Mac OSX issues seen with initial blink tutorial

[ajpowell]

Hi everyone,

Here are 4 issues that I have found when trying to compile my first Oak blink code and upload to my device - I have solutions to some of the issues (details below to help others hitting same problems and get folded into the code in due course) - because the uploader cannot find the particle config.json, I have not yet been able to upload my code to my device.

My environment:

• MacBook Pro running OSX 10.11.2 (El Capitan)
• Arduino IDE 1.6.7

These issues were encountered when compiling for the first time following the initial tutorial at http://digistump.com/wiki/oak/tutorials/arduino

The setup of the Oak device and connection to Particle has worked perfectly - the firmware appears to have updated.

Note - to differentiate the blink slightly from the default blink I see on the device, I have modified the blink code, so that the on time is much shorter than the off time, otherwise the code is as listed:

Code: [Select]

// the setup routine runs once when you press reset:
void setup() {               
  // initialize the digital pin as an output.
  pinMode(1, OUTPUT); //LED on Model A   
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(1, HIGH);   // turn the LED on (HIGH is the voltage level)
  Particle.delay(250);               // wait for a tenth second
  digitalWrite(1, LOW);    // turn the LED off by making the voltage LOW
  Particle.delay(1000);               // wait for a second
}
1. First compilation attempt failed with:

"/Users/apowell/Library/Arduino15/packages/digistump/tools/esptool2/0.9.0/esptool2" -quiet -bin -boot2 -4096 -iromchksum "/var/folders/9s/c2psyzzd6g73bn_7kth3cqvm0000gn/T/buildda9acfd3e334df2868c83c8c224f82f1.tmp/oak_blink.ino.elf" "/var/folders/9s/c2psyzzd6g73bn_7kth3cqvm0000gn/T/buildda9acfd3e334df2868c83c8c224f82f1.tmp/oak_blink.ino.bin" .text .data .rodata

FIX: From command prompt,

Code: [Select]

2. Recompiling then failed with the following:

So, now the compiler appears to have succeeded, but was unable to run oakcli

FIX: From command prompt,

Code: [Select]

cd ~/Library/Arduino15/packages/digistump/tools/oakcli/0.9.0/
chmod 755 oak

3. Error when trying to find the configuration file:

"/Users/apowell/Library/Arduino15/packages/digistump/tools/esptool2/0.9.0/esptool2" -quiet -bin -boot2 -4096 -iromchksum "/var/folders/9s/c2psyzzd6g73bn_7kth3cqvm0000gn/T/buildda9acfd3e334df2868c83c8c224f82f1.tmp/oak_blink.ino.elf" "/var/folders/9s/c2psyzzd6g73bn_7kth3cqvm0000gn/T/buildda9acfd3e334df2868c83c8c224f82f1.tmp/oak_blink.ino.bin" .text .data .rodata

Sketch uses 254,820 bytes (24%) of program storage space. Maximum is 1,040,368 bytes.
Global variables use 50,710 bytes (61%) of dynamic memory, leaving 31,210 bytes for local variables. Maximum is 81,920 bytes.
/Users/apowell/Library/Arduino15/packages/digistump/tools/oakcli/0.9.0/oak /var/folders/9s/c2psyzzd6g73bn_7kth3cqvm0000gn/T/buildda9acfd3e334df2868c83c8c224f82f1.tmp/oak_blink.ino.bin
Config file not found at: undefined\oak\config.json - please run the oak tool from the command line with no arguments to configure.

So this is looking good - compilation seems to have worked, just now unable to run the oak tool - it is mentioned in the tutorial that you need to run the oakcli one-time to set up the Particle credentials, so ran the oakcli tool from the version I had installed i.e. at:

Code: [Select]

~/Library/Arduino15/packages/digistump/tools/oakcli/0.9.0/oak
I was prompted for Particle username/password and selected my device from the list - the configuration was written:

Adrians-MBP:0.9.0 apowell$ ./oak
Particle Username/Email:particle.io@xxxx.xx.xx
Particle Password:************

[1] Unnamed Device (Device ID: )xxxxxxxxxxxxxxxxxxxx77f6

• CANCEL

Which device would you like to use? [1/0] :1
Configuration saved. You can now use this tool to upload files to your device.


4. Re-compiling and uploading then gives the following - still saying config not found:

Sketch uses 254,820 bytes (24%) of program storage space. Maximum is 1,040,368 bytes.
Global variables use 50,710 bytes (61%) of dynamic memory, leaving 31,210 bytes for local variables. Maximum is 81,920 bytes.
/Users/apowell/Library/Arduino15/packages/digistump/tools/oakcli/0.9.0/oak /var/folders/9s/c2psyzzd6g73bn_7kth3cqvm0000gn/T/buildda9acfd3e334df2868c83c8c224f82f1.tmp/oak_blink.ino.bin
Config file not found at: undefined\oak\config.json - please run the oak tool from the command line with no arguments to configure.

I notice now that the path that the tool is using is undefined\oak\config.json - this looks to be the issue, but not yet found a solution - doing a find across my whole system does not find an config.json file.

Does anyone have any ideas on the last issue?

[aja175]

"Config file not found at: undefined\oak\config.json - please run the oak tool from the command line with no arguments to configure."

there's a CLI tool that has to be run first to tell the IDE what oak device you're using.  Check the readme at the bottom for the osx version

https://github.com/digistump/OakCLI

[ajpowell]

Thanks aja175.

I did do this - just checked that the version on Github was the same as the version pulled down during the board install process -  oak -v reports v1.5.4 for both - it states that config is saved, but from Arduino IDE, it still shows:

/Users/apowell/Library/Arduino15/packages/digistump/tools/oakcli/0.9.0/oak /var/folders/9s/c2psyzzd6g73bn_7kth3cqvm0000gn/T/buildda9acfd3e334df2868c83c8c224f82f1.tmp/oak_blink.ino.bin
Config file not found at: undefined\oak\config.json - please run the oak tool from the command line with no arguments to configure.

I have now found the file - the contents of the directory now shows:

Adrians-MBP:0.9.0 apowell$ ls
oak            undefined\oak\         undefined\oak\config.json


My guess is that this is not the intended location of the file...looking in the source for oak.js at https://github.com/digistump/OakCLI/blob/master/oak.js, I see:

Code: [Select]

pathToConfig = (process.env.APPDATA + "\\oak\\" || (process.platform == 'darwin' ? process.env.HOME + 'Library/Preferences/oak/' : process.env.HOME + '.oak/'));
As this is a Mac, the platform should report as 'darwin', so should be using ~/Library/Preferences/oak...that directory does not exist - I did try creating this and copying over the undefined\oak\config.json as config.json - but this still fails - when the Arduino IDE calls oak, it isn't using that path.

Will try to set up node.js so that I can build oak cli for myself and see if I can figure out the problem...though only dabbled with node.js a few years ago.

[aja175]

 undefined\oak\config.json

There's probably supposed to be a file path there.  Undefined doesn't bode well for it working.

[ajpowell]

I have been setting up node.js as detailed in issue #1 for the oakcli repository - I think I now have it working for OSX and can run in node, but can't yet get nexe working.

First the fix - probably a bit of a hack (javascript is not my forte):

Problem on my environment is that APPDATA is not defined (hence message given), so have modified the following line (line 10):

Code: [Select]

pathToConfig = (process.env.APPDATA + "\\oak\\" || (process.platform == 'darwin' ? process.env.HOME + 'Library/Preferences/oak/' : process.env.HOME + '.oak/'));
to:

Code: [Select]

pathToConfig = (process.platform == 'win32' ? process.env.APPDATA + "\\oak\\" : (process.platform == 'darwin' ? process.env.HOME + '/Library/Preferences/oak/' : process.env.HOME + '.oak/'));
So...added a test for win32 platform - if we are on win32, use APPDATA, if darwin (Mac OSX), using $HOME/Library/Preferences/oak, else (Linux) use $HOME/.oak - I also added a missing '/' in front of Library...

With some debug statements, I see that this now gives me:

pathToConfig: /Users/apowell/Library/Preferences/oak/

The config.json file is written to that directory.

Which is pretty much what I'd expect...What I cannot do is test on windows or Linux at the moment to ensure that still works...

Once I get nexe compiling, I hope that uploading the code will work...will report back later.

edit:
BTW, I am getting the following when running nexe:

Adrians-MBP:OakCLI apowell$ nexe -i ./oak.js -o ./oak
....> ERROR: option nodeConfigureArgs was empty

In the comments section of the kickstarter comments page, DarkLotus has posted a link to his pull request for oak-cli (which includes a link to a binary for OS X). I've been able to flash my board, but it does not blink right now. So maybe it's better to wait

Issue created for the Fatal 28 issue on github
Linux and osx copies of oakcli built with path fix can be found at https://github.com/digistump/OakCLI/pull/2 for anyone eager.

[ajpowell]

Hey @djflix,

Good spot - I hadn't seen that!

I pulled it down and ran it standalone - works fine and save config in the correct location.

Copied the oak binary to:

Code: [Select]

cp oak ~/Library/Arduino15/packages/digistump/tools/oakcli/0.9.0/
And re-ran the Arduino IDE compile/upload again and it reports success:

Sketch uses 254,820 bytes (24%) of program storage space. Maximum is 1,040,368 bytes.
Global variables use 50,710 bytes (61%) of dynamic memory, leaving 31,210 bytes for local variables. Maximum is 81,920 bytes.

Sending file to cloud, to flash to device.
Device flashing started successfully.

However, I think my fiddling (which included running the non-nexe version of oak and pointing to the build output oak_blink.ino.bin) has bricked the device (doesn't flash at all now) - just as well I bought 10 of them!  Will hopefully recover the first device later...

[ajpowell]

Using a second Oak, it did appear to upload to Particle and claimed success, but I see no blinking at all.

I have now hooked up to the serial lines and once I had the rate correct (115200-8-N-1), I see the following being repeated:

Code: [Select]

Fatal exception (28):
epc1=0x40001800, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00637ff0, depc=0x00000000
Not quite sure how to proceed from here - Erik does mention that instructions for this will follow in the release notes here: https://github.com/digistump/OakCore/releases - can't seem to get it to boot to WiFi Config as described in those notes either, so I guess I will have to wait until more details are published.

[digistump]

I think @ajpowell you already are aware of this - but for the record here - this is fixed in the newest beta release
