If you have some time to spend on getting your video driver working right, consider adding <code>printk</code> statements in your kernel to understand what it does and where it fails. After building your kernel and flashing, check <code>dmesg</code> for your debug output. See [https://gitlab.com/postmarketOS/pmbootstrap/issues/1618#note_88908569 #1618 (comment)] for a detailed example.
