After recently upgrading to 2.8 we are having troubles getting configuration fragments applied to the kernel.
We have a .bbappend file that adds a few patches and configuration fragments to the kernel build. The patches are being applied correctly, but the kernel configuration fragments do not seem to make it into the work/colibri_imx7…/linux-toradex/4.9…/build/.config file. The config fragments (.cfg files) are being copied into the build directory, however.
Is there something we’re missing? This used to work fine in 2.7.
The SRC_URI includes the statement “file://sc16is7xx.cfg”. While the fragment file (generated by doing a menuconfig, then diffconfig) contains these statements:
CONFIG_SERIAL_SC16IS7XX_CORE=y CONFIG_SERIAL_SC16IS7XX=y # CONFIG_SERIAL_SC16IS7XX_I2C is not set CONFIG_SERIAL_SC16IS7XX_SPI=y
