BBAI: pin P9_15 output failure #189

Open pdp7 opened 4 years ago

pdp7 commented 4 years ago

Reported in the Adafruit forum by jgomes78 and posting here so that others can see the issue and eventual solution:

I have a BeagleBone AI and I can't flash the LED on pin P9_15. I researched and verified that the mapping of the BB AI pins is different from the BBB.

Followup from jgomes78:

I thank you for your attention, I did what you asked for, updated Debian, tried again to make the led blink on pin P9_15 and it didn't blink. I am also sending the command response you asked for and the LED flashing program. In this program USR0, USR1, USR2 and USR3 flash, but output P9_15 does not respond.

blinkLED.js

#!/usr/bin/env node
////////////////////////////////////////
// blinkLED.js
// Blinks the USR LEDs and P9_15.
// Wiring: P9_15 connects to the plus lead of an LED. The negative lead of the
// LED goes to a 220 Ohm resistor. The other lead of the resistor goes
// to ground.
// Setup:
// See:
////////////////////////////////////////
const b = require('bonescript');

const leds = ["USR0", "USR1", "USR2", "USR3", "P9_15"];

for(var i in leds) {
b.pinMode(leds[i], b.OUTPUT);
}

var state = b.HIGH;
for(var i in leds) {
b.digitalWrite(leds[i], state);
}

setInterval(toggle, 100);

function toggle() {
if(state == b.LOW)
state = b.HIGH;
else
state = b.LOW;
for(var i in leds) {
b.digitalWrite(leds[i], state);
}
}

Good Morning! I tried other GPIO's, but the following message appeared:

info: No pinmux for P9_15 (node:2228) [INSPECTOR_ASYNC_STACK_TRACES_NOT_AVAILABLE] Warning: Warning: Async stack traces in debugger are not available on 32bit platforms. The feature is disabled.

The feature is disabled. error: Unable to write to /sys/class/gpio/gpio4/value

The feature is disabled. error: Unable to write to /sys/class/gpio/gpio35/value

I also tried again on P9_15 and the same message appeared. The USR LEDs flashed normally.

Grateful.

P9_15 is gpio76 on BBAI
