  1. well, I'll answer my own question. Basically, just changing to the correct ldscript.ld file fixed things. Initially Vitis complained about the board config, but I ignored it, rebuilt everything and now the build works fine. The working memory is internal to the FPGA, and the external SRAM can be tested fine with the demo code.
  2. Well, I'm using the lockdown to do some playng around with the CMOD A7 board that I bought a while back. After some fighting with Vivado/Vitis I did manage to setup and build the OOB project. However on a terminal I noticed that the microblaze always seems to die on the memory test. I also saw a lot of flaky behaviour of the debug/terminal connetion. I have to restart Vitis many times and so on. Eventually I realised the issue ... the memory test seems to be stamping on ts own code area! Here is output of the running app: --Starting Memory Test Application-- NOTE: Th
  3. well, I haven't programmed using command line. Only withe the MIMAS2 util. Can you see the device with impact? that should work (there is a pdf about using impact with HS3 somewhere on digilent site) also you could try running JTAG Loader debian version just to see if it finds your HS3 that all might tell you if it is a driver/version issue or something with your programming file?
  4. and do you see the HS3 on the bus? [email protected]:~$ lsusb . . . Bus 002 Device 005: ID 0403:6014 Future Technology Devices International, Ltd FT232H Single HS USB-UART/FIFO IC
  5. no, I have only programmed with JTAG loader or the windows app provided by Numato. Do you have the latest cse drivers? I noticed that the ones in the Xilinx distro were older - this is what I now have: [email protected]:~$ cat .cse/lin64/14.1/plugins/Digilent/libCseDigilent/libCseDigilent.xml <?xml version="1.0" encoding="UTF-8" ?> <!-- Copyright (c) 2007 Xilinx, Inc.

  7. hi Billy - I have it working. Indeed, Adept runtime and utilities were the issue. I not have JTAG Loader (debian) and Impact working fine. (This is on Debian buster - testing ) process is explained here for anyone that needs it (this is about Zynq, but seems to be fine with my Spartan6 / ISE 14.7 setup). One thing to watch out for is that your build script loads the necessary paths - this is mine, for reference: #!/bin/bash # simple build script for the picoblaze assembler # compiles the code, and loads it onto target RAM # note that to make changes permanent you must then rebui
  8. I am having similar issues. I have programmed SPartan 6 with HS3 in Win 7 with some success, but for various reasons (mostly the fact that it is gettng harder to stay with Win7) I decided to set up a Linux dev environement. After some fighting, I have ISE14.7 running OK. But cable drivers is another issue. The HS3 is seen by JTAG Loader but no driver is found: <code> [email protected]:~/work/dlaserhead$ source /opt/Xilinx/14.7/ISE_DS/settings64.sh . /opt/Xilinx/14.7/ISE_DS/common/.settings64.sh /opt/Xilinx/14.7/ISE_DS/common . /opt/Xilinx/14.
  9. Hi all, I have been using MAX32 in bare-metal mode quite a bit, and I wrote some scheduler code for it. The code also does buffered debug printing over USB, and some basic error handling. I use this as start point for projects where I want very predictable timing. I find MAX32 very useful for this. The code is on Github here : https://github.com/danmcb/MAX32-RT-Scheduler and there is a write up at my website here: http://www.mcbeeaudio.com/lab//MAX32-real-time-scheduler.html This mighty make a nice start point for anyone that has been using MAX32 as an Arduino bu
  10. I just received one of these boards and have been able to carry out the most basic tutorials, but the programming interface seems very flaky. I note on other forum threads like this: https://forum.digilentinc.com/topic/4769-vivado-hardware-manager-disconnects-cmod-a7-target-in-win7/ that other users have also had issues. There has been some suggestion that USB cables are an issue. This is a problem. I previously used a different board with a Spartna FPGA and a Digilent JTAG Hs3, and I was able to program the board very reliably - in a second or two. I was able to put a Pico
  11. you need to install Eagle to do it. Thanks, never mind.
  12. I'm using Diptrace to lay out a board. I just need the mechanical positiions of holes, connectors and so on. thanks. I don't really want to get involved with Eagle, it isn't hard to create a component in Diptrace. But in fact it is (almost) an Arduino MEGA, I found some drawings for that.
  13. I've done quite some work with this board, and I have a mini-RTOS that I use on it. Am planning to post the source on github sometime, when I do I will let you know. basically it isn't that hard, if you know MPLAB - this is what is involved: 1. set up an MPLABX project with the right chip variant. 2. set up config registers on the chip to use the correct clock (external xtal oscillator is a good basic option for this board), you could also use the internal RC if you wanted although not much point. 3. write a very simple C program - I suggest just main() with a silly loop to
  14. Does this exist anywhere? I see Eagle files but I don't use Eagle, and Fritzing, not sure what that is. I want to design a boatd to work with the MAX32, would be nice not to have to work eveything out with a micrometer.
  15. Hi I see two versions of MAX32 on the website. (I have one of them) - This one (which is obsolete) and this one (current). I can't see any difference between them. Is there any? and if so how can I tell? Any part number or ID on the board, or any physical difference? Asking because I can considering using the one I have to prototype a new gadget but I'd like to use the current one. thanks Daniel
