Following up on the source candidate for the Samsung HW-Q800A (archive: 19_SoundBar_HW-Q800_850A.zip), here’s a summary of my analysis and results.


Build Process (BusyBox 1.22.1)

I unpacked the archive and focused on busybox-1.22.1.tar.bz2 due to its central role in embedded Linux environments.
Steps:
1. Extracted:
mkdir /root/busybox-src
tar -xjf busybox-1.22.1.tar.bz2 -C /root/busybox-src --strip-components=1
2. Installed dependencies:
apt update
apt install -y bzip2 build-essential libtirpc-dev libncurses-dev
3. Built BusyBox:
make defconfig
make -j4
Build Issues & Fixes:
- Missing rpc.h → installed libtirpc-dev
- Undefined 'stime' in rdate.c → disabled ‘rdate’ and ‘date’ via make menuconfig
- Missing curses.h → installed libncurses-dev
Result: Successfully compiled a statically linked ARM64 binary and entered a working BusyBox shell using chroot.


Candidate Completeness

The archive included many source packages but lacked top-level build scripts, integration instructions, or flashing tools. Other components were inconsistently packaged (.rar, .tgz) with little documentation. No scripts for full firmware assembly or installation were provided.
