    echo server on uart

    Hi Is there way to implement echo server on UART??

    @jpeyron Greeting thank you for reply ,I will check for other option . But i have one doubt, as I am following this link https://reference.digilentinc.com/learn/programmable-logic/tutorials/htsspisf/start .I notice that with or without srec_spi_bootloader ".elf file error is coming same ". As in following link we have to change few thing in srec_spi_bootloader in .h (flash image base address ) .c (comment verbose) saving the change , run again c file/ build all doesnot remove warning in .h and .c file. I am not sure But may be because srec_spi_bootloader is not generating correctly that why error is coming !

    inquiry on ethernet

    I start with microblaze 128kb/64 kb and 64kb/32kb local memory and cache configuration respectively. After compressing data and then generating bitstream in 128kb memory is coming 5.7kb and then launching sdk elf file is unable to generate and overflow of data as shown in picture elf_prb and while is using 64 kb option not enough memory option is showing. Its look like dead end no idea where to go i am using method https://reference.digilentinc.com/learn/programmable-logic/tutorials/htsspisf/start as mention in this and without this too(i.e dierct creating echo_server file) But one thing above site mentioned step in spi_server link i unable get any right click option as shown in that doc selet "hello world" and right click to generate linker file so i was clicking on finish and get that error. please help me. and is there any may to implement echo_server with out ddr3

    @jpeyron Greeting and thank you I mean to say that instead of 166.667 MHZ we can use 100 MHz too na as i used in my project using flash and eth_ref_clock why 25 MHz ? can We use other frequency too as 50Mhz etc. i change 166.667 to 100 Mhz because I am getting timing fail and clock was going to negative slack ,by doing that it is remove. I mean to ask significance of 25Mhz and 166.667 MHz. Actually in my project i able to generate bitsteram but its size 35 kb and bram size 32bit so while sdk lunch its keep coming not enough space in bram ,I tried to change bit to 64 but thing is that read n write bit doesnot change from 8196 and then mismatch in address bus

    @jpeyron Greeting Ok thank you, But I Have some question it is possible in this way or not(i mean using flash memory). , As you seen above there was timing fail but implementation complete is coming, basically there is negative slack i.e; set up -4.149 ns,hold 0.49 ns , WNS :-4.149 ns, TNS -2863.596 ns. How to remove negative slack/ timing fail? In Ethernet project as 3 clock we used in clocking wizard i.e clock_out1(166.667), clock_out2(200 MHZ ) and clock_out3(25 MHZ ) why we use 166.667/200 MHZ frequency and 25 MHZ clock_out3 is not connected to any port , why we required clock_out3? By hit and trail method reducing clock1 to 100 MHZ

    inquiry on ethernet

    @D@n hi greeting can you please provide link for the projects that use ethernet without DDR3 SDRAM. I used flash, and yeah I am facing problem in relaunching(in sdk) as I tick memory management option in microblaze . ... what can i do for that? and what are the alternative i can use in existing project Thanks and regards

    inquiry on ethernet

    Hi Is it possible to use Ethernet server without DDR3 ? I tried it with Flash memory (quad spi flash in vivado), Bd file picture is in attachment, I am able to generate bitsteram file but some issue in sdk file regarding memory. please go through bd file too if some change needed then tell me what can we used as alternative of DDR3 for Ethernet server??

    @jpeyron hi I am implementing Ethernet server via above mention steps, but I am not using ddr3 for memory instead that i am using flash memory.I am getting failed timing message with implementation complete .clock 1(166.667 mhz) of clocking wizard is connected exi_spi_clk, clock2(200 mhz ) with s_axi_aclk and clock 3(25 mhz ) as mentioned doc. two processor reset create , 200 mhz processor exi_reset and mb_debug_sys_reset is connected with exi_reset and mb_debug_sys_reset of 166_reset processor respectively. aresetn of flash is connected with pheripheral arsetn of 200_processor_reset. xdc file is shown in pic 1 latter i tried also make 4 port concat and connect port 2 and port 3 to interrupt of uart and axi_quad_spi . I am able to generate bit stream too now, earlier bitstream was not generating. while launching sdk some system.mss file is not generating please guide me

    FFT problems doesn't finish never

    @D@n hi I am using fft ip in vivado 2015.2 .In FFt ip two input are there s_axis_config_tdata and s_axis_data_tdata. I am giving input from saxis_data_tdata in parallel means out put is not coming as expected . and can you tell me me signification of saxis_config_tdata and for proper sinwave output from fft input should given in serial or parallel (m using parallel) and also output should taken serial and or parallel

    FFT problems doesn't finish never

    @@D@n i didn't get any appropriate forum request of md.shffat that why, ya in vivado we can use use ip, what my problem is how to connect input and output of different ip make them together, i want to know connect all devices ip like fft,adc,ram etc. In catalog ip i am able customize it but, how to use different catalog ip together or In one ip catalog (like in fft ip catalog how to add/connect other device/ip in it like adc ram etc). I am not getting idea to how to use that ip catalog in my program

    @jpeyron Hi I want to change something/adding some string in tcp_recved(highlight in blue) follow "he.png",as per as tcp_recved function include as header file(header.png) , so If I have to change something/add I have to change in header file but if go in left side of picture in include folder there is a purple folder for echo server. I can not go through that one to make changes thanks
