BeagleBone SUBARCTIC issue

Sometimes the Mighty BeagleBone may ask for a new, unknown driver named SUBARCTIC. His VID is 0451 and PID is 6141, at least in the case of a A6a board.

A simple search about this can lead to a bunch of different opinions but the truth seems to be that is appears only in Sitara’s bootloader mode, when he waits for some other debugging options, maybe something on the non-soldered P7 JTAG Connector.

The BeagleBone Subarctic QuickFix

So, BeagleBone is built to boot something from the SD Card… Inserting the Linux SD Card all works fine, the board get into linux boot sequence, the right devices (USB Serial Port, RNDIS Gadget… ) are showing up and the drivers are loading.

The quick fix: don’t search for a driver instead put the SD Card with software in the connector and cycle power.

Here is a USBView capture of the SUBARCTIC issue:
