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.
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.
