WiFi and USB for pocketbeagle

no wifi - 4 stars ... RTL8188 module and small usb hub with usual suspects

adding some WiFi over USB to the pocketbeagle I got at MFNY17 :)

Quick googling seems to make FE1.1S a good choice for a controller.

  • getting started again for testing

    call this on a mac in your browser http://beaglebone.local/ - if you get the beagle page, it works! (connecting over usb that is)

    ssh debian@beaglebone.local 

    with password temppwd (you should change that)

    sudo iwlist wlan0 scan | grep ESSID

    shows you stuff if

    sudo iwconfig

    shows you stuff if


    shows you stuff

  • prototype works (kind of)

    My wifi and usb hub for the pocketbeagle kinda works now. Little mistake to fix with a bodge wire. @oshpark boards work fine :) I can scan wifi ssids but have trouble with setting up the connection.

    Seems like there aren't any capacitors needed for the crystal, although it seems unusual coming from every other chip I've used that needed a crystal. I've added 10pF like in #(One More) Raspberry Pi Zero USB Hub but doubt they're necessary. 

    Only one extra USB port has a plug, out of size restrictions etc. - a second one has the RTL8188 directly connected. Therefore only one LED is really necessary for the "connected" status. 

    Added a PRTR5V0U2X as ESD protection for the "external" USB port.

I see you are searching for reference designs - FE1.1s + USB wifi module combo is used in my #raspberry pi zero handheld computer 

  Are you sure? yes | no

I found my mistake already, had one pin pulled low instead of hig ;) works now, but will check against your design later :) thanks

@Michael Welling  @Jason Kridner  @Jason Kridner  Is there SDIO on the headers?   @ajlitt and @davedarko are interested

  Are you sure? yes | no

There is no SDIO broken out on the PocketBeagle except for the microSD card slot.

  Are you sure? yes | no

thanks for clearing that up, would have been great for an ESP12-F WiFi pocketcape.

  Are you sure? yes | no

ajlitt wrote 10/06/2017 at 22:42 point

I haven't looked, but did they bring out SDIO on any of the cape?  It would be a shame to waste the only USB host on networking like some other low cost SBC.

  Are you sure? yes | no

I'm working in an USB Hub chip (FE1.1S) as well, not sure about sdio, can't see it on but maybe Drew @oshpark  can say more? You're probably talking about doing the same like on #RPi WiFi ?

  Are you sure? yes | no

You read my mind...

I spent a few minutes looking at the pinout and the AM335x datasheet, and it doesn't look like MMC0-2 are represented as alt functions on any of them.  Kind of a shame, since the AM335x SoC has 3 SDIO interfaces.

  Are you sure? yes | no
