I'm not sure about that. Jan said before that it's only driven high after
loading the PWM driver, and the processor datasheet shows ball T10 (P8_13)
as driven low during/after reset.
Jan, not ideal, but to disable the output sooner you could load the overlay
through cape manager, and then
Hi Marco,
I just enabled can0 using kernel 3.14.25-ti-r37 and the dtb-rebuilder (it's
showing up with ifconfig -a, I haven't tested it further). It was pretty
painless. Is there a strong reason not to use this kernel? If not a
simple apt-get install linux-image-3.14.25-ti-r37 could be all you
Hi,
I think that's from an old SRM. Section 8.1.2 of the current (rev C.1) BBB
SRM shows different pins and there is note of a correction in the change
history..

Good idea, thanks. I will try it. I think the positive pulse will be so
short that it will not be able to move the motor.
