3359 Bootconfig pins
Added by Brian Compter over 11 years ago
Is there documentation on the J106 header on the 3359 dev kit?
The quick start guide has one line about setting pin 4 to boot from the SD card but that is it. I would have thought this would be in the dev kit datasheet but was unable to find it anywhere.

Am I correct that the pin setting controls where the ARM looks for UBoot?

You are correct that this information should be in the datasheet. In fact, there is an open issue here about it. The boot pins 0-11 are brought out to the header. Their configuration and use is documented in the AM335X TRM ( http://www.ti.com/lit/ug/spruh73g/spruh73g.pdf section 26 [26.1.5.2.1 in the Nov 2012 edition]).
Putting a jumper on sets that bit low, otherwise it is pulled high.
Hope this helps
cheers
