The descriptor provided with the FSP does not seem to work. Update the instructions to use the descriptor from the original Intel firmware.

-You still need two more binary blobs. These come from the sample SPI image -provided in the FSP (SPI.bin at the time of writing). +You still need two more binary blobs. The first comes from the original +firmware image available from: + +http://firmware.intel.com/sites/default/files/2014-WW42.4-MinnowBoardMax.73-... + +Unzip it: + + $ unzip 2014-WW42.4-MinnowBoardMax.73-64-bit.bin_Release.zip

Use ifdtool in the U-Boot tools directory to extract the images from that file, for example:

+ $ ./tools/ifdtool -x MNW2MAX1.X64.0073.R02.1409160934.bin + +This will provide the descriptor file - copy this into the correct place: + + $ cp flashregion_0_flashdescriptor.bin board/intel/minnowmax/descriptor.bin + +Then do the same with the sample SPI image provided in the FSP (SPI.bin at +the time of writing) to obtain the last image. Note that this will also +produce a flash descriptor file, but it does not seem to work, probably +because it is not designed for the Minnowmax. That is why you need to get +the flash descriptor from the original firmware as above. + $ ./tools/ifdtool -x BayleyBay/SPI.bin $ cp flashregion_2_intel_me.bin board/intel/minnowmax/me.bin - $ cp flashregion_0_flashdescriptor.bin board/intel/minnowmax/descriptor.bin

Now you can build U-Boot and obtain u-boot.rom
