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!
