I've almost done with the RTL design for a first, very limited mkmif module. The current version will only support reading and writing 32-bit words to the specific Microchip memory. (including mem init and mem command handlingt). I've got 10 chips of the specific type from Mouser and are modifying one of the old entropy boards to connect it to the Novena. When this works we can add tamoer-zeroisation functionality etc. But for the bring up we should at least have something to test the MKM functionality from the FPGA with. - -- Med vänlig hälsning, Yours Joachim Strömbergson - Alltid i harmonisk svängning. ======================================================================== Joachim Strömbergson Secworks AB joac...@secworks.se ======================================================================== -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBCAAGBQJXHy+/AAoJEF3cfFQkIuyNXrkQANfqD6WvV3D9x5i/u0coIAgF LGqDjuxpUIXvSx8EgNkU/diSL1ULbqQorNVQk0lfxavE8PC6I3YDlgRkDsFsFp+e HuPvNQbyxbm7KhILGIq0l3ANePRBwpvAiPHWQAxgz/IPghHriTZcNh9O7lV1ktsr 9IkwFCBzEKQ6SxtCp2/CtSODnH8jj1aitGE2vciOexFV3g1GuokHzQAAohhMTE05 nMni1fw7HHkv9UsMhijkMkr60RhOAn1iwZjnUjtVhsLen0MAzOAwmSp89L7RylBx tMAgjTGdns20DtcUuI1KIz4YaeOFs0NS99N4fuFWOnNnZVksU6QgFUiBLL97zYAZ EdBpYtSQadciwzp8kmTei05fJi+KFS3GUf3iuvuX7os9HWBBja67xabU8YBpeCvq 9HqBA2Rt0lGDdMGoLEvHtt461ItdQ4rmdV0cyIZzHFAZIHyXOEjMCEU+hv+7Qwsz bfQTSYnM+i1MD+j/oe92Hxa5adlb92AkqPt937kw/LWb9aAxFEntXBw11oYYCsiT GNx82RLpJVDIY1Wn262m4Or8ZMWFG61+QoFTR60UTt/liC2jWYFSziLNXoTv137w KixxgNhrC3oDyNc94HQbye0Cm6y/j12en93buWu/DJhmOOGzgk48PEwAVLZEKLMw A6ZO/UDIgUpWZUa1HeRy =rHrW -----END PGP SIGNATURE----- _______________________________________________ Tech mailing list Tech@cryptech.is https://lists.cryptech.is/listinfo/tech
