    Cmod A7 programming

    Hello everyone I am working on a project based on Microblaze, which I want to implement later on an FPGA circuit of type CmodA7-35t. My objective is to make the PFGA work under an external power supply and not with USB. I am now looking to find a solution to program the FPGA in Quad SPI Flash mode. On the Digilent references I found the following example: https://reference.digilentinc.com/learn/programmable-logic/tutorials/cmod-a7-programming-guide/start. My question is how I can do it from the SDK since the project includes BLOCK DESIGN in addition to a C application under SDK. I will b
  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
  3. Dear all, i am really new in working with FPGA's and started with some microblaze application. So i build up a standard microblaze system with uartlite and some LED's. Also i generate a sine wave with the dds-compiler and now i want control the input clock of the dds-compiler for changing the output frequency. For this i started to use the axi-Timer (i don't know this is the best way for an adjustable clock) and started to write a C programm in the Vivado SDK software. Till now i don't get any output from the axi-Timer, maybe someone can help me... Thank you! Following the C-code wi
  4. Hi, I am trying to program basys3 from qspi flash. I have made a microblaze based system with qspi flash (BD attached) in vivado. I have tried the tutorial in this link below to make a qspi srec bootloader to put my application in flash. I have used FLASH_IMAGE_BASEADDR in blconfig.h as 0x47200000 (XPAR_AXI_QUAD_SPI_0_BASEADDR = 0x46000000 + offset = 0x01200000). However, I cannot program the flash for this address offset. The program fails with the error as "ERROR: [Xicom 50-47] Start address (0x01200000) is outside of the device memory range." However, if i try with small offset (0x0
