Serial Port Issues when running OctalBoneScript on newest debian

[murban1]

Good day,

I've recently been trying to run some code that I have successfully run on a previously setup beaglebone. I flashed a fresh beaglebone with the debian 8.5 from Here.

After successfully installing, I updated and upgraded and ended up with the following:

root@beaglebone:~/beaglebone# uname -a Linux beaglebone 4.4.12-ti-r31 #1 SMP Thu Jun 16 18:48:27 UTC 2016 armv7l GNU/Linux

npm -v 3.10.8

node -v v0.12.16

Everything looks good, but after installing octalbonescript with no errors, I try and run my code: DEBUG=bone node beaglebone.js Optional package 'serialport' not loaded /usr/local/lib/node_modules/octalbonescript/lib/serial.js:98 parsers: serialPort.exists ? serialPort.parsers : {} ^ TypeError: Cannot read property 'exists' of undefined at Object.<anonymous> (/usr/local/lib/node_modules/octalbonescript/lib/serial.js:98:21) at Module._compile (module.js:460:26) at Object.Module._extensions..js (module.js:478:10) at Module.load (module.js:355:32) at Function.Module._load (module.js:310:12) at Module.require (module.js:365:17) at require (module.js:384:17) at Object.<anonymous> (/usr/local/lib/node_modules/octalbonescript/index.js:11:14) at Module._compile (module.js:460:26) at Object.Module._extensions..js (module.js:478:10)

The last time I tried to flash and install, it was complaining about the I2C module in the same manner.

I'm not sure what would be causing this issue, so any help would be appreciated.

It seems serialport module is not loaded. It seems they have different versions for different platforms and kernels. Can you identify which one will suite OBS? https://www.npmjs.com/package/serialport

[dceejay]

the latest serialport 4.x compiles OK on node.js 6.9.x LTS... any chance of moving to that ?

[adityapatadia]

We can move to that but need to test the code once integrated. I currently don't have time for that. May be I will do after 10-15 days. Can you create PR?

Any progress on this? I have difficulty with npm i -g octalbonescript as well.

root@beaglebone:~# uname -a

root@beaglebone:~# node -v

root@beaglebone:~# npm -v

It tries to install but ends up with the following error:

I can provide the log file if it helps at all.

UPDATE: Looks like I forgot to use --unsafe-perm. So I tried that, and that supposedly worked.

@dceejay if I move code to newer serialport, can you check it on BBB? I don't have board around to check right now.

[dceejay]

sure

[adityapatadia]

I updated code in master branch. Can you check if it works on real BeagleBone?

[dceejay]

So far seems fine on both node 4.7.2 and node 6.9.5 (does have some deprecation warnings on 6.9.5 - but that is their problem not yours)

[adityapatadia]

Ok, I am releasing new version and closing this issue.

[dceejay]

Thanks very much.

Hi to everyone. I recently update my OBS to 1.3.0 and had the same issue as the one in the topic. When i load OBS by require command in my JS file, program crashes on line 98 of lib/serial.js

And i don't think the problem is because of serial module not loaded correctly! @adityapatadia

I checked changes on the serial.js file and found following changes on line 7:

-     var serialPort = bone.require('serialport').SerialPort;
+    var SerialPort = bone.require('serialport');

And after that line 69 was corrected in following form:

-               var port = new serialPort(path, options);
+               var port = new SerialPort(path, options);

But line 98 still in old manner: parsers: serialPort.exists ? serialPort.parsers : {}

So i changed it as following and everything is OK now: parsers: SerialPort.exists ? SerialPort.parsers : {}

My Beaglebone Black software and modules versions:

root@beaglebone:/# uname -a
Linux beaglebone 4.4.36-ti-r72 #1 SMP Wed Dec 7 22:29:53 UTC 2016 armv7l GNU/Linux

root@beaglebone:/# node -v
v4.7.0

root@beaglebone:/# npm -v

root@beaglebone:/# npm list -g octalbonescript

root@beaglebone:/# cd /usr/local/lib/node_modules/octalbonescript

I pushed v1.3.1 fixing this issue.
