Not sure if it makes sense or not, but the standard scripts do check for a board-specific syslinux.conf before falling back to the generic one:

infix/board/common/uboot/scripts/ixbootslot.sh

Lines 37 to 41 in 0328700

	for conf in "${board}-syslinux.conf syslinux.conf"; do
	if test -e blkmap ${blkmapnum} /boot/syslinux/${conf}; then
	sysboot blkmap ${blkmapnum} any ${scriptaddr} /boot/syslinux/${conf}
	fi
	done

It is still the same board SD/eMMC. Both are bananapi-r3. But I do not see any need for it now anyway.

Made it work this morning. But the experience was horrifying! 😨 We just have to improve the UX on this one .. or at least fix up the genimage.cfg.in and mkimage.sh tooling to create ready-made emmc image, because just that took me an hour of getting stuck before I got it working.
