  1. Closed: Re: AVR Soft-Core (ATMega103) - issues during synthesis and implementation

    Hello,

    little update: ATMega103 haven't JTAG interface, it is likely that this AVR soft-core should be programmed by JTAG programmer as ATMega128 (ATMega103 and ATMega128 are very similiar in...
  2. Closed: Re: AVR Soft-Core (ATMega103) - issues during synthesis and implementation

    Hello,

    I was very busy last two weeks (business trip) and haven't time to check programming AVR soft-core with using JTAG programmer. I am looking for board description for "Arduino IDE" which has...

    Hello,

    I did as you adviced me and change location of JTAG TCK pin to W5 of Artix7 (GPIO pin 36 of my FPGA board)

    :

    set_property -dict { PACKAGE_PIN W5 IOSTANDARD LVCMOS33 } [get_ports {...

    Hello,

    I am aware that longer delays can occure. I just wanna to try it on FPGA, but today I haven't JTAG programmer for AVR (I will have access to programer tomorrow).
    If I will try the project...
  7. Closed: Re: AVR Soft-Core (ATMega103) - issues during synthesis and implementation

    Hello,

    I added the directive: "set_property CLOCK_DEDICATED_ROUTE FALSE [get_nets TCK_IBUF]" from hint related to placement error and now I only have warnings during implementation phase, but I am...
  8. Closed: Re: AVR Soft-Core (ATMega103) - issues during synthesis and implementation

    Hello,

    this is next part of my post, it is related to errors in implementation phase (placement), after adding to constraint file all ports from top entity.

    First - this is top entity of...
  9. Closed: Re: AVR Soft-Core (ATMega103) - issues during synthesis and implementation

    This is second part of my post:

    I am a bit confused because this is soft-core with status stable and was checked earlier. Maybe reason of such many warnings is caused that it is old design (as far...
  10. Closed: AVR Soft-Core (ATMega103) - issues during synthesis and implementation

    Hello in new year 2020 ;-)

    After severals experiments with few soft-CPU (Picoblaze, Microblaze, RISC-V) I decided to try implementation of AVR core (ATMega103) from opencores.org - see link:

  11. Closed: Re: How to initialize ethernet and lwip on STM32h7 microcontroller?

    Hello,

    you don't need generate code these examples are complete. For example see the "LwIP_TCP_Echo_Server", you have sources in catalogs: Inc and Src then you have to attach files from catalog...
  12. Closed: Re: How to initialize ethernet and lwip on STM32h7 microcontroller?

    Hello,
    when you installed "STM32CubeMX" then you are able to install packages for device you need. In order to do that just open "STM32CubeMX" and then clik button <INSTALL/REMOVE> below text...
  13. Closed: Re: Running .elf file on ubuntu platform, Zynq Board

    Hello,

    sorry for answering with big delay. In field "Host name" you should give the same IP addres as in "Tera-Term" window (it was: 192.168.43.206). After copy elf file it could be necessary to...

    [QUOTE=FlyingDutch;1668043]

    BTW: this equotation is contrary and has not solutions ! Substitute 1 for a variable and check it yourself.

    See: 1^7-2*1^5-1^2 = -1
    1-2-1 =-1

    Hello,

    maybe first famiiarize yourself with one of methods for approximation solving of nonlinear equations - for example Nwewton's method. See links:

  20. Closed: Re: What is the best way to interface MCU (STM32F4 series) with FPGA board (Artix-7)

    Hello @KlausST,

    now I can say you more about assumptions to my design. I find in Xilinx Vivado free IPCore with FPU module implementation. This implementation is using DSP slices and I suspect it...
  21. Closed: Re: What is the best way to interface MCU (STM32F4 series) with FPGA board (Artix-7)

    "Really huge" means in this case up to few millions. The first dimension of tensor is usually the number of samples used to training "artificial neural network". of course vector coprocessor will be...

    Hello Klaus,

    related to 1) Yes you are right. There be many instances of 16 bit floating-point units (only two operations: multiplying and adding). Them will be used in module for making...
  23. Closed: Re: What is the best way to interface MCU (STM32F4 series) with FPGA board (Artix-7)

    I am working on some kind of vector floating-point coprocessor. I would like to use it for multiplying and adding matrixes with floating-point numbers. Yes I am aware that FPU for floating-point...
