Robert Turns out what was in flash was dead, would not even boot. I may have booted from flash on this board once when I first purchased the board last fall. So I have no idea what happened to flash or when. So I downloaded the latest 08/31/2017 IOT image and converted it to a flasher image

Robert Interesting as all I did was download the latest image you posted on Beagleboard.org and burn an sd card with it. I expanded the file system and tried it out. Seems to me if booting from an sd card the eMMC boot loader should neve be run. I will give a try to killing the MLO file and I

There are two parts to this: getting the i2c-tools source package into your Android source tree and telling the build process to include that package for your device. Since i2c-tools isn't in the XML manifest for A4B, you'll have to manually grab the i2c-tool source and put it in the correct

[beagleboard] FAT partition on newer images

Older BBB had a very useful FAT partition when plugged in via USB. The FAT partition was also accessible directly on the SD card. However, I have tested some newer images and saw that some of them still mount the FAT partition but it's not physically present on the SD card anymore. How can I
