Successfully built and booted postmarketOS on Samsung Galaxy J4.
It's based on Exynos 7570, same SoC used by samsung-xcover4lte [1].
Currently, these are tested working:
- Boots from internal storage
- Display (console framebuffer is NOT working, kernel panics)
- Framebuffer (additionally with msm-fb-refresher to refresh the screen)
- Touchscreen
- USB Networking (RNDIS)
- Wi-Fi
Tested UI environments:
- XFCE 4
- Console (Kernel log doesn't show up because
`CONFIG_FRAMEBUFFER_CONSOLE` is not enabled, but enabling it panics
the kernel. This is a known issue for some Samsung devices, notably
samsung-crownlte [2].)
