Xilinx fsbl ethernet

After I change the PHY address to 0 it successfully completes the autonegotiation and reports the link speed. There after it fails and looks like it is not receiving any frames. I blamed the PHY chip differences and spend couple of days in the data sheets and no luck. At that point I thought of trying with the supplied Linux boot image till then I used the xilinx XPS and run the sample based on the hw definition file from Zedboard and didn't check the LAN.

Out of the 3 boards we have I checked two and got the same results.

Any help is much appreciated. Although it does not cover usage of the ping command, it does cover the http, ftp, and ssh support that should be available using the out of box SD card content. Have you checked this document to see if any of these Linux features are operational over your Ethernet connection? Hi Kevin, Thanks for the prompt reply. Only the self pinging is not working.

Self Pinging Loop back is working on the ZC board. I tried with the IP address Both way no differences I wasn't sure any other settings I like to get some explanation why self pinging is working on EZ and not in ZedBoard causes the ethernet chip not working. I see the error as DHCP server not responding but the static one also not picking up. Can you please elaborate on what you mean by the self-pinging?

Are you talking about pinging the address of lo or eth0 adapters? I tried pinging both adapters on my ZedBoard and there was no response which seems to match what you are seeing. First I brought lo up using the following command:. Not sure if I have a good explanation for this behavior though.

Kevin, Yep. I see the same over here. Once I enable the loop back ifconfig lo up I can ping the The other command is not required. Explanation could be ZC it is enabled and Zedboard it is not enabled by default. Looks like I am missing some setting still in driver level at BSP code. Do you have any suggestions other than the PHY address any other specific settings required for Marvell 88E chip compare to 88ER?

So if the driver attempts to reset the PHY in software during configuration which the QNX driver does when unable to locate package python2 termux startedit will fail. I'm posting for anyone else who happens across this thread. Hopefully, this will be useful for somebody.Fixed in the Zynq Silicon. It runs entirely on the SoC e.

It is adapted to the Petalinux project settings Console, boot devices, … and to the hardware itself by importing the hardware handoff file. U-Boot is a widespread module on embedded systems. U-Boot provides an interactive shell and persistent storage for environment variables. To select between the different boot sources, set the boot mode DIP switches. As the switches pull down, the polarity is inverted compared to the Enclustra reference manual.

As JTAG booting is slow, transferring the whole fileset is not recommended. The following command should boot without assembling the prebuilt files first, but does not work with Petalinux It can be used to store the boot images, but as erase and write speed is low compared to NAND flash and the number of write cycles is limited, it should not be used as the main general purpose storage. NOR flash does not require error detection and correction mechanisms in the software layer, which makes it ideal for raw binary storage avoiding the complexity of file system layers.

The physical storage space is split in erase blocks, which dictate the smallest write sitze: If only one bit is changed, the whole erase block must be read out to a temporary storage, modified there, erased in flash and then the flash rewritten from temporary storage.

U-Boot as well as the Linux kernel enforce that these parts are aligned to the erase block size. If both of them are already loaded to flash, you can skip the JTAG step. Interrupt the countdown with a random keypress which leads to the U-Boot prompt. Remember to hard-reset the HDROB after the update or you might keep using an outdated bootloader or bitfile.

Booting from SD card is slower than from QSPI, but allows for easier updating by transferring the firmware files on a regular desktop computer. The SD card holds both the firmware images as well as the root file system; the U-Boot environment however cannot be stored to the SD card.

As the U-Boot environment is not stored on the SD card, special care must be taken when switching between boot modes, e. Hence it is not sufficient to switch between the modes with the DIP setting, but also the environment must be rewritten or reset using the run eraseenv command at the U-Boot prompt.

Introducing the T1 Telco Accelerator Card

Take care not to partition using others, like GPT. There is no binary disk image available, so it must be transferred keeping links, special files and permissions intact e.

In order to access the raw SD card device, the script must be run as root user or with the sudo command. If the root user cannot access the place where the PetaLinux project files are located e. Boot sources To select between the different boot sources, set the boot mode DIP switches. The switch positions are sampled at boot time only.

Changing them without reset has no effect.We only include the first two in the boot. First, let's download the code for zynq-boot, which contains what we need to set up a Zedboard to boot Android.

By packing the zImage and initial ramdisk image into a boot. So all we need to do is the last 2. Except the Xilinx kernel seems to require some other configuration registers to be initialized.

Over time, perhaps this configuration wil be moved to the kernel to simplify this process. If we take a look at the contents of Zynq-Boot, one of the files of interest is clearreg. This file is compiled and linked with zImage so that this code is the entry point. Then it contains the data table itself.

Each entry is two bit words: a configuration value to write and an address at which to write it. We could make the SD card image all in one step, but if you're reading this, you are probably interested in some of the details.

There is some chatter from the different steps. This step creates the other files needed to boot Android on the zedboard and puts them in the sdcard-zedboard directory. Insert the SD Card into the Zedboard and turn it on. You will need to plug in ethernet so that you can communicate with the zedboard over TCP. Hi, I read these steps and git the zynq-boot repo and find that clearreg. S has been updated as clearreg. I am interested in booting Minix 3 on a ZedBoard.

I think that it is good idea to boot it without U-boot. But Minix image is far from a Linux image. I don't know how to arrange them in the final image. Do you have any idea about this? Reply 5 years ago on Introduction. We rewrote the the asm file in C once we discovered that FSBL had initialized the stack before calling, making it safe for C.

To boot Linux, zynq-boot creates zcomposite. You can do something similar with the minix kernel. By jameyhicks Follow.

We need more than boot.Xilinx standard FSBL when compiled with default settings is in "quiet" mode, with no console output if something goes wrong.

In such cases adding. Is a command-line tool from Xilinx to write nonvolatile memory connected to Zynq PS. With current versions of tools there is minor problem with file extensions: on windows platforms only lowercase. Boot bin generated with petalinux would be however generated as BOOT. BIN with uppercase extension.

Zynq SOC's Gigabit Ethernet Part 2 - Vivado Project

As a workaround the image to be burned has to be renamed with lower case extension. The name of the image can be anything, just the extension has to be bin in lowercase. Note: Xilinx how-to " Prepare Boot Image " is incomplete and out-dated as well rev 23 from November Xilinx how-to does not show a bitstream at all, and lists files to be included that are not needed with latest petalinux standard kernels. Defaults by SDK, dummy "hello. This is how SDK wizard does it by default, this order should not be changed.

As 3rd file is normally the second stage bootloader u-boot. For SPI Flash images linux image should be added as well as last file, with correct offset it must match the offset u-boot is expecting it. Note: petalinux-package As workaround the boot images should be generated with bootgen using manually created bif files. This special image does not use or initialize any PS peripherals including external DDR memory, it also does not attempt to configure the PL portion.

The same image can be used on any Zynq device, if the SD boot process succeeds at all then code in the image will be executing.

No labels. Powered by Atlassian Confluence 7.A little while back, a Raspberry Pi form factor FPGA board called the ZynqBerry caught my eye and I spent some time with it to bring it up as a ready-to-go tool in my arsenal of development boards. I quickly found that I needed an embedded Linux image in order to utilize the Ethernet port and four USB ports on it which led to previous post here. This prompted me to want to put together an outline of my design flow for FPGA development from start to finish all in one place.

In Vivado, there are a ton of pre-packed IP intellectual property blocks to cover a ton of basic functionalities for you to utilize such that you can focus more so on the custom parts of your design instead of re-inventing the wheel over and over again on things like UART drivers, SPI interfaces, etc.

Now this step is optional if your design is purely your own custom HDL. Another cool thing about the block design in Vivado is that you can package an entire project into its own IP block and place it into a local repository to use in other designs.

Instead, straight from the TCL console in an empty project run the following command:. Once the design passed validation, I save and close the block design. This top level wrapper will instantiate an instance of the block design that then makes it available to any other instances of HDL modules. There are two options when creating a new HDL wrapper: allow Vivado to manage and auto-update it, or manually configure it as desired.

xilinx fsbl ethernet

I then set my own file as the new top level file for the design and disable NOT delete the wrapper auto-created by Vivado. If I need to update the block design, I re-enable the auto-created HDL wrapper and set it back as the top before going into the block design to modify it. This super convoluted, indirect way to do this is hyper specific to the Vivado IDE. All of the design is contained with in the block design. When I downloaded the constraints set to the ZynqBerry from TrenzI noticed that they had done something similar and they had also made a separate file for each peripheral.

I might start doing the same in the future for bigger designs since it made everything so readable. Once the constraints have been set, synthesis and implementation needs to be ran to build the design and route it through the targeted chip.

xilinx fsbl ethernet

This step is a lot of watching and waiting. If there are any errors or critical warnings, the resulting output error code and Google are your best friend. After the design is routed in implementation, the setup and hold timing of all paths within the FPGA fabric are calculated. If the design does not meet proper timing constraints, a critical warning is generated after implementation is complete.

There are a multitude of techniques to fix timing issues depending on their root cause. Once any errors and critical warnings are resolved, the design is ready to be packaged up into a bitstream to export to SDK. Now that the hardware design is complete and verified, the next step is to export it to SDK where the appropriate embedded software can be added to the design. Technically, you can export your hardware definition and create the SDK workspace wherever you want to, but as I mentioned previously, the most error-proof way is to allow Vivado to place things where it wants to.

Even though I am ultimately using PetaLinux to create an embedded Linux image for the ZynqBerry, the first stage bootloader to launch the Linux kernel is a bare metal application that is created in SDK. When creating a new PetaLinux project, I personally like to create it in the same folder as my Vivado project, so I will change directories into that folder prior to running the following command to create the project. Change directories into this project folder before running any of the project configuration commands.

The hardware settings is where the kernel is configured to boot from the SD card for this design. All of these settings are the same between this full build out of the ZynqBerry and my previous post where I was just focused on interfacing with the Ethernet port, which you can find here under step 2. The Linux kernel is responsible for starting up and managing the resources processes and peripherals applications in the OS are using.

In a sense, the kernel is basically the glue between the operating system and the hardware. The ZynqBerry requires the following configuration:. With everything configured in the kernel and root file system settings, the next thing to do is build out the device tree. The structure of the device tree file follows a simple node with given properties format.

By looking at this device tree and corresponding comments you can start to get an idea of how a device tree works. With everything configured and the device tree built, the project needs to be built which will call all of the various compilers needed to create the final output files for the kernel image and root file system. If the board were being booted from some sort of on-board memory, then this boot image file would also include the kernel, device tree, and root file system.This content is republished from the MicroZed Chronicleswith permission from the author and Hackster.

One of the beautiful things about FPGAs and heterogeneous SoC like the Zynq is that we can reprogram them in the field, often remotely. This is great when we want to update algorithms, increase performance or fix a bug; however, what happens if in a remote update goes wrong?

The last thing we want to do is brick the system, if an update goes wrong. This is where MultiBoot comes into play. In the simplest manner, MultiBoot enables us to have multiple boot images in the configuration memory. In this blog, it is fallback MultiBoot and its implementation that we are going to be examining. In this post, we are going to target a MicroZed board.

MicroZed target board. The first thing we need to do is to create two complete applications. One application will be the one which can be updated and over written, and the other is the golden image. Xilinx SDK application with the created projects. Vivado hardware manager. The first thing we need to do is to add in a configuration memory.

For the MicroZed board, select s25fls For the initial updatable image that is written at offset 0 in the memory, we should erase the entire device and then load in the updatable boot. For loading in the golden image, we use the following settings. Power cycling the MicroZed will cause the board to boot, and as there are no errors in the updatable image, you will see the first image loading.

Of course, while this works we want to ensure the golden image will be used if an error occurs. Therefore, we need to spoof a failure in the updatable image. To spoof a failure in the update image, we are going to make a modification to the updatable FSBL.

Within main in main. Instead of handing off to the application, it will simulate a failure of the loading process and ensure a fallback to the golden image. Once this has been completed, we need to rebuild the boot. When power cycled, observing the output in a terminal will show very clearly the fallback occurring.

If we have a pure FPGA-based solution, we can still use a fallback solution. I will cover this in a future blog. We want our products to be field updatable over ethernet, sometimes products are located at remote areas, with no physical access. There's only a network connection which we can use to communicate and power cycle stuff.

I can see the following 4 scenario's:. This is what you described above. In that case adding an external networked controller with JTAG something a built-in SmartLynq would be a great solutionBy using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
