Hi.

I tried to follow the instructions in the wiki and I failed at the very last step because I simply don't know what to do

Step 3: Flash system image
Copy the hikey-snappy.img to HiKey, and then execute the following command to flash image:
sudo dd if=hikey-snappy.img of=/dev/sdc bs=32M
sync

How am I supposed to copy the file "to HiKey"? there is nothing there to boot from and I am stuck at this point.

Help is very much appreciated

thx

Dear dawiki:

  I am sorry to tell you that we made a mistake. We should flash the hikey-snappy.img to Micro SD card, not EMMC Flash.We have revised it.

tony_zhang

The ptable-linux.img, fip.bin, nvme.img and writable.img are flashed into emmc,while the root file system hikey-snappy.img are flashed into the sd card using the dd command.

thank you very much

I think I got it installed - however apart from a flashing green led (LED904) it does not do much for me

I don't see any output via hdmi and it behaves differently when turning it on with/without several cables attached (usb keyboard, hdmi, etc). Also the blinking light is rapidly speeding up while sometimes LED903 is (continuously) on

I read over at ubuntu pages that snappy-core needs a wired network connection on first boot in order to load stuff over the internet - I don't know if that is the reason I am stuck or if I did anything wron

Thx for feedback and the correction in the wiki btw

The beta developer version can not output from HDMI, it can only do from debug_uart or ssh. After you login into the system via debug_uart, you need firstly  configure the wifi network:

1. $ sudo vim /etc/network/interfaces.d/wlan0
   
2. allow-hotplug wlan0
   
3. iface wlan0 inet dhcp   
   
4. wpa-ssid MYSSID
   
5. wpa-psk XXXXXXXXX
   

Copy the Code

and the reboot the system, you can try to install a hello-word to test the snap system:

1. $ sudo snap install hello-world
   
2. $ hello-world.env
   

Copy the Code

Thanks for the clarification!

I don't have a usb-uart connector yet. I already looked into the discussion on the 96boards forum and found a reseller that I can use

I was wondering if there is a way to automatically setup the wlan0 interface in the provided image. As for the SSID and WPA pass - it would be cool to be able to set this up on the sd-card without having to boot once and access the system via UART. This would enable SSH access via WIFI for this particular board

You can try to insert the sd card to your PC, and try to use the PC to edit the file in SD card.
I did not try this, maybe it can work.
