  1. A display connected to the DSI connector of Raspberry Pi 5 does not work when using Armbian. However, the display works perfectly when using the Raspberry OS. My OS image is: Armbian_25.2.2_Rpi4b_bookworm_current_6.12.15_cinnamon_desktop Dmesg reveals the following information: [ 13.283052] mipi-dsi 1f00118000.dsi.0: deferred probe pending: mipi-dsi: supplier 2.reg_bridge not ready [ 13.283060] platform 1.panel_disp: deferred probe pending: platform: wait for supplier /axi/pcie@120000/rp1/i2c@88000/reg_display@45 This forum post suggests, that the problem is due to the missing I2C driver "CONFIG_I2C_DESIGNWARE_PLATFORM": https://forums.raspberrypi.com/viewtopic.php?t=375851 And indeed, on the working Raspberry OS image, i find the following files in the directory /lib/modules/.../kernel/drivers/i2c/busses: - i2c-designware-core.ko.xz - i2c-designware-platform.ko.xz These files are not present on the Armbian image, I assume that these are the missing drivers. Could someone please add the drivers to the build configuration, so that DSI displays will work in the future on RPi5? https://paste.armbian.com/owihivazuc
