# kv260

The
[KV260](https://www.amd.com/en/products/system-on-modules/kria/k26/kv260-vision-starter-kit.html)
DUT can be automated using the [kv260 boards MIB](/hardware/mibs/kv260.md).


## Components

The following components are required to fully automate the board:

- [kv 260 boards MIB](/hardware/mibs/kv260.md)
- Short RJ45 network cable
- USB-A male to MicroUSB male cable
- Micro SD Card
- 2.5/5.5mm barrel jack to MIB 2-pin connector, wired centre positive
- NF-A4x10 FLX Premium Fan
- Fan heatsink


## Software

In order for the kv260 DUT to be easily testable by LAVA please refer to this repo:

https://github.com/wmamills/xilinx-lab-stuff


## Hardware modification

In order to automate recovery, the DUT hardware should be modified.

```{admonition} Hardware modification
:class: warning
The DUT will not be automatizable without this modification.
```

### Fan and Heatsink

We suggest this fan.

NF-A4x10 FLX Premium Fan
```

Connect it to the kv260 with the "3:2-pin Adaptor NA-AC2" as shown.

![Fan connect](/_images/kv260/fan-kv260-connect.jpg)

Connect the fan
```

### FWUEN button

A two-wires cable should be soldered around the FWUEN button.
This will be used to drive the value high or low to trigger recovery.

### Recovery

Connect the recovery wires cable to the KV260 MIB header labeled `FWUEN` as indicated above.

### Network

Connect the kv260 network interface to the LAA private network interface as indicated above.

### Power

The kv260 gets power from the 2.5/5.5mm barrel jack connected to the board and the `12V` header on the MIB.

### Serial

Connect a USB cable from the carrier board MicroUSB port to `USB` on the MIB as shown above.

### USB

Connect the LAA `USB OTG` port (front facing) to the kv260 USB-A socket shown in the picture above.

### SD Card

Please take an SD Card of at least 16Gb and format it. Then insert it in the SD card slot on the kv260 board.
