Hi Justin,
Ensure the GPIO’s for the south bridge you are looking for kaby lake 7280 are available in coreboot\util\inteltool\gpio.c
CM238 is a skylake chipset -> https://en.wikipedia.org/wiki/List_of_Intel_chipsets
Have you tried inteltool -g -G?
Regards Ranga

As the subject states, whenever I run inteltool -a under root, I do not get any outputs. My dump is listed below. I am running a kaby lake 7820hq for reference. Any help would be appreciated. Is kaby lake not supported for coreboot? Best, ~Justin
