EACCES: permission denied, open '/sys/devices/platform/ocp/ocp:P9_31_pinmux/state' #154

Closed ludook closed 7 years ago

ludook commented 7 years ago

hi, I have just installed new debian 9.1 iot on my bbb. and I found this issue when my bonescript try to use p9_31 as GPIO_OUT :

Error: EACCES: permission denied, open '/sys/devices/platform/ocp/ocp:P9_31_pinmux/state' at Error (native) at Object.fs.openSync (fs.js:641:18)

/sys/devices/platform/ocp/ocp:P9_31_pinmux/state is missing (but P9_41 is present for example)

uname -a

Linux beaglebone 4.4.83-ti-r119 #1 SMP Thu Aug 17 06:39:24 UTC 2017 armv7l GNU/Linux

cat /sys/devices/platform/bone_capemgr/slots

0: PF---- -1 1: PF---- -1 2: PF---- -1 3: PF---- -1 4: P-O-L- 0 Override Board Name,00A0,Override Manuf,cape-universala

did you have a workaround ? thank's

fivdi commented 7 years ago

Here's a picture of the BeagleBone Black expansion headers taken from the BeagleBone 101.

If the Debian image is used with the default configuration then only the pins that are colored light green (Available Digital) and dark green (Available PWM) can be used as digital IOs. (An exception to this rule is P9_25 which shouldn't be colored light green and can't be used as it's reserved for audio if I remember correctly.)

ludook commented 7 years ago

hello, yes I know that, but if you load universala cape, you can activate all gpio on bbb, and you will have this configuration : cape-headers-digital

as you can see in my first post :

cat /sys/devices/platform/bone_capemgr/slots 0: PF---- -1 1: PF---- -1 2: PF---- -1 3: PF---- -1 4: P-O-L- 0 Override Board Name,00A0,Override Manuf,cape-universala

is it wrong ? because I have done that on my debian 8.7 and it worked

fivdi commented 7 years ago

Apologies for the delay in answering.

If a recent version of Debian is being used the pins that are normally reserved for HDMI video, for example P9_31, can be freed for usage as GPIOs by adding the following line to /boot/uEnv.txt:

disable_uboot_overlay_video=1

This is documented here.

Due to a recent change /sys/devices/platform/bone_capemgr/slots is disabled after U-Boot has taken care of overlays. See here.

ludook commented 7 years ago

Hi, thank's for your answer. I tried to use uboot like you say :

enable_uboot_overlays=1
disable_uboot_overlay_emmc=1
disable_uboot_overlay_video=1
uboot_overlay_pru=/lib/firmware/AM335X-PRU-RPROC-4-4-TI-00A0.dtbo
enable_uboot_cape_universal=1

but I get this error, when I try to set p9_41 as GPIO as INPUT :

/usr/local/lib/node_modules/bonescript/src/hw_mainline.js:84
    if(!pinmux) { throw p + " was not found under " + my.is_ocp(); }
                  ^
ocp:P9_41_pinmux was not found under /sys/devices/platform/ocp

I just flashed my BBB with debian_stretch_9.2_iot

thank's for your help

fivdi commented 7 years ago

I can't reproduce the error.

The following program successfully blinks an LED connected to P9_41 with a frequency of 1Hz:

var b = require('bonescript');
var ledState = b.LOW;

b.pinMode('P9_41', b.OUTPUT);

setInterval(function () {
  ledState = ledState === b.LOW ? b.HIGH : b.LOW;
  b.digitalWrite('P9_41', ledState);
}, 500);

The following program successfully prints 0 (the state of P9_41) to the screen:

var b = require('bonescript');

b.pinMode('P9_41', b.INPUT);
console.log(b.digitalRead('P9_41'));

Please post a complete program that can be used to reproduce the error.

I create a test.js file in cloud9 root dir with your test content :

var b = require('bonescript');
b.pinMode('P9_41', b.INPUT);
console.log(b.digitalRead('P9_41'));

and I've got in cloud9 console :

4:4:91-ti-r133

/usr/local/lib/node_modules/bonescript/src/hw_mainline.js:84
    if(!pinmux) { throw p + " was not found under " + my.is_ocp(); }
                  ^
ocp:P9_41_pinmux was not found under /sys/devices/platform/ocp

what's wrong ?

fivdi commented 7 years ago

I used ssh to open a terminal window on the BeagleBone Black and logged on as user debian. nano was used to edit files and the programs were started directly from the command line. Debian 9.2 iot was used.

I just tried the way you did with cloud9. Everything works as expected and this is what can be seen in the cloud9 console when the "input" test program is run:

Debugger listening on [::]:15454
4:4:91-ti-r133

Unable to open /dev/mem
ERROR: trying to disable motors before they have been initialized

I saw the same when running the program in a terminal logged on as user debian.

fivdi commented 7 years ago

I'm afraid I don't know why your system is behaving differently.

ludook commented 7 years ago

very strange. did you test it on a debian 9.2 iot "just installed" without any other config ?

I understand the js script error because :

there is no "ocp:P9_41_pinmux" ...

how can I see if the universal cape is loaded with this new uboot tool ?

fivdi commented 7 years ago

did you test it on a debian 9.2 iot "just installed" without any other config ?

Yes, with one exception. The following lines were added to /boot/uEnv.txt:

disable_uboot_overlay_emmc=1
disable_uboot_overlay_video=1

how can I see if the universal cape is loaded with this new uboot tool ?

I don't think it is being loaded, at lease not completely.

Does the command dmesg display and error messages that could help explain things?

Is there any interesting information in the files at /var/log?

What I find interesting about the output of dmesg is what's not there rather than what's there.

On your system the output of dmesg contains the following two lines directly beside each other:

[    2.083555] pinctrl-single 44e10800.pinmux: 142 pins at pa f9e10800 size 568
[    2.086098] wkup_m3_ipc 44e11324.wkup_m3_ipc: could not get rproc handle

On my system there lots of additional output related to cape-universal between those two lines:

Maybe there's something wrong with the boot loader. Does it help if the boot button is pressed and held pressed before and during power on?

Maybe there's information of interest sent to the serial port while booting?

ludook commented 7 years ago

you are right : keep "boot button" pressed fix the issue : I see now the gpio-of-helper in dmesg

and I understand why it did not work : I read this boot-modes and this comment boot sequence is :

  1. eMMC
  2. sd card [...]

and on my eMMC, I had an old distribution where uboot_overlays was not activated. that's why we did not see "gpio-of-helper ocp:cape-universal" in dmesg.

I flash my eMMC, and patch /boot/uEnv.txt, and it is working as expected.

thank's a lot for your help !

I close the issue
