After following the installing instructions,
I try to run

gulp --target=nRF51-DK

and i get the following error

any suggestions would be much appreciated?

Thanks

@pmcalabrese sorry for the delay - have you tried gulp --target=NRF51_DK - I think the mbed build tools expect the target name to be formatted in a specific way.

Additionally (I might be wrong, @janjongboom will know) - I don't think we've successfully run JavaScript on mbed with the NRF51 DK yet (either not enough RAM or Flash I can't remember), you might have more luck if you can get hold of an NRF52 board (that will then be gulp --target=NRF52_DK)

[janjongboom]

@pmcalabrese What Matthew says. Anyway, the nRF51-DK is not supported as it does not have 64K of RAM (minimum required for JS on mbed).

[pmcalabrese]

@matthewelse and @janjongboom Thanks for your support. OK, I'll grub a nrf52 dev board. But I still get the following error. I believe is some miss configuration.

Am I missing something?

[janjongboom]

@pmcalabrese Interesting error... I re-cloned this project and didn't run into this, although I needed jerryscript-project/jerryscript#1485 (but seems unrelated).

Some sanity checks, do you have the following installed?

• Git
• ARM Cross-compiler (arm-non-eabi-gcc should be in your path)
• mbed CLI

If not, is there an error above this that shows more info?

[pmcalabrese]

Thanks @janjongboom , i did some progress. I have installed ARM Cross-compiler (brew install arm-none-eabi-gcc ), mbed CLI (I already have Git) and Mercurial which is a dependency of mbed CLI. Now i'm closer to the compilation, but i get another error... maybe you can give some more hints:

when I try to run

gulp --target=NRF52_DK

i get

Hi @pmcalabrese, Yep that looks better. We fixed this yesterday by pinning mbed-js-gulp to a specific version of JerryScript (and it's fixed upstream in jerryscript-project/jerryscript#1485):

1. Run npm update.
2. Remove the build folder.
3. Run gulp again.

Build should complete.

[pmcalabrese]

Hi @janjongboom. It compiles, thanks for your help!

On OSX

What I've done is

• Install ARM Cross-compiler with brew

brew install arm-none-eabi-gcc

• Install Mercurial from https://www.mercurial-scm.org/downloads
• Install mbed CLI, very good docs here -> https://github.com/ARMmbed/mbed-cli#installing-mbed-cli

I already had git, python and node installed. Hope this can be informative.

[janjongboom]

@pmcalabrese Great, thanks! We'll release installers for Windows and macOS for mbed CLI soon, which should solve most of these problems.

[pmcalabrese]

@janjongboom after updating i still get this error

Error: Command `make BOARD=NRF52_DK EXTRAS=` exited with code 2

any suggestions?

[janjongboom]

@pmcalabrese Can you give the full log - perhaps in a gist?

[pmcalabrese]

@janjongboom there you go

https://gist.github.com/pmcalabrese/249a7de04b9e99dc13a4d71b43196a4c

[janjongboom]

@pmcalabrese Which version of mbed CLI are you running (mbed --version)?

I'm on mbed CLI 1.0.0 and it compiles for me... (when I manually patch in jerryscript-project/jerryscript#1512, as I didn't upstream it yet in mbed-js-gulp).

[janjongboom]

FYI, patched mbed-js-gulp in this commit which points to a newer JerryScript version.
