SDK-A13 # A13-based devices (626, 627, 641, 840)
SDK-B288 # B288-based (632, 740)
SDK-iMX6 # 631
(thanks)

PocketBook Touch HD3 has codename 632.
PocketBook InkPad 3 Pro has codename 740-2 IIRC, same SoC as 740.
B288 is sun8iw10 by manufacturer Allwinner.

cat /proc/version to get the cross compiler, e.g. Linux version 3.10.65 (jenkins@bsp-builder) (gcc version 4.9.2 20140904 (prerelease) (crosstool-NG linaro-1.13.1-4.9-2014.09 - Linaro GCC 4.9-2014.09) ) #2 SMP Fri Mar 29 11:59:01 EET 2019. See /proc/config.gz for kernel compilation env

In each of the SDK_6.3.0/SDK-* directories, there's a config.cmake file with flags, dunno if it's what you need?
SET (GENERAL_FLAGS "-mcpu=cortex-a8 -march=armv7-a -mfpu=neon -mfloat-abi=softfp")

It targets an ARMv7 ISA with soft floating point and uses the GNU EABI (Linux, not the bare metal ARM one), therefore a lot of compiled binaries work out of the box.

The reader app for epub and PDF relies on closed-source ReaderLib (libpbrdlib.so). It is cross-compiled using clang and uses libraries such as Qt, SQLite 3, DjVu and probably others. This dynamic module relies on libadobe_rmsdk.so for DRM and libinkview.so for interacting with the device (for IPC, etc.).
AFAICT, it is a custom-made renderer and sadly cannot be patched for QML stylesheet rules like Kobo eReader (or provide a better alternative).

OTOH, eink-reader.app which is the main GUI relies heavily on Qt and should be customizable with enough research.
e.g. binwalk --dd='gzip:gz:gunzip %e' -C _outdir ebrmain-cramfs/bin/eink-reader.app

see https://github.com/dennwc/inkview for a Go implementation of SDK, it may help with porting stuff in pure Rust
