Power management on Beaglebone part 3-Battery cont.

  This is a follow on to my previous two posts Power managment on Beaglebone AM335x platform part 1 and Power management on Beaglebone part 2-Battery for the community IoT BSP at BeagleBone BSP. The first two parts I discussed the background of battery support and some of the hardware modifications that are needed for the BeagleBone Black platform. I also talked about the AM335x’s on chip analog to digital converter (A/D or ADC) and how it can be used to measure voltage signals like battery voltage. We developed an A/D converter driver and test program and integrated it into the BSP. The next step in the process is to pull it altogether by developing a battery driver. The battery driver will, of course, be dependent on the A/D driver so we must make sure the A/C driver is loaded first. We can do this by modifying the drivers “Order” setting. For example here are the ADC registry setting: IF BSP_AM33X_ADC [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\ADC1]     "Prefix"="AD ...

You also have the option to create an offline layout. All fine and good so far but then comes the gotcha. It will stall asking for a SharedSource component.   You can try clicking the “Allow downloading for all files.” but it will not work and it ...
