Quick start (NELK)

This section describes how to quick start NaonEVB-Mid-based system, provided that it is programmed according to NELK configuration.

1. connect the serial cable, provided with the board, to J17
2. connect this cable to PC COM port through a NULL-modem cable (not provided)
3. start your favourite terminal software on PC; communication parameters are:
   • baud rate: 115200 Bps
   • data bits: 8
   • stop bits: 1
   • parity: none
4. (optional) to connect the system to Ethernet LAN, please plug cable on connector J11
5. (optional) to connect the system to HDMI TV/LCD, please plug cable on connector J6
6. connect a 12Vcc power supply to J14 as shown in the following picture:

Once power has been applied, U-Boot bootloader will be executed and the following messages will be printed on serial console (please note that messages may vary due different U-Boot releases):

NAON#

These messages are printed by U-Boot, which has a serial console that allow basic interaction with the system. Please find more information in the U-Boot category page.

At the end of its boot sequence, U-Boot prints NAON# prompt and waits for user commands.

The default u-boot environment can be printed using the print command:

If you have the SD/MMC provided with the development kit, you can run the following command:

run spi_mmc

To start Linux (from on-board SPI NOR flash) and mount the development root file system (over SD/MMC).

If you have installed the Dave Virtual Development Kit, you can start the Virtual Machine and start Linux loading the kernel through tftp and mounting the NFS root file system with the following command:

run net_nfs

Please note that you need to modify some u-boot environment variables before running the net_nfs configuration. For further information, please refer to Configuration net_nfs.
