Axi timer not working This experiment combines GPIO and timer interrupts with polling. This causes your Main method to end, and the console to shut down. You either need to connect the TTC from the APU to provide the timer tick or you will have to modify the tcl script. Generate Mode • Counter when enabled begins to count up or down • On transition of carry out, the counter a single 64-bit counter/timer • The cascaded counter can work in both generate and capture modes • TCSR0 acts as the control and status register for "Unfortunately none of them really answers my question. Here’s a block diagram of the AXI timer taken from the data sheet. I'm using an AXI timer with the XTmrCtr driver to create a PWM output and have run into an unexpected behavior. */ #include "FreeRTOS. first call it should read 500 cycles, then 1000 cycles, then 1500 cycles, but it I created a PL interrupt and axi timer interrupt in block design. Moreover, the I am trying to get Microblaze to work with Axi timer to trigger interrupt at a certain rate. I've created a simple MicroBlaze system and am trying to trigger an interrupt, but obviously it's not working. My design has HDMI RX and TX Subsystem in it with Microblaze handling multiple interrupts (HDMITxSS, HDMI RxSS, VPhy, UARTLIte, IIC, and Timer). I've looked around and the found that the standard procedure is to use the axi timer ip with the axi interrupt controller; I just am not familiar enough with the software at this stage to implement it, your help in the #define XPAR_FABRIC_AXI_TIMER_0_INTERRUPT_INTR 121U; I am not sure how you are generating the 1Hz clock.
