It is possible to set up a partition for mainline development without disturbing the factory Android installation. This allows updating a mainline kernel, DTB, and initramfs over Wi-Fi until WiFi or USB OTG is working in mainline Linux. | It is possible to set up a partition for mainline development without disturbing the factory Android installation.

The recommended partition for this is <tt>mmcblk0p11</tt> aka <tt>/cache</tt>. It is large and already formatted as <tt>ext4</tt>, so it is readable from U-Boot.

It is possible to shrink the <tt>userdata</tt> partition, and create a new partition at the end for use with mainline Linux. This provides much more space than <tt>cache</tt>. However, because <tt>userdata</tt> is formatted with <tt>f2fs</tt>, and that filesystem cannot be shrunk, resizing the partition requires wiping <tt>userdata</tt>. | |||
# Back up any necessary files from userdata | |||
# Boot to a mainline kernel from <tt>mmcblk0p11</tt>, either using that partition as rootfs (see above), or using an initramfs with repartitioning tools | |||
# Modify the partition table with your favorite tool, e.g. <tt>fdisk</tt>, <tt>gdisk</tt>, or <tt>parted</tt> | |||
# Reboot into <tt>fastboot</tt> and wipe <tt>userdata</tt>. | |||
# Reboot into Android, where you can now chroot in and install your favorite distribution to the new partition. | |||
