10:18 <Ramesh> hi

10:19 <Ramesh> what are the GPIO numberd for USR0,1,2,3 in beagle board x15

10:19 <Ramesh> leds USR0,1,2,3

10:20 <Ramesh> As per my understanding the GPIOs are GPIO7_8, GPIO7_9, GPIO7_14, GPIO7_15

10:21 <Ramesh> GPIO numbers are (7*32+8 = 232), (7*32+9=233), (7*32+14=238), (7*32+15=239)

10:22 <Ramesh> am i correct ?

10:23 <Ramesh> I am following the below steps to make USR0 led on

10:24 <Ramesh> 1) cd /sys/class/gpio

10:24 <Ramesh> 2) echo 232 > export

10:24 <Ramesh> 3) cd /sys/class/gpio/gpio232

10:24 <Ramesh> echo out > direction

10:24 <Ramesh> echo 1 > value

10:25 <Ramesh> USR0 led is not powered on after this...

10:25 <Ramesh> please let me know, am i missing something

10:26 <Ramesh> Refer page no 15 in https://raw.githubusercontent.com/beagleboard/beagleboard-x15/B1/BEAGLEBOARD_X15_REV_B1.pdf

11:32 <Ramesh> let me know if any one know the solutiobn'

11:32 <Ramesh> solution*

11:42 <zmatt> Ramesh: leds are controlled via led devices (/sys/class/leds)

11:42 <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

11:46 <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"

17:47 <Guest27> hello

18:59 <Konsgn> x

19:33 <Guest3380> Can you tell me when BBB01-SC-505 will be available?

19:42 <zmatt> you mean the beaglebone black? it's available right now

19:43 <zmatt> at least it was last time I checked

19:43 <zmatt> okay maybe I spoke too soon

19:44 <zmatt> mouser says they expect stock in march: https://eu.mouser.com/ProductDetail/BeagleBoard-by-Seeed-Studio/102110420?qs=vmHwEFxEFR8FZOWBwz8ZDA%3D%3D

19:45 <zmatt> farnell expects stock in january

19:47 <zmatt> Guest3380: okdo says they have stock right now: https://www.okdo.com/us/p/beaglebone-black-rev-c/

19:47 <zmatt> in general, just check the distributors listed in the "Purchase" menu here: https://beagleboard.org/black

19:48 <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 note that "BBB01-SC-505" is a GHI part number and no longer valid since the BBB is now produced by Seeed, not GHI

20:31 <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

20:32 <zmatt> yeah there's industry-wide availability problems of electronic components

20:35 <Guest3380> Thank you for your help.

21:30 <Konsgn> not enough cars to make chips from out there
