Porting U-Boot and Linux on New ARM Boards: A Step-by-Step Guide - Quentin Schulz, Free Electrons
See Xilinx Answer to determine the support category Supported, known to work, Unverified, or Incompatible. Important: Please provide the full flash name, the configuration mode and the voltage.
If the configuration is not "standard" muxes, level shifters or otherprovide also the board schematics. Please provide a schematic of the NAND part and monitor the data signals on the board to verify what kind of words are read. Report any XSCT error. Try to do a brief investigation before filing a Service Request. An easy way to provide this register dump is to use the attached. Please provide the version of the tool used.
Be sure your image was built with the same version of the tool as was used to program. Please provide the boot mode settings used for programming booting from JTAG is recommended. For known issues related to u-boot, Please check Xilinx Answer You can use PetaLinux to generate the u-boot elf.
PetaLinux uses ZCU defconfig by default. NAND is not enabled in that configuration. Please provide the register settings and the calculation done to verify the NAND clock frequency. Some Debug is needed to understand where the example is failing through the SDK debugger or by adding debug prints. In To do this, we need run the following command to open u-boot configuration. See Xilinx Answer PetaLinux To verify if ubifs works well, you can load the file in ubifs to memory in u-boot and compare with its source file.
Xilinx Answer It presents a script that has been modified from the default script that PetaLinux Tools These instructions worked with PetaLinux Tools Looking for PetaLinux help? Email inquiries centennialsoftwaresolutions. The PS is the master of the boot and configuration process. Note: I don't know and cannot find the exact definitions of what happens when you "stop" and "rst -system.
Here's an example:. The con will release the PMU at 0xffdc8abc. Xilinx supplies example FSBLs or users can create their own. Write 0x to 0xFFFF Write 0x to 0xFD1A The bits are defined as:. I don't know why the other bits are not set.
FSBL executes for 2 seconds -time to download. After the download. This function just sends a PL power up request to the PMU in the script that was generated in my design. This function doesn't look like it does anything in the script that was generated in my design. In addition the DDR has been set up. The ROM boot image is not user readable or callable after boot. Script Explanation. The Linux kernel binary "Image" is loaded at 0x After this a little "mini" boot loader called linux-boot.
This little stub jumps to the Image load address after storing the address of the device tree blob into 0xf This is memory bank 2 of the OCM.
Core 0 of the A53 is then continued. This executes Arm Trusted Firmware which starts the kernel loaded at 0xGitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. If nothing happens, download GitHub Desktop and try again.

This tool is not meant to hold your hand and do everything for you the way PetaLinux does, but rather enables you to use the command line to do many of the steps typically done in the Xilinx SDK GUI. Before using this tool you must first have created your hardware description file in Vivado. Make sure you check the "Include bitstream" box. Once you have generated your hardware description file, you can copy it into this directory.
In order to generate the BOOT. These are not included in this repository because of their size and because they are often tailored for individual needs. You can set the version of the device tree generator to be used with the VER variable:.
It is recommended to use the same version as the version of Vivado you used to create your design. To install the output products to your SD card's boot partition, mount the partition to a location on your host computer e. Below is an example of using this tool from start to finish with a design created in Vivado This is an example and file names and invocations may change for your own needs.

Select the Use Authentication check box to authenticate the boot image or any of the partitions of the boot image. When using authentication, you must specify the authentication keys. The following authentication keys are available:. It should always be specified when authenticating a partition. The SPK Signature can be directly specified in cases where you do not want to share the secret key.
Select the Use Encryption check box to encrypt the boot image or any of the particular partitions of the boot image. When you enable encryption, you must specify the key file, source, and part name. If the key file is not given, then this tool generates a key file and stores in the current working directory, which is used for encrypting the partitions.
This field specifies the Xilinx part name. This is needed when generating an encryption key. You can specify the partitions and related information in the Boot Image Partitions area. Use this area to add, delete, modify, and reorder the partitions. You can also set values for enabling encryption, authentication, and checksum, and specifying some other partition related values like Load, Alignment and Offset.
The partitions list displays the summary of the partitions in the BIF file. It shows the file path, encryption settings, and authentication settings. Select from the drop down menu, if authentication needs to be made applicable to this partition.
Select from the drop down menu, if encryption needs to be made applicable to this partition. Select from the drop down menu, if checksum needs to be made applicable to this partition. When SSK authentication is not given in the main menu, user needs to make sure that presign file, which is nothing but presigned partition signature is specified. This field is enabled only when authentication is enabled.B450 dram light

Latest commit acd Apr 13, The development of U-Boot is closely related to Linux: some parts of the source code originate in the Linux source tree, we have some header files in common, and special provision has been made to support booting of Linux images. Some attention has been paid to make this software easily configurable and extendable. For instance, all monitor commands are implemented with the same call interface, so that it's very easy to add new commands. Also, instead of permanently adding rarely used code for instance hardware test utilities to the monitor, you can load and run it dynamically.
In fact, many of them are used in production systems. There is also an archive of previous traffic on the mailing list - please search the archive before asking FAQ's.

I need a non-volatile root file system and the full Linux command set so I am trying to mount rootfs from the SD card. U-boot runs great and I can launch the kernel running I just never receive the Linux command prompt. I am using the "run sdboot" command and bootargs that are configured into u-boot-xlnx.
They look right. Below is the tail of the boot message. I'm hoping someone will recognize some of those last few messages and point me in the right direction. The last three messages seem to be trying to tell me something. Is there a way to get more information?
Can you please share the complete log and are you trying to use the rootfs from mmcblk0p2 partition. I attach the putty. Then I do printenv in u-boot and finally run sdboot to start the kernel. I tried running those pre-built images by copying BOOT. BIN, image. The "boot" command starts the kernel with a ram filesystem and all the busybox pseudo commands.
I'm not really familiar with the image. I'm guessing that is a container format that holds the kernel, rootfs and device tree blob. I changed the bootargs as you suggested but the linux boot fails in exactly the same way as before. Sign In Help. Turn on suggestions.
