dacen 0 Posted September 5, 2019 Share Posted September 5, 2019 My board is rockpi4b After starting, unplug or restart the display, the display will display armbian desktop directly, indicating that armbian is started normally, but there is no normal signal to the display.After restarting, you must switch the monitor power or unplug the hdmi cable to display. This is not a problem if you use the official debian of rock and the armbian5.67 downloaded from rock's official website. And i want to use gpio lib in armbian such as libmraa ,how should i do? 0 Quote Link to post Share on other sites

Igor 2110 Posted September 6, 2019 Share Posted September 6, 2019 Well, we don't want to maintain yet another RK3399 source ... some investigation and cherry picking from https://github.com/radxa/kernel/commits/release-4.4-rockpi4 might perhaps solve this issue. 0 Quote Link to post Share on other sites
