Can someone clarify how SODIMM 81 is used at boot time for Torizon on Colibri iMX6D?
If the pin is left floating, will it prevent boot from the eMMC? The Aster carrier has a 100K pulldown to GND. Why? The schematic note says:
Compact Flash (CF) Card detect
PIN_81, pulled down to GND to diable CF
What does that mean exactly? What is the process/description of how this pin is used at boot?
