How to build it
|
|
===============
|
|
|
|
Configure Buildroot:
|
|
|
|
$ make versal_vck190_defconfig
|
|
|
|
Compile everything and build the rootfs image:
|
|
|
|
$ make
|
|
|
|
Result of the build
|
|
-------------------
|
|
|
|
After building, you should get a tree like this:
|
|
|
|
output/images/
|
|
+-- boot.bin
|
|
+-- boot.vfat
|
|
+-- Image
|
|
+-- rootfs.ext2
|
|
+-- rootfs.ext4 -> rootfs.ext2
|
|
+-- sdcard.img
|
|
+-- system.dtb -> versal-vck190-rev1.1.dtb
|
|
`-- versal-vck190-rev1.1.dtb
|
|
|
|
How to write the SD card
|
|
========================
|
|
|
|
WARNING! This will destroy all the card content. Use with care!
|
|
|
|
The sdcard.img file is a complete bootable image ready to be written
|
|
on the boot medium. To install it, simply copy the image to an SD
|
|
card:
|
|
|
|
# dd if=output/images/sdcard.img of=/dev/sdX
|
|
|
|
Where 'sdX' is the device node of the SD.
|
|
|
|
Eject the SD card, insert it in the board, and power it up.
|
|
|
|
Support for other boards:
|
|
=========================
|
|
|
|
If you want to build a system for other boards based on the same SoC, and the
|
|
board is already supported by the upstream kernel, U-Boot, and
|
|
xilinx-prebuilt, you simply need to change the following Buildroot options:
|
|
|
|
- Kernel Device Tree file name (BR2_LINUX_KERNEL_INTREE_DTS_NAME)
|
|
- U-Boot (BR2_TARGET_UBOOT_CUSTOM_MAKEOPTS="DEVICE_TREE=<dts file name>")
|
|
- xilinx-prebuilt (BR2_TARGET_XILINX_PREBUILT_BOARD)
|
|
|
|
Custom versal board support:
|
|
|
|
To generate a boot.bin image, Versal boards require a PDI (Programmable Device
|
|
Image) generated by Xilinx Vivado which contains all the hardware specific
|
|
boot information, such as clock, MIO and DDR initializations as well as any
|
|
customizations in the programmable logic. Since this PDI can only be generated
|
|
by Xilinx Vivado, Buildroot needs access to the prebuilt image. The Buildroot
|
|
xilinx-prebuilt package has support for Versal XSA files exported from Xilinx
|
|
Vivado.
|
|
|
|
Using the option BR2_TARGET_XILINX_PREBUILT_VERSAL_XSA, Buildroot can obtain
|
|
the prebuilt PDI from the XSA file.
|
|
|
|
1) Start with a defconfig supported by Buildroot (e.g. VCK190)
|
|
make versal_vck190_defconfig
|
|
|
|
2) make menuconfig
|
|
Visit the following menu and enable BR2_TARGET_XILINX_PREBUILT_VERSAL_XSA
|
|
|
|
Bootloaders --->
|
|
xilinx-prebuilt --->
|
|
[*] download a prebuilt Versal XSA
|
|
|
|
3) Within the same menuconfig, configure location of XSA. It can be in the
|
|
local file system or downloadable from an https:// location.
|
|
|
|
Bootloaders --->
|
|
xilinx-prebuilt --->
|
|
(<path to XSA>) URL of custom XSA
|
|
|
|
4) make
|
|
|
|
The resulting output/images will contain a boot.bin that includes the custom
|
|
PDI file extracted from the Xilinx Vivado exported XSA file.
