Hey Tom.
I tried this project and I have had some issues. To be honest, its more likely SW "newbie" issues from me than anything else. I'm a HW guy a heart, not really an embedded SW guy. The Xilinx SDK kind of scares me alot. I was hoping I could step through a similar previous example (the OOTB GPIO demo) to see if I could figure out how to get the SDK to work. I managed this with the OOTB demo, but I think I'm lost with this one. I did the Vivado build and got a bit stream, and exported it for the SDK. That was OK, kind of. Co-incidently I always get timing violations (4 of them) with the uBlaze, but this is not the issue. Like I said I can generate the bit-file.
My biggest issue is within the SDK, I could never seem to get it to successfully program the FPGA, using the system_wrapper BIT/MMI files, together with the ELF that I believe comes with the project (using this instead of bootloop). It "runs" but nothing on the display.
And I'm not sure how I suck in the newly created bitfile, the C-code, etc. Its all a bit black magic to me. Setting up the right repositories maybe.
BTW as an aside, I did go and right up a simple state machine in Verilog to try and send the SPI commands to the display. No MCU, just a few state machines.
I must have some sequencing issue, as the display flashes briefly, but no red line appears as planned. Oh well.
Are you planning on adding some step by step instructions for the SDK? Just wondering.
Thanks
Steve
