Hi Mauro,<br /><br />I assume that you are working with poky/meta layer.<br />You can use conditional function from oe.utils library like this:<br /><br />YOUR_VAR = "${@oe.utils.conditional("VAR_NAME", "compare_value", "value_if_true", "value_if_false", d)}"<br /><br />myrecipe.bbappend:<br />FILE_NAME = "${@oe.utils.conditional("MY_VAR", "white", "white.txt", "default.txt", d)}"<br />do_install_append() {<br />&nbsp;&nbsp;&nbsp; install -m 0644 ${FILE_NAME} ${D}/etc/value<br />}<br /><br />local.conf:<br />MY_VAR = "white"<br /><br />Another way is using in-line python conditional statement:<br />FILE_NAME = "${@'white.txt' if 'white' in d.getVar('MY_VAR') else 'default.txt'}"<br /><br /><br />If you want more than two values, consider using variable flag:<br /><a href="https://www.yoctoproject.org/docs/latest/bitbake-user-manual/bitbake-user-manual.html#variable-flag-syntax" target="_blank" rel="noopener">https://www.yoctoproject.org/docs/latest/bitbake-user-manual/bitbake-user-manual.html#variable-flag-syntax</a><br /><br />Regards,<br />DD
