How to use thinkpad-ec on Nitropad bios

Nitrokey Generic
#1

Hi,

I am trying to do this GitHub - hamishcoleman/thinkpad-ec: Infrastructure for examining and patching Thinkpad embedded controller firmware to enable usage for t420 keyboard change for my t430.

I have CBET4000 Heads-v1.4-6-gd46488a
but thinkpad-ec github page says i need BIOS 2.81 (G1ETC1WW) and EC 1.13 (G1HT35WW)

Does that mean there is no way for me to ec flash it unless I’m willing to go back to G1ETC1WW?

#2

says here it can be ec flashed on G1ETC1WW and then possible to upgrade to coreboot

#3

Yes, it is not possible with our firmware. You would need to flash back the old bios.

To be more precise: This might be possible under coreboot/heads, but it would need quit a deep dive which unfortunately nobody seems to has done till now
