Basically, yes. And now Tony Lindgren will receive a prototype next week to help out.
No other known issues are left so far.

So, the slow mux/emmc is now a feature and not a bug?

The guy from Ti I vaguely mentioned in an earlier post.Nice, more help!
Who is he?
Edit: okay not the Ti Guy, mixing him up with Tomi

It was determined that without the mux the eMMC was only slightly faster. So "reasonable tradeoff" is more appropriate.
Yep. There are always trade-offs in hardware. It just is important they're reasonable, and in this case, they are.
You would not notice any real speed difference in usage.

It was determined most would be happy with about 10 mb/s (or less I don't remember) slower emmc so everyone can keep the muxed MicroSD slot without a major and expensive redesign.
Barely a difference in speed at all really. In my opinion it was a very reasonable decision.

Still fresh, damnit!
I hope you're just being lazy with capitalisation there, and really mean 10MB/s, because 10Mb/s is about 1.25MB/s, and technically even with lower case m meaning milli rather than mega, 10mb/s would be about 0.000001164B/s (or a full byte every 10 days)
But 10MB/s beats the drive I'm running this OS out of, so I hope it's that after all.

No. This electrical analysis and simulation was unneccesarry. It was impropper setting in uboot.

Yeah it was just lazyness, MB is what I meant.I hope you're just being lazy with capitalisation there, and really mean 10MB/s, because 10Mb/s is about 1.25MB/s, and technically even with lower case m meaning milli rather than mega, 10mb/s would be about 0.000001164B/s (or a full byte every 10 days)

This just taught me a lot.
I was always worried and would write out Mega Bytes instead of saying MB, to be sure that me opposite knew what I meant and I never looked up the exact notation.
Now I don't have to. Cheers for that
I'm not interested in Pyra until the 4GB is stable and no known issues are left. I really want one. I might even wait to hear that a newer CPU module is in dev, since the shipping CPU is a couple years old now. I've been burned on portable electronics so many times, but Pyra seems like the real deal to me. At this point, I trust Pyra more than I trust Wacom (been burned twice by them abandoning products!).

Amnesia can help with that.

well i think they'll make the production boards with the new layout anyways? or maybe i missed something...

The benchmark numbers for the eMMC that were thrown around were actually between 70 and 103 MB/s. The theoretically max. speed is crippled with the mux, but random access is already way below the crippled max. speed in practice, so it's highly debatable if there is an actual loss here.

How so? I thought max speeds went down by less than 10MB/s as well.
