Christopher Collins updated MYNEWT-790: --------------------------------------- Description: (Pull request: https://github.com/apache/incubator-mynewt-newt/pull/74) PKG-A can only override a setting defined by PKG-B if PKG-A has a greater priority than PKG-B. If PKG-A's priority is less than or equal to PKG-B's, the override attempt is rejected and reported as a priority violation. This commit relaxes that rule slightly: a package can override settings that it itself defines. This behavior is needed for making a setting's default value conditional on another setting. For example: {noformat} syscfg.defs: TIMER_0: description: 'NRF52 Timer 0' value: 1 TIMER_3: description: 'NRF52 Timer 3' value: 0 # Use timer 3 instead of timer 0 if target wants to use the low # power clock. syscfg.vals.BLE_LP_CLOCK: TIMER_0: 0 TIMER_3: 1 {noformat} was: (Pull request: https://github.com/apache/incubator-mynewt-newt/pull/74) PKG-A can only override a setting defined by PKG-B if PKG-A has a greater priority than PKG-B.
