  1. Dear All, In reference manual of Arty7-35 T, it is mentioned that it is possible to store data along with FPGA program in Quad SPI Flash memory but that approach is out of scope for that document. I have different tables of coefficients(in Excel, Text file) for each pixels where nature of co-efficient is floating point decimal numbers. Total data size is around 2 MB which includes 8 coefficients files At power on, i want to send all this coefficients from FPGA flash to PC via Ethernet. Now I need suggestion, How to store these data in Flash memory along with Main FPGA Program. What should be format for these coefficients files? Is this possible by using just one Flash memory?
  2. Dear Team, We have established Ethernet communication on Arty-7 35 T for FPGA to PC (Transmission) and PC to FPGA (Reception). We have done RTL design without using micro-blaze and On system side we are using Visual studio for sending commands to FPGA using socket programming. We are facing following problems which are given below : FPGA to PC communication works perfectly for any IP address, but When we send command from socket for PC to FPGA communication, Ethernet on FPGA only listen to xxx.xxx.1.255 - broad cast IP. FPGA does not listen to any other value than 255. What could be reason behind this? Another problem we observed related to wire shark. While having Ethernet communication, If we close wire-shark, FPGA stops sending data. We are not able figure the main cause.
  3. Hi, We are designing our custom pcb and taking arty-7 35 for reference. We have purchased JTAG HS2 cable and connected this to J8 connector of arty-7 35T FPGA. We have given power supply using adaptor. We are able to program arty7-35 in vivado hardware manager with both .bin and .bit file by changing jumpers for configuration type. We are following arty-7 programming guide for flash memory configuration. Our doubt is will these steps works if we design our custom PCB with same sets of components? Apart from that is there any dependacy of J8 connector with digilent proprietary USB JTAG circuit?
  4. Hi All, I am beginner in FPGA world. I am trying to learn how to work with Vivado IP Integrator. When i try to launch my firstProj on Launch on Hardware(System Debugger) I am getting a such kind of issue: make all Building file: ../main.c Invoking: MicroBlaze gcc compiler mb-gcc -Wall -O0 -g3 -c -fmessage-length=0 -MT"main.o" -I../../firstproj_bsp/microblaze_0/include -mlittle-endian -mcpu=v10.0 -mxl-soft-mul -Wl,--no-relax -ffunction-sections -fdata-sections -MMD -MP -MF"main.d" -MT"main.o" -o "main.o" "../main.c" Finished building: ../main.c Building target: firstproj.elf Invoking: MicroBlaze gcc linker mb-gcc -Wl,-T -Wl,../src/lscript.ld -L../../firstproj_bsp/microblaze_0/lib -mlittle-endian -mcpu=v10.0 -mxl-soft-mul -Wl,--no-relax -Wl,--gc-sections -o "firstproj.elf" ./main.o -Wl,--start-group,-lxil,-lgcc,-lc,--end-group /opt/Xilinx/SDK/2018.2/gnu/microblaze/lin/bin/../lib/gcc/microblaze-xilinx-elf/7.2.0/../../../../microblaze-xilinx-elf/bin/ld: firstproj.elf section `.heap' will not fit in region `microblaze_0_local_memory_ilmb_bram_if_cntlr_Mem_microblaze_0_local_memory_dlmb_bram_if_cntlr_Mem' makefile:35: recipe for target 'firstproj.elf' failed /opt/Xilinx/SDK/2018.2/gnu/microblaze/lin/bin/../lib/gcc/microblaze-xilinx-elf/7.2.0/../../../../microblaze-xilinx-elf/bin/ld: region `microblaze_0_local_memory_ilmb_bram_if_cntlr_Mem_microblaze_0_local_memory_dlmb_bram_if_cntlr_Mem' overflowed by 1168 bytes collect2: error: ld returned 1 exit status make: *** [firstproj.elf] Error 1 19:49:21 Build Finished (took 335ms) I try to search on google but cannot to find an answer. Can someone help to understand the reason? I am thiinking that this may be some tool setup issue. Thanks!
