  Step 1: Open Vivado Hardware Manager (and yes this is not Impact!)

  Step 2: Click on Auto Connect Icon

  Step 3: Right click on xc7a200, select "Add Configuration Memory Device"

  Step 4: Select Spansion, 256, part: s25fl256xxxxxxxxxxxx0

  Step 5: Select MCS file to flash, click OK

  and wait 3 minutes :)

• Micro Python, here it comes.. again

  This is just a demo of very old micropython port for MicroBlaze, it is running on MEGA65 PCB rev 1 board with 1Mbyte RAM mapped as system memory.

  Mouse programmed SoC on MEGA65, big picture in Vivado IPI.

• C65 is alive... again )

  Back home from reVISION, trying out latest bit stream from MEGA65 team, and here we are up and running. Need find a keyboard now !!

• VGA here it comes...

  Ready for testing...

  Why is the image on the Display so dimmed? Well what would you expect if you tie BLANK input of VIDEO DAC to static value?

  Found and fixed, much better now. The image on Display is actually pretty sharp, the handy camera snapshot is not the best.

• POWER OK, No SMOKE!

  Close timing, the board is alive, LED's are working, FPGA is booting from SPI Flash. Now the fun can begin.

• Waiting for PCB...

  Antti Lukats • 04/11/2017 at 14:11 • 0 comments

  Excited the PCB should arrive tomorrow before 0900 !

  A fresh new Commodore since what year? ;)

• reVISION here comes Xilinx FPGA...

  We submitted the files to Brandner PCB only about 57 minutes after the official urgent order deadline:

  This is how it looks. PCB is in production, expect delivery from fab next tuesday, so delivery on 3rd working day from day of order. Ah yes we have to produce it then on Wednesday and ship on Thursday latest to reach the party in time..

  And yes we did rush so much to be ready for reVISION party 2017 ...

  Funny is that reVISION is also Xilinx new brand name, I happened to be at reVISON Summit 2017 in Nürnberg and was captured there next to an cobot:
  

  I guess the reVISION in Saarbrücken would be fun too. Well if not me than the MEGA65 PCB should get there this year.

• 2 hours for PCB deadline

  time is running up:

  We had to make some executive decisions, as we did run out of FPGA IO pins, one the of 50 pin IDC headers for user extension was swapped in favor to 3 PMOD connectors.

  All connectors placed, PCB outline fixed also. Routing left.
