Re: IOIO and Beaglebone connection problems

[lightguide]

Sorry the firmware is 3.24 with bootloader 3.04.

Hello,

I recently bought an IOIO from sparkfun Firmware 3.04 (assumption) and I'm trying it with a Beaglebone running Jellybean of rowboat and with a TI eval kit running ICS. The Beaglebone and Ti eval kit can be connected with the PC with debug mode but not with the IOIO. Also, I have a Samsung Phone and it connects ok with the IOIO all the time. Any hint on how to connect with the beaglebone will be appreciated.

Thanks

Try the ioio hardware tester app on your Samsung. Then you don't have to assume the versions.

I assume you have the trim pot all the way to the right?

yes I have the trimpot clockwise all the way. I checked after with my phone; and the version is 3.24 with 3.04 boot loader I was exchanging threads with Ytai and he mentioned that if the USB port was presenting as an USB hub on the BB then it would not work.

I would like to confirm that?
based on the elinux.org BB website this it what they say:

http://elinux.org/BeagleBone

The mini-USB type-A OTG/device client-mode socket is multi-functional. In addition to providing an alternative source of power, it gives access to an on-board front-end two-port USB client-side hub. (This is not related to the separate host-mode USB socket described later). One port of the hub goes directly to the USB0 port of the TI AM3358/9 SoC, while the other port connects to a dual-port FTDI FT2232H USB-to-serial converter to provide board-to-external-host serial communications and/or JTAG debugging.

So I think is presenting as ahub but still not sure.

Thanks for the response

Yeah, I saw that conversation. It does look like that's a problem. In Linux, I would look at lsusb. I haven't used windows since xp and in xp you could tell from the device manager.

From your quote it indeed seems to be the problem. I'm not sure what it would involve getting hub support for IOIO. Last I checked, the USB host libraries from Microchip didn't support it, although it might be possible to add (unless there's some hardware limitation I'm unaware of).

Unfortunately, this is not currently on my roadmap, since it is quite a corner-case. I'm happy to consider patches if you want to attack it yourself.
