Dec 17 10:18:44 <Ramesh> hi
Dec 17 10:19:22 <Ramesh> what are the GPIO numberd for USR0,1,2,3 in beagle board x15
Dec 17 10:19:35 <Ramesh> leds USR0,1,2,3
Dec 17 10:20:58 <Ramesh> As per my understanding the GPIOs are GPIO7_8, GPIO7_9, GPIO7_14, GPIO7_15
Dec 17 10:21:49 <Ramesh> GPIO numbers are (7*32+8 = 232), (7*32+9=233), (7*32+14=238), (7*32+15=239)
Dec 17 10:22:08 <Ramesh> am i correct ?
Dec 17 10:23:56 <Ramesh> I am following the below steps to make USR0 led on
Dec 17 10:24:05 <Ramesh> 1) cd /sys/class/gpio
Dec 17 10:24:15 <Ramesh> 2) echo 232 > export
Dec 17 10:24:30 <Ramesh> 3) cd /sys/class/gpio/gpio232
Dec 17 10:24:44 <Ramesh> echo out > direction
Dec 17 10:24:57 <Ramesh> echo 1 > value
Dec 17 10:25:28 <Ramesh> USR0 led is not powered on after this...
Dec 17 10:25:42 <Ramesh> please let me know, am i missing something
Dec 17 10:26:34 <Ramesh> Refer page no 15 in https://raw.githubusercontent.com/beagleboard/beagleboard-x15/B1/BEAGLEBOARD_X15_REV_B1.pdf
Dec 17 11:32:14 <Ramesh> let me know if any one know the solutiobn'
Dec 17 11:32:29 <Ramesh> solution*
Dec 17 11:42:09 <zmatt> Ramesh: leds are controlled via led devices (/sys/class/leds)
Dec 17 11:42:55 <zmatt> the corresponding gpios are in use by the gpio-leds driver in the kernel... the fact that you can export them at all is a bug
Dec 17 11:46:54 <zmatt> also, as a random note... changing a gpio to output should be done by writing "low" or "high" to the 'direction' attribute, which specifies the initial output level (since you cannot switch a pin to output without having a particular level to output) ... writing "out" to it is a deprecated synonym for "low"
Dec 17 17:47:13 <Guest27> hello
Dec 17 18:59:33 <Konsgn> x
Dec 17 19:33:07 <Guest3380> Can you tell me when BBB01-SC-505 will be available?
Dec 17 19:42:47 <zmatt> you mean the beaglebone black?  it's available right now
Dec 17 19:43:06 <zmatt> at least it was last time I checked
Dec 17 19:43:39 <zmatt> okay maybe I spoke too soon
Dec 17 19:44:38 <zmatt> mouser says they expect stock in march: https://eu.mouser.com/ProductDetail/BeagleBoard-by-Seeed-Studio/102110420?qs=vmHwEFxEFR8FZOWBwz8ZDA%3D%3D
Dec 17 19:45:43 <zmatt> farnell expects stock in january
Dec 17 19:47:02 <zmatt> Guest3380: okdo says they have stock right now: https://www.okdo.com/us/p/beaglebone-black-rev-c/
Dec 17 19:47:40 <zmatt> in general, just check the distributors listed in the "Purchase" menu here: https://beagleboard.org/black
Dec 17 19:48:10 <zmatt> note that "BBB01-SC-505" is a GHI part number and no longer valid since the BBB is now produced by Seeed, not GHI
Dec 17 20:31:20 <Guest3380> Digi Key and Mouser sights say they have on order but will not be available until April/July 2022 So the bought is still active it seems
Dec 17 20:32:17 <zmatt> yeah there's industry-wide availability problems of electronic components
Dec 17 20:35:06 <Guest3380> Thank you for your help.
Dec 17 21:30:38 <Konsgn> not enough cars to make chips from out there
Dec 18 00:51:49 <outrageous> Real chips made from steel!
