content: I am having an issue with a Xilinx Z7020 on a Microzed board.I'm trying to send data out of the device to a bulk IN endpoint. I frequently get status code 1412 returned from EpBufferSend(), similar to this forum thread:https://forums.xilinx.com/t5/Embedded-Processor-System-Design/Is-this-a-USBPS-bug/td-p/510393and this one:https://forums.xilinx.com/t5/Embedded-Processor-System-Design/Zynq-Baremetal-USB-Device-Running-out-of-dTDs/td-p/669855The first thread mentions the solution is to zero out the memory before calling ConfigureDevice(), but the example shipped with SDK 2016.04 does that.https://github.com/Xilinx/embeddedsw/blob/master/XilinxProcessorIPLib/drivers/usbps/examples/xusbps_intr_example.c#L253Calling EpBufferSend() once with a small buffer works OK and I can read the bytes out with WinUSB's ReadPipe(). But I would like to send a continuous stream from the device and read it on the host. When I try calling EpBufferSend multiple times, I get status 1412. Why is this happening and what is the proper way to send large amount of data from the device to the host on the zynq using bare-metal?Thanks for any suggestions...@grouchobyte

content: As a random curiosity I decided to see if I could use the GTX transceiver in a Xilinx Kintex-7 FPGA as a very fast (theoretically 10GSPS, my current setup limits me to 6.75GSPS) 1-bit ADC.I fed the output of an LNA into one of the transceiver pins (a balun would have been better, but I didn't have one and didn't fancy trying to build a wideband microwave one), captured a total of 1M samples using Vivado ILA, and ran an FFT on them in Python. I was using a single MAAL-010704 which is not nearly enough gain at higher frequencies but I was having oscillation issues so couldn't cascade two as I was hoping to.Attached is the spectrum I see with a WiFi device transmitting nearby - it's not brilliant but it's a proof of concept at least...

I'm a long term Altera user and not too interested in switching but I don't want to pay for the NIOS II. Currently to use the Mico32 I generate the HDL write the software, compile, convert the output and add it into my HDL. This is a long winded process that isn't viable for big projects. Does anyone have any experience in using JTAG (through GPIO or host JTAG) to configure and debug the Mico32 in a non Lattice FPGA?ThanksBoscoe

content: I think that ARM is offering Cortex-M0 for free (as in beer) for playing around and at a reduced cost for commercialization. That one comes with fantastic support though. And you would be able to use any OpenOCD-compatible debug probe to program and debug it (if you gave it the SWJ-DAP option instead of the simpler SW-DAP that requires SWD. In fact you can even try internally chaining the SWJ-DAP into the JTAG pins of the FPGA so your USB Blaster can go immediately from Quartus to Eclipse for debugging.However I doubt if the smaller FPGAs can even take half of it though.

content: Also to mention that ARM would give you the Verilog version of M0 without debug at no cost and you can implement it in almost any FPGA and use keil to compile the code for it,Cortex M is the best option for embedded with lots of supporting software, I think anything else would be shooting yourself in your foot considering that we have 0.6USD Cortex devices from ST and others. Also if you are interested I can supply you the ST parts @ 0.6USD to you.

I have disassembled and made circuit for terasic USB blaster, but they are using obsolete chips just like original altera jtag.Now why the hell altera is not making jtag by using FTDI chip itself? It does support JTAG, so why not just implement it, and use single chip ? Does any one know how i can implement USB Blaster that can work with quartus software from chips that can be bayed in digikey ? I did some research , but was unable to find good solution for this problem, maybe others did something similar ?I will have lot of spare unpopulated boards afterwards

Also if you are using SRAM-based FPGA this MCU can perform the loading of FPGA code in place of the usual SPI flash, and thus you can deploy usual MCU OTA update technique on the FPGA too by packaging the FPGA code update as part of the MCU firmware update.

content: If you are willing to write your own JTag programming utility (I had a Cyclone III bootprom update utility which ran in the PC in the background & waited for a universal hot-key combination which auto-self-programmed my firmware through an Ethernet-port on the Cyclone III), any small USB MCU where all you have to do is read & write the IOs from your PC app will work. FTDI already has a USB2.0 chip that does this, all your coding will be on the PC. Quartus does provide the chain description files and programming map files. Now, integrating this home-brew programmer into Quartus or making it directly internally compatible is a completely different story.

content: The program you want is called iMPACT and it is part of the WebPack ISE 14.7 package (free).If you search Google you may find a way to install iMPACT without installing the entire ISE.I don't know anything about serial numbers. I don't even know how you would find it buried in tons of startup code. In fact, you may not even be able to read the contents of the configuration EEPROM. It's been known to happen that this stuff is all encrypted. It depends on the logic family. Personally, I don't think there will be a positive outcome.

Altera Cyclone V SoC FPGA talking to HPS SDRAM - Page 1
Forum section: electronics / general

author: macgeorge
author_rank: Newbie
timestamp: July 28, 2016, 06:06:54 am
content: Coming from the world of microcontrollers, I have recently purchased a Terasic De0 Nano SoC FPGA board and currently testing small projects focusing on the FPGA fabric of the chip.While trying to build a VGA controller, I used an "On-Chip Memory" component to store pixel data at the beginning. However, as the FPGA memory space is not enough to hold a frame for a common VGA resolution, the external SDRAM needs to be used. For the De0 nano SoC board, the SDRAM chips are connected to the HPS portion of the chip, so a bridge between the FPGA fabric and the HPS needs to be implemented.I am not interested (at the moment) into having a memory space which will be transparent to HPS as well, so as a first step, I limited the SDRAM used by the HPS (which boots into Linux from an SD card) from 1GB to 768MB.To do this, while in uboot, the following commands need to be entered:Code:setenv mmcboot "setenv bootargs console=ttyS0,115200 root=${mmcroot} rw rootwait mem=768M;bootz ${loadaddr} - ${fdtaddr}"saveenvIf for any reason you need to go back to the default setup then the following commends need to be entered:Code:env default -asaveenvIt was interesting to see that if I reduced the SDRAM to 512MB, then Linux could not start (error while booting), I don't know if anyone else can confirm this behavior.So, if I understand correctly, there are now 256MB for the FPGA to play with, which will not interfere with the hard processor.The Golden Hardware Reference Design (GHRD) project, provided as an example in the documentation includes all the settings for the setup of the HPS in QSYS and the port mapping of all the pins.However, even if the SDRAM timings are set on the GHRD, an FPGA-to-HPS SDRAM interface is not setup. Moreover, this interface can be either Avalon or AXI based.So my questions are:1) Is there any example project which implements the complete bridge from the FPGA to the SDRAM controller?2) Would an Avalon type SDRAM interface be more preferable, so as to resemble to the On-chip memory component, which is fairly straight forward to implement?3) What components need to be added in QSYS to complete the connection?Thanks in advance!

author_rank: Super Contributor
timestamp: July 30, 2016, 05:06:02 pm
content: The whole bridge thing is pretty picky.The memory controller has to be configured to open its channel to the FPGA and the FPGA design needs to have the HPS block put in to Qsys.If something is not set up properly it tends to lock up when you try to use it. Such as the Avalon bus being ethernally busy or whatever tried to issue a read on the HPS side getting in to an ethernal wait.I have a thread on the Altera forums that explains the basics of the bridges and how to make them work in bare metal C

The power should be 7-9V DC connected to the center positive input jack J14, which is regulated to 5V DC by an on-board 7805 regulator.The parallel port can be used to program the EPM7128SLC84 using software that supports a parallel port interface ByteBlaster programmer.Maybe Quartus II 13.0, Service Pack 1 was the last version to support the EPM7128SLC84. You can download the Web Edition for free here:https://www.altera.com/downloads/download-center.htmlLearning to program a CPLD in VHDL would be a completely different experience than programming a Propeller or Arduino controller. It might be something you find interesting and useful to learn some of the basics even if you have no real need to learn anything about it.

content: Hi Guys,I've written a program in VHDL to access CIS and get data and transfer the data over USB using cypress USB transceiver CY7C68013A.CIS : 1728 Pixels/Line, Output in three parts of 576 bytes.CIS clock speed : 6.25Mhz, Max 8 Mhz.FPGA : Cyclone III-EP3C25Q240C8N.ADC : AD9200, 1st sample appears on the 5th clock hence first 4 clocks cycles are skipped for every line read.Am using altera Dual Port RAM to get datas from the three outputs simultaneously and storing the datas in to 3 DPRAMs once this operation is done then I read the datas from DPRAM sequentially 1, 2, 3 and write the datas into cypress USB transceiver.Problem:When the image is created in the GUI, last four bytes (573,74,75,76) of the output is shifted to the first four bytes(1, 2, 3, 4). This four byte shift happens in all the three outputs.I couldn't figure out what is the problem in my code.Please Help. Thanks in advance.

content: Hi,Thought I would post this as I could not find any info if the cheap programmer had problems with SignalTap or not. Hopefully it will be useful for others.Been using my cheap clone ("Rev C" £3 GBP or so from ebay) to program Altera FPGAs for a while without problems.Tried to use it to with the Altera SignalTap logic analyser recently, and got "Invalid JTAG Configuration".Was not sure if it was the cheap programmer that was the problem, or something else.This was work work so I splashed out and got a genuine Altera USBBlaster II (Mouser was the cheapest, but still expensive!)The problem no longer occurs, so it looks like the problem was the cheapo programmer after all.

They are all already doing this with external FPGA boards for the last two years.If (not much of an if, but when) they get adopted on those data centers it will bring the cost down, so we do have the Cloud to thank for this to become more mainstream.Edit: Altera has had OpenCL toolchains available for their high end FPGAs for a couple of years as well.Edit2: Correction, it has been four and a half years since they announced it:https://www.altera.com/about/news_room/releases/_2011/products/nr-opencl.tablet.htmlSo my bet is that they are going to hit the floor running.

You need to add a separate UART peripheral.From there, you have two options:1. Utilize your own routines to send data to UART peripheral register and read data from there2. Go to Nios BSP options in Eclipse and select your UART peripheral as STDIN/STDOUT. In this case, your printf() will print to UART peripheral.

So, yeah, if you're using the supported devices it's free. Some evaluation kits comes with a device-specific DE voucher, but this is worthless than I can tell if it's one of the Webpack-supported devices. Not sure if the DE contains bundled IP missing in the Webpack, that's a possibility.They really don't make it easy to determine what the difference is.(BTW, they just recently made Webpack a lot more useful, it used to be the high level synthesis tools weren't included, but now that they are frankly I'm not sure there's a good reason to even redeem a device-locked Design Edition voucher.)
