May 27 15:26:51 anujdeshpande: I want to access GPIOs using mmap May 27 15:27:26 for that I think I have to set proper register mask in proper bank May 27 15:31:54 i think there was an article by alexanderhiam on that May 27 15:31:58 but that was with python May 27 15:32:19 http://graycat.io/tutorials/beaglebone-io-using-python-mmap/ May 27 15:32:41 * karki_ was about to paste that link :p May 27 15:33:03 but that’s quite old May 27 15:35:05 buenas, todos May 27 15:35:07 ankur: also https://github.com/chiragnagpal/beaglebone_mmap i think i know this guy. he’s a local May 27 15:37:00 anujdeshpande: how to calculate or find address of registers? May 27 15:37:21 have you downloaded that huge TI PDF for am335x? May 27 15:37:33 ya have it May 27 15:40:29 #define GPIO_DATA_OUT_REG 0x13C May 27 15:40:37 #define GPIO_DATA_IN_REG 0x138 May 27 15:40:44 #define GPIO_OE_REG 0x134 May 27 15:40:51 what does these mean?

May 27 15:47:10 you’ll need the offsets to calculate the values ankur, those you can find on page 4632 of the manual May 27 15:48:02 for example setdataout has offset = 194h, and so on. May 27 15:48:11 DiegoTc: how does it go with the git patch? May 27 15:48:37 I didn't worked on that yesterday. I have a cold I feel completely useless May 27 15:48:46 I have that today May 27 15:49:15 about the BBUI, I will tried to see jkridner code this week May 27 15:49:23 to see if I can help you with that May 27 15:49:41 offset just being the GPIOx_SET_DATA_OUT absolute address minus the start of the GPIOx module registers May 27 15:49:53 DiegoTc: ok, great. that's fine with me May 27 15:50:07 DiegoTc: ebadawy: if you need help I might be able to spend some time on it May 27 15:50:18 i.e. the set data out registers are 194h past the start of each module's registes May 27 15:51:45 moto-timo: I will do May 27 15:52:05 I have only use git with a team of two or three people May 27 15:52:12 that's quite new what I'm going to do May 27 15:54:29 DiegoTc: welcome to open source :) May 27 15:54:46 DiegoTc: git with thousands of committers May 27 15:54:47 <_av500_> 5min to 5min May 27 15:55:01 hahaha May 27 15:55:02 moto-timo: Lol for this one :D May 27 16:00:27 hi _av500_ May 27 16:01:44 <_av500_> 4min May 27 16:01:46 <_av500_> hi jkridner May 27 16:03:37 <_av500_> 2min May 27 16:03:56 yo May 27 16:03:58 hello all !

May 27 19:55:14 jkridner: how is pinmux set in bonescript? May 27 19:55:41 ankur: typically, but not always, it creates a .dtbo and loads it. May 27 19:55:52 ankur: I'm trying to migrate to using cape-universal... May 27 19:56:13 if it detects cape-universal on version 0.2.5, it'll use the pinmux helpers. May 27 19:56:30 ideally, it would check for a pinmux helper for each pin. May 27 19:56:56 and only load a created overlay for that pin if cape-universal isn't loaded and won't load. May 27 19:57:30 whats the difference if pinmux is done using memory map May 27 20:05:12 better to notify the kernel. May 27 21:02:42 ankur: sort of May 27 21:06:21 alexanderhiam: did you use memory map to setup pinmux in PyBBIO? May 27 21:09:32 DiegoTc: if i can make, you have to help me find a cool hat May 27 21:10:06 ankur: you can't write to the control module registers (including the pin multiplexers) from user space May 27 21:10:20 PyBBIO does it with Device Tree overlays May 27 21:10:58 PyBBIO doesn't use mmap at all anymore, everything goes through kernel drivers May 27 21:12:48 alexanderhiam: There is a file for each external pin found in /sys/kernel/debug/omap_mux/. Writing to these files tells a driver to configure the pin multiplexers as desired. ?? May 27 21:13:57 ankur: that was on the BeagleBone white May 27 21:14:28 yeah, omap_mux was part of the TI 3.2 kernel. May 27 21:14:30 since the 3.8 kernels on the BealgeBone Black that kernel driver is no longer there and it has to be done through the Device Tree May 27 21:14:39 never made it upstream or to newer kernels. May 27 21:14:57 you can get it on Black, but you'd be the only one on it. May 27 21:15:05 it made life too easy ;) May 27 21:15:05 feel free to forward port it May 27 21:15:12 I have it on my black ;) May 27 21:16:23 for PyBBIO I thought it made sense to support the stock kernel without any additional modules May 27 21:18:35 nerdboy: I will begin with that May 27 21:18:42 will try to contact Victor from El Salvador May 27 21:19:26 this way, I can have you and Victor May 27 21:19:44 as part of the Gentoo Foundation May 27 21:24:57 looks like we can be speaker #2 and #3 May 27 21:25:09 is the one guy all you have right now? May 27 21:26:47 nerdboy: nop, Guillermo Movia the community Manager of Mozilla for LA is comming May 27 21:27:00 Alexandre Oliva from red hat is coming May 27 21:27:39 DiegoTc: check with some of the guys from Intel in Guadalajara (Ben Esquivel comes to mind) May 27 21:28:10 moto-timo: do you have the email from him? May 27 21:28:30 DiegoTc: also, the National Instruments guys (Alejandro de Castillo comes to mind) May 27 21:28:37 They're both on my google+ May 27 21:28:49 great guys, met them through OpenEmbedded/Yocto Project May 27 21:30:13 moto-timo: your name on g+? May 27 21:30:32 Tim Orling (i guess) May 27 21:30:57 alejandro.delcastill@gmail.com May 27 21:36:18 benjamin.esquivel@linux.intel.com May 27 21:36:48 hopefully they don't mind hearing from you :) May 27 21:36:57 moto-timo: can I copy you on this email May 27 21:36:58 ? May 27 21:37:24 absolutely ticotimo@gmail.com May 27 21:45:55 * moto-timo afk for 15 minutes May 28 02:21:24 ds2: I currently have a 10uf ceramic bypassing the boost conv **** ENDING LOGGING AT Thu May 28 02:59:58 2015
