This tool patches the firmware with 4K support and applies the register changes also found in hsdaoh.
You can use ms-tools to flash the firmware. Make sure to backup your firmware:
./cli --log-level=7 read FLASH 0 --filename=backup.bin
and then flash the new firmware with:
./cli --log-level=7 --no-patch write-file FLASH 0 ms2130_patched_v1.bin
