Re: [Announce] USB hostmode beta release

I located the script "mount.sh"

The code is very clean and elegant. It works great.

I found that what does not is to run the script when you press the button to "Hen" to mount unit.

Any suggestions?

Re: [Announce] USB hostmode beta release

Things turned out just as I indicastes.

Thank you.

Try to see if I can modify the script to run it to open the file browser to mount the partition.

Re: [Announce] USB hostmode beta release

This was posted in the n9 thread by jalyst, and I thought you guys should see it too. Look at what they've managed to do with USB hostmode!

Re: [Announce] USB hostmode beta release

By the way, since I started to use (properly) new, improved joerg_rw's booston, I have yet to see *any* (well, in fact, I hope to *not* see it ;P ) problem with enabling hostmode. It just work all the time, at first attempt, no matter what I connect.

I don't know if it's due to booston, or I just become skilled at timing while connecting - or both ;) - but I think it's worth reporting, anyway.

i'm suspecting booston, because i have the same situation: all works fine without any effort.

Re: [Announce] USB hostmode beta release

Thanks joerg, I'm keeping my thumbs for this. As side note, I would encourage you to re-consider Your opinion about BFS kernel - it is not some "new" project, popped out yesterday, but respected, long-term effort. You know I'm not coder, but I'm sure iDont got serious reasons for keeping it as separate project (while many BFS patches were already implemented in kernel-power, in meantime). You can check it here (pre-official-release discussion):

Re: [Announce] USB hostmode beta release

@joerg_rw

Some questions about jrbme in kernel:

* Should be jrbme written against upstream kernel or maemo? Or both?
* Should be jrbme upstreamed?
* If it should go to upstream, what about split code into more separated modules and use standard linux interfaces (instead all in one sysfs entry)? One for watchdog which use standard linux watchdog interface, one for bq27200 chip which use power_supply interface (that already exists), one for bq bq24150 chip (use power_supply to?), maybe one for twl-madc (BSI) and last for usb host mode + glue to work all together...
* How is usb host mode working on old Nokia N8x0 tablets? Is for swithing between host mode and pheripheral mode any standard linux sysfs interface?

* Full jrbme should be BME replecament. Do somebody know what all is BME doing and what from BME can we implement?

I think that kernel module(s) should be written for upstreaming, but backported into maemo kernel too. And I think module(s) should use standard linux interface (watchog, power_supply, ...) if it is possible.

Well, I wrote that "spec" without upstream in mind, but hoped to implement a clean platform agnostic interface that just deals with bq24150

basically that sounds OK, but see following comments:
The watchdog is in no way a watchdog like the ones known from standard linux and also found on maemo, I.E. it won't trigger a reboot of system. So I don't think it should get implemented with a similar semantics to those, rather my idea was to mostly hide away the wd details and let kernel handle the wd-tickling usually (set wd to "auto", after config of the other parameters been done).

bq27200 isn't included at all in this concept, it for sure should get its own "domain" (and already has, though the implementation is really problematic, see http://mg.pov.lt/maemo-irclog/%23mae...09-30T22:19:42 )

that's what my "spec" at http://maemo.cloud-7.de/bq24150-sysnode.spec.txt is all about. I will appreciate comments about how to improve this set of sysnodes, move it to other namespaces, whatever. It's just a 70% finished RFC (in genuine meaning of words) for now.

This would finally stay a userland task, though it had a way reduced set of duties compared to what bme does now. It however should care about BSI / twl-madc etc

it simply does "echo host >mode". Alas for N900 there are a *lot* of routines missing in kernel to make this work.

there's quite a number of obvious and not so obvious things bme does, I think I elaborated on that a bit in original "why jrbme is dead" post linked to in my first post of this subthread. Also speedevil and shadowjk will have some valuable info on that, please contact them on IRC. Main thing is the IPC that provides battery status info to hald-addon-bme, which can't go to kernel for obvious reasons. You'll either need to patch hald-addon-bme to directly read the sysnodes rather than do IPC chat to bme, or you implement that IPC into the userland part I mentioned above.

well, I hope I was clear enough about it in above comments, so you know I basically agree or don't care, except where noted otherwise (watchdog) :-)

post number ONE in this very thread:

To install:
Install hostmode-gui from -devel, the package depends on kernel-feature-usbhost, so it should be compatible with any kernel that provides this (in debian/control), kernel-power provides this, and therefore, if no other kernel that does provide it is supported, it will be installed.

The GUI now checks for API version instead of kernel version, with the latest API being 20101110, also in kernel-power.

Post #9 this very thread:

Quote:

Until Mohammad updates the info in #1: We are not shipping a dedicated hostmode kernel anymore with h-e-n GUI. You are supposed to install kernel-power v45 (or newer), which has hostmode patches integrated. Installing h-e-n won't do that for you. Please refer to kernel-power howto and readme and FAQ, for details on how to install and how to remove this non-stock kernel.

Though I doubt it will be any more visible when I quote it here than it was on the original posts :-S

ultra-terse howto: get charge.sh from ShadowJK, install so you can execute it.
do:
start H_E_N, select speed
only *now* apply external VBUS
*now* immediately click vboost in H_E_N
enum, mount, etc
now do boostoff; charge.sh

to end: kill charge.sh, then close H_E_N

could you please take a look at usbhostmode.diff and confirm (or not) that

Code:

+                if (machine_is_nokia_rx51()) {

+                        musb_platform_resume(musb);

+                        musb_set_vbus(musb, 0);

+ 

+                        devctl &= ~MUSB_DEVCTL_SESSION;

+                        musb_writeb(musb->mregs, MUSB_DEVCTL, devctl);

+ 

+                        musb_writeb(musb->mregs, MUSB_TESTMODE, 0);

+                }

is missing a call to musb_platform_suspend(musb); at the end of the block

why do you think so? aah wait, seems this is a code snippet called when disabling hostmode? then probably yes, should (maybe) fix the annoying increased-power-consumption problem after ending hostmode.

I still grin about musb_set_vbus(musb, 0); as it's a completely empty function - alas

I've already sent a patch to Pali for inclusion in next KP as it seems like correct fix for the above bugs. But don't expect me to be able to grok in a day or two a patch that was produced in 6 months as a result of combined work of 6-7 developers. That is why I need someone who is familiar with code to confirm.

Do you mean this or the other way round? My experience is that the reboot command causes poweroff (only); also (as you say), the device doesn't power up when charging.

Re: [Announce] USB hostmode beta release

I've been trying the charger.sh script, however whenever I execute it, the mounted media is unmounted, and cannot be accessed unless I close h-e-n/xterm and start again.

Steps:

connect standard nokia micro USB data cable to N900, three-way cable to this, then flash drive to one prong, charger UNPLUGGED to the other
open h-en, mount flash drive as high speed (successfully, Sandisk 16Gb)
open xterm, as root run "sh charger.sh"
plug in ac adaptor
code runs, phone starts charging as per xterm output (which mathces with Conky's details, not sure if Conky's readout is inaccurate during h-e-n)

After charger.sh is executed, the media is unmounted. Any ideas?

Not mean to be "picky", but boostoff (before executing charge.sh) would be also useful ;) Sure, it (probably) also works without doing so, but there is no point in keeping it, if You want power-saving, or charging as quickly as possible.

Re: [Announce] USB hostmode beta release

Managed to mount a 500Gb passport HDD today, that formerly wouldn't mount (insufficient power from the N900). Rather than use a powered hub to power the drive, and then a separate AC adaptor to charge my N900, I modified the AC adaptor to have three USB ports: original port, that will charge my N900 over the Y cable, and a pair of ports that act like a female-female adaptor for joining two male ends together. These pair of ports take +ve/-ve from the AC adaptor, so in one port you plug your media/peripheral to be powered, and the other port takes the data cable that goes to your N900 (the other part of the Y cable). See picture. Probably not the safest thing going, but I will be tidying it up.

@ hostmode script ( worklog )

until now ...
status area icon - ok . it is a stock icon, blue.
it is activated when an valid device is connected. tap on status area will show an text saying "Host mode active".
More informations and actions will be added later after the moment when the script is stable

switching ( guessing ) speed work almost well. it is based on dmesg output
there is multiple ways doing this but not all are reliable. after 300 tests...
first method
first starting as high speed then low then full.
reason :
most connected devices are usb sticks, on second place mouses or keyboards
for this method there is a problem for sensing low speed devices in high speed mode.
khubd daemon interfere with driver and is hard to put whole system in a stable state.
second method
started as full speed and watching dmesg messages switch the speed accordingly. the fastest method, only 2 steps
reason :
if an full speed device is connected it will work "instantly". high speed devices are detected also in full speed mode and dmesg output is useful
but there is a problem with low speed device in full speed mode and khubd go crazy. this will add 20 s for a stable state. more tests are needed in this mode
third method
start as low speed then full then high. the most stable method
reason:
low speed devices are detected "instantly"
high or full speed devices are detected well. so continuing as full speed, the "full"devices will work and "high" devices are properly signalized

khubd and g_file_storage make a lot of problems.
for khubd there is an workaround flushing all configs but add 20 s for each khubd error.
g_file_storage need a patch because in high speed mode when a low speed device is attached it will trigger "mass storage" "Pc suite" selection. this can be ignored but is annoying.

a preference can be set in the script for first tested speed

later or tomorrow an alpha variant will be posted

Re: [Announce] USB hostmode beta release

why is problem with autodetection usb speed? and it is possible to check if host usb device or charger is connected?
