  1. I followed this forum and changed the constraint files of the Zybo Z720 in Vivado and successfully generate bitstream and the xsa file to import into Vitis. https://forum.digilentinc.com/topic/8943-pmod-as-input-and-output-gpio/ #Pmod Header JE set_property -dict { PACKAGE_PIN V12 IOSTANDARD LVCMOS33 } [get_ports { je_pin1_io }]; set_property -dict { PACKAGE_PIN W16 IOSTANDARD LVCMOS33 } [get_ports { je_pin2_io }]; set_property -dict { PACKAGE_PIN J15 IOSTANDARD LVCMOS33 } [get_ports { je_pin3_io }]; set_property -dict { PACKAGE_PIN H15 IOSTANDARD LVCMOS33 } [get_ports { je_pin4_io }]; set_property -dict { PACKAGE_PIN V13 IOSTANDARD LVCMOS33 } [get_ports { je_pin7_io }]; set_property -dict { PACKAGE_PIN U17 IOSTANDARD LVCMOS33 } [get_ports { je_pin8_io }]; set_property -dict { PACKAGE_PIN T17 IOSTANDARD LVCMOS33 } [get_ports { je_pin9_io }]; set_property -dict { PACKAGE_PIN Y17 IOSTANDARD LVCMOS33 } [get_ports { je_pin10_io }]; I am able to control the GPIO pins of port JF on the Zybo Z720 using the following code, how do I edit this so that I am able to turn on/off LEDs using the Pmod port JE instead. #include "xil_cache.h" #include "xparameters.h" #include "stdio.h" #include "xparameters.h" #include "xuartps.h" #include "xtime_l.h" #include "xgpiops.h" #include "sleep.h" #include "xil_io.h" #include "xil_types.h" #include "xil_printf.h" #include "sleep.h" #include "stdlib.h" #include "string.h" #define HOST_UART_DEVICE_ID XPAR_PS7_UART_1_DEVICE_ID #define HostUart XUartPs #define HostUart_Config XUartPs_Config #define HostUart_CfgInitialize XUartPs_CfgInitialize #define HostUart_LookupConfig XUartPs_LookupConfig #define HostUart_Recv XUartPs_Recv #define HostUartConfig_GetBaseAddr(CfgPtr) (CfgPtr->BaseAddress) #define PMODESP32_UART_BASEADDR XPAR_PMODESP32_0_AXI_LITE_UART_BASEADDR #define PMODESP32_GPIO_BASEADDR XPAR_PMODESP32_0_AXI_LITE_GPIO_BASEADDR #define COUNTS_PER_SECOND (XPAR_CPU_CORTEXA9_CORE_CLOCK_FREQ_HZ /2) #define TIMER_FREQ_HZ 100000000 #define MAX_WIDTH 320 #define MAX_HEIGHT 240 #define MAX_BUTTON 16 #ifdef __MICROBLAZE__ #define HOST_UART_DEVICE_ID XPAR_AXI_UARTLITE_0_BASEADDR #define HostUart XUartLite #define HostUart_Config XUartLite_Config #define HostUart_CfgInitialize XUartLite_CfgInitialize #define HostUart_LookupConfig XUartLite_LookupConfig #define HostUart_Recv XUartLite_Recv #define HostUartConfig_GetBaseAddr(CfgPtr) (CfgPtr->RegBaseAddr) #include "xuartlite.h" #include "xil_cache.h" #else #define HOST_UART_DEVICE_ID XPAR_PS7_UART_1_DEVICE_ID #define HostUart XUartPs #define HostUart_Config XUartPs_Config #define HostUart_CfgInitialize XUartPs_CfgInitialize #define HostUart_LookupConfig XUartPs_LookupConfig #define HostUart_Recv XUartPs_Recv #define HostUartConfig_GetBaseAddr(CfgPtr) (CfgPtr->BaseAddress) #include "xuartps.h" #endif #define PMODESP32_UART_BASEADDR XPAR_PMODESP32_0_AXI_LITE_UART_BASEADDR #define PMODESP32_GPIO_BASEADDR XPAR_PMODESP32_0_AXI_LITE_GPIO_BASEADDR #define BLOCK_SIZE 40 void startup(); XGpioPs_Config *ConfigPtr; XGpioPs output; int main() { startup(); while(1) { XGpioPs_WritePin(&output, 13, 1); //led on (pin 1,2,3,4) XGpioPs_WritePin(&output, 10, 1); XGpioPs_WritePin(&output, 11, 1); XGpioPs_WritePin(&output, 12, 1); } void startup(){ //initialize pins for JF ConfigPtr = XGpioPs_LookupConfig(XPAR_PS7_GPIO_0_DEVICE_ID); XGpioPs_CfgInitialize(&output, ConfigPtr, ConfigPtr->BaseAddr); XGpioPs_SetDirectionPin(&output, 13, 1); XGpioPs_SetOutputEnablePin(&output, 13,1); //pin1 JF1 XGpioPs_SetDirectionPin(&output, 10, 1); XGpioPs_SetOutputEnablePin(&output, 10,1); //pin2 JF2 XGpioPs_SetDirectionPin(&output, 11, 1); XGpioPs_SetOutputEnablePin(&output, 11,1); //pin3 JF3 XGpioPs_SetDirectionPin(&output, 12, 1); XGpioPs_SetOutputEnablePin(&output, 12,1); //pin4 JF4 }
  2. Hello: I am trying to get PYNQ onto the Arty Z7-20 by following the steps from this tutorial: https://projects.digilentinc.com/90432/programming-python-on-zynq-fpga-ec4712. I've burned the PYNQ Z1 2.6.0 ISO file (latest version) to a microSD card, but when I go to boot from the SD Card I only get the red LD13, TX/RX, and Ethernet lights to turn on. The six LED's at the bottom do not turn on as well as the done LED to signify the bitstream has been loaded. I switched the booting from to QSPI to shelve the microSD issues, but even after all the appropriate LED's turn on I'm not able to log into the board using a terminal window (I've tried Tera Term and PuTTY). When I drop down the ports I get two USB Serial Ports that show up but neither is a virtual COM port that I have read is necessary to communicate with the UART bridge on the board. I've downloaded drivers from STMicroelectronics for the VCP as well as some from FTDI for the UART bridge but neither seemed to make a difference. Any help or tips would be much appreciated, thank you. Hunter
