ABS: The guts of Android: ext4 vs yaffs2ABS: The guts of Android: ext4 vs yaffs2Posted Apr 29, 2011 16:48 UTC (Fri) by karim (subscriber, #114)In reply to: ABS: The guts of Android: ext4 vs yaffs2 by csimmonds Parent article: ABS: The guts of Android
Agreed. I've never thought about this as an ext4 vs. yaffs2 thing. But I am wondering if the shift to emmc is due to multi-core (as one would conclude if Ted's line of thought is followed) or due to the fact that hardware manufacturers just wanted their customers to be able to use standard filesystems on their devices (or the customers asking for it.) In all likeliness, the decision was made by hardware design guys ...

nand to eMMC - pin counts Posted Apr 29, 2011 22:01 UTC (Fri) by pflugstad (subscriber, #224) [Link]
I believe it's about pin counts. Bare nand requires a lot of pins. eMMC is essentially a serial interface, with variable width data path (8 bit max). So by going with eMMC, you reduce your required pin counts, which equals cheaper boards.
