Would it help if I include logs here? If so, which logs?
ectool will also show some timers, which are counting upwards in the dump. Last time I've looked at the ECDT (x201) it doesn't contain any additional information. There are multiple ways to provide the information saved in the ECDT. Coreboot is using the DSDT for that.
Let's say you know which byte is changing in the EC ram, what would you do than?
Best, lynxis
Here is the diff (from factory BIOS):

Here is the diff from coreboot (on another X200, though, so probably different EC version):

Also on this dump, 0xc1 and 0xca change.
I'm not currently sure what to make of this.
