I made a Lisa/M 2.1 board with Asprini 2.2 myself. when I upload firmware I found there is no Asprini 2.2 driver available. So I select the airframe configuration option like this:<target name="ap" board="lisa_m_2.1"/>. After upload I can't initialise it,also can't read the sensor data.
How long can we have a stable driver for Asprini 2.2
Thank you !
