Memory controller work continues….workaround 4MB SRAM add-on
SO here’s a couple hundred dollars of SRAM parts ordered to add on to the FPGA. It goes like this: the memory controller isn’t fully integrated yet into the J68 soft-core, so I’ve decided to whack on 4...
left-justified DAC problems continue
Here you see the analog sound waveform coming out of the DAC at the top in yellow. I think I’m getting closer……I switched from the I2S DAC to a left-justified DAC just because the LJ one is a little...
J68 is now booting from User Flash Memory on the BEMICRO MAX10 FPGA board
I’ve been struggling for quite a few nights and weekends over the last month or so. I’ve now successfully attached the J68 to the built-in User Flash Memory. This means that the 16KB (actually about ~13KB)...
LCD Test image and pixel-level detail
So I’ve managed to get a semi-working test pattern image up on the LCD. Here are a couple shots: If we zoom in about 10 times, we can see how the LCD really works, on an individual pixel level: Pretty challenging...
J68 boots VUBUG monitor on the BEMICRO MAX 10 FPGA board
Here’s an image showing a ROM monitor VUBUG running on the J68 softcore, which is in turn running on a BEMICRO Max 10 FPGA board.
VUBUG will be used until we can get our own (unwritten, so far) custom code booting!
