  1. I'm using Vivado 2019 and a Zedboard, trying to implement "HelloWorld" in PS and output "Hello World" at PC terminal.but it doesn't work. usb-uart and usb-jtag is connected with PC (Win10) i'm using mio-46,47 to uart0 please help me... my step: 1. vivado open block design > HDL wrapper 2. run implementation 3.Export Hardware 4. launch SDK > new application project 5. open putty for monitor (COM4, speed is 115200) 6. SDK run configuration and the setting as following > Run 7. run result as following 8. the com port terminal is nothing... please let me know where i do the wrong step.. thank you very much.!!!
  2. Hi everyone, I know that the CPLD starter board that features the XC2C256 is deprecated but can someone provide a few links with a "hello world" application? A blink LED or anything to get me started and at least check if I have my toolchain set up properly. Also, I am using xilinx ISE webpack but a few people have mentioned that vivaldo might be a better choice because xilinx doesn't support coolrunner anymore through webpack(?). I see the devices on the device list so I don't understand why I should use vivaldo. Thanks!
  3. Hello, I'm trying to get a Hello World app to work using a chipKit Pro MX4. I've followed along with example code written for a Starter Kit board changing and making adjustments to the MPLAB X Harmony configurator as I go along, although there really isn't that much difference between the two as the sample.x project is written for a PIC32MX795. I'm using the USART driver with the following code in system_config.h (See the configuration code generated by Harmony and stored in the system_config.h file). My state machine simply adds a bunch of strings to the Transmit Buffer Queue using the DRV_USART_BufferAddWrite function provided by the driver module. This seems to be working successfully as I do receive a valid handle from the function. The problem is there is nothing being sent. I have, in addition to using the trainer board, brought this up using the simulator and there really is nothing being sent on UART 1. So, when the Transmit Buffer Queue fills up with buffers to be sent the USART driver begins denying any further attempt to add message to the queue. All of that works as expected. The sample application seems to be doing nothing else significant and when run on simulator (since I have not trainer board for that part) I see the text appear in the USART 2 Output window. (Note: the MX4 board uses UART 1 for the J8 connector and so I've modified to use UART 1 instead of 2... no big deal there.) I've been up most of the night or all night pouring over data sheets and the like trying to figure this out, but I've come across nothing significant. My thinking on this is that the simulator knows nothing about the specific card and its many connections. It knows only of the microcontroller family and part so that means that it's not really something specific to the chipKIT MX4 board, but some difference in the part itself. We all know how terse datasheets can be, so I must be missing something basic with regard to PIC32MX vs. PIC32MZ. That's why I have focused mainly on looking at the part's documentation. My question is: Has anyone else done anything like this, or ran into a similar problem, or maybe someone else has been able to get this working and I'm missing something basic? I just have been very unsuccessful at figuring this out. I'm not new to embedded systems, but I'm an older guy trying to refresh and update my skills after being out of the industry for a long time. I most certainly could be missing something obvious. As I said I've been up many long nights persevering. Any help would be greatly appreciated. This is the code generated by Harmony in the system_config.h file. I've also included my state machine and its header file which is simple. There isn't very much code here that wasn't generated by MPLAB Harmony Configurator, so that's adding to my being stumped. I'm wondering if there is something deeply hidden in the Harmony framework that is actually malfunctioning. I just can't be sure. I look forward to your response. Thank you much. // ***************************************************************************** /* Clock System Service Configuration Options */ #define SYS_CLK_FREQ 80000000ul #define SYS_CLK_BUS_PERIPHERAL_1 10000000ul #define SYS_CLK_UPLL_BEFORE_DIV2_FREQ 48000000ul #define SYS_CLK_CONFIG_PRIMARY_XTAL 8000000ul #define SYS_CLK_CONFIG_SECONDARY_XTAL 32768ul /*** Ports System Service Configuration ***/ #define SYS_PORT_AD1PCFG ~0xffff #define SYS_PORT_CNPUE 0x0 #define SYS_PORT_CNEN 0x0 #define SYS_PORT_B_TRIS 0xc3ff #define SYS_PORT_B_LAT 0x0 #define SYS_PORT_B_ODC 0x0 // ***************************************************************************** // ***************************************************************************** // Section: Driver Configuration // ***************************************************************************** // ***************************************************************************** // ***************************************************************************** /* USART Driver Configuration Options */ #define DRV_USART_INTERRUPT_MODE false #define DRV_USART_BYTE_MODEL_SUPPORT false #define DRV_USART_READ_WRITE_MODEL_SUPPORT true #define DRV_USART_BUFFER_QUEUE_SUPPORT true #define DRV_USART_CLIENTS_NUMBER 1 #define DRV_USART_SUPPORT_TRANSMIT_DMA false #define DRV_USART_SUPPORT_RECEIVE_DMA false #define DRV_USART_INSTANCES_NUMBER 1 #define DRV_USART_PERIPHERAL_ID_IDX0 USART_ID_1 #define DRV_USART_OPER_MODE_IDX0 DRV_USART_OPERATION_MODE_NORMAL #define DRV_USART_OPER_MODE_DATA_IDX0 #define DRV_USART_INIT_FLAG_WAKE_ON_START_IDX0 false #define DRV_USART_INIT_FLAG_AUTO_BAUD_IDX0 false #define DRV_USART_INIT_FLAG_STOP_IN_IDLE_IDX0 false #define DRV_USART_INIT_FLAGS_IDX0 0 #define DRV_USART_BRG_CLOCK_IDX0 10000000 #define DRV_USART_BAUD_RATE_IDX0 9600 #define DRV_USART_LINE_CNTRL_IDX0 DRV_USART_LINE_CONTROL_8NONE1 #define DRV_USART_HANDSHAKE_MODE_IDX0 DRV_USART_HANDSHAKE_NONE #define DRV_USART_XMIT_INT_SRC_IDX0 INT_SOURCE_USART_1_TRANSMIT #define DRV_USART_RCV_INT_SRC_IDX0 INT_SOURCE_USART_1_RECEIVE #define DRV_USART_ERR_INT_SRC_IDX0 INT_SOURCE_USART_1_ERROR #define DRV_USART_XMIT_QUEUE_SIZE_IDX0 18 #define DRV_USART_RCV_QUEUE_SIZE_IDX0 8 #define DRV_USART_POWER_STATE_IDX0 SYS_MODULE_POWER_RUN_FULL #define DRV_USART_QUEUE_DEPTH_COMBINED 26 Here's my state machine and its related code from app.c Please forgive/ignore some of the unnecessary code I put in for debugging purposes. void APP_Tasks ( void ) { static unsigned long int number = 0; static char string[200]; static int messageCount; static DRV_HANDLE usartBufferHandle; int debugDummy = 1; char * pointerToString = &string[1]; int stringLength; /* Check the application's current state. */ switch ( appData.state ) { /* Application's initial state. */ case APP_STATE_INIT: /* Keep trying to open the driver until we succeed. */ { messageCount = 0; /* open an instance of USART driver */ appData.usartHandle = DRV_USART_Open(APP_UART_DRIVER_INDEX, DRV_IO_INTENT_WRITE); if (appData.usartHandle != DRV_HANDLE_INVALID ) { /* Update the state */ appData.state = APP_STATE_GENERATE_MESSAGE; } break; } case APP_STATE_GENERATE_MESSAGE: { char * c = NumberToString(&string[1], number, 9, true); *c = '\r'; *(c + 1) = '\n'; *(c + 2) = '\0'; number++; appData.state = APP_STATE_SEND_MESSAGE; break; } case APP_STATE_SEND_MESSAGE: { stringLength = strlen(&string[1]); pointerToString = &string[1]; DRV_USART_BufferAddWrite( appData.usartHandle, &usartBufferHandle, pointerToString, stringLength); if(usartBufferHandle != DRV_HANDLE_INVALID) { if(messageCount++ < 100001) { appData.state = APP_STATE_GENERATE_MESSAGE; } else { appData.state = APP_STATE_WAIT4SENT; } } break; } case APP_STATE_WAIT4SENT: { debugDummy++; int i = debugDummy; break; } default: { debugDummy++; /* PROGRAM COUNTER SHOULD NEVER REACH THIS CODE!

  4. hi all. would like help doing a hello world with the cerebot m7 sample application. Can someone provide brief step by step instructions on how to configure it to work with MPLAB? IE, download MP lab, then configure it how? honestly just want to get the sample application to work. -Jim
