Hello
I just get a new hyperpixel4 to play and have an issue as it display only line (changing lines but only lines)
I have tried following https://learn.pimoroni.com/tutorial/sandyj/getting-started-with-hyperpixel-4
with 2 fresh sdcard (SAN Disk ExtremPlus) with 2018-11-13-raspbian-stretch-full.img on 2 Pi 3 b+ to insert the new HAT
/boot/config.txt get
dtoverlay=hyperpixel4
overscan_left=0
overscan_right=0
overscan_top=0
overscan_bottom=0
framebuffer_width=800
framebuffer_height=480
enable_dpi_lcd=1
display_default_lcd=1
dpi_group=2
dpi_mode=87
dpi_output_format=0x7f216
display_rotate=1
hdmi_timings=480 0 10 16 59 800 0 15 113 15 0 0 0 60 0 32000000 6
$ ls -lart /boot/overlays/hyperpixel4.dtbo
-rwxr-xr-x 1 root root 1855 déc 1 22:14 /boot/overlays/hyperpixel4.dtbo
I use the official rapsberry 2A micro USB power
Is there a trick or should I consider that the HAT is defective ?
