Previous message (by thread): [Cryptech-Commits] [sw/stm32] branch ice40mkm updated: Reworked the way iCE40-based MKM is configured. The bitmap is now stored right after the main FPGA's bitstream (was placed at the very end of the configuration memory previously). This makes it possible to flash two devices at the same time, but needs a somewhat smarter supporting routine. Instead of just looking at the very last sector of the config memy we now to need to swipe through all the sectors looking for the Lattice magic bitmap marker to determine where the MKM firmware starts.
Next message (by thread): [Cryptech-Commits] [user/shatov/ice40mkm] 01/05: Improved MKM reference design.

meisterpaul1 at yandex.ru pushed a change to branch master
in repository user/shatov/ice40mkm.

from 9ecc9e8 Script to combine main FPGA bitstream with the MKM bitmap so that the combined binary blob can be flashed using the upload script.
new 436020c Improved MKM reference design.
new 69b1374 Physical constraints for the MKM reference design
new 8a4d32c Timing constraints for the reference design. Note, that the low-frequency oscillator is not constrained on purpose.
new 6d9bf8e Makefile to build the MKM firmware. Build tested with Yosys 0.9, note that version 0.7 *which is shipped with Ubuntu 18.04) doesn't work.
new cffbc33 Don't track Lattice iCEcube2 project files
