b2b30936be Found the DDR3 memory is not ready when issuing the first store. 2023-04-17 19:33:13 -05:00
Ross Thompson
fbbba0e5c2 Finally we are building the fpga and can view the ila. we are getting out of reset, but we are stuck at PCM = 10b8. 2023-04-17 18:39:25 -05:00
Ross Thompson
2cbaa5c27b Dang. Looks like the reset button on the arty a7 is actually resetn. I wish they'd named it that way. 2023-04-17 16:37:18 -05:00
Ross Thompson
480562e53e Yay! We now have a functional ila and the uart connection on the pc side works. However the CPU is stuck in reset. Not really sure what's going on there. 2023-04-17 16:00:02 -05:00

4ad33d7acc OMG. the ddr3 has it's own mmcm (pll) which had incorreclty specified the input clock period as 3000 ps rather than 6000 ps so the pll was running at twice the speed. I speed the whole weekend on this. :( 2023-04-17 11:10:19 -05:00

5591b447d6 Fixed more issues with arty a7 constarints. 2023-04-16 13:25:02 -05:00
Ross Thompson
f4734c0d1b Found and fixed the major architecture issue with the mig 7 used in the arty a7 board. 
mig 7 is completely different from the ddr4 mig in that the internal pll does not general the required clocks. An external mmcm is required to general two inputs clocks and the required user clock.
 2023-04-15 11:13:28 -05:00
Ross Thompson
2f8359e6cc Realized we need a separate mmcm when using the mig 7 for ddr3 rather than the ddr4 mig. Go figure. 2023-04-14 18:02:16 -05:00
Ross Thompson
