| 08:18 | topi` | rabeeh: was it you who designed the HB hardware? |
| 09:08 | rabeeh | topi`: yes |
| 09:09 | topi` | rabeeh: then you surely will understand how the component controlled by gpio 32 (1,0) is going to react to 0/1? |
| 09:09 | rabeeh | which component exaclty? |
| 09:09 | topi` | I checked the cmponents's spec sheet, but did not fully understand how it limits current when the _EN gets 0 or 1 |
| 09:10 | rabeeh | U22? or U9? |
| 09:10 | topi` | I can't remember. It's the current limiter chip hooked to the USB in HB |
| 09:10 | topi` | let me check |
| 09:10 | rabeeh | the USB current limiters; right? |
| 09:10 | rabeeh | we use MIC2026 (Micrel) current limiters |
| 09:11 | rabeeh | those are just outputs from the chip to enable/disable the port |
| 09:11 | rabeeh | once enabled then there is a current measurement inside MIC2026 that if exceeds 0.5A (in theory) it shuts down |
| 09:11 | rabeeh | in practice this 0.5A becomes 0.6A or 0.7A |
| 09:12 | rabeeh | the main idea behind USB current limiters is to prevent shorts and big current withdraw from a port |
| 09:12 | topi` | I just wonder why the device I'm trying to control with it (a stupid power socket) refuses to shut down |
| 09:12 | topi` | maybe there is a trickle of mA's |
| 09:12 | topi` | that is enough to keep the VBUS at +5v |
| 09:12 | topi` | or even close |
| 09:13 | rabeeh | is that device self powered? |
| 09:13 | rabeeh | or it's get all it's power from the HB VBUS? |
| 09:13 | topi` | it's a power socket, so you connect it to 230V socket. |
| 09:14 | rabeeh | maybe it's back powering the VBUS? |
| 09:14 | rabeeh | in that case it will never shut down |
| 09:14 | topi` | and you're supopposed to control it via a PC that, when shut down, will shut VBUS and that way (via a USB cable) signals the power socket sto shut down slave sockets |
| 09:14 | topi` | it works OK with a Windows laptop... |
| 09:14 | rabeeh | can you take measurements? |
| 09:14 | rabeeh | fluke? |
| 09:15 | topi` | I should measure it, but my measurement devices are crap |
| 09:15 | rabeeh | just the voltage out of the VBUS |
| 09:15 | topi` | next trick I'll try, is to make HB suspend and then use a timer interrupt to bring it back to life after like 1 hour |
| 09:15 | topi` | I'll ask jnettlet how to create such a timer interrupt |
| 09:16 | topi` | in case you're wondering, our house has hot water heating via an electrical socket and I want to time it so that during the cheapest hours, water is warmed |
| 09:16 | topi` | so I needed a 16A socket that can be USB controlled |
| 09:16 | topi` | 230V 16A |
| 09:17 | topi` | I realize a relay is what I need, but if I can just use bulk stuff you can buy from Amazon, and won't kill my house insurance, then I'm happy |
| 09:17 | topi` | and a HB is just the right device for home IoT :) |
| 09:18 | topi` | If I can get it to work, I can write a piece for hackaday.com :) |
| 09:20 | jnettlet | topi`, you can use rtcwake with the second rtc device. |
| 09:21 | jnettlet | in the current tree there are issues with controller the USB voltage regulators. I have a complete rework of that in my tree that I will actually be pushing later today. |
| 09:22 | topi` | jnettlet: i thought it was just a simple thing of issuing the right GPIOs, based on the schematics |
| 09:22 | jnettlet | topi`, not that simple because those GPIOs are assigned to regulators so the kernel won't let userspace have access to them. |
| 09:23 | jnettlet | I have included a patch that allows you to control the regulators themselves from userspace. |
| 09:23 | topi` | rabeeh: good luck with the 8040 board, I cannot wait to get mine :) |
| 09:23 | topi` | jnettlet: aha, that explains |
| 09:23 | jnettlet | or you need to remove the pin assignment from the regulator in the device-tree |
| 09:23 | topi` | I noticed that I was not able to control one of them (gpio86) at all |
| 09:23 | topi` | I'll try your patch when I get back home :) |
| 09:24 | topi` | that has to wait some, I'm now in a business trip to Helsinki |
| 09:24 | rabeeh | topi`: thx. |
| 09:24 | topi` | rabeeh: what's your experience of working with Marvell so far? |
| 09:25 | rabeeh | i'v worked for Marvell for 14 years :) |
| 09:25 | rabeeh | in general very good devices; really good devices mainly for networking and storage |
| 09:25 | topi` | hope it's not that same hate relationship we (Nokia) had with Texas Instruments :) |
| 09:25 | rabeeh | the performance you can squeeze from those device (again for networking and storage) is simply brilliant |
| 09:25 | topi` | well, TI did some good designs, and the docs were quite nice |
| 09:26 | rabeeh | but there are issues (as usual); especially in lead times |
| 09:26 | topi` | we don't live in a perfect world :) |
| 09:26 | rabeeh | robustness is really good; i have Clearfog devices up and running from the beginning of the year |
| 09:30 | Exaga | rabeeh: RESPECT! the clearfog has no equal in terms of technology <3 |
| 09:31 | rabeeh | hey Exaga |
| 09:31 | Exaga | good day :> |
| 09:31 | Exaga | hows things? |
| 09:31 | rabeeh | things are great |
| 09:32 | Exaga | excellent |
| 09:32 | rabeeh | i have now two kittens |
| 09:32 | Exaga | rabeeh: did you hear about the release of the Slackware ARM -current hard flot port? |
| 09:32 | Exaga | float* |
| 09:32 | Exag | 09:32 * Exaga purrrrrrrrs like a kitten for rabeeh :P |
| 09:33 | Exaga | i am a real cat lover |
| 09:33 | rabeeh | i haven't seen that link; have link? |
| 09:33 | rabeeh | i got the two kittens where they were 2 weeks old |
| 09:33 | rabeeh | and only in time they started to purr |
| 09:33 | Exaga | awwww |
| 09:33 | Exaga | link to the ftp site? |
| 09:34 | Exaga | ftp://ftp.arm.slackware.com/slackwarearm/slackwarearm-current/ |
| 09:34 | Exaga | the current version is the hard float, 14.2 is the soft float version |
| 09:34 | Exaga | it's all in the changelog ;) |
| 09:34 | Exaga | they are so cute when they're young |
| 09:34 | rabeeh | i was wondering if cats purr is something they are born with? or they do learn in time |
| 09:35 | Exaga | not sure but i guess it's like anything, you learn as you grow |
| 09:35 | Exaga | or your body changes |
| 09:46 | Exaga | it's a bank holiday in england today rabeeh, so i have the day off work :> |
| 09:46 | Exaga | weather is good (for a change) so I'm just going to take it easy |
| 20:26 | vpeter | Anyone maybe knows how to use curl to download translations from transifex? |
