**** BEGIN LOGGING AT Fri Sep 01 03:00:01 2017 Sep 01 05:07:27 Hi has anyone ported Marshmellow on BBG Sep 01 05:07:43 I am unable to find the dt patch file for BBG Sep 01 05:53:01 anyone around? Sep 01 05:55:49 I'd just like to ask how to flash the new beaglebone blue since it doesnt say in (https://github.com/beagleboard/beaglebone-blue/wiki/Frequently-Asked-Questions-(FAQ)#Im_running_an_image_off_of_a_microSD_card_How_do_I_write_it_to_the_onboard_eMMC_flash) Sep 01 05:56:53 And also, if someone knows anything about this port 443 connection refused, please let me know. Sep 01 05:57:31 I am connecting to my beagle thru usb cable and sharing the internet of my computer which is the university campus "eduroam" used in UK. Sep 01 05:57:53 I cannot apt-get update neiter git clone anything because of this 443 connection refused and it is pretty frustrating me... Sep 01 05:58:00 please I need help! Sep 01 07:55:28 hello. i got a question, is there a good way to count pulses with a module on the BBB? i know i could poll with PRUs but isnt there a counter somewhere? Sep 01 10:04:48 can i use timer4 to 7 to count pulses? or are those only able to sample frequencies? Sep 01 10:07:34 and do the time counter registers exist in the file system somewhere? or do i have to access the HW registers directly to read them? Sep 01 10:08:01 i am a bit confused and have trouble finding any use case examples for this. Sep 01 10:55:50 Desperate_Dude: the eQEP modules can do that Sep 01 11:39:36 zmatt: it can? do i need to change a setting somewhere? it would only count with both inputs. but i wanna count just pulses, not in a quadrature encoded way. Sep 01 12:49:30 mturquette: you can lay out the eMMC with 6 mil trace/space rules. Sep 01 12:49:49 see https://github.com/beagleboard/beaglebone-blue Sep 01 13:03:51 Desperate_Dude: eQEP can also be configured to just count rising and/or falling edges on the A or B input Sep 01 13:04:01 I think the kernel driver supports it too, but I'd need to check Sep 01 13:06:29 yeah, you can configure that in DT Sep 01 13:09:19 correction, it can only count on edges of the A input, the B input can only be used to determine whether to count up or down (in mode 1) Sep 01 13:09:42 if you want to count up on rising edges, use count_mode = 2; Sep 01 13:25:01 mturquette: I'm pretty sure none of the beaglebones use HDI ? Sep 01 13:55:20 Hello, I have a BBB with the latest Debian 9.1 2017-08-24 LXQT. When I change a CPU frequency governor in /etc/init.d/cpufrequtils from "performance" to "ondemand", the setting is still "performace" after a reboot. Is there any other script setting it back to "performance"? (Changing in runtime via "cpufreq-set -g ondemand" works flawlessly.) Sep 01 13:56:14 I tried searching files for the word "governor" in the entire / , but ended up with an unresponsive system Sep 01 13:57:50 and I have a fresh Debian image installed, no changes, except upgrading via apt-get dist-upgrade Sep 01 14:33:21 a boot log and a /etc/init.d/cpufrequtils configuration file: https://pastebin.com/5YqLLFNR Sep 01 14:34:35 the boot log reveals a cpu governor setting error, I would be grateful for suggestions how to diagnose this further Sep 01 14:36:30 DVDR9: I'm more concerned about that stack dump in your kernel log Sep 01 14:37:27 not sure about the cpufreq thing, I think it ought to work like that Sep 01 14:55:56 zmatt: Thanks for seeing the log. If there is anything more I can provide, let me know. Is it something I should worry about? Sep 01 14:58:30 a traceback appearing in the kernel log is always bad. I've never seen this particular error (sysfs: cannot create duplicate filename '/bus/platform/devices/4a300000.pruss'), maybe it's trying to load an overlay to enable pruss while it's already enabled in the main DT ? Sep 01 14:59:19 looks like it happens while loading one of the drivers for remoteproc-pru Sep 01 15:06:34 zmatt: I am afraid my Debian and BBB knowledge is limited, but I all I did after image installation was setting a timezone, upgrading the packages and disabling GUI using systemctl Sep 01 15:07:19 and since I have the Rev. C of the board, I hope the CPU is not damaged Sep 01 15:07:45 (if this seems to be rare) Sep 01 15:09:47 this is a software problem, not a hardware one Sep 01 15:11:08 if it's like this on a clean install then I guess there might be an issue with that image Sep 01 15:11:27 btw, if you don't want a GUI, you might want to consider downloading the "iot" image. that also saves a lot of space Sep 01 15:12:20 if you're not using remoteproc-pru, you can disable it in /boot/uEnv.txt . that would presumably get rid of the problem Sep 01 15:12:33 is there a full yocto i could pull down for the current BBB? Sep 01 15:15:34 isn't building your own system the whole idea behind yocto? Sep 01 15:18:56 zmatt sure, i just want to see a full distro in action Sep 01 15:19:27 zmatt i'm still a newb at yocto, looking for a good example Sep 01 15:22:43 I think TI's "processor sdk linux" is built using yocto. I have no idea whether it serves as a good example or not Sep 01 15:22:56 but that's at least a prebuilt image you can download Sep 01 15:23:31 ok i'll check there, thanks Sep 01 15:24:29 config-pin is BB specific, is the a generic linux way to config the pins? Sep 01 15:53:57 zmatt: Thank you for all the tips. I will probably try the IoT image in the evening. Sep 01 16:06:19 zarzar: make a custom device tree Sep 01 18:18:19 zmatt good call, device tree it is Sep 01 18:19:26 zmatt i found some info on PINCTRL: https://www.kernel.org/doc/Documentation/pinctrl.txt\ Sep 01 18:20:01 zmatt have you ever used pinctrl? Sep 01 19:28:47 you're looking at docs for the kernel interface, the DT docs are in https://www.kernel.org/doc/Documentation/devicetree/bindings/ Sep 01 19:35:24 for examples you can look at the existing DT sources for the beaglebone... for some reason they often still seem to use raw hex values though, which I think is rather unreadable. I use some nice macros myself -> https://github.com/mvduin/overlay-utils/blob/master/spi0.dtsi#L15-L24 Sep 01 19:53:21 the /lob/firmware/ dir on my BBB has no dts files for some reason, only dtbo, no source Sep 01 19:53:25 lib* Sep 01 20:41:45 can i access emmc from a running sd image? Sep 01 21:00:53 any recomends for up to date device tree tutorials? Sep 01 21:41:48 the files in /lib/firmware/ are compiled *overlays*, the main device tree files are in /boot/dtbs - again the compiled versions, not the sources Sep 01 21:42:20 the sources for the main device trees are included in the kernel tree, although a more convenient way to tinker with them is using https://github.com/RobertCNelson/dtb-rebuilder Sep 01 21:42:39 the sources for overlays are at https://github.com/beagleboard/bb.org-overlays Sep 01 21:43:33 and mount /dev/mmcblk1p /path/to/mountpoint where the mountpoint is some empty directory (typically one uses a subdirectory of /mnt for it) Sep 01 21:43:41 mmcblk1p1 sorry **** ENDING LOGGING AT Sat Sep 02 03:00:01 2017
