I had a whitescreen but no obvious errors when using 'sudo vcdbg log msg' or 'dmesg'. Both /dev/fb0 and /dev/fb1 were present. Followed this article on waveshare32b that 'reset_gpios needed to be 0 0 1 instead of 0 0 0' (https://forum.armbian.com/topic/13233-any-clues-for-the-creation-of-a-dtoverlay-for-fbtft-on-54y/). I applied a similar change to this dts file and compiled a new dtbo: 'dtc -O dtb -o hy28b.dtbo hy28b-overlay.dts'. Fixed my issue - may help others? I got from the 5.4 upgrade thread that other tft users are having issues with small tfts... https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=269769&p=1706597&hilit=gpio#p1706597 ---- - arch/arm/boot/dts/overlays/hy28b-overlay.dts | 2 +- - 1 file changed, 1 insertion(+), 1 deletion(-) - ---- a/arch/arm/boot/dts/overlays/hy28b-overlay.dts -+++ b/arch/arm/boot/dts/overlays/hy28b-overlay.dts -@@ -61,7 +61,7 @@ - fps = <50>; - buswidth = <8>; - startbyte = <0x70>; -- reset-gpios = <&gpio 25 0>; -+ reset-gpios = <&gpio 25 1>; - led-gpios = <&gpio 18 1>; - - gamma = "04 1F 4 7 7 0 7 7 6 0\n0F 00 1 7 4 0 0 0 6 7"; |
