input pin p8_44 to p8_41 and p8_31 issue on debian 8.x

hello, I use official debian images for my BBB. And since debian 8.4+ those pin : p8_44 to p8_41 and p8_31, does not do their job as INPUT pin. they can not fire CHANGE event anymore :

    b.pinMode(io, b.INPUT, 7, 'pulldown');
    b.attachInterrupt(io, true, b.CHANGE, function(x){
        console.log(io);
    });

I use 24 IO as INPUT and the others as OUTPUT for information.

I have tested it on 8.4 and 8.6 debian. same issue. but on 7.9 debian it works like a charm.

I also have tried it with original bonescript pkg on debian images and after an update to 0.5-rc (installed from debian repo) but same issue on debian 8.4+

for information I run with /boot/uEnv.txt on 8.4 and 8.6 : ##BeagleBone Black: HDMI (Audio/Video)/eMMC disabled: dtb=am335x-boneblack-overlay.dtb

and with that on 7.9: ##Disable HDMI/eMMC (v3.8.x) cape_disable=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN,BB-BONE-EMMC-2G

did you have plan to fix this ? thank’s a lot

don’t you assume that if it works on debian 7.11 and not on 8.4+, it is a regression ?

That sounds like a reasonable assumption to make.

you are right: internal pulldown mode seems not be activated by default on debian 8.4+ (but it does on debian 7.11). if I patch /usr/local/lib/node_modules/bonescript/src/hw_mainline.js on line 87 with : fs.writeFileSync(pinmux+"/state", 'gpio_pd'); it works

the pinMode bonescript api references that :

pin: the BeagleBone pin identifier
direction: INPUT, INPUT_PULLUP (under development on 3.8 kernel) or OUTPUT
mux: index to mux mode (under development on 3.8 kernel)
pullup: 'pullup', 'pulldown' or 'disabled' (under development on 3.8 kernel)
slew: 'fast' or 'slow' (under development on 3.8 kernel)
callback: called upon completion

and even if I try that test.js script, it does not work :

var b = require('bonescript');
var io = 'P8_41';
b.pinMode(io, b.INPUT, 7, 'pulldown');
setInterval(function() {
	b.digitalRead(io, function printStatus(x) {
		console.log('x.value = ' + x.value);
		console.log('x.err = ' + x.err);
	});
}, 1000);

don’t you assume that if it works on debian 7.11 and not on 8.4+, it is a regression ?
