**** BEGIN LOGGING AT Tue Aug 15 03:00:02 2017 Aug 15 03:14:06 hmm, it should be 0x76 indeed Aug 15 03:16:08 kinda weird they didn't connect it to i2c0 Aug 15 03:17:50 but, "issue the echo to load the driver" ? it sounds very odd to me if any such action is needed in the first place Aug 15 03:18:41 I tried 0x76 as well by grounding the cs pin Aug 15 03:19:18 the weird thing is, sometimes i2cdetect -y -r 1 gives different results each run Aug 15 03:19:25 ohh, sorry, you're talking about an external bmp280 Aug 15 03:19:40 I assumed you were using a bb blue, which also has a bmp280 Aug 15 03:19:45 don't use i2cdetect Aug 15 03:19:50 yeah, the weather click module Aug 15 03:19:53 oh ok Aug 15 03:20:01 it crashed the bbb Aug 15 03:20:35 have to physically reboot after most of the i2c detect runs Aug 15 03:20:43 "WARNING This program can confuse your I2C bus, cause data loss and worse!" -- i2cdetect manpage Aug 15 03:20:53 yeah I read that :) Aug 15 03:21:01 expected behavior Aug 15 03:21:03 i2c is not a discoverable bus Aug 15 03:21:11 right Aug 15 03:21:29 although it still shouldn't crash the bbb Aug 15 03:21:43 it might crash the bmp280 though Aug 15 03:22:14 I am re-applying power to the bmp each time though Aug 15 03:22:27 I can see on my scope that SDA comes to live again when I do that Aug 15 03:24:41 uhh, based on the datasheet it looks a bad idea to have it unpowered while the i2c bus is still being pulled up Aug 15 03:25:02 speaking of which, do you have adequate pull-ups on the i2c bus? Aug 15 03:26:14 so show-pins gives "up" for P9.19 and P9.20 Aug 15 03:26:45 no I mean real pull-up resistors, not the flimsy internal pull-ups of the am335x Aug 15 03:27:02 those are just to keep unconnected pins from floating Aug 15 03:27:15 hm oh well then let me get right into this, that was also a consideration of mine Aug 15 03:27:20 great will try thanks Aug 15 03:27:24 for i2c you need 4.7 k or so Aug 15 03:27:42 yeah I saw guides on the web just wasnt sure if the internal ones do the job already Aug 15 03:27:50 not the 50-150 k that the internal ones are (iirc) Aug 15 03:27:57 cool will try Aug 15 03:28:12 and I suggest avoiding "hotplugging" like you have been Aug 15 03:28:19 ok! Aug 15 03:28:22 connect it properly while the bbb is powered down Aug 15 05:21:21 or: mount -t ext4 /dev/mmcblk0p1 /home/debian/mmcblk0 Aug 15 05:21:36 sorry wrong line from history Aug 15 07:26:51 what is x15? Aug 15 07:42:21 one more than x14 Aug 15 07:51:29 and finally shipping apparently Aug 15 07:55:30 surprisingly, yes Aug 15 07:56:18 any idea what the differences between our early boards and their SoC and this new stepping on revC is? Aug 15 08:09:18 hi everybody, i hope it is going fine. I have a question concerning QT, has anybody succedded in instaalling qt kit on Beagle bone black. I know it is not a pure BB problem but why not asking you this? Aug 15 08:12:33 toto_ [5139b71f@gateway/web/freenode/ip.81.57.183.31] has joined #beagle [10:09] hi everybody, i hope it is going fine. I have a question concerning QT, has anybody succedded in instaalling qt kit on Beagle bone black. I know it is not a pure BB problem but why not asking you this? Aug 15 08:19:42 hi? Aug 15 08:32:50 Hi everybody Aug 15 08:33:25 are you familiar with QT on BB? Aug 15 09:07:19 desjardin: that will depend entirely on the Linux distribution that you are running on the BBB Aug 15 09:17:23 i am running jessie Aug 15 09:18:02 jessie 8.7:Linux beaglebone 4.4.54-ti-r93 Aug 15 09:22:13 are you here Aug 15 09:31:43 so then the primary option you have is to use Qt from the debian repositories, which is probably a bit dated Aug 15 09:33:02 yes, i am using linaro compiler witn a 4.8 qt repository, it is weird that we have to rebuild the QT kit. Aug 15 09:35:09 debian has 5.3 in jessie, no need for necrophilia Aug 15 09:40:10 5.7.1 if you upgrade to stretch Aug 15 09:40:51 5.9.1 in experimental (not sure if I'd go there though, would depend on my stability/reliability requirements towards OS and Qt) Aug 15 09:45:40 What do you mean by debian has 5.3 in jessie? 5.3 of what? Aug 15 09:49:32 https://packages.debian.org/search?keywords=qt5-default Aug 15 09:49:35 Qt Aug 15 09:49:39 i am looking for a good tuto to install qt on jessie of beagle bone latest version, Aug 15 09:50:12 tbr: QT? is there any API to start QT ? Aug 15 09:51:01 Qt is not an app, so you don't "start" it Aug 15 09:51:17 generic debian jessie Qt instructions should mostly apply Aug 15 09:51:36 also will depend on what you're actually implementing Aug 15 09:54:31 i am willing to implement an interface which shows graphical stuffs like text box, edit box, small images, to see a sort of TV screen on the screen Aug 15 09:56:04 so HDMI output. Start with the debian desktop image and run the app as fullscreen. Aug 15 09:57:03 beyond that it's identical development to directly on desktop. Just that you deploy e.g. over ssh or such. Refer to QtCreator documentation for details, if you want to use that. Aug 15 09:57:25 Also you should be able to get help from the Qt community channels on freenode IRC Aug 15 09:57:51 as nothing of this is beagle specific. It sounds like a pure Qt app Aug 15 10:01:04 ok thank you it helps Aug 15 11:04:29 Hi, I have deleted u-boot with "mmc erase 0 0x88000000" and now all I see when I turn my BBB on i "CCCCCC". Is there any way to recover from this? Aug 15 11:05:02 I have tried with an SD card and pressing the USER button but the same thing happens. Aug 15 11:16:29 Ooops Aug 15 11:16:57 you will have to power UP the BBB with the uSD plugged in whilst HOLDING The Boot button (next to the card slot) Aug 15 11:42:31 Thanks, I have done that already and I still get the same CCCCC. Any other option? Aug 15 11:44:16 how did you prepare the SD card? Aug 15 11:45:49 I have one built with Yocto and one with the latest iot image, that works in a different BBB Aug 15 11:46:25 Is the USER button exposed in a header? maybe my button is broken? Aug 15 11:49:50 the button next to the SD slot Aug 15 11:50:08 and only plug in power once you hold it down Aug 15 11:50:16 the power led goes on for a few milliseconds and then off again... not a good sign. Aug 15 11:50:20 this includes USB, obviously Aug 15 11:50:48 Yes, I have tried pressing the button next to the SD card and then powering the BBB on, but it didn't start from the SD card Aug 15 11:51:11 are you 100% sure that the card boots in another BBB? Aug 15 11:51:28 I'll try again, give me aminute Aug 15 11:51:32 because in most cases it's an invalid card Aug 15 11:51:47 something like image written to the partition, not the raw device Aug 15 11:55:26 Yes, the SD card it's OK in a different BBB, so is the power cable and the serial connection. It doesn't even go into u-boot in the faulty BBB. Aug 15 11:56:02 Maybe I have deleted the flashed u-boot and MLO? Aug 15 12:02:05 either your board or its SD slot seem broken, if the card works in another device Aug 15 12:02:41 actually with MLO removed from eMMC it should always boot from SD, also without button press IIRC Aug 15 12:03:37 Thanks for your help. I think the board is broken, the power led doesn't stay on anymore :( Aug 15 12:04:27 if you still see CCCC then the CPU isn't dead Aug 15 12:06:01 I don't see CCCC now. and I haven't changed anything. just trying to power on/off several times and suddenly the power led has given up. Jack or usb power can't keep it on Aug 15 12:14:50 right, if CCC stopped coming and the power led dies, then the SoC or TPM died Aug 15 12:15:22 it's a *real* brick Aug 15 12:17:39 Thanks for your help! shame it died. Aug 15 12:52:17 Hi, I'm having problems with my uEnv.txt file. It works when I run from the SD card, but it can't find my .dtb file when it's flased to emmc. Could anyone give me advice on how to debug this problem please? Aug 15 12:52:27 I'm using this uEnv.txt https://github.com/jumpnow/meta-bbb/blob/pyro/scripts/emmc-uEnv.txt Aug 15 12:52:32 hi again thank you for your latest very good feedback Aug 15 12:54:09 I have a problem in Beagle bone, i am using jessie, and tightvncserver to have the display on a remote pc. My issue is the keyboard, can you help me to set the keyboard, when i type azerty, i get a*v.. Aug 15 12:58:51 ?? Aug 15 12:59:08 can you help me on this keyboard issue? please Aug 15 13:28:26 hi everybody, really sorry to disrupt you?My issue is the keyboard, can you help me to set the keyboard, when i type azerty, i get a*v Aug 15 14:08:43 Hi, how can I tell u-boot to find my uEnv.txt file? it won't find it when it's flashed to the partition 1:1 Aug 15 14:51:38 hi. i have problems with the debug header: Aug 15 14:52:06 i've built a custom base board for the beaglebone which adds a few peripherals and power among other things. Aug 15 14:52:52 when the bbbw is not mounted on the board i get output on the debug pins. but when the board is mounted, the leds flash the same way, but no traffic on the debug pins Aug 15 14:53:28 is there any logic in this? could i do something with the exp headers (P8 and P9) that cause this behavior? Aug 15 14:54:17 if i recall correctly uart0 is used for the debug pins, and they are not availble on the exp headers Aug 15 15:14:41 never mind! rotating the board 180 deg is never a good idea! Aug 15 15:36:44 Does anyone think they can help me with a php related problem? Aug 15 16:09:20 tbr: yes, rev B1 on the X15 board is still a rev C. Aug 15 16:10:20 jkridner: huh? yes, I know that, you explained that. Aug 15 17:04:00 x15 shipping image posted on https://beagleboard.org/latest-images/ Aug 15 17:04:29 tbr: sorry, I get asynchronous notices sometimes by e-mail. Aug 15 17:04:40 tbr: not that I always respond to them. Aug 15 17:06:08 jkridner: btw, any significant differences between the silicon on the early boards (e.g. what I have) and revC? Aug 15 17:07:18 yeah, lots of fixes between A2 and C silicon. Fixing one of the gigE ports being most notable. Aug 15 17:07:56 http://www.ti.com/lit/pdf/sprz429 Aug 15 17:08:53 looks like most items in the errata haven't been fixed in SR2.0 Aug 15 17:09:02 so, maybe not so much. Aug 15 17:09:32 mmc write speeds Aug 15 17:10:01 mmc2 pu/pd contention Aug 15 17:10:19 McASP to EDMA synch level Aug 15 17:10:59 the noted RGMII2 limitation to 10/100Mbps Aug 15 17:11:33 think that's about it that impact this board. Aug 15 17:17:25 jkridner: ok. good to have a rough idea if people come here with questions and I get around to dusting off mine to help them. Aug 15 19:46:56 hi all Aug 15 19:50:51 using beagle bone jessie, in LXQT settings, in 'keyboard and mouse settings', in 'type in the following box to test your keyboard settings', the sentence which appears never represents my hitten keys, for example if type 'azerty' it displays 'a*gn..', can you help to fix this?
