Agilex 7 I Series Development Kit: External hardware access error when programming
I have a compiled design that I would like to test that implements Ethernet on F-Tile. When I try to program the FPGA with my bitstream, it stops and prompts me with the following errors: Would anyone know how to fix this or have insight on why this is happening?
Agilex 5 – Critical HSSI Error in JESD204B Example Design
Hi, I am bringing up the JESD204B interface on the dev kit. For this, I used the "Generate Example Design" option with the following parameters: When I generate the project and start synthesis, it reaches the "HSSI Support Logic Generation" stage, and Quartus reports the following critical error: It turns out that the generated file contains an inconsistency in the generated HSSI metadata. My fix was to replace the entry in: The problem is that after updating the Qsys file, it gets changed back to intel_jesd_RX, and HSSI reports the critical error again. If there is already a fix or workaround for this issue, please let me know. For now, I added a simple script that I run from PowerShell: that replaces this value with the correct one:
Nios V license
Hi, I need to apply Nios V free license, but in FPGA Self Service Licensing Center, I got error all the time, I signed in successfully, but it says "You do not currently have access to this site" always, as shown in the attached figure. Please help fix this issue, or is there other way to get the license? Thanks.
NiosV and juart-terminal
I had a project which works fine under niosII. I upgrade all the project with niosv and all seems fine except printing values in juart-terminal. Here is the main code : #include <stdio.h> #include "system.h" #include "altera_avalon_pio_regs.h" #include <altera_avalon_i2c.h> #include <unistd.h> #include <string.h> int main() { //* ALT_AVALON_I2C_DEV_t *i2c_dev; //pointer to instance structure alt_u8 txbuffer[20]; alt_u8 rxbuffer[20]; float co2Concentration = 0; float temperature = 0; float humidity = 0; alt_u32 co2U32 = 0; alt_u32 tempU32 = 0; alt_u32 humU32 = 0; ALT_AVALON_I2C_STATUS_CODE status; i2c_dev = alt_avalon_i2c_open("/dev/i2c"); //Ouverture du périphérique i2c et récupération d'un pointeur if (NULL==i2c_dev) { printf("Error: Cannot find /dev/i2c\n"); return 1; } //set the address of the device using alt_avalon_i2c_master_target_set(i2c_dev,0x61); //Définition de l'adresse du composant adressé 0x61 pour le SCD30 txbuffer[0]=0x00; txbuffer[1]=0x10; txbuffer[2]=0x00; txbuffer[3]=0x00; txbuffer[4]=0x81; //Remplissage du buffer pour configurer le SDC30 en Continous measurement status=alt_avalon_i2c_master_tx(i2c_dev,txbuffer, 5,ALT_AVALON_I2C_NO_INTERRUPTS); //Envoi du buffer au composant if (status!=ALT_AVALON_I2C_SUCCESS) return 1; //FAIL while(1) { txbuffer[0]=0x02; txbuffer[1]=0x02; //Remplissage du buffer pour déterminer si les données sont prêtes alt_avalon_i2c_master_tx(i2c_dev,txbuffer, 2,ALT_AVALON_I2C_NO_INTERRUPTS); //Envoi du buffer au composant rxbuffer[1]=0x00; usleep(3000); // Il faut attendre au moins 3ms avant de demander la réponse alt_avalon_i2c_master_rx(i2c_dev,rxbuffer, 3,ALT_AVALON_I2C_NO_INTERRUPTS); //Récupération de la réponse du composant si rxbuffer[1]==0x01 alors les données sont prêtes if(rxbuffer[1]==0x01) { txbuffer[0]=0x03; txbuffer[1]=0x00; //Remplissage du buffer pour la lecture des données alt_avalon_i2c_master_tx(i2c_dev,txbuffer, 2, ALT_AVALON_I2C_NO_INTERRUPTS); //Envoi du buffer de lecture et récupération des données usleep(3000); //Wait 3ms before data available alt_avalon_i2c_master_rx(i2c_dev,rxbuffer, 18,ALT_AVALON_I2C_NO_INTERRUPTS); //Read datas co2U32 = (alt_u32)((((alt_u32)rxbuffer[0]) << 24) | (((alt_u32)rxbuffer[1]) << 16) | (((alt_u32)rxbuffer[3]) << 8) | ((alt_u32)rxbuffer[4])); tempU32 = (alt_u32)((((alt_u32)rxbuffer[6]) << 24) | (((alt_u32)rxbuffer[7]) << 16) | (((alt_u32)rxbuffer[9]) << 8) | ((alt_u32)rxbuffer[10])); humU32 = (alt_u32)((((alt_u32)rxbuffer[12]) << 24) | (((alt_u32)rxbuffer[13]) << 16) | (((alt_u32)rxbuffer[15]) << 8) | ((alt_u32)rxbuffer[16])); memcpy(&co2Concentration, &co2U32, sizeof(co2Concentration)); memcpy(&temperature, &tempU32, sizeof(temperature)); memcpy(&humidity, &humU32, sizeof(humidity)); } printf("---------------------------------------------------------\n"); printf("SCD30\n"); printf("Concentration de CO2 : %f ppm\n",co2Concentration); printf("Température : %.1f °C\n",temperature); printf("Humidité relative : %.1f %% \n",humidity); usleep(500000); } } I put a breakpoint just before the printf and the values are good : but when i print the values in the juart-terminal : I can't figure out why the printf does not work as i expect. Someone could help me to understand this problem ? Thanks Eric
NIOS does not start after SW download (timing issue?)
Hi, Recently I got an old Arria V design to update. It is in Quartus II 15.0 containing the following main components (in Qsys design): NIOS II soft processor 2x UniPHY DDR3 RAM controller (soft version, not hard), 72 bit wide data running at 400MHz clock (800Mb/s) 2x Triple Speed Ethernet with 4x SGDMA The design uses only 40k ALMs out of 190k so it fits well but I have timing issues (slack) on pll_afi_clk for one or both DDR3 controllers. I can reduce it by a lot of fine tuning on synthesizer and fitter settings but when I change a bit in the design timing results go wrong and tuning has to be started again. Both FW and SW are downloaded to SRAM by ByteBlaster. I found when the slacks are big (>0.1ns) NIOS never starts after downloading the SW. When it is small or completely eliminated, NIOS starts in most of the cases (but not always). Is this normal for such a design, or am I doing something wrong? I have never seen such behaviour before. Can this timing issue affect the NIOS processor on such a way or should I search in another direction to solve the problem?Ashling RISC Free IDE fails to download ELF file
Hello ALTERA NIOSV Experts, I have been trying to execute an application using a NIOSV CPU with the Ashling RISC Free IDE. The problem is that when trying to download the elf file to a MAX10 ALTERA Development board i see an error message saying that the AShling IDE cannot determine the JTAG clock speed. I have added a Screen shot showing this event. Can anyone please suggest a solution to try ? I am currently using an ALTERA USB Blaster to connect but i have just ordered a USB Blaster II as i believe that can connect at faster clock speeds and is also more reliable. Thanks for any help,Ashling IDE scripted project creation
On Windows, is there a way to script the Ashling IDE project creation (or import an existing project)? I'm trying to clean my project down to the bare minimum for CM/repo purposes (deleting .metadata), and then have an automated way to recreate the project up to the point I can open Ashling RiscFree IDE, point to my (newly recreated) workspace, and then the project is already imported and ready to build, with all my previous settings (include paths, optimizations). Right now, the only way I can get this to work is if I manually click File -> Import and go through that dialog to import my sources from the repo. I need a hands-off way to do this. I looked at the Ashling RiscFree IDE manual, but couldn't find anything.JTAG_UART stuck in printf
I'm trying to setup a NiosV and have printf appear over the JTAG_UART. I've used only the default settings when generating the bsp (just the generate command, no set_settings). I notice when I debug, anytime I step over a printf statement, it never returns (also, no print statements appear in the juart-terminal). However, if I just do a direct pointer access to the JTAG_UART base address, I successfully see characters printed in the juart-terminal. Looking in the bsp's summary.html, it appears that it has linked the jtag_uart. Ex: hal.stdout Value = jtag_uart_0. I also have a fair chunk of CPU block ram memory (262 KB total, only using about 16 KB right now for hello world). Any ideas what the issue here is?
