Basic questions WP7104-G

IoT Modules WP Series

Hi,
I got the my new WP7104-G development kit today, and i have a few basic questions about it.

  1. Can i connect to the WP7104 a led/lcd screen and if i can, via which connection i can do it?
  2. The development apps done on external cpu(running on linux) or done on the WP7104-G directly?

Thank you.

Hiya,

Not directly - although you could plug a serial LCD into one of the UARTs and write code to talk to it. I’ve started this, but it’s not finished.

However, if you mean plug a ‘monitor’ into the WP7104 dev board (using VGA/DVI/HDMI) then the answer is no.

Dev has do be done on a linux host machine using the dev tools provided by SiWi. You don’t have to use Developer Studio to build your apps - you can simply write C code at the command line and use the toolchain GCC to compile to executable (I’ve done this and it works pretty well) - but it’s a lot easier to develop using Developer Studio and the Remote access tools provided. Especially if you are already used to using Eclipse (which is what Developer Studio is based on).

ciao, Dave

Hi Dave,
thank you for the answer.
I have one more question, the first thing i should do is to install this http://developer.sierrawireless.com/Resources/Resources/AirPrime/Tools/USB%20Driver%20Installer.aspx
driver? and then i should install Developer Studio 3.0.0?

thank you

Hi Yuri,

You’ll only need the windows drivers if you need to do a firmware update of the WP71.

You’ll need to download the Application Framework from Github and install it as per the instructions on the GitHub page. Once you’ve got the Application Framework installed, download DS3 for Linux and start playing.

I will advise you to follow the instructions to the letter - including using the correct Ubuntu distribution (12.04 LTS) and making sure that you have all the pre-requisite packages installed, or you’re going to get quite frustrated…

ciao, Dave

Dave,

thank you once again for you quick answer.
Is there a manual for how to do the Cross toolchain with wp7 on ubuntu 12.04?

Hi,
So i try to follow the http://developer.sierrawireless.com/Resources/Resources/Legato/GettingStarted.aspx manual
on the page 14:
*When i try to save the UART1 configuration on minicom it show me a message “cannot write”.

**When i try to run a ssh root@ command on the terminal it give me message “Connection refused”.

What can i do to resolve this issues?

thank you for help

Hi Yuri,

Did you run as root (i.e. use the sudo command?). Ubuntu us a bit finicky about permissions.

Try running minicom using the following:

sudo minicom

and likewise for ssh:

sudo ssh root@<ip>

Also note that the IP address of the Legato will change unless you manually set the MAC or IP address. Have a look at this post viewtopic.php?f=179&t=7718&p=31528 on the forum.

ciao, Dave

Hi dave,
I succeed with running minicom and ssh, thank you for that.
Back to toolchain:

I did it.

When I run $ sudo bin/legs
i got on the Terminal

DId i done something wrong here?

thank you

Hi Yuri,

Can you check to see that the toolchain actually exists at this location:

Check that the untar put things in the correct location as noted above. If not, move the tree in /opt/swi to the correct location and then re-run the legs script.

ciao, Dave

Hi Dave,
Thank you for toolchain tip.

When i trying to run ifconfig via minicom:

the terminal ask me for password and wouldn’t show me the target ip.
what could i do about it?

thank you
