MsiEcRamEditor

Alternative Linux method

On Linux, you can directly monitor EC RAM using this command instead:

sudo watch -n 0.1 hexdump -C /sys/kernel/debug/ec/ec0/io

If the path is unavailable, install an kernel module like: https://github.com/musikid/acpi_ec (and substitute path with /dev/ec if required).

To write to memory, I used ISW-Modern on Linux:

sudo isw -s <addr> <value>
