Boot Commands for Linux Host Machine - 2024.2 English - UG1209

Check if the DFU can detect the USB target.

$ sudo dfu-util -l

The USB device should be enumerated with the vendor and product ID (03fd:0050). You should see something like the following message:

Found DFU: [03fd:0050] ver=0100, devnum=30, cfg=1, intf=0, alt=0, name="Xilinx DFU Downloader", serial="2A49876D9CC1AA4"

Download the BOOT.bin that was created in Creating Boot Images for USB Boot.

$ sudo dfu-util -d 03fd:0050 -D <USB_Boot_Image_Path>/Boot.bin

Verify from the Serial Terminal if FSBL has loaded successfully.

Download the usb_boot.bin. Before this, start another terminal session for the UART-1 serial console.

$ sudo dfu-util -d 03fd:0050 -D <USB_Boot_Image_Path>/usb_boot.bin

Check the UART 0 terminal and wait until U-Boot loads.

On the U-Boot prompt, press Enter to terminate autoboot. Verify from the UART1 console that the R5 application has also loaded successfully.

Run the following commands to set up the DFU environment in the U-Boot command line:

$ setenv loadaddr 0x10000000
$ setenv kernel_addr 0x10000000
$ setenv kernel_size 0x1e00000
$ setenv dfu_ram_info "setenv dfu_alt_info image.ub ram $kernel_addr
$kernel_size"

In the U-Boot console, start DFU_RAM to enable downloading Linux images:

U-boot\ run dfu_ram

Download the Linux image (image.ub) using the following command from the host machine terminal:

$ sudo dfu-util -d 03fd:0300 -D <PetaLinux_project>/images/linux/image.ub -a 0

Execute Ctrl+C on the U-Boot console to stop dfu_ram.

Run the bootm command from the U-Boot console.

U-boot\ bootm

Verify that Linux loads successfully on the target.
