HW-Q800A

[Hogenkamp, William J]

Hi all,
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.

Best,
Liam Hogenkamp
