Apr 17 06:24:16 <Guest55391> Any way to flash BBB via usb disk?
Apr 17 06:26:19 <zmatt> http://pastebin.com/x5QzB18E
Apr 17 07:13:04 <Mausy5043> This worked on `wheezy`:
Apr 17 07:13:28 <Mausy5043> >>>  from bbio import SPI0
Apr 17 07:14:02 <Mausy5043> (python 2.7.9) on Linux bbone 4.1.15-ti-rt-r43 #1 SMP PREEMPT RT Thu Jan 21 20:13:58 UTC 2016 armv7l GNU/Linux
Apr 17 07:14:13 <Mausy5043> Now it produces:
Apr 17 07:14:19 <Mausy5043> Segmentation fault
Apr 17 07:23:35 <Mausy5043> I've notified graycatlabs over on github
Apr 17 07:24:05 <tbr> try the bone kernel instead of ti-rt
Apr 17 07:24:33 <Mausy5043> This is the one I got from beagleboard.org
Apr 17 07:24:40 <Mausy5043> You mean another one?
Apr 17 07:25:43 <Mausy5043> where would I get that?
Apr 17 07:27:57 <tbr> you install it from within the image
Apr 17 07:28:26 <Mausy5043> ???
Apr 17 07:28:33 <Mausy5043> I love some more details
Apr 17 07:28:34 <tbr> http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Kernel_Options
Apr 17 07:29:54 <Mausy5043> OK. the kernel update script or the apt-get route?
Apr 17 07:30:57 <tbr> I'd expect both to yield the same results
Apr 17 07:32:56 <Mausy5043> The kernel update script downgrades says:
Apr 17 07:32:58 <Mausy5043> info: you are running: [4.1.15-ti-rt-r43], latest is: [] updating...
Apr 17 07:33:08 <Mausy5043> and does nothing.
Apr 17 07:33:14 <Mausy5043> I'll try the apt-get
Apr 17 07:34:25 <Mausy5043> there's a lot of them
Apr 17 07:35:18 <Mausy5043> which one is considered stable?
Apr 17 07:36:00 <Mausy5043> Maybe best to use 4.1.15-bone18 ?
Apr 17 07:36:22 <tbr> try and find out, which one works for your use case
Apr 17 07:44:43 <Mausy5043> what does "rt" mean in 4.1.15-bone-rt-r18
Apr 17 07:44:53 <Mausy5043> realtime?
Apr 17 07:46:19 <tbr> yes, and unless you _really_ know how to write real-time applications, you won't need that
Apr 17 07:46:30 <Mausy5043> ;-) OK
Apr 17 07:47:10 <Mausy5043> thanks for the help. I'll try using linux-image-4.1.15-bone18
Apr 17 07:47:14 <Mausy5043> see how that goes
Apr 17 07:47:33 <tbr> if everything else fails, you can go back to 3.8
Apr 17 07:47:44 <Mausy5043> I was on 3.8
Apr 17 07:47:55 <tbr> your paste implied 4.1-ti-rt
Apr 17 07:48:10 <Mausy5043> before that (couple days ago)
Apr 17 07:48:32 <tbr> and it didn't work?
Apr 17 07:48:39 <Mausy5043> someone here suggested `jessie` was stable.
Apr 17 07:48:45 <tbr> it is
Apr 17 07:49:06 <tbr> that however doesn't mean that random guides and binaries "on the internet" will work out of the box with it
Apr 17 07:49:07 <Mausy5043> yeah well not the parts I'm trying to use
Apr 17 07:49:24 <Mausy5043> bonescript... no go
Apr 17 07:49:43 <Mausy5043> SPI nope
Apr 17 07:49:56 <Mausy5043> 1-wire :-(
Apr 17 07:50:04 <Mausy5043> ah well
Apr 17 07:50:07 <Mausy5043> nice puzzle
Apr 17 07:51:40 <tbr> if you run jessie with a 3.8 kernel, I'd expect /most/ of the legacy instructions and guides to work
Apr 17 07:51:56 <Mausy5043> Mmm. hadn't thought of that
Apr 17 07:52:05 <Mausy5043> I could try that too.
Apr 17 07:52:10 <Mausy5043> thanks for the suggestion
Apr 17 07:52:22 <tbr> I'd first try the bone 4.x kernel
Apr 17 07:52:32 <Mausy5043> Yeah installing now
Apr 17 09:31:19 <zmatt> SPI works fine in jessie
Apr 17 09:34:27 <zmatt> they also added gpio chip selects in, I think 4.4
Apr 17 09:36:31 <Guest55391> i have strange issue over usb_ether for BBB. when i power device with usb it doesnt get ip from beaglebone. but when i power with 5v adaptor and plig usb in it will. any opinion?
Apr 17 09:40:34 <zmatt> sounds odd
Apr 17 09:41:30 <zmatt> possibly the load of the BBB is causing the 5V top drop sufficiently to cause the USB PHY tot not consider it "session valid"
Apr 17 09:41:50 <zmatt> (but not enough for the board to shut down)
Apr 17 09:43:46 <zmatt> try powering up on usb, then plug in 5v adapter
Apr 17 09:44:58 <zmatt> or, if you have a voltmeter, check the voltage on vsys (aka sys_5v) relative to ground while powered solely via usb
Apr 17 09:45:41 <Guest55391> thanks zmatt i'll try
Apr 17 09:46:34 <zmatt> if you power up on usb, connect 5v adapter, and then manage to log in you can inspect the kernel logs to see what it complained about
Apr 17 09:46:57 <zmatt> but not sure if that will work, sometimes the usb driver can get confused... it may require removing usb and replugging it
Apr 17 09:47:17 <zmatt> alternatively, use ethernet or a serial debug cable to see what's going on
Apr 17 09:47:33 <zmatt> if vbus is too low it should complain loudly about that in the kernel log
Apr 17 09:48:09 <zmatt> annoyingly there's afaik no way to override that... I mean, it doesn't *need* a valid vbus to operate, it's just the peripheral being pedantic about it
Apr 17 09:50:59 <zmatt> also be sure to use the cable included with the BBB or a similar one that's short and of decent quality... I've noticed that longer cables result in noticable voltage drop when drawing a lot of power
Apr 17 10:03:51 <Guest55391> i also debugged with serial and i could see this message: The IP Adress for usb0 is: 192.168.7.2 but again my pc cant get ip address
Apr 17 10:04:21 <Guest55391> i'm using kernel v 3.14.58-ti
Apr 17 10:04:57 <Guest55391> with am335x-boneblack-bbb-exp-c.dtb
Apr 17 10:07:55 <zmatt> that's a weird ancient kernel
Apr 17 10:08:15 <zmatt> and I don't really recognize the name of the dtb either
Apr 17 10:08:36 <zmatt> ah, for chipsee lcd board?
Apr 17 10:09:08 <Guest55391> dtb is for chipsee expansion and kernel was latest stable (befor 4.x.x) ti
Apr 17 10:10:27 <Guest55391> kernel 4.x.x boot time is a disaster around 1min so i had to use lower version
Apr 17 10:10:49 <zmatt> ok, I haven't used a 3.x kernel in ages
Apr 17 10:11:12 <zmatt> but if connected via serial you can inspect the kernel logs to check for usb errors
Apr 17 10:11:31 <zmatt> (the message on the login prompt is uninformative since that ip is statically configured on the bbb)
Apr 17 10:13:03 <Guest55391> youre right. i should check kernel logs. and another thing is that the problem occur after full power off and on (when i reset sometime it will recognize usb)
Apr 17 10:15:19 <zmatt> the fact that's solved by powering via 5v adapter almost certainly means it's a vbus error
Apr 17 12:35:40 <zmatt> funny, TI is still releasing updates to the omap5 TRM
Apr 17 13:55:50 <tbr> the SoC that never existed ;)
Apr 17 14:04:00 <Geof> You can still buy an EVM for it:  http://www.ti.com/tool/omap5432-evm
Apr 17 14:26:51 <tbr> Geof: the infamous OMAP5432 uEVM aka Panda5
Apr 17 14:31:10 <Geof> We had a good run with OMAP.  I was sad when it ended.  I had left TI by then, but it was the end of an era.
Apr 17 14:32:37 <Geof> We had all the Nokia, all the Japan, many of the Moto phones.  We just missed Apple and Samsung.  But it was a big miss.  :-)
Apr 17 16:38:47 <ayjay> does anyone know if there is a basic electrical engineering topic channel?
Apr 17 16:39:09 * ayjay googled like a pro
Apr 17 16:39:36 <_av500_> https://www.google.de/#q=electrical+engineering+irc+channel
Apr 17 16:41:45 <ayjay> yeah i know it was a dumb question sometimes I think outloud with my fingers
Apr 17 16:42:01 <_av500_> not dumb
Apr 17 16:42:06 <_av500_> but I have no idea
Apr 17 16:42:14 <_av500_> hence the google results are all I can offer
Apr 17 16:42:24 <_av500_> the sparkfun one looks like it, no?
Apr 17 16:43:13 <ayjay> the winners seem to be #sparkfun and ##electronics, ##electrical is a graveyard

Apr 17 17:01:06 <jonasthomas> Hello... on debian linux for bbb I know leafpad is the texteditor is already installed.   Is there a gui filemanager installed also by chance?  (The reason I ask, is I'm hooked up by usb to my laptop and for what ever reason, sudo apt-get install doesn't seem to be working)
Apr 17 17:03:42 <zmatt> the gui images include a file manager yes.  also, the reason it's not working is because usb gives you access to the bbb, it does not give the bbb access to the internet
Apr 17 17:05:17 <jonasthomas> cool... what's the name of the file manager... (I figured that was the case with the access... I figure I should change the passwords and stuff, when I get to that point)
Apr 17 17:05:17 <zmatt> for that either plug in ethernet, or share your laptop's internet connection with the bbb and configure the bbb to use that
Apr 17 17:05:42 <zmatt> euh dunno it is not an icon or menu somewhere?  I absolutely never use the gui so I have no idea
Apr 17 17:06:05 <zmatt> I remember it has a filemanager because I deleted it while stripping an image, but I don't remember the name right away
Apr 17 17:07:43 <jonasthomas> I working with machinekit booting from a sd card...   I'm still a bit of a newb on this.. I'm ssh'ng from terminal
Apr 17 17:14:55 <jonasthomas> to answer my own question  pcmanfm    (google is a wonderfull thing)
