Jun 23 04:16:32 <Wormo_> nerdboy, the interconnect allows the PRU to control certain peripherals instead of the A8, and access some shared memories, but it sounded like you were looking for a direct bus between PRU and A8
Jun 23 04:17:11 <nerdboy> that's rpmsg/other
Jun 23 04:17:34 <Wormo_> which is based on shared memory and interrupts, right?
Jun 23 04:17:46 <nerdboy> newest is
Jun 23 04:18:12 <nerdboy> less the v5 uses mailbox
Jun 23 04:18:51 <nerdboy> which is basically a dt patch afaik
Jun 23 04:19:06 <Wormo_> is mailbox what you meant? I may have misunderstood you then
Jun 23 04:19:28 <nerdboy> mailbox as in hardware/kernel interface
Jun 23 04:19:38 <nerdboy> that's about all i know...
Jun 23 04:20:00 <nerdboy> v5 switches from mailbox to interrupts
Jun 23 04:20:21 <nerdboy> *v5 of pru-software-support-package
Jun 23 04:20:45 <nerdboy> corresponding kernel/dt is 4.4.12-r30
Jun 23 04:21:39 <nerdboy> the ti dev gave the dt patch hash and said you could switch back and forth, essentially
Jun 23 04:25:39 <Wormo_> The driver probably checks which is registered
Jun 23 04:27:22 <Wormo_> the PRU firmware would probably not implement both mbox FIFOs and the interrupts however, since it has less resources to spare than the A8 running linux
Jun 23 04:27:48 <Wormo_> I'm just guessing on that part
Jun 23 04:29:04 <Wormo_> maybe compile-time switchable though

Jun 23 05:29:04 <nerdboy> is there another doc for config-pin?  or, what format is "pin" argument supposed to be?
Jun 23 05:40:57 <nerdboy> nm, grep through /sys was helpful
Jun 23 06:37:28 <Visaoni> nerdboy: don't the PRUs have some shared registers available without the interconnect? http://elinux.org/File:PRUSS.png <-- scratch pad
Jun 23 06:44:20 <Wormo_> yes small space but fast
Jun 23 06:45:05 <Wormo_> Visaoni: are you available 10 or 11am on friday for another hangout? alexhiam wants to join the fun next time
Jun 23 06:46:09 <Visaoni> that'd be fine. I'd probably prefer 11 but either is fine
Jun 23 06:46:25 <Wormo_> ok no problem both sounded available
Jun 23 07:12:14 <nerdboy> why can't i set usr3 blinky to pruout mode?
Jun 23 07:12:47 <nerdboy> is it dt/pinmuxing or not allowed at all?
Jun 23 07:13:06 * nerdboy swears at green dog...
Jun 23 07:21:20 <Wormo_> nerdboy: config-pin?
Jun 23 07:22:11 <nerdboy> query/set pin mode
Jun 23 07:22:59 <Wormo_> so what was the command you tried, for setting the pinmux?
Jun 23 07:23:50 <nerdboy> the one you're supposed to use
Jun 23 07:24:29 <nerdboy> the mode for usr leds comes back pruin but can't be pruout
Jun 23 07:24:57 <nerdboy> usr3 is emmc by default but i'm not using emmc, so...
Jun 23 07:25:12 <Wormo_> what was the specific command, so I can get oriented to what you're doing without being able to see for myself
Jun 23 07:25:30 <Visaoni> have you tried the other leds?
Jun 23 07:25:58 <nerdboy> i just switched to black
Jun 23 07:27:50 <nerdboy> and no, i only tried usr3 so far (it's the only one not in active use)
Jun 23 07:38:21 <nerdboy> it's "config-pin -a P9_24 gpio"
Jun 23 07:38:39 <nerdboy> sets it to gpio mode fine
Jun 23 07:40:51 <Wormo_> but 'out' instead of gpio won't work?
Jun 23 07:41:27 <nerdboy> pruout is not valid
Jun 23 07:41:33 <nerdboy> just pruin
Jun 23 07:41:35 <Wormo_> or 'hi' to start with high
Jun 23 07:41:49 <Wormo_> ok
Jun 23 07:43:53 <Wormo_> are you sure that pin can be pru output then?
Jun 23 07:44:03 <Wormo_> https://github.com/cdsteinkuehler/beaglebone-universal-io/blob/master/config-pin#L476
Jun 23 07:45:12 <Wormo_> might need to disable another peripheral to get a suitable pin
Jun 23 07:48:15 <Wormo_> check out the nice images
Jun 23 07:48:17 <Wormo_> http://www.embedded-things.com/bbb/beaglebone-black-pin-mux-spreadsheet/
Jun 23 07:48:26 <nerdboy> that's what i was thinking
Jun 23 07:48:50 <nerdboy> just not with default universal cape i guess?
Jun 23 07:49:22 <Wormo_> No I think it's hw limitation
Jun 23 07:49:53 <Wormo_> these spreadsheets were based on the table in the AM335x datasheet
Jun 23 08:04:06 <nerdboy> that doesn't say led anything...  is P9 pin number column same as config-pin number?
Jun 23 08:11:36 <Wormo_> yes I think so
Jun 23 08:12:08 <Wormo_> both should come from the datasheet for the SoC
Jun 23 08:21:49 <ZeekHuge> nerdboy: the leds down there, bottom right : https://github.com/ZeekHuge/BeagleScope/blob/master/docs/BeagleboneBlackP8HeaderTable.pdf
Jun 23 08:22:00 <ZeekHuge> *bottom left
Jun 23 08:43:21 <Wormo_> zeekhuge, none of the user led pins could be muxed writable by PRU, and that's why you hooked up external LED right?
Jun 23 09:10:12 <ZeekHuge> Wormo_: yep. And probably the universal cape is not touching them.
Jun 23 09:11:16 <ZeekHuge> actually IIRC the leds cant be controlled by the pru directly
Jun 23 09:11:58 <ZeekHuge> you will have to see the address of the leds and then write to it
Jun 23 09:12:24 <ZeekHuge> so, the pins are addressed out of the PRU-ICSS subsystem.
Jun 23 09:12:30 <ZeekHuge> Wormo: nerdboy ^
Jun 23 09:12:33 <ZeekHuge> in BBB
Jun 23 09:12:54 <ZeekHuge> yes **** IN BBB ***** dont know anything about green
Jun 23 09:21:46 <Visaoni> it's probably the same for green. I don't think much changed beyond the hdmi -> grove uart+i2c
Jun 23 09:21:58 <Visaoni> at least theoretically
Jun 23 09:23:00 <Visaoni> zeekhuge: for your pru examples, I see you have a deploy script setup for them. I don't see that in the pru-software-support-package stuff. where did it (or the stuff inside of it) come from?
Jun 23 09:25:54 <ZeekHuge> Visaoni: deploy script is just simple collection of commands that anyone would need to get the PRUs started, thats it, I would use those commands typing them by hand, so I just put them into the script. hence I am the author of the script.
Jun 23 09:26:06 <ZeekHuge> If its helpful +1 it :)
Jun 23 09:27:16 <ZeekHuge> though is still type each command. helps me to see what I am doing ..
Jun 23 09:29:42 <Visaoni> nice. in that case, anywhere in particular you found that told you to use those commands?
Jun 23 09:30:01 * nerdboy paints a big +1 on ZeekHuge's forehead
Jun 23 09:30:12 <nerdboy> scripts and makefiles Good
Jun 23 09:30:22 <ZeekHuge> ZeekHuge: nope.
Jun 23 09:30:26 <ZeekHuge> ahh ..
Jun 23 09:30:29 <ZeekHuge> Visaoni: nope
Jun 23 09:30:38 <ZeekHuge> thanks nerdboy :)
Jun 23 09:31:11 <ZeekHuge> though still just 2 starts to the repo :(
Jun 23 09:33:15 <ZeekHuge> btw +1 == +1star to the repo.
Jun 23 09:36:12 <Visaoni> Zeekhuge: figures... don't suppose you did anything special to get the pru firmware to uh, exist?
Jun 23 09:38:55 <ZeekHuge> Visaoni: didnt get that . you mean writing my own fw code ?
Jun 23 09:39:46 <Visaoni> Zeekhuge: no. I'm not finding am335x-pru[01]-fw in /lib/firmware
Jun 23 09:40:28 <ZeekHuge> Visaoni: what example you using ?
Jun 23 09:40:30 <Visaoni> only file with "pru" in that directory is uio_pruss_enable
Jun 23 09:40:48 <Visaoni> I'm looking at the pru_blinky deploy.sh
Jun 23 09:42:25 <ZeekHuge> https://github.com/ZeekHuge/BeagleScope/blob/master/examples/firmware_exmples/pru_blinky/deploy.sh#L60
Jun 23 09:42:33 <ZeekHuge> Visaoni: it should be there
Jun 23 09:42:45 <ZeekHuge> I just tested it.
Jun 23 09:43:02 <ZeekHuge> and working completely fine.
Jun 23 09:43:19 <Visaoni> oh. duh.
Jun 23 09:43:25 <ZeekHuge> I just executed the deploy script.
Jun 23 09:43:53 <Visaoni> cp. I'm so used to everything with /lib/firmware using echo somehow I managed to do that substitution in my head
Jun 23 09:44:41 <ZeekHuge> Visaoni: so working fine now ?
Jun 23 09:50:05 <Visaoni> Zeekhuge: not 100% sure yet. didn't setup the pins or anything. but nothing else broke verbosely, at least
Jun 23 09:50:29 <ZeekHuge> you are working on black or green ?
Jun 23 09:50:33 <Visaoni> green
Jun 23 09:50:47 <ZeekHuge> theres no need to do anything except executing the script
Jun 23 09:51:11 <ZeekHuge> so green has the 'config-pin' utility ?
Jun 23 09:51:19 <ZeekHuge> also whats the kernel ?
Jun 23 09:51:23 <ZeekHuge> Visaoni: ^^
Jun 23 09:51:43 <Visaoni> and I moved to the 4.4.12-ti-rt-r32 kernel, which I think made some changes that required the examples to be rewritten, which is why I didn't just clone and run your stuff
Jun 23 09:51:55 <Visaoni> Zeekhuge: yeah, green has config-pin
Jun 23 09:52:15 <ZeekHuge> pru_blinky should work anyway !
Jun 23 09:52:28 <ZeekHuge> even for 4.4.12-ti-rt-32
Jun 23 09:53:23 <Visaoni> oh, interesting. I'm just using the PRU-gpioToggle atm
Jun 23 10:07:45 <Visaoni> Zeekhuge: it does indeed work. awesome
Jun 23 10:08:55 <Visaoni> your readme was also helpful in getting the board to compile pru stuff too (previously got it going on the desktop with Code Composer)
Jun 23 10:12:30 <ZeekHuge> Visaoni: glad it helped :)
Jun 23 15:46:42 <chanakya_vc> hey bradfa, Did you get a chance to check out the driver?I made modifications to the firmware as well to make it work with the driver.
Jun 23 15:46:44 <chanakya_vc> mdp^^
Jun 23 16:49:29 <bradfa> ChanServ: I'm sorry :(  I've been completely swamped yesterday and today (only got 4 hours sleep last night)
Jun 23 16:49:46 <bradfa> ugh, autocomplete, that was meant for chanakya_vc
Jun 23 16:54:07 <nerdboy> you don't confess to ChanServ every morning?
Jun 23 16:54:48 <nerdboy> thought maybe that was some kind of irc ritual i hadn't seen yet...
Jun 23 17:40:33 <chanakya_vc> Np bradfa Please do check whenever you get the time. I might not be online tomorrow or on Saturday.If something important catches your eye, please mail me, I will come to the IRC at once.
Jun 23 17:41:33 <chanakya_vc> I definitely respond to your mail.Meanwhile I am working on the makefile and simultaneously also reading up on the spi subsystem
Jun 23 17:41:40 <chanakya_vc> mdp ^^
Jun 23 19:16:22 <chanakya_vc> Hey ZeekHuge ,there?
Jun 23 19:22:33 <ZeekHuge> chanakya_vc: hey ! kind of ..
Jun 23 19:23:01 <chanakya_vc> Completed your term eval questions?
Jun 23 19:23:04 <chanakya_vc> ZeekHuge, ^^
Jun 23 19:23:21 <ZeekHuge> yeah. after the meeting yesterday.
Jun 23 19:24:44 <ZeekHuge> was thinking of reminding it to you too ..
Jun 23 19:25:38 <ZeekHuge> and not to do like you did at times of proposal :P
Jun 23 19:25:48 <ZeekHuge> chanakya_vc: ^
Jun 23 19:26:57 <ZeekHuge> its simple .. just go ahead and do it. Will not take more than 10 minutes
Jun 23 19:27:17 <ZeekHuge> and do recheck. Its un-editable once submitted.
Jun 23 19:30:56 <chanakya_vc> ZeekHuge, I just did. :P
Jun 23 19:31:29 <chanakya_vc> And I was thinking that I would remind you
Jun 23 19:32:01 <chanakya_vc> Proposal was scary.Sometimes I think if my net suddenly went down in the last five minutes.
Jun 23 19:32:10 <chanakya_vc> Would have been a disaster :P
Jun 23 21:22:36 <amragaey> hi jkridner
