## Alveo u55c platform/XRT installation
In `Ubuntu 22.04` and `Vitis 2024.1` environment, the required resource can be downloaded through the following links.
After downloading and extracting all three files, execute the installation one by one.
The downlaod URLs and the installation commands are as follows. 

### Download URLs

### Installation Command (Install in order)
```
cd ~/Desktop
sudo apt install ./xrt_202410.2.17.319_22.04-amd64-xrt.deb
sudo apt install ./xilinx-u55c-gen3x16-xdma-3-202210-1-dev_1-3514517_all.deb
sudo apt install ./xilinx-u55c-gen3x16-xdma-validate_3-3506150_all.deb
sudo apt install ./xilinx-sc-fw-u55_7.1.23-1.4097d53_all.deb
sudo apt install ./xilinx-cmc-u55_1.5.25-3395704_all.deb
sudo apt install ./xilinx-u55c-gen3x16-xdma-base_3-3494559_all.deb
```

### Bash Shell Setting
After installing the Vitis tools as mentioned previously, the files will be placed in the `/tools/Xilinx` directory in the root of the Linux system, which is different from the `/opt/Xilinx` directory specified in the documentation. Be sure to pay special attention when verifying the `source` path.

### Install Additional Packages
Download `opencl-headers` and `gcc-multilib` for building the project using the following commands:

```
sudo apt install opencl-headers
sudo apt install gcc-multilib
```

## Flashing the Card

### Check current status: use the xbmgmt tool to view the card status.
```
sudo /opt/xilinx/xrt/bin/xbmgmt examine
```
### Flash the firmware
```
sudo /opt/xilinx/xrt/bin/xbmgmt program --base --device <management BDF> --image xilinx_u55c_gen3x16_xdma_base_3
```
### Cold Reboot
```
sudo reboot
```

## Validation

### Commands for validation
```
source /opt/xilinx/xrt/setup.sh    # Set environment variables
xbutil examine                     # Check compute card status
xbutil validate                    # Execute self validation
```
or
### Commands for validation
```
sudo /opt/xilinx/xrt/bin/xbutil examine    # Check compute card status
sudo /opt/xilinx/xrt/bin/xbutil validate   # Execute self validation
```

## Before modify BIOS, GRUB, Linux HWE kernel setting

The validation will be error in the verify kernel case, need to modify BIOS, GRUB(firmware settings) and downgrade Linux kernel HWE version.

### Linux kernel HWE downgrade
Use the following command to install linux kernel 5.15.0-161-generic.
```
sudo apt install linux-generic linux-headers-generic
```
After download the linux kernel `5.15.0-161-generic`, needs to reboot and choose the `Advanced options for Ubuntu` & `Ubuntu, with Linux 5.15.0-161-generic` option to change the linux hardware kernel to `5.15.0-161-generic`(original `6.8`).

### GRUB settings (firmware settings)
Use the following command open the nano in terminal to modify GRUB settings.
```
sudo nano /etc/default/grub
```
And the GRUB settings modification is in the following images.

If your processor brand is Intel, the settings of GRUB_CMDLINE_LINUX_DEFAULT `amd_iommu=off` can be replaced by `intel_iommu=off`.
After modification of GRUB settings, use `Ctrl+O`and`Enter` to save and `Ctrl+X` to exit.
And need to update the GRUB settings and reboot to update the computer by following commands.
```
sudo update-grub
sudo reboot
```

### BIOS settings
Motherboard: MSI
Processor: AMD
For the MSI motherboard, press `Del` to open the BIOS settings.
Settings -> Advanced -> PCIe/PCI Sub-system Settings
1. Above 4G Decoding -> Enable
2. Re-Size BAR Support -> Disabled
3. PCI_E1 Gen Switch -> Gen3

OC(Overclocking) -> Advanced CPU Configuration -> AMD CBS -> IOMMU -> Disabled
After BIOS setting, press F10 to save and exit

### Reminder
After GRUB settings modication and reboot, when the computer is power on and open the GRUB List, needs to reselect the `Advanced options for Ubuntu` & `Ubuntu, with Linux 5.15.0-161-generic` option to change the linux hardware kernel to `5.15.0-161-generic`, or the GRUB will select the previous option your computer opened before.

## After modify BIOS, GRUB, Linux HWE kernel setting
