Never tried reducing the eth0 speed. We where able to reduce the USB speed by making code changes to the linux kernel. (that was fun) But in the end soldering the USB connectors and providing a better contact of the Ethernet port to the chassis fixed most issues. Also the beagle bone green

Hello William, Thank you for your reply. I didn't even notice your 'typo' until you mentioned it. :) Yeah, I understand what you are getting at. Thankfully, all AIN pin are not far under Sitara, so adding another trace doesn't look too difficult. David On Fri, Jun 9, 2017

realize AIN requires 1V8 maximum, hence the divider given the 3V3 input. I'd like to use AIN7 as general purpose ADC of thermistor. Kind Regards, David McRell -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google G

I suggest you call clock_gettime () twice with nothing between these calls. printf() is a complicated function that may interact with hardware, for example, a serial port or ethernet. The time required to do input or output may depend on the state of the hardware, or on the operation of a queu
