Prerequisites¶

Access to Antelope through Smart Mission Lab
Reference design loaded to SPI Flash memory (See Load reference design (Linux in SPI))

Steps¶

Connect to EGSE Host with Antelope board

my-machine$ ssh customer@egse-my-egse.egse.sml.lan
customer@egse-my-egse:~$

Start minicom to access DPU’s serial port

customer@egse-my-egse:~$ minicom -D /dev/sml/antelope-dpu-uart

Leave terminal with minicom connected and open another one. In new terminal connect to the same EGSE Host
```
my-machine$ ssh customer@egse-my-egse.egse.sml.lan
customer@egse-my-egse:~$
```

Power on Antelope board

customer@egse-my-egse:~$ sml power on
Powering on...Success

Power on DPU

customer@egse-my-egse:~$ sml dpu power on
Powering on...Success

Release DPU from reset

customer@egse-my-egse:~$ sml dpu reset off
Bringing DPU out of reset...Success
