Usage:
follow the instructions here to uncompress the image and flash the resulting .img file to an SD card, put it into your Bela and boot the board. Sorted!

If you have trouble booting the new image on the BeagleBone Black, check out this.

Highlights:

• Debian 11 Bullseye
• to flash to emmc, you need to replace /opt/Bela/bela_flash_emmc.sh with this https://github.com/BelaPlatform/bela-image-builder/blob/bullseye-2022/misc/rootfs/opt/Bela/bela_flash_emmc.sh (make sure you do not change execution permissions)
• Supercollider needs manual install of attached .deb package
• running Pd will give you a stream of [Xenomai] bad syscall <0x197> in dmesg. This seems to be triggered by what's running within sys_doio(), but it's unclear what it is. This may be because the libc present here expects a different kernel from the one in use: bits/syscalls.h expects kernel 5.5. So if you want to use Pd here please refrain from using network/disk I/O and uncomment #define PD_THREADED_IO in core/default_libpd_render.cpp or accept a performance penalty due to the excessive logging. If your I/O timing is not critical, try changing usleep(3000) in fdLoop() for something larger.
• longer build times with clang-11
