFIG=lib.config&quot;<br>but it can not work while i put this command under the rules. which looks like<br><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">
memuconfig:<br>      $(Q)export KCONFIG_CONFIG=.config<br></blockquote><div><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">libpayload:<br>      $(Q)export KCONFIG_CONFIG=lib.config<br>
</blockquote> <br></div>  in this case i can not change this variable. Is there any suggestion about this?<br>i cc this mail to the coreboot list, there may some one known this problem.<br>
