rev c1 2nd spin or rev c2 suggestion

Guess hw mods for C1 are too late now.

However after reading http://www.elinux.org/BeagleBoard#OTG I thought
it would be nice if a next generation of boards would have the
possibility to place a jumper to shortcircuit the two pens that define
host or slave mode.

There is not a jumper, but there are two closely placed pads that will allow solder to be applied for this function. There was not enough room to add the jumper. In addition, with the USB Host port being provided, the need to make the OTG port a host port is greatly diminished.

Gerald,

Are you referring to the points that are mentiond at the wiki or are
you referring to other pads (and if so which one).
Part of the rationale for my request is that I am not too happy
soldering and that soldering is less reversible than a jumper is. Then
again with a working host port, the need to drive this port in host
mode is probably less required.

Hi Frans,

AFAIK there are no other test point available - (Just checked the latest B6
layout). Only other option: You can access the signal at the R1 resistor in
case you want but I think this would require even better soldering skills,
wherefore I won't recommend trying this :slight_smile:

However please remember that pin 5 is GND, and it's therefore really only
pin 4 which might cause some real trouble :slight_smile:

Last option is as Dirk suggested to rework the cable instead, which might be
easier - or at least not that destructive in case of failure :slight_smile:

Best regards - Good luck

These are new pads that I am referring to on the upcoming rev C version of the board. They are very close together, so it is very easy to solder them, as no parts are involved. But, as I said, the need for grounding this pin is lessened due to the addition of the host port on the Rev C.

Gerald

Gerald, I agree that in rev C the need is less, so a jumper seems
overkill.

Søren, good info, guess there is a better place to get ground from.
I think I can find someone with good soldering skills to run a wire
from pin 4, probably add a small switch to make it controllable.
(or just run a wire from 4 to 5 allowing it to be cut if desired),
That at least makes the solution less permanent (which was the problem
I had with the wiki solution).
I will update the wiki.

Frans.
