Hey everyone,
Long time admirer, first time poster :)
I have just flashed an x200 with libre and t440p last night with core as a first step into the community (with many more to come!).
I have contacted both the t440p fork repo as well as the gentleman running the 0xcb website to alter their directions, however at this time they seem unresponsive.
yk, I did the following to get it working:
- backup stock bios and store - clone upstream coreboot (NOT the t440p fork) - build ifdtool and export the blobs (ifd.bin, me.bin, gbe.bin), put them somewhere accessible - obtain the mrc.bin as per instructions on the coreboot website, place that mrc.bin in the root dir of cloned repo - used the .config file from this tutorial: https://0xcb.dev/lenovo-t440p-coreboot/ and changed the filepaths to match location of ifd.bin, me.bin, and gbe.bin (afaik absolute filepaths must be used) - ran make nconfig: double check all values that .config was read properly, select Chipset and select "Add a System Agent Binary" make sure underneath it says "(mrc.bin) Intel System Agent path and filename", in the Chipset submenu go down to where it says "Add Intel descriptor.bin" and change that to wherever you put the ifd.bin. - build the compiler toolchain - build coreboot - split the images according to 0xcb's tutorial - flash each image to respective flash chips
I hope this helps and brings you a successful boot! :)
