Version 1

    FlaviaLB60-00r.zip contains data files for the FlaviaLB60 implementation of the Free Logic Array, described in Flavia: the Free Logic Array and Chapter 12 of The XXICC Anthology rev 0.0r FlaviaLB60 is for the ValentF(x) LOGI-Bone FPGA board, rev R1.0.  To reduce chances of confusion, I recommend that you only install this file if you want to synthesize Flavia logic for the LOGI-Bone.

     

    FlaviaLP60 rev 0.0r adds SevenSegLB.xoe, which demonstrates using the multiplexed seven-segment display from LOGI-Edu.

     

    Unless you're using JTAG, FlaviaLB60 rev 0.0r may not work with the new LOGI-Bone-2, marked R1.5.1 on the PC board. LOGI-Bone-2 has a different I2C GPIO expander and changes its pin assignment, so programming LOGI-Bone-2 directly from BBone is slightly different.  Flavia 0.0r programs LOGI-Bone by writing a bitstream to "/dev/logibone" (used by original LOGI-Bone) or to "/dev/LOGIBone" (used by LOGI-Bone-2).  However, I haven't tried it since I don't have a LOGI-Bone-2.

     

    If you've been able to get Flavia running on LOGI-Bone-2, please add comments below telling us what worked.  If you're having trouble getting LOGI-Bone-2 to work, add comments and/or e-mail me and we'll figure it out.

     

    Note: LOGI-Bone-2 changed the default FPGA configuration mode from Slave Serial to Master Serial/SPI, i.e., self-config.  So when you power it on, LOGI-Bone-2 tries to read a valid bitstream from on-board serial Flash.  Flavia can override it, but if there's a valid bitstream it will affect whatever you have hooked up to LOGI-Bone-2 bins.

     

    There may be other LOGI-Bone-2 changes that affect Flavia.  I don't have the new board to test things at this time.

     

    Flavia is part of XXICC.  For more information on GalaxC and XXICC, see the 'blog post XXICC (21st Century Co-design) release 0.0r and XXICC's home page xxicc.org.
