FYI: Nikolaus pointed me at http://www.micron.com/products/multi...fullPart&366=3 - you see 4Gb aka 512MB RAM is maximum We might try to find a PoP with RAM only that maybe allows 1GB (8Gb) then - at the expense of nuking NAND and moving the NAND partitions to eMMC or sth. We need to check that. Another idea I might investigate further is to add some RAM on eMMC bus as a fast volatile alternative to flash. For fast swap ;-) cheers and thanks for your invaluable feedback jOERG
