I also appreciate LZ4's simplicity and tiny code footprint.

zstd is brilliant as well, but in terms of code base it's a whole other beast.

Yes decompression on baremetal cortex m4 is a mere hundreds of bytes, you can decompress it from flash directly to its output buffer.

I've used it in bootloaders that have slow transfer mechanisms (uart, i2c) to get whatever speedup I can for a few hundred bytes of binary.
