Hi,

This is just a suggestion/feature request, but it would be really useful to have this sort of feature in a FW laptop.
We have this sort of feature, Closed Case Debug (CCD), to reach the EC console. Having similar to reach the JTAG of the CPU, BIOS firmware, PD firmware etc. would be excellent.

To help us know if the link is likely to be of interest, it would help if you could quickly summarise what JTAG is and how would it benefit users.
