Might there be a good reason that ectool doesn’t work on the new AMD Ryzen based Framework laptops yet? I get “Unable to establish host communication” for every --interface option I try.
I received mine just a couple days ago, I’ve installed firmware (bios) 3.03, and I’m running Arch linux with kernel 6.5.9, and have installed “fw-ectool” from aur, the build script basically just clones the latest from Dhowett/framework-ec and does make utils.
By default, the modules cros_ec and cros_ec_lpcs are loaded. I’ve tried modprobing a bunch more, including cros_ec_sysfs, cros_ec_dev, cros_ec_chardev, and cros_ec_i2c, they load but do nothing. Secure boot is off, lockdown is “[none]”. I’m flailing at this point (more generously, looking for a quick and easy clue about what key piece I’m missing).
$ sudo fw-ectool version
Missing Chromium EC memory map.
Unable to establish host communication
Couldn't find EC
$ sudo fw-ectool --interface=lpc version
Missing Chromium EC memory map.
Unable to establish host communication
Couldn't find EC
...
Sure seems like default or lpc should work. Any hints? Laptop too new?
EDIT: found a hint in dmesg:
[ 2.950398] cros_ec_lpcs cros_ec_lpcs.0: EC ID not detected
