The PineNote is a 10.3" e-ink tablet produced by Pine64 for the Linux mobile community.

Installation

Note This will erase your userdata and make android unbootable, take backups of all affected partitions via ADB (rkdeveloptool read-partition only allows reading partitions < 32mb)

Currently, installing postmarketOS requires UART access to manually boot the mainline kernel. If you have a developer unit, removing the back cover will reveal the pre-soldered UART wires, if you have a production unit you will have to solder these yourself. This will be resolved as soon as we have a u-boot build which can auto-boot from extlinux.

Install rkdeveloptool from https://gitlab.com/pine64-org/quartz-bsp/rkdeveloptool, put the end of the pen near the top right of the back of the device to trigger rockusb mode.

We need to wipe the boot and recovery partitions to make sure u-boot doesn't try and boot Android

fallocate 32M blank.bin
rkdeveloptool write-partition boot blank.bin
rkdeveloptool write-partition recovery blank.bin

Now build an image with pmbootstrap, I would recommend Phosh or sway.

pmbootstrap init # pine64 pinenote
pmbootstrap install

And flash (pmbootstrap supports rkdeveloptool as of pmbootstrap!2165).

pmbootstrap flasher flash_rootfs # flashes to userdata
pmbootstrap flasher flash_kernel # flashes to cache

Alright, now for UART, reboot the device and it should put you in a u-boot shell, we can boot with:

$ picocom /dev/ttyUSB0 -b 1500000 -l

=> sysboot ${devtype} ${devnum}:b any ${scriptaddr} extlinux.conf

b is the partition number (decimal 11 encoded in hex) for the cache partition, where we flashed the extlinux boot partition to.

You should now see the postmarketOS splash and the pinenote will boot.

How to enter flash mode

The device is only flashable using the rkusb bootloader mode. This can be done with the opensource rkdeveloptool utility.

To trigger the bootloader hold a magnet on the backcover of the pinenote while powering it on.

When it's booted correctly into bootloader mode it should show up in the device list of rkdeveloptool:

$ rkdeveloptool ld
DevNo=1 Vid=0x2207,Pid=0x350a,LocationID=100    Loader

It's possible to overwrite the eMMC with the LBA write command:

$ rkdeveloptool wl 0 rootfs.img
The 0 is the offset in blocks from the start of the eMMC, can be used to flash a partition if you know the offset

Recover from a broken bootloader

If uboot image is overwritten the rockusb mode won't work anymore. The device might boot into maskrom mode in which case it should show up in `rkdeveloptool list` as maskrom. If the uboot image is partially overwritten but still recognized by the maskrom it won't stay in maskrom mode and you'd have to open the back of the device and short TP1301 and TP1302 while powering up. This will make eMMC reads fail so maskrom always runs.

Once the device is in maskrom mode the only thing you can do is push a new loader into ram and start that.

$ rkdeveloptool list
here it lists maskrom now

The .bin file is build by u-boot and might have a slightly different version
$ rkdeveloptool db rk356x_spl_loader_v1.04.108.bin
$ rkdeveloptool ptt
now it's able to read flash and list the partitions
