Feb 26 03:04:14 <fouric> upload repeated
Feb 26 03:04:47 <fouric> zmatt: it works
Feb 26 03:04:49 <fouric> IT WORKS
Feb 26 03:04:51 <fouric> THANK YOU
Feb 26 12:56:01 <zmatt> fouric: nm-applet is just a frontend for networkmanager... you should have restarted networkmanager itself to get it to notice you changed /etc/network/interfaces
Feb 26 12:56:04 <zmatt> :)
Feb 26 14:31:53 <kb1gtt> Can some one suggest how to get BBB UWN100 wifi drivers installed and functional on 3.8.13-xenomai-r83? More details / logs posted here https://groups.google.com/d/msg/beagleboard/KTF10-AEmpw/WpQUYdBFCQAJ
Feb 26 15:45:42 <Henke> Hello!
Feb 26 15:47:35 <henrikthomasson> Hello everyone
Feb 26 15:47:43 <henrikthomasson> Is there a way to reset the uEnv.txt file?
Feb 26 15:47:52 <henrikthomasson> factory setting
Feb 26 16:49:43 <zmatt> henrikthomasson: you can reflash the device, or grab an uEnv.txt from a stock image
Feb 26 17:04:13 <henrikthomasson> How do I grab it from a stock image?
Feb 26 17:04:45 <henrikthomasson> And I don't think I can reflash it, there is no code in the uEnv that let's me flash. I tried adding it
Feb 26 17:04:55 <henrikthomasson> It did not work for some reason
Feb 26 17:06:39 <zmatt> you can always reflash a beaglebone
Feb 26 17:06:54 <henrikthomasson> Sorry for being such a noob
Feb 26 17:07:01 <henrikthomasson> May I ask how you do that?
Feb 26 17:07:13 <zmatt> the only way to actually brick it is if you damage the hardware :)
Feb 26 17:07:28 <henrikthomasson> I have tried flashing it with various .img files but only one led blinks and it does that for a long long time
Feb 26 17:07:35 <henrikthomasson> They do not light up in sequence
Feb 26 17:07:51 <zmatt> does that led blink in a heartbeat pattern?
Feb 26 17:08:06 <henrikthomasson> like dunk-dunk=
Feb 26 17:08:07 <henrikthomasson> ?
Feb 26 17:08:08 <zmatt> . .    . .     . .
Feb 26 17:08:11 <henrikthomasson> yes!
Feb 26 17:09:20 <zmatt> that's simply a running beaglebone
Feb 26 17:09:30 <zmatt> i.e. it booted a system, it wasn't flashing
Feb 26 17:10:06 <henrikthomasson> hmmm
Feb 26 17:10:22 <henrikthomasson> Could it be that I am not allowed to use the eMMC?
Feb 26 17:10:40 <henrikthomasson> Because I hold the button at start up
Feb 26 17:11:04 <zmatt> be sure to hold down during power-on specifically
Feb 26 17:11:47 <zmatt> an easy to way verify you did it right: try it with no card inserted, then it shouldn't boot at all (only power led turns on)
Feb 26 17:12:14 <zmatt> if you then insert a card and press the reset button you know for sure it has booted from the card and not from eMMC
Feb 26 17:12:58 <zmatt> if that card is a flasher image, then it should proceed to flash the eMMC
Feb 26 17:13:25 <henrikthomasson> So, there is no card in it now
Feb 26 17:13:38 <henrikthomasson> There is debian installed on it
Feb 26 17:13:44 <zmatt> (note however that there are also "standalone" images which are meant to simply run from card.  these never touch eMMC)
Feb 26 17:13:47 <henrikthomasson> But I want to flash ubuntu on it
Feb 26 17:14:04 <zmatt> no idea in that case
Feb 26 17:14:17 <henrikthomasson> Then I understand!
Feb 26 17:14:24 <henrikthomasson> So some are only meant to be run of the sd card
Feb 26 17:17:06 <henrikthomasson> When I examine beagleboard as a device on my mac
Feb 26 17:17:16 <henrikthomasson> the uEnv.txt file does not have much content
Feb 26 17:17:39 <henrikthomasson> if I put a new system on an sd and boot from that. Will that change the content in uEnv.txt?
Feb 26 17:19:53 <zmatt> if you boot from SD you can mount the eMMC and modify the uEnv.txt there if you want to
Feb 26 17:20:04 <zmatt> to repair it or such
Feb 26 20:29:53 <jg> Hello, I just received my new BBBW.  Is there a console flasher version available for it?
Feb 26 20:30:24 <jg> For the newest test images (2-2017)
Feb 26 23:21:40 <fouric> zmatt: what is the correct sequence of things to do to debug network-booted baremetal BBB code using the flyswatter2?
Feb 26 23:22:01 <fouric> (er, do you use a hardware debugger of some sort for your baremetal hacking?)
Feb 27 00:08:31 <zmatt> ah, flyswatter2... I have one too but I ended up never using it as I realized the xds100v2 is simply better
Feb 27 00:10:11 <zmatt> I've never used halting debug all that much, and when I did I generally used Code Composer Studio
Feb 27 00:28:01 <fouric> zmatt: doesn't the xds100v2 only work with ccs?
Feb 27 00:28:09 <fouric> (as opposed to, say, openocd)
Feb 27 00:28:58 <zmatt> openocd supports both and other FT2232H-based jtag adapters in general
Feb 27 00:29:08 <zmatt> CCS otoh doesn't work with flyswatter2 :)
Feb 27 00:29:20 <fouric> ...and question: when uploading a binary to the bbb using xds100v2, is the processor reset?
Feb 27 00:29:24 <fouric> right right
Feb 27 00:29:37 * fouric doesn't care about ccs, though, would much rather use openocd
Feb 27 00:33:57 <fouric> ugh
Feb 27 00:34:08 <fouric> if i can't get the fs2 to work, i'm just going to try another platform
Feb 27 00:35:31 <zmatt> neither ccs nor openocd is great imho
Feb 27 00:35:44 <zmatt> certainly back then, ccs simply worked better with TI targets
Feb 27 00:38:11 <zmatt> jtag upload is tricky mostly because you want to reset the SoC to get a clean slate, and iirc neither CCS nor openocd will do this correctly for you out of the box
Feb 27 00:39:06 <zmatt> jtag upload is also quite slow
Feb 27 00:43:24 <fouric> ugh
Feb 27 00:45:34 <fouric> this just makes me want to find another platform more
Feb 27 00:46:17 * fouric goes back to studying
Feb 27 00:47:19 <zmatt> why?
Feb 27 00:47:31 <zmatt> what do you expect to be different on "another platform" ?
Feb 27 00:50:31 <zmatt> the AM335x is probably one of the friendlier SoCs for baremetal dev
Feb 27 01:02:26 <fouric> zmatt: i've seen someone at my university flash baremetal code onto a nucleo-f042k6 (cortex-m0 core) using a command-line tool and then debug it using gdb
Feb 27 01:02:52 <fouric> the board included a serial-to-usb chip
Feb 27 01:03:13 <fouric> ...so you could provide power to the board, a flashing interface, and a debugging interface all through a usb cable
Feb 27 01:04:07 <fouric> no network boot needed, and no fiddling around with openocd configs or having ccs crash on me every ten minutes
Feb 27 01:04:26 <fouric> obviously, the bbb is several orders of magnitude more powerful
Feb 27 01:04:31 <fouric> i would *much* rather use it
Feb 27 01:05:02 <fouric> ...but i haven't been able to load code using the flyswatter2 + openocd, only network boot
Feb 27 01:05:56 <fouric> ...which plays poorly with the flyswatter2 (i've been having the gdb interface fail when i reload code)
Feb 27 01:06:45 <fouric> (and it took several hours to set up, and i'm *still* not sure what i did right, meaning that i'll probably be in for another few hours of work to get the same setup on my laptop)
Feb 27 01:07:47 <zmatt> fouric: cortex-m0 is a microcontroller
Feb 27 01:07:51 <zmatt> that's a whole different story
Feb 27 01:08:16 <fouric> ...in terms of debugging n stuff?
Feb 27 01:08:22 <zmatt> yes
Feb 27 01:08:25 <fouric> ah
Feb 27 01:08:38 <fouric> then i guess i want to be doing microcontroller development
Feb 27 01:08:39 <zmatt> there openocd simply does whatever tiny bit of device init is needed
Feb 27 01:10:22 * fouric just wants rapid iteration and step-through debugging
Feb 27 01:12:05 <fouric> we'll see
Feb 27 01:12:17 <fouric> for now, i gotta study for my fourier analysis midterm, which is tomorrow
Feb 27 01:12:22 <fouric> no arm assembly for *me*
Feb 27 01:12:27 <fouric> :(
Feb 27 01:12:44 <zmatt> good luck!
Feb 27 01:12:55 <zmatt> I know I had rapid iteration working at some point
Feb 27 01:19:10 <zmatt> ok I'm zZ
