How to get the serial port to show up in Linux 64-bit for the 4343W AVN board?

[Anonymous]

I'm guessing I need a udev rule to get the serial port to show up.  Anyone able to do this?  I've tried on both Ubuntu 15.1 and Linux Mint 17.  Not USB ports show up in /dev

Here is the output from lsusb.  This is from Linux Mint 17.  The output from Ubuntu only include the first Broadcom device, not the second secure processor.

To clarify, the serial port I am talking about is the serial console port the would normally show up under /dev/ttyUSBx that prints the diagnostic/program output to a terminal such as with the snip.scan application.

Which BCM4343W Linux based partner module are you planning on using?

Not sure what you mean by "Linux based partner module."  I'm trying to use the BCM4343W-AVN board and use the SDK with a Linux host computer for development.

My mistake.  We have several partners working on Linux based 4343W offerings.  You are using a WICED based offering on a Linux based host.

The only evaluation boards I'm aware of for the 4343W are:

• BCM94343WWCD1_EVB - BCM94343WWCD1 SIP module mounted on a full-featured BCM94343WWCD1_EVB evaluation
• AES-EVB-BCM4343W-G - Avnet BCM4343W IoT Starter Kit

Perhaps someone from the applications team can respond with t-shooting direction for your Linux based host environment.

You can add the BCM4343W to your Linux UDEV configuration by using the steps and files described in this post:  1. Prepare your device — wubby 1.0 documentation.

Ignore the Wubby stuff, and just pay attention to the instructions at the bottom which tell you where to download the drivers file, unzip it, then do the following (with some of my edits to be sure perms are set right:

$ sudo cp ./99-bcm.rules /etc/udev/rules.d/99-bcm.rules
$ sudo mkdir -p /opt/bcm
$ sudo cp ./bcm.sh /opt/bcm/bcm.sh
$ sudo chmod 755 /opt/bcm/bcm.sh

You shouldn't have to reboot, just plug in your 4343W board, and when you do, two files should appear automatically:

• /dev/ttyUSB0 - the JTAG port
• /dev/ttyUSB1 - the serial console port

You can test this by connecting directly to the serial port like this:

screen /dev/ttyUSB1 115200

Then if you hit the reset button on the board, you should see the boot sequence messages on the terminal.
