For example, on a Pi2 the command emits MK_WIRELESS = yes MK_WIRELESS_SUPPORT = yes Given that there's no onboard wireless and no USB WiFi adapter, it's fairly obvious those two can be set to "no". It's less clear what MK_TEXTPROC = yes portends, and whether it's essential. Perhaps I mis-posed the original question. What I'm looking for might better be called a minimal kernel configuration supporting only the hardware native to a particular board. The old RPI2 kernel config file seemed to do that, but I gather it's deprecated. Thanks for reading! bob prohaska
