[beagleboard] Re: I2C Read with length in the first byte of the transaction

Well, if the SMBus Specification Version 2.0 Section "5.5.7 Block write/read" is goofy then, um, okay ... However, since this appears to be a standard part of SMBus, now I really do wish to ask "How do I do this with the Linux I2C drivers?" -- For more options, visit

can you use usb port(P3)? or is it necessary to use J1 to view boot log? On Thu, Feb 15, 2018 at 11:37 AM, Robert Nelson wrote: > On Thu, Feb 15, 2018 at 1:16 PM, grjjl wrote: > > We have been using a micro sd to flash a new image to a debian >

I am trying to implement the 1-Wire protocol to read a DS18B20 temperature sensor on the PocketBeagle. So far I have been able to correctly read the temperature on a BeagleBone Black (BBB) using the following guide:

[beagleboard] Using ROS (rosserial) on PocketBeagle

I'm brand new to using Ubuntu, PocketBeagles, and ROS (Robotic Operating System). My current task is to read Xbox controller data on one PocketBeagle and be able to receive it on another PocketBeagle. The transmission medium is a pair of XBee S2C's. So far, I have been able to use /dev/ttyO4

Don't know if the TI processor SDK (http://www.ti.com/tool/PROCESSOR-SDK-AM335X) for the BBB will run on the pocket beagle, but last-I checked the TI processor SDK follows the OE/Yocto paradigm. I apologize for forgetting the differences between Yocto and OE. The SDK contains canned build
