  1. I'm trying to run the PMOD SD IP core on a Nexys 4 DDR, using simple drag and drop from the board tap. I also add a microblaze and an UARTlite for communication. I wish to run the SDK (autogenerated) example of the SD PMOD IP core. I have used the same approach with the OLED and several other PMOD and it worked out fine. But with the SD card it fails, I get these critical warnings. I am surprised there is a problem at all, since I only used the PmodSD IP core, written by Digilent. See below. The file of concern below: Thanks for any help!
  2. Hello Digilent Community, I am working on a image processing project and was wondering if anyone had advice or could point me in the right direction. I have tried following some tutorials and example projects, but I am still trying to wrap my head around Xilinx Vivado and SDK. The project really shouldn't be very difficult, I think I am just missing some information or the best way to go about doing it. For the project I am using the Zybo z7-20 development board and want to save two images to an SD card. The two pictures are black and white frames from a video just seconds apart, so there is only slight change in the frames themselves. I want to compare the two frames and output either a black and white image of the change in pixels or a binary file of '0' being an unchanged pixel and '1' being a change in the pixel. MATLAB has the 'Computer Vision System Toolbox' 'Tracking Cars Using Foreground Detection' Simulink example that is similar to what I want to do on the Zybo z7-20 FPGA. The following figure show the original video (right) with blob detection (the green square) and the binary output image of the change in pixels in the foreground (left). I want to use the Zynq Processor and write C code to do the analysis, but I haven't found a clear way to access the SD card from the Xilinx SDK. The following figure is of my current Block Design with only the Zynq Processor as well as some GPIO to test. I am still researching and looking at examples to compare, but wanted to see if the community had any pointers or if someone has done this before. I am a college student and I have been really interested FPGA's and digital design for the past 6-9 months, but I have mainly written my own Verilog code and haven't worked with block design or running C code on any of my designs. Any comments or suggestions would be great. Thanks!
  3. Hi, I'm trying to Booting My C++ Application from SD Card, I do the following actions: 1.start Vivado software. 2. New Project. 3. Select Zybo from Board lists. 4. Create Block Design. 5. Add Ip 6. Add Zynq7 Processing System. 7. Run Block Automation 8. Route M_AXI_GP0_ACLK pin to FCLK_CLK0 pin. 9. Validate Design (no error). 10. create wrapper 11. Generate Bit stream 12. Export> Export hardware (include bitstream). 13.launch SDK. 14. Create new application (c++). 15. Write my code #include<stdio.h> int main() { while (true) { printf("sin\n\n"); } return 0; } 16. save 17. create new application Name: FSBL Os platform: Standalone hardware platform: design_1_wrapper_hw_platform_0 Processor: ps7_cortex_a9_0 language: C Board support package: create new 18. slelect "Zyng FSBL" template 19.Create Boot Image 20.select *.bif path. 21. add FSBL.elf as bootloader file 22. add design_1_wrapper.bit as data file 23. add Myapp.elf as data file 24.create BOOT.bin file 25. format SD card as FAT format mode. 26. copy BOOT.bin file into SD card 28. put SD card into Slot 29. change JP5 Jumper in SD mode 30. power on. But only Red LED turn on, and green LED turn off for all time. PLEASE HELP ME ABOUT THIS TOPIC (Excuse me for my bad English)
