Dear All, "I'm working with Vivado 2018.3 and a Zybo Z7020 board" I write here because I have a very strange problem in a project that I have been developing in the past months. Namely, I've been writing a verilog code to run on a Z7020 board. This code takes user input as parameters (that are hence hard-coded) and everything works fine with this project (no errors or not understandable warnings...) Now, my job is to make sure that these so-colled parameters can be changed through a serial connection from a laptop. Hence, I've packaged my module in an IP and connected it to the PS, programmed the SDK and here is the problem : Many things work but some don't. At the beginning, I thought that the SDK used a different convention to represent signed integers (two complement, only first bit changed...) and have thereby checked that the parameters sent by the SDK where equal to hard coded values in the PL... and they are! Every single bit.. I'm now out of option to understand my problem... Has anyone had similar issues in the passt? Does anyone have a clue for me? Thank you a lot, P.S. : Please do not hesitate to write a comment if you need any further infos.

Dear all, I'm using Vivado 2018.3 and a Zybo Z7010 board. I have finally finished my project (I actually owe this forum much), and I am now trying to use the board without having to open nor Vivado neither the SDK. Basically, I know that I can program the QSPI flash memory of the board so that the program can run without having to upload it. How this works is still unclear, is switching from JTAG to QSPI enough or should I do something on Vivado? However, I am also using the Zynq processor which runs an application that I start from the SDK. Can I avoid opening the SDK? The better thing would be if I could programm the FPGA through Matlab but I don't know if this is possible. Could you point me to some tutorials or the matlab functions (if they exist...). Thank you very much, NotMyCupOfTea

Well as the title says its pretty straight forward. I would like to connect a Master Port from PS to a Slave Port of the MB (PL), such that i can send data from PS to MB, but i cannot see where to enable them. Thanks for any kind of advice

Hi, I am trying to get the Microblaze working with the PS hand in hand, i.e. some program is running on the PS and some of it tasks should be outsourced to the Microblaze. My question is how do I need to connect the Microblaze with the PS such that this communication possible ? Some guide/tutorial would be awesome. Thanks!

Dear All, For the first time im trying to get the XMOD working with the PS side and print the values in a terminal. I tried a bunch of tutorials like the microzed chronicles.. I ended up using the tutorial posted as attachment, as attechments I also included my sourcecode and block design. I tried debugging by making several prints and I know the code works untll at least the "Test2" printf. During the build, no errors or anything appear. So i'm a bit confused into finding out where it all goed wrong. xadc.pdf design_1.pdf lab3.pdf

Hello to al, The system is built on the Zybo board in standalone mode. So far I had success sending interrupts from PL via GPIO. In order to reduce complexity I decided to try sending interrupts directly as it is shown on the included diagram. The RTL module is a simple counter sending a pulse once in a period of time. ILA confirmed the pulse. The application is supposed to count 50 interrupt events and quit. However, no triggering is happening. Clock freq is 50 MHz and a counter is 16 bit. The C-code is taken from two sources: Xilinx Timer-interrupt example and Avnet interrupt tutorial controlling brightness with PWM. The issue in my opinion is that I can't find the parameter called INTERRUPT_ID. The file xparameter.h has nothing related to IRQ interrupt or anything else related to the INTERRUPT_ID or INTC_ID. Below is the last used C-code snapshot. #include <stdio.h> #include "platform.h" #include "xparameters.h" #include "xscugic.h" #include "xil_printf.h" #include "xil_exception.h" #define INTC_INTERRUPT_ID 84 // IRQ [0] #define INTC XScuGic #define INTC_HANDLER XScuGic_InterruptHandler #define INTC_DEVICE_ID XPAR_PS7_SCUGIC_0_DEVICE_ID // =0 static INTC Intc; unsigned int LED = 0; // Interrupt counter void PIsr(void *InstancePtr){ // INTERRUPT SERVICE ROUTINE(ISR) LED ++; } int SetupInterruptSystem() { int result; XScuGic *IntcInstancePtr = &Intc; XScuGic_Config *IntcConfig; IntcConfig = XScuGic_LookupConfig(INTC_DEVICE_ID); if (IntcConfig == NULL) { return XST_FAILURE; } result = XScuGic_CfgInitialize(IntcInstancePtr, IntcConfig, IntcConfig->CpuBaseAddress); if (result != XST_SUCCESS) { return XST_FAILURE; } /* Connect the interrupt handler */ result = XScuGic_Connect(IntcInstancePtr, INTC_INTERRUPT_ID, (Xil_ExceptionHandler) PIsr, 0); if (result != XST_SUCCESS) { return result; } /* Enable the interrupt for the controller device. */ XScuGic_Enable(IntcInstancePtr, INTC_INTERRUPT_ID); Xil_ExceptionInit(); Xil_ExceptionRegisterHandler(XIL_EXCEPTION_ID_INT, (Xil_ExceptionHandler)INTC_HANDLER, IntcInstancePtr); Xil_ExceptionEnable(); /* Enable non-critical exceptions */ return XST_SUCCESS; } int main(void) { int status = XST_SUCCESS; xil_printf("\nLED=%d\n",LED); status = SetupInterruptSystem(); if (status != XST_SUCCESS) { return XST_FAILURE; } while (LED < 50) { } xil_printf("LED=%d",LED); return 0; } Hope someone could share insights and educate me. Thank you very much!
