Wish I was wrong, but AFAIK, it's simply not possible on N9. Tivoization is the catchword.
joerg_rw (father of H-E-N) once described it as "you can see the hardware parts, you just can't access them. It's like they're sealed in epoxy".

Who is Nokia? Is that a new company? :eek:

Re: USB Host Mode for Harmattan?
 
There is no "tivoization" problem as long as you are happy with the current open mode, which you really should be.

The lack of USB host is just because lack of time, because there's not much to investigate other than just merge the same changes that were done on the N900. We used to think that there would be an easier method on the N9, because gaia is used as PHY instead of using a separate chip like on the N900, but it seems that even correct triggering of the ID pin on the N9 driver is not enough to get the OTG state machine rolling. So the only choice left is doing the same that was done on the N900.

In forum.meego.com there was an excellent thread about this, I hope the information DocScrutinizer posted there is not lost forever...

How wayback machine archives the internet?? I mean the internet is so huge so how does it keep track of every site??

Luckily, I copied all from that to a word document ;)

Here is the plain-text version of that (was, unfortunately, not the complete thread) (I can upload somewhere the word doc, if someone wants, or in mail)

(Actually, that page, is still there http://web.archive.org/web/201110080...ead.php?t=4610 - but it seems to sometimes not show, guess it might disappear at some point)

H-E-N9 USB hostmode enabler N9

I succeeded in a first step towards USB host mode: finding out about charger chip and operating it in boost mode -> stable 5V supply to USB receptacle

I'll copy the following from http://talk.maemo.org/showthread.php...68#post1094568 and continue the h-e-n topic here (if only for not completely hijacking that infodump thread ;-D )

It's well understood that there are still massive obstacles regarding loading of kernel modules and also regarding aegis introduced restrictions at large.

Re: H-E-N9 USB hostmode enabler N9

WANTED:
proper datasheet / user manual for RENO TWL5031 aka TPS65951 (or even twl5030/4030 tps65950) with register descriptions

(to save your time, this http://www.ti.com/lit/ds/symlink/tps65950.pdf has no proper register descriptions, it's mainly just about electrical and mechanical properties of the chip, not about actual usage, programming, etc. I'm looking for a file >>170 pages/2MB, probably)

Is this document any good? It mentions registers:

this one mentions the register names at least, but obviously doesn't explain a bit about how the registers are "working"

This one is the *51 variant of the useless tps65950.pdf 171p electrical and mech sheet I linked to as an example of what doesn't help.

here's a datasheet for another similar chip that shows what I'm looking for: http://www.ti.com/lit/ug/swcu067a/swcu067a.pdf (see "2.3 USB Register Descriptions")

many thanks for the help so far, and please don't hesitate to post new findings as well :-)

Re: H-E-N9 USB hostmode enabler N9

Great to see some progress in this area! This is such a useful feature, I really wonder why couldn't Nokia implement it by default? Any why couldn't they put microUSB-A in there in the first place (like N8 has for example)?

Re: H-E-N9 USB hostmode enabler N9

Detected mayor hardware differences ¹) between N9 (according to schematics and deduction) vs N950 (according to deduction). Those hardware differences have direct impact on the way USB hostmode would work and render extensive tests on N950 relatively futile, as the results are not applicable to N9.

Quim, how's about some N9 for testing? (no nice display or anything needed, so some sorts of "broken" devices were completely sufficient, as long as core APE and charging and USB works [edit] preferably also working WLAN, for access via ssh :-) [/edit])

[edit2]
STILL WANTED: TPS65951 Technical Reference Manual (analog to http://www.ti.com/lit/ug/swcu050g/swcu050g.pdf TPS65950 version)
[/edit2]

Who knows, so many of their choices in the past 12mths have been an utter mystery.
Luckily we have people w/the skill-sets & willingness to help, & luckily Nokia's open to facilitating that.
Otherwise we'd be "up **** creek..."

Re: USB Host Mode for Harmattan?
 
Fairly excellent.

I did follow part of that discussion but not to the end as forum.meego.com was scrapped.
Now it would be nice time to start this again, conducting the further tests with N9.
